MAYBE an answer to Thunderbolt issues with 4G ?

I posted this in another thread, but it might be interesting in it's own thread:
It IS a problem, but NOT every Thunderbolt has this issue.    Mine did.   It was 100% stock, not rooted or anything.   After the update, it started rebooting on its own.   I tried the remove battery trick, didn't help.   Removed new applications since the update, didn't help.    Did the factory data reset....and it's been perfect since relative to reboots.
I do still get the phone showing 4G service but no data connect, and no fall back to 3G until I get out of the 4G area.    I may have found a fix for that too... Hasn't been long enought to really test this out...but using the suggested ##778 (EPST edit mode) and I set the Preferred Mode to CDMA HDR and the Preferred Mode (9k) to HDR LTE mode.    Prefered had been at CDMA and preferred 9K had been at LTE only.
For the rest of yesterday....that seem to help A LOT.    But once I left work, I'm out of the 4G area, so hard to tell if it really helped or if it was just a quirk.    3G is fine, as it always has been.
As usual, your mileage may vary, don't forget to COMMIT the modfications and always...ALWAYS write down what the original settings are before you change anything!

Holy cow. This is flippin' scary. I'm at work and just made the changes you suggested. This thing has a stable 2 bars of 4G inside the building in my office. It seems to be real too, because web pages load quickly and email works every time. As a point of comparison, just 10 minutes ago before the config change, I was getting the normal random 3G/1X shuffles and complete dropouts, and never got a 4G connection in here. I will have to keep an eye on this to see if it holds, but this is the only thing the has made any sort of difference so far. Fingers crossed!
BTW, how did you know about this?
I didn't "know" about it, just made sense to me to try it.
It may have been the reboot of the phone that made the difference.   I do know if you've got crummy connections, rebooting does seem to help.    But hopefully, this change makes things a bit better.
So far, it is 'better' but not "good' with my phone, but I'm in a fringe area for 4G.
Oh yea...the bars you see for reception are for phone, not data (at least that's my understanding), especially for 4G since it uses a totally different radio in the phone for 4G reception.

Firewire to Thunderbolt Issues with External HD

I purchased the Iomega eGo BlackBelt portable HD (http://www.amazon.com/Iomega-BlackBelt-FireWire-Portable-35115/dp/B0041EM9XM/ref =pd_sxp_f_pt) a few years ago and have backed up my MacBook Pro using time machine. The cable is a firewire 800 with theses connections (http://www.newegg.com/Product/Product.aspx?Item=12-200-730&Tpk=N82E16812200730). The rounded side goes into the MacBook Pro. I am trying to get it to connect to my new MacBook Air with Thunderbolt. The Apple Firewire to Thunderbolt addapter does not fit the one end of the cable. So I purchased the Belkin Firewire 9-9 Pin Cable (http://www.belkin.com/us/F3N418-APL-Belkin/p/P-F3N418-APL;jsessionid=89030857685 109325329E6412E872E81) to use instead of the one that came with the HD. However, there is no power going to the HD. I've tried the split USB also with no luck. It powers with the original cable on the Pro, but not the Belkin cable and Apple adapter on the Air. Any suggestions?

You can go on about your mistrust of eSata to Firewire bridges, etc., but my experience
.......internal configuration of the Iomega drive
What changed?
Erratic performance
1. Iomega doesnt make HD, there are only 4 HD (conventional) mfg. on earth current, Hitachi, Toshiba, WD, and Seagate. The HD in the older Iomega is a Samsung not made anymore.
2. Youre presuming its "my mistrust of SATA bridge hardware" or a subjective limited conclusion......its not.
Its an empirical fact that SATA bridge hardware in USB to SATA HD or (little used, little owned) Firewire to SATA HD is "the most UNTRUSTWORTHY storage failure point that exists"
3. Erratic performance........thats why some of us call it "haunted hard drive" syndrome. The HD acts illogical, power and issues with appearing in disk utility.......logical diagnosis becomes 'hard' because the SATA interface has often no straightforward ABC.... failing profile.....
I answer no less than about 40 questions a month here that are related to failing or failed SATA bridge cards.
Ive got no less than a dozen dead ones laying around the house.
In fact in one day (no joke) I had 2 SATA bridge cards die on me. Confirmed that it was the bridge cards.
This hardware USED to be permanently attached to USB hard drives, but the mfg. realized this part failed SO much SO often they made it a detachable part.
SeattleLonginTheTooth
What might we infer from this?
Possibly the Thunderbolt adapter alone isn't supplying adequate or stable power,
"my experience" is a lot more extensive with external HD media.
Yes, and that also indicates SATA card issue.......which manifests in 2 ways most often, recognition issues and power drop "lost HD" issues.
the SATA bridge card as found inside USB HD devices which has an extremely high failure rate.
Inside a USB hard drive, containing the HD and SATA card
Countless 1000s of good external hard drives are thrown away each year because the owner thought the HD was bad when it fact it was the SATA bridge card which had failed. This card is removed in a matter of mere second once an external USB HD is cracked open from its plastic casing to reveal the bare HD and the attached SATA card which attaches between the HD and the USB cable.

Having issues with Flash in Opera

I have been having issues getting videos to work in my browser. I use Opera and it will not load anything Flash related. It gives me an error telling me to install the latest version of flash despite the fact that i have the latest version. If i load IE it loads videos with no issues. I have tried searching to find an answer to this issue with no succes. Seems like it may be a problem with Opera but i cant find anything related. I run AVG antivirus and the scan is clean. I also ran Malwarebytes which came up clean as well so i dont believe it to be a virus or anything of the sort. Any help would be appreciated.

Strange issue with external monitor, only working when external speakers plugged in (using Thunderbolt to VGA adaptor)

Hey – I am having a very strange issue with my external monitor; where it only works if my external speakers are plugged in and connected.
I am using a late 2011 Macbook pro, running Mavericks 10.9.4, along with an MBox 2 (USB Audio Interface), and two powered speakers (KRK Rokit 5). This setup has had no issues. I have just acquired an external monitor (Benq T2200HD), which I am using with a thunderbolt to VGA adaptor (a cheap Chinese knockoff adaptor).
To start - I plugged the monitor in with the thunderbolt adaptor, and it powers up and works fine. However, there is a nasty buzz coming from the speakers. I did some research and it looks like a simple ground loop issue. I did a bit of troubleshooting, and this is where things get weird.
What I found is - If I unplug the MBox, the monitor loses signal from the computer (displaying ‘No Signal Detected!’). Further, if I keep the MBox plugged in, however unplug both the cables from the MBox to the speakers, the monitor loses signal. It doesn’t matter if the speakers are turned off, however they need to be plugged in (or the monitor loses signal). Weirder still, I can unplug the MBox, however the monitor will work if I plug in the speakers through my macs headphone jack.
Simply put, the monitor only works if there is a direct connection between the computer, the speakers, and the power source. What is going on here? Is the monitor grounding through the computer port, to the speakers (I don’t know how this works, is this possible?). Could it somehow be the cheap VGA adaptor I am using?
Some other information:
- Everything is plugged into the same multi-box for power. I have tried plugging things into separate sources, and the result is the same.
- If I unplug the thunderbolt adaptor, then the speaker noise disappears straight away.
- The ground noise doesn’t appear in my headphones, which are plugged into the MBox.
Any information would be great – am I missing something here, or is this genuinely weird?

Well, I went back into Best Buy to test on 3 other laptops (2 Asus, and their floor model for this Sony). It seems to be doing the same problem so at least I was able to rule out broken hardware issue on my particular laptop.
Here's what I did to test:
Since I couldn't really install Adobe Premiere on their machines, I used the DVIO software (http://www.carr-engineering.com/dvio.htm) and a 5 min clip I captured. I transferred onto their machines, hooked up my Sony D8, and attempted to play the video. It would play for 15 seconds and then stop and jitter with a loud noise (like it does on my laptop). I even tried changing each machine's firewire driver to the legacy one and same results. I pulled a brand new 4 pin to 4 pin firewire cable off their shelf and still the same problem.
I think I've nailed it down to Win7x64 bit Home Edition not playing nice with Firewire driver. Very annoying. I can't find any concrete evidence of this from other users on any of the forums that have my particular problem, but from my own testing, it's all I can conclude.
I have 2 other things I can try:
1. Opening the laptop and looking at the firewire to maybe find appropriate driver (ugh, I don't want to have to open this thing up).
2. Upgrading to Win7x64bit Pro and possibly testing with XP on the new MS Virtual PC (http://www.microsoft.com/windows/virtual-pc/). I can't do it with my Home edition apparantly.
Who needs to view video on an external TV anyways....sheeesh...(scarcasm).

Ram Issues with a Hp Pavilion a6357c or maybe the amd athlon 64 5000+

I am really not sure if I am in the area-of a post like this. Please excuse my grammar and spelling"will try and use spell check"...
I got this computer from a friend of mine.Total nightmare. Was told all it needs is a hard drive and maybe a video card..Boy was that not the issue. I first got it and plugged it-make sure it would boot to bios..Nothing computer turned on-fans and all..Nothing on the screen. To make a long story short...I found an old ps2 mouse..The mouse was defective...with that mouse plugged in-computer wouldn't even boot to bios..Fixed that issue. Got into bios and all was good. Next step..Video card-Bought a new pny 9500 GT and a TTGI 550 power supply....swaped it all out and it works great...Than found a hard drive SATA 2...everthing installed and ready to place an operating system on....
Windows 7 64 bit--Installed great...But when it came up to the start up---Freeze--blue screen...Ok thought maybe it was the ram.....ended up taking all the old ram out and replace it with some DDR2 6300--or what ever the max was...total of 6 gb...still issue...freezing--decided to boot into safe mode---all good and ran great....checked Ram-stress test-checked every little hardware--stress test-no issues...Booted back up out of safe mode... Same issues....ok--lets just try Windows 7 32 bit.....
Windows 7 32 bit.....Install went great-no issues....updated and all the sp's...but underload----bluescreen....played and played with it...but the blue screen were all over the place...back into safe mode and checked all the drivers--and devices....Ok lets just go back to what the system had----windows Vista....
Again----everything boot and installed perfect...This time was a liitle more stable...updates--all the sp's all the drivers.....
Blue screen underload......Ok maybe my ram is at fault.......
It ended up stable and working perfect---single channel mode-2 gb in the first slot....I tried every way to put the ram in.....
found out--ok---only stable in single channel mode...anytime I added ram--for dual channel...Fail under load....Put the 2 gb stick or a 1 gb stick any any of the other slots-by itself---perfect stable and running great...I was even able to add another 1 gb stick with the 2 gb stick---but it had to be in single channel....tried to add more in single channel and fail....3 is it and it is not all the way stable--but stable enough to run...2 gb stick by itself---perfect.........
Did some digging---maybe it is the memory controller...But can not find any post with this issue---I keep finding people asking the quesion--and there storys match...But no answers and it seems that the just get a walk around.....
I have narrowed it down..It has to me the intergrated memory controller on the chip....so i think...I could just purchase a new one and swap it out........But here is the issue...........
Safe Mode will take all the ram-dual channel---single channel..anyway.......But so will linix-----Only has this issue with Windows....
The other werid item too---My had drive say scis drive or something along that lines--Not sata.....and again-I can not find a post to explain why......
Please understand----Stress test on Ram-cpu-motherboard--videocard----everthing--is perfect no issues...PSU is perfect---checked it out in another sytem---no issues....I am at my witts end with this thing and I have got nowhere......
It is working great with just a 2 gb stick of ram---very fast and very responsive....But adding extra ram really bothers me...Not because--it make a differance-Just because I don't know...
Can somebody out there school me.....I have tried everything........

Sorry all-But i never got a reply to this situation. But I am done. I ended up running threw tons of post and tons of threads. I can tell you that when people ask a question. There is always some smart A--, telling them something that has nothing to do with the current situation. I guess alot of people out there think they know everything- and have nothing to do-but mess with the people like me when they are stumped. Anyways...I ended up running a computer check in or after bios...I think they call it burned in-HP....what ever-the last straw when you can not figure it out..Ran it with one stick---than with all the sticks..Everytime--it claimed that there was nothing wrong..But when I tried to restart it--boom blue screen..with the mulyi sticks of ram. So when I couldn't find an solution online...I stoped using the words HP a6357c.. and just typed the issue..Funny thing the issue kept poping up--and with the same motherboard or processor...and again-nobody ever came up with a solution..Most of the post claimed the issue was the power supply....ot the ram timming..But I know better..Not to mention people kept saying-buy the tool from ebay to check wattage usuage.....Bam----wattage...Did a simple check with harware monitor...my 3.5 or 3.3 rail was running at 1.78....enought to power one stick of ram---not 2...or barley enough to power a 1 gb stick and a 2 gb stick in single channel mode...Again-people were blaming--PSU"not my case".Ram Timming.."not my case".........Then I found a person with the same make and model.....Look for fat or bad capasitors...Never thought of that.....Guess what------That is what I found....No body but a thread-one thread has explained...If you have this same issue-Look at the capasitors...Maybe this is a defective motherboard--you can not find it on the site anyway-no specs nada..like it was a mistake..So if you have one just like this- I have a feeling-you will run into this issue-in one way or another..I just don't understand why both companys have no fix--or no--recall info..No answers to problems on these....now I have a big black paper weight.....sorry for my spelling and grammer-just so mad..the net was no help on this

Major Issues with Thunderbolt Display in Yosemite

I have a MacBook Pro (Retina, 13-inch, Early 2013). I'm having issues with thunderbolt display connectivity despite recent Thunderbolt Firmware update. The sleep wake function is not working and display with shut off sporadically.
MacBookPro10,2 Processor Name: Intel Core i7 Processor Speed: 3 GHz Number of Processors: 1 Total Number of Cores: 2 L2 Cache (per Core): 256 KB L3 Cache: 4 MB Memory: 8 GB

Same problem here. I was so excited to see a firmware update this morning for my mac pro, and sure enough as i sat here, the display went black again.

Sync issues with Thunderbolt drives

I'm checking to see if there are any sync issues with Mac Book Pros pre-Retina screen.
I have a (13-inch, Mid 2012) 2.5 GHz Intel Core i5 Mac Book Pro and I'm having some sync/latency issues with a number of audio interfaces, including a Symphony I/O and a MBox Mini 2.
I'm editing with Final Cut Pro 7. Mavericks OS 10.9.5. It's also happening with QT 10.3.
I'm using a Thunderbridge with the Symphony I/O and the USB port for the MBox Mini 2, but it has the same issue. I'm trying to get the registration number for my Pro App version of QT 7 because QT 10 is having some issues with a few arcane video formats. Is that possible? I can't retrieve the email because the computer that might have it is long dead, and buried in storage.
configuration:
Mac Book Pro to
G RAID Studio (via Thunderbolt) to
(Apogee Symphony I/O Thunderbridge)
1080P monitor (via Belkin Mini Display port to HDMI cable)
or MBox mini via USB
Both of these setups have sync issues. I have rigged a 1/8" stereo plug out of the headphone output and except for the occasional deafening buzz when you touch the adapter, it works okay, with no seeming sync issues.
Is this a thing? I understand that there is an issue with Symphony I/Os and certain Haswell Mac USB 3.0 ports.

Hi,
Yes, I apologize. The video editor wasn't giving me any details. I did see the 44.1/48khz issue online. So will this happen only if both are mixed in the same timeline?
Thanks

HT5219 When can we expect a fix for the Windows 8.1 hot-plug issue with a Thunderbolt device.

When can we expect a fix for the Windows 8.1 hotplug issue with a Thunderbolt device. I got a dock to easy my up-and-go time when moving from using my laptop on the desk vs in meetings. Instead my computer crashes and I have to reboot.
I am seeing this issue with the 2012 Macbook pro Retina running Bootcamp with Windows 8.1 x64 bit with the F4U055 Dock from Belkin

I can confirm that hotplug does work properly on Windows 8.1 with Asus Thunderbolt ExII (Thunderbolt 2)
But does not work with Windows 8.1 and MacBook Pro Retina (Thunderbolt 1)
To get hot plug working with the Asus Thunderbolt ExII, you install the intel thunderbolt drivers, and then you get an interface where you can eject devices, and do things like setup more detailed security. However, this doesn't have any effect with the MacBook Pro. I suspect that either:
1) Apple's Thunderbolt hardware doesn't support hotplugging on windows
2) Hotplugging on Windows requires Thunderbolt 2
So, I should check on my Mac Pro (dustbin edition) to see if it works there with Thunderbolt II
Be great to hear if anybody has any success with this on an Apple device!

Why are there no answers to the wifi issues with iOS 7.0.4

Why isn't Apple addressing the issues with wifi connectivity, or lack there of, with iOS 7.0.4? Everyone is complaining, but no one is answering. Don't tell me about turning on and off of wifi and router...been there. Come on apple...give us some help here. And why will my iPad 2 connect to Apple but absolutely no where else?

Issue with Adobe maybe?

Hi,
So I am having issues with adobe reader. I work as tech support and someone called in with issues. His issue is:
Cannot open forms and enter information then save them back using his program. The webprogram he is using is JIDS. JIDS requires that the pdf be opened in the webbrowser. This is so it can be saved back to their database or whatever.
The issue is when he tries to open the document in ie it opens it on his local adobe program not in the browser. I checked the addons and adobe will not appear there. (in any of the catagories plz do not reply im in the wrong view or whatever) If I open a force ie to open a pdf nothing appears (makes sense because it says there is no addon). I have uninstalled and reinstalled adobe multiple times from adobe.com (it is up-to-date) every time says installed successfully. This is a new computer and does not have older versions on it. I have removed it using the adobe cleaner then reinstalled no change. I tried reapplying the acropdf.dll using regsvr32 both in the 32bit and 64 bit locations (\windows\system32\ and \windows\sysWOW64\) and I keep getting an error that says loaded but dllregisterserver error 0x80070005. which is permissions error, but he is the only admin on the pc(local admin) and has full access, uac is shut off and i was using the cmd in run as administrator mode.
Since i couldnt find anything else on this I dicided to use firefox since ie and FF are only browsers allowed by JIDS. I downloaded newest FF and FF does say adobe reader addon is installed, but when i open the pdf in the JIDS program the fields are not editable and it has a popup ontop of the browser saying something about compatability issue and asks me to open with different program (clicking it opens the pdf in the adobe reader program and it is then editable but will not save back to the website, no supprise there).
He is using windows 7 64bit logging onto a domain. Using IE9 and updated adobe reader (11.0.03) and newest version of Firefox
Windows is fully up to date.
His computer is the exact same model as the one next to it that works perfectly fine and he hasnt done anything that could have messed up the system files (he knows he is bad with computers and doesnt do anything without asking someone else first). Mostly only uses the webbrowser and another program thats installed on there for him already.
I plan on installing adobe reader X or possibly older version of IE/FF to see if these might help. I also will be checking/disabling what he has for AV (i think its just windows security essentials but im not sure will doublecheck).
Any other suggestions on things to try? What is could be causing these issues?

Probable issue with the Firefox is that in the documentation it is poorly worded poorly, JIDS only support FF 17.
What is the issue with IE if that does fix the FF issue?

Please correct your porfile: iPhone 4 do not have IOS 6.1.4.
The usual troubleshooting steps are, also remember to test it after every step:
1. Restart
2. Reset
3. Restore from backup
4. Restore as new.

Mac Pro 6,1 STILL having issues with Open CL (4K scaling and SpeedGrade direct link grades)

I've seen the staff responses to the issues of the new Mac Pro GPU saying that 10.9.4 fixes everything. For me, it has fixed my export issues, so I'm glad. I'm no longer getting lines and artifacts on my renders.
That's great.
However, I'm still having several issues, and they seem to be linked to Adobe and Open CL.
Here's a video that shows what's going on:
mac pro issues july 7 - YouTube
Issue #1
Like most of you probably, I'm doing 1080p exports of most things I'm working on. The first project shows a 1080p timeline with a mix of 4k, 5k, and 720p footage. Because zooming in so much on a 720p file in a 4k timeline looks so crappy, I'm doing 1080p timelines and scaling everything to the size it needs to be. I started in a 4k timeline then switched to 1080p because the 720p footage looked so terrible. However, in the 4k timeline, I didn't have any of the issues I'm showing in this first part of the video.
When I switched to the 1080p timeline, I discovered a weird quirk: When I resize the 4k (or 5k) footage to the size it needs to be (which varies based on the frame I want), it goes back to the 100% view when I'm scrubbing through it. When I pause, the size of the video goes back to the way I set it. I show this in the video. Then I show what was my working solution for the time being: "scale to frame size", which brings all the videos to the size of the sequence frame size and works fine. Later, I turn off OpenCL in premiere and when I scrub through the video, it doesn't zoom back in or only stay at the size I set when stopped. For some reason all of these issues only happen at 50% scale or smaller. It doesn't happen at, say, 60%.
I've tested this with raw R3D files and other 4K (or 5K) clips (even clips exported from After Effects) and the same thing happens. It doesn't seem to happen with 2.5k footage or 1080p footage.
Issue #2
This is the second project you'll see in the video.
After grading in speedgrade (through direct link) I open my project back up in premiere and start playing it back. The video plays back with delays and frame drops. Now normally, this would be expected. But this is 1080p pro res footage, and this is just an effect added, and the yellow bar appears indicating that open CL should be accelerating the playback and it should do so smoothly.
Maybe I was just wrong in assuming that a simple grade from speedgrade would be able to playback smoothly. I turn off the grade, and it plays normally.
But then, when I turn off open cl and leave the grade on, the video plays back without ANY issues.
So to me, it seems I'm still having issues with Open CL and adobe. I've found fixes that make it work temporarily, I don't need that kind of answer. However, I would like this to work. Is there something I'm doing wrong? Something I need to do to get this to work?
Here are my specs:
Mac Pro 6,1 (Late 2013)
3 GHz 8-Core Intel Xeon E5
64 GB 1867 MHz DDR3 ECC
AMD FirePro D700 6144 MB (x2)
OSX 10.9.4
Firmware: 2.20f18
What you're seeing is latest version of Premiere (CC 2014, v8.0.0 [169] Build)
Everything here is ProRes 422, running from a Promise Pegasus2 R4 RAID (drives: 4x Seagate Desktop HDD 4 TB SATA 6Gb/s NCQ 64MB Cache 3.5-Inch Internal Bare Drive ST4000DM000) (that's thunderbolt 2).
I've done everything: I've restarted my computer hundreds of times, I've reset NVRAM and PRAM and done power cycles.
This isn't just some issue that started with 10.9.3 of OSX, the 4k issues happened when I first switched to a 1080p sequence back in February (2014) or so, which means it was an issue even with 10.9.2 and the previous firmware release.
I've reported this issue to adobe.

That crash appears to be casued by the Facebook plug-in.
Create a new account (systempreferences -> accounts or Users & Groups on 10.7 and 10.8), make a new Library in that account, import some shots and see if the problem is repeated there. If it is, then a re-install of the app might be indicated. If it's not, then it's likely the app is okay and the problem is something in the main account.

FireWire issues with external drive in Yosemite

I have just upgraded to OS X Yosemite, and I have an annoying problem with my 500GB FireWire external drive (which I use for Time Machine backups).
Basically, after updating the drive won't show up anymore, neither in the Finder nor in the Disk Utility. I also tried the "diskutil list" command in the Terminal, but it is nowhere to be found. Note that the drive does indeed receive power from the port - it spins - and when I look into System Report --> Hardware --> FireWire it does show up there (but I can't mount it). Furthermore, if I use a USB cable to connect the drive everything works fine, so the disk itself seems to be OK.
The funny thing is that if I boot with the drive plugged in the FireWire port the system mounts it normally. But as soon as I eject the drive, I am unable to mount it again (unless I switch to the USB cable, as mentioned above).
Prior to the update, everything worked flawlessly. For now, I backed up my Mac via USB 2.0, but it's very slow and I definitely don't want to resort to this workaround everytime. And it goes without saying that I don't like having issues with my primary backup device in general.
I already did all the usual troubleshooting (rebooting, resetting NVRAM and SMC, ...), but the problem still persists.
Any suggestion?

I had the same issue on a rMBP 13'', brand new 2015 March.
Two thunderbolt adapter connected: one for ethernet, one for firewire Lacie drive.
and...
even after taking the ext. Firewire on the Spotlight exclude list, and also after disabling sleeping hard drives, I always got the issue.
Until I realized that touching the laptop or moving the screen was immediately leading to disconnection.
Then I exchanged the thunderbolt connectors, and now it is stable and does not disconnect again.
??? Maybe one of the ports is more "delicate" than the other?
Big hardware weakness here...

MAYBE an answer to Thunderbolt issues with 4G ?
