Bluetooth stopped working after update to PR1.3

After updating my N9 to PR1.3 the bluetooth stopped working. Trying to connect it to my laptop or other phone is unsuccessful, only get "Transfer failed" message. Anyone has this problem, too?

Pearl 8130 Bluetooth stop working with GPS

Has anyone experienced a situation where your Bluetooth BlackBerry was paired with your automobile's GPS system and was working fine, then stopped one day and can't get it to pair up anymore? We have an 8130 that was paired to the car's GPS system perfectly then suddenly stopped working one day. After taking it to the car dealer and having them look at it they determined it was a problem with the phone. They were able to pair up another phone to the car without any problems. I took the phone and tried pairing it with another GPS system, that can pair up with another working BB, and was not able to get the phone/GPS to pair up either. Has situations like that happened before? What can be done about it, if anything?
Thanks.

Try performing a system repair using PC Companion as this will often fix issues - This will factory reset your phone and erase all data so best to backup before you begin
Switch off your phone and unplug from Pc (Hold volume up and power for around 10 seconds)
Start PC Companion and select Support zone then Update my phone/tablet then in Blue Repair my phone/tablet and follow the on screen instructions - When prompted connect your phone still switched off holding volume down or back button - This should start the repair or reformat process
If you are using Windows 8/8.1 or a 64bit operating system then adjust the settings for PC Companion and run in compatibility mode and chose Windows 7 or XP

W520 External Color Calibrator stopped working with updated Pantone v1.1 software

Can someone from Lenovo help me with this issue? Lenovo updated the color calibrator software in Aug 2012. They broke an external color calibrator working. L1/2 has been completely unhelpful. I also escalated to customer service with little result except that they say it is not Lenovo software and they do not have to support it! Unacceptable, the software isprovided by Lenovo. Lenovo doc also says an external color calibrator is supported. Lenovo needs to take responsibility for fixing this. Here are the email chains. I really want a refund or someone to ensure this package that Lenovo distributes is fixed!
Thanks for your help.

Hi Kelli,
I do not want this case closed and disagree. This is Lenovo provided software and according to Lenovo an external calibrator is supported. I want someone to take responsibility for getting this fixed. Lenovo has provided this software and needs to work with the vendor to ensure it works. Who do I need to speak to in management? I do not appreciate the way support has just shuttled this around and nothing has gotten done.
Sincerely,

Mr Lang,
Please be advised that I have taken this case assigned to Doris. Lenovo is not able help you with this issue, We cannot provide support for a third party product. The calibrator you are using is supported by X-Rite; any issues with the device need to be addressed by them,
I am sorry for your frustration however Lenovo has exhausted all means to help with a non-hardware issue. At this time Lenovo is closing this case.

Hi Doris, Thanks for your time, re: case 184142. Can we get this package fixed? Jeremy’s response below just makes no sense to me, same as that call center in Atlanta is so problematic. I work in IT and when I phone that call center I really wonder sometimes whether I am even speaking with another IT person on the other end of the line. These are Thinkpad, mines is an expensive one, and I am very upset that this is the level of support I get (especially after upgrading my warranty even!). Please see what you can do. I would also like a manager to speak to DeAndrea at the call center. I am sure the calls are recorded and he was completely out of line and not helpful. Just like now I wonder ‘why did Jeremy even contact me!’ what with the response below. Please phone me tomorrow as we discussed. Have a great day!

Error with latest update to Pantone Color Calibrator Software (v1.1) and Eye one external calibrator 09-19-201211:39 AM - edited 09-20-201209:10 AM Hi. Can someone have a look at the Pantone 1.1 package. I am using an eye one display calibrator with the updated Pantone software and the calibration does not work. I get an error about an 8 bit image missing (have attached a screenshot). The calibration is not correct and Windows Photoviewer is pink. This was working OK with the v1.0 of the software (no longer on the w520 driver page). The error message is "There was an error loading the specified profile. Please make sure the image has an embedded profile and it is an 8-bit image." This was working fine before the update to v1.1. Thanks

I am getting the runaround!!!
Hi Doris,
I just left you a voice mail. One of the reasons I bought this laptop was for 3d photography. If I cannot use an external color calibrator and display then the laptop is not fit for purpose for the reasons I bought it. This software is ONLY available from Lenovo. According to Lenovo’s own doc, and the software’s doc, an external color calibrator is SUPPORTED. Lenovo needs to step to the plate and fix this. Not ME. If Lenovo needs to go to Pantone, or x-rite, then they Need to do that. Lenovo provided software that is not available to the public from x-rite or Pantone, and the software is to support Lenovo provided hardware (least so far as the internal calibrator), this software ALSO supports an external calibrator for use with an external display. The software supports both internal and external, and I would like to use my external display for 3d photography. This needs to be fixed please.
What are we going to do to resolve this? At his point of the runaround I’ve been getting I would like a complete refund.
Thanks,
Christopher

Hi Kelli,
As you know the ‘software’ purchase is by virtue of purchasing the laptop with the color calibrator. Are you saying you will refund my cost for the calibrator? I don’t think you quite get how much time I have spent with support with this laptop. I have had multiple issues with the it. The calibrator, failed BT adapter, Sudden Shutdown syndrome (where the machine would just shutoff on its own –well documented in the Lenovo forums and I have at least a dozen emails on this issue) as well as many issues with the Displayport connection and an external 3d display for which I spent months working with Nvidia to resolve. This laptop has wasted a huge amount of my time. The support has been atrocious.
I would like a refund for 1. The laptop 2. The external color calibrator I cannot use because the software from Lenovo does not work (this package is NOT available from x-rite as well –It is sold to Lenovo). I have a receipt for the color calibrator and would be happy to provide that.
Thank you,

Bluetooth stopped working after updating to iOS 6.1

Yesterday I update the software on my iPhone 4 to iOS 6.1 and after starting back up it would not find my bluetooth headset (that I've used for the last year). It will not find any bluetooth devices. Previously, it would locate my headset, iPad, and iMac but now it lists them but will not connect and only shows a continuous search. The bluetooth icon is gray in color.
I've turned the phone off and on several times, and also done a hard reset twice - the results have been negative.

Try going into setting> General> Reset> Reset Network setting and if that does not work try reset all settings.

Voyager 510 Bluetooth stopped working with YouTube after 10.6 upgrade

I have been using a Plantronics Voyager 510 Bluetooth headphone for several months. On 10.5.8, it worked fine with all sound applications: Finder, QuickTime, Safari/Firefox, Skype, iTunes.
I recently upgraded to 10.6 (10.6.4 now) and sound works for all those applications except for sound from a web browser. When video, etc. is playing in the browser, I do not get any sound from the video playback, even though I can get the boops and bleeps when I hit the volume control keys, etc.
Anyone have ideas about what might have changed? (Actually I did notice that the Bluetooth menu item changed from "Use as Audio Device" (in 10.5.8) to "Use as Audio Device (Mono)" in 10.6, but I don't think that should have changed the audio for the web browser.)
Thanks.

Bluetooth stopped working on my ipad mini after ios7 update

Bluetooth stopped working on my ipad mini and my iphone 5 after I updated to ios 7. My Ipad 4 which is not updated can't see them either. Samsung devices can see them but not connect and they can't see each other. Help

Have you tried a reset ? Press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider if it appears), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

My iPhone 5 stopped working with my 2015 Subaru Outback after the iOS 8.1.3 update

My iPhone 5 stopped working with the USB connector on my 2015 Subaru Outback. The phone will still charge, but the message is something like "this iPhone will not work with this accessory". Is there a fix being made? I saw others post with issues with the latest update. It worked fine with the prior iOS version 8.1.2

Hello bballfan85,
It sounds like your getting an error message that the iPhone isn't going to work with your Subaru all of a sudden over USB. I would use these troubleshooting steps from this article, named:
If you need help with iPhone, iPad, or iPod touch accessories
Update your software
Install the latest version of iOS. You can see which version is on your iPhone by going to the About screen.Disconnect and inspect the accessory, then restart your device
Disconnect the accessory and turn it off, if possible.
Inspect the connection between the accessory and device and make sure that no debris or other damage is present.
Restart your iOS device by turning it off, then back on. When the Home screen appears, reconnect the accessory.
Try a different device
Make sure the issue is with the accessory, if possible. Always use an identical or similar, compatible device with the accessory you're troubleshooting.
If there's static coming from the left audio channel when you use headphones, try connecting the headphones to a similar device.
If the device isn't syncing when connected to the dock, connect it directly to the computer using the Apple 30-pin to USB Cable or try another USB port.
If you're using Lightning to 30-pin Adapter in a connection chain, try using the same adapter on a similar or identical device.
Restore iPhone, iPad, or iPod touch
Restore your iOS device. You should rarely need to use this step with an accessory issue. If the issue only affects a third-party accessory, contact the manufacturer before restoring the device.
These steps will help you troubleshoot the iPhone side of the equation.
Thank you for using Apple Support Communities.
All the best,
Sterling

USB Video stopped working with 3.1.8 update

I have been using iChat video with my USB camera for a while with the help of iChatUSBCam. The new update of iChat (3.1.8) included support for USB cameras and once installed my USB camera stopped working with iChat. It just reports the camera is in use by another application. I've been browsing for answers for a while and have tried many things:
- Restart in various combinations of unplugging and plugging in the camera
- Reinstalled the Macam driver
- Reinstalled Quicktime
- Uninstalled iChatUSBCam (since iChat is supposed to work without it now - I think...)
- Reinstalled iChatUSBCam (v 2.2.1 - current)
It's a Logitech Quickcam for Notebooks Deluxe. It continues to work fine with Skype and the the Macam camera tool. I'm using Skype for now (on tour for 6 weeks and use it to video call home) but the quality is crap compared to what iChat used to do.
Thanks for any help you can give.

Some people have reported that Updating iChatUSBCam
and deleting the Macam drivers and then the
com.apple.ichat.plist is the way to go.
Thanks for your help!! I tried these things before, but tried them again in the order you suggested with no success. I'm pretty sure it is not a UVC compliant camera. It's not on Logitech's list of UVC cameras.
M/N: V-UBG35
P/N: 861228-0000
PID: CE6420A
If I try it without the Macam drivers it doesn't show up as a camera is connected at all.
It's so frustrating because it was working great with iChatUSBCam until the recent update. It still works in Skype with no problems, but I'd rather be using iChat if I can - much better video quality.
Thanks for any suggestions!

MBA won't connect to iPhone or Jambox via Bluetooth, but works with bluetooth Apple Mouse

MBA won't connect to iPhone or Jambox via Bluetooth, but works fine with bluetooth Apple Mouse. When trying to pair with the iPhone it says "The Bluetooth Network is unavailable. There was an error connecting to your device. Make sure the device is turned on and in range." When trying to connect to the Jambox it says "Bluetooth audio failed. There was an error connecting to your headset. Make sure it is turned on and in range. The audio portion of the program you were using may have to be restarted." The iPhone and Jambox pair together fine, and I have paired with both the iPhone and the Jambox easily in the past. I haven't updated anything - it just stopped working with these two devices. This is very frustrating.

Bluetooth stopped working on iPhone and iPad

I have an iPhone 4 and an iPad 2, and just yesterday the bluetooth stopped working. I cannot pair the two any longer. It has only come about since upgrading iOS to 5.1.1 anybody out there know the cause and the solution to this problem

I am having a similar problem with my iPhone 4 and bluetooth headset (Plantronics M155). It has always said it was successfully paired with the phone, says its connected everytime I turn it on. However, it never worked at all until I updated the iOS a month ago. However, it just stopped working again. I unpaired and repaired it, successfully so it says. No go.
BTW, my husband has the same headset for his standard flip phone, and it has always worked.
Please, any clues at all? The Verizon store usually says they have never known anyone else with this problem.
Any support would be greatly appreciated.

IPhone 4 stop working with ios 6.1

iPhone 4 stopped working with ios 6.1, visited apple first time, restored phone and worked, less than 24 hours later stopped working again, back to the store, I told iPhone is out of warranty and they'll replace for $150. iPhone worked fine with previous version, no problem at all. Asked to restore to the previous software version, told can't be done. Why should I pay for a damage caused by a software update. Tec claims that ios 6.1 will not work with my phone because it discovered some hardware malfunction, possible the home button. They can't repair. suggested to go to a third party. I'm a satisfied Apple product user for many years. What happened? Any welp out there?

Hey.. I have had this issue since yesterday afternoon.. Some people are saying to keep restoring again and again until it finally goes through.. I have done so like 10 times on my MAC and then I used my husband's PC and tried it 4 times.. No success.. I called apple support, but no help came from there at the end, and the only thing they were able to suggest to me is to sell me a new phone just like mine for a discounted price.. **** NO
Anyways after about 18h of search and stress I came across this link:
http://techglobex.blogspot.com/2012/06/downgrade-from-ios-6-beta-firmware-to.htm l
That will only make it possibe to go backward.. You will end up back with the IOS 5, but at least you will have a working phone and it will bring back all your contacts and everything else that you ever had backed up on icloud and on your computer. There might be descripencies with the Applications but again this is an issue easily solved, you can always download them back.
Two more things: One, you do not have to download the old version of the itunes, the newest version worked for me without any issues
When choosing to download the older IOS 5.1.1, you will need to figure out whether your carrier is GSM or CDMA but you can easily google this info online..
Well hope that will work for you like it did for me

Thunderbolt camera stopped working with Skype and Google Hangouts

Some time ago my built in camera on the thunderbolt stopped working with Skype. If I activate the camera the green light turns on but the screen either remains black or it shows that spinning loading incon forever. The green light stays on indicating the camera is active no matter what I do with skype even if I press the button to deactivate the camera. The green light remains on until you completely kill skype. Rebooting, reinstalling skype, etc. does nothing.
Today I disocvered I have the same thing with Google hangouts. All the way around exactly the same and the green light won't turn off until you kill the web browser. Same thing with FireFox or Safari. Also it no longer works on Viber either.
It's quite infuriating.
I am not sure if this has anything to do with this awful virus like program called "CamTwist" that I installed once and had a very difficult time removing or not.
Reinstalling OS X from scratch is not an option. Too much work, too many programs to reinstall and reconfigure etc.
How can I get my camera back?
The camera works just fine with Photobooth and facetime.
Thanks.

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
The test works on OS X 10.7 ("Lion") and later. I don't recommend running it on older versions of OS X. It will do no harm, but it won't do much good either.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of it have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message. See, for example, this discussion.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. Try to test under conditions that reproduce the problem, as far as possible. For example, if the computer is sometimes, but not always, slow, run the test during a slowdown.
You may have started up in "safe" mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, a series of lines will appear in the Terminal window like this:
[Process started]
        Part 1 of 8 done at … sec
        Part 8 of 8 done at … sec
        The test results are on the Clipboard.
        Please close this window.
[Process completed]
The intervals between parts won't be exactly equal, but they give a rough indication of progress. The total number of parts may be different from what's shown here.
Wait for the final message "Process completed" to appear. If you don't see it within about ten minutes, the test probably won't complete in a reasonable time. In that case, press the key combination control-C or command-period to stop it and go to the next step. You'll have incomplete results, but still something.
12. When the test is complete, or if you stopped it because it was taking too long, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I may not agree with them.
