Lenovo A6000 keeps rebooting after upgrading to Kraft-A6000_S029_150212

I just updated my new Lenovo A6000 smartphone to Kraft-A6000_S029_150212 version. Since then, it is continuously rebooting. It comes up, stays for 5 seconds, UI hangs and then reboots.Need urgent help on how to recover.With great difficulty, was able to switch off the phone as it wasn't giving me enough time to power off. The continuous booting up sound was irritating people sitting nearby and I wasn't even able to turn off that sound.

Will check with service centre and update here. FYI - I had received the phone on 13-Feb-2015 and as soon as i switched it on, it prompted for a software upgrade. So I upgraded (over WiFi) with whatever was the latest software version available at that time. After that upgrade also, the phone used to automatically reboot atleast 3-4 times a day randomly. I thought that could be a bug in that version and to take care of that, I upgraded to the latest version this morning only to end up in constant reboot mode. So not sure if this could be a manufacturing defect too. Thanks.

Desktop/Finder keeps rebooting after upgraded to Maverick (mac mini hooked up to a home theater system)

My desktop keeps rebooting ever since I upgraded to Mavericks.
Current setup, Mac Mini hooked up to home theater (Panasonic SC-HTB20) that is then hooked up to my Panasonic Plasma TV.
I usually leave my Mac Mini on running and at least once a day when I turn on the TV I can see that my desktop was rebooted. Firefox and Chrome will say that it wasn't shut down properly and if I want to restore my previous session. Also some times when I switched the input to watch TV and switch back, all my windows will be scattered out of place. For example Chrome will be in the top left hand corner to the point that it's almost minimized and I wouldn't be able to move it as well. Only thing I can do is close out these applications and relaunch them. It doesn't appear that the OS actually crashed, but more like the desktop/finder itself crashed. Cause once in a while I will switch back or turn on the TV and the screen will stay black for a few minutes then I'll see the cursor in the top right hand corner. After that I will start to see the desktop and my application start loading. It doesn't go through the regular process of rebooting where you see the Apple logo so I don't think the OS actually crashed but I could be wrong.
For some reason it seems like Maverick doesn't like the home theater system. An almost guarantee way to reproduce the issue is to wait for the home theater to turn off after it's been inactive for a while. If I turn it on the home theater to have the audio coming from it I will see the desktop goes black immediately then the whole desktop reboot process I mentioned above will kick in.
Never had any of these issues on 10.7 before I upgraded to Maverick.
Anybody have any suggestion? I really don't want to format and downgrade back to 10.7.
Thanks

Sounds like a kernel panic.
If you post the report we could have a go at deciphering it.
It would be in /Library/Logs/Diagnostic Reports.

Mac keeps rebooting after upgrading to Mavericks from Snow Leopard

My iPhone 4 can not reboot after upgrading to iOS 6; keeps trying and cannot shut off either.

My iPhone 4 can not reboot after upgrading to iOS 6; keeps trying and cannot shut off either.

I FINALLY got it to work on BOTH iPhone 4 and iPpad 3. Here is what I had to do:
Had to DELETE all e-mail accounts including icloud.
Did a hard reset (hold down button on top right corner and round button on bottom center)
Then once it came back on, the iPhone had ALL of the accounts still on it and it was receivng e-mail.
The iPad receive e-mail until I did the steps above 5 times. Plus, I had to add back all of the e-mail accounts vs. on the iPhone 4 they were there when my phone came on.
Now I am receiving e-mail on both devices normally.
No clue why this happened, but Apple needs to find a fix ASAP.

My iPhone 4s keeps restrating after upgrading to iOS 7.1.2 and comes up with recovery mode.

My iPhone 4s keeps restrating after upgrading to iOS 7.1.2. I tried to restore for few times using iTunes and installed only 8 apps freshly from iTunes apps store. After restating the phone goes to recover mode every time. Last time it came up with a diagnostic massage with a big apple logo saying..'we are hanging there'. I am really frustrated with Apple coz my last mobile 3GS's network circuit was so poor that I could not use that to make call. However can any one help me with my iPhone 4s problem? I've no warranty left that's why I think apple will not help me any ways.

Try changing the channel on your router to manually select & use,the highest number channel available. After I did that I no longer had the problem.

Multiple crashes, blue screen, reboots after upgrading to ios 7.1

Hi All.
My iphone 5s 32gb worked perfectly fine until upgraded to ios 7.1.
Now it keeps crashing, rebooting multiple times a day. Sometimes it enters in a rebooting loop.
I´ve tried reseting, restoring, downloading the upgrade and restoring again and again but the problem persists. Very frustrating.
I´ve enter to diagnostics and usage data on mi iphone and there are at leat 100 crash reports.
What should I? Whait for ios 8? Forget Apple products for good?
Thanks.

Thanks for your advice! I don´t live in the US. I can see there are a lot of people having the same issue after upgrading to ios 7.1. Is it possible that my iphone just got broken? I repeat that after the upgrade it worked perfectly fine.
Kind regards.

Lenovo X240 keeps rebooting with Kernel-Power (Event ID:41); Windows 7 Professional

Hi All
I have my newly Lenovo x240 installed with Windows 7. Sometime, it can boot up, but sometimes it keep rebooting during the windows logo appear.
When it goes wrong, it will have the following screen.
But, if I am lucky, after several "auto-reboot", I can get into the Windows 7. But sometimes, it shows the similar screen above (without windows logo but with what my current desktop), and it then auto reboots.
This scenario is so random, I don't know how to fix it. At this stage, I don't want to use system restore, as some software is installed by my client which is not located near my office, while the reboot issue happens before those installation
Here are some event 41 details that I captured.

Could you please help?

Jacky

Hi JackyCheung,
I would strongly you to ensure you have the latest drivers and also Windows Updates installed before proceeding with anything else. Have you ran the diagnostics to see if anything hardware related maybe causing the issue?
In this scenario I highly doubt System Restore would help, was it working OK when you got it? what has changed since it was working without the issue?

10.5.2 Feature causes machine to shutdown upon reboot after upgrade.

After upgrading to 10.5.2, the machine reboots, then after
a lengthy spinny gear on the up swing, it promptly turns itself off. Boot up several
times, same result. Boot into single user mode, run fsck, after clearing
the boot disk, fsck gives me an error of some non existent drive. New in 10.5.2:
"the computer will now shut down if an automatic disk repair does not succeed during startup."
Turns out i had an old entry in the /etc/fstab file ... silly me.
Anyway just passin that one on for all other forgetful folks.
-miles

OK,
I at least got the repair to work and it said there were no problems. I remember when I was waiting for the reboot after the 10.5.2 install that the fans went all crazy in my iMac and then settled down. I remember an issue a while back where this happened and it was because of the SMU... or System Management Unit. In older Macs it is called the PMU (Power Management Unit) so do a search for that if SMU doesn't bring anything up.
Resetting this usually resolves power related issues.
http://docs.info.apple.com/article.html?artnum=301733
The above link describes how to do it on the iMac G5... you may need to do a search in Apple Support for your particular Mac. Be sure to use the search field on the left of the screen, not in the Apple.com navigation bar at the top right.
Did you also try resetting your PRAM? You do that by restarting (or starting) the Mac. Press and hold CommandOption+PR all at the same time. Keep them held down until the computer restarts again. I just did this (and still haven't reset my SMU) and the Mac has not shutdown on me yet.
If it does start to shutdown randomly again I will reset the SMU and let you know how it goes.
Good Luck!!
Jon

Continuously rebooting after upgrade to 7.5.1.a

Hi everybody
After upgrading our SPA phones to 7.5.1.a firmware, we're having problems with bmp logos.
With a SPA303, if you put the logo address in the provisioning file...
<BMP_Picture_Download_URL>tftp://192.168.1.100/logo.bmp</BMP_Picture_Download_URL>
... after making reset to default parameters, and let the phone load provisioning parameters, it starts rebooting again, and again, and again... If you remove this parameter, everything goes well.
If you monitor the tftp server (tail -f /var/log/daemon.log), you'll see the phone reboots just after request the logo file.
With a SPA504G happens the same if I configure the logo file in the web interface. Phone starts rebooting continuosly.
We've had to remove the logos, because it seems something's broken in this new release.
Does anybody have the same problem?
Regards
Alberto

I've just tested it with new firmware 7.5.2b and the problem persists.
Nelson, about the workaround...
- If you put the logo in the web interface, the phone doesn't reboot. But after that change, if you reboot the phone electrically, it starts rebooting again.
- It's not only with a brand new unit. It happens always after doing a Factory Reset and let the phone provisioning again.
I've tested it with a SPA504G and a SPA303, and both has the problem. They work OK with firmware 7.4.9.
I've also tested it with HTTP provisioning, and happens the same.
So at the moment I don't have a valid workaround, except removing the logo from provisioning . Without logo, it works ok. Anyway, loading the logo using web interface it's not option if you have many phones...
Nelson, you already have my files, and it keeps failing ALWAYS to me. I think this is a big problem, because logo it's something that clients really appreciate and because the phone turns unusable.
Let me know how can I help you...

Bluetooth Mighty Mouse keeps freezing after upgrading to Leopard

My bluetooth mighty mouse has frequent, intermittent freezes (which appear to be a loss of sync to the iMac) after upgrading to Leopard (now 10.5.1) from 10.4.11 on my iMac 24" alum body. This mouse was rock solid on my iMac running Tiger. Luckily I do have a corded mouse which I've been forced to use the past week or so.
Can anyone suggest anything?
Thanks.

I was just trying to help my Dad with the same exact issue (Mighty Mouse stops working on waking from sleep & trying to open bluetooth prefs at that point causes the system to lock up. Have to hold down power button to reboot)
Oddly I have Leopard on my iMac 2.16 Core 2 Duo and have no issues with my Mighty Mouse.
Hopefully someone comes up with an answer .... My Dad is 80 and just bought a new Powerbook and Mighty Mouse. It's hard to explain why the mouse doesn't work.

Apps keep crashing after upgrade to ios 7 ipad2

After upgrading to ios 7 most of my apps keep crashing on ipad2 why? Do i need to re-install them? Please help

i am having the same experience (as well as several other problems) since installing iOS7 on my iPad2. The apps briefly appear to open when I tap their icons, but then disappear. double tapping the Home key to bring up the multi-tasking view idicates that the apps are running in the background but, I cannot access them.
This fiasco began because I was unable to login to my One-to-One account after the iOS7 update. I spent 4 hrs on the phone last night, with 4 different people from Apple support, restoring the iPad to factory settings & then restoring the image from my iCloud backup, only to end up with the situation described above. And I still can't login to my One-to-One account, plus I amnow also unable to access the iTunes store. I am sure there are other problems that I have yet to discover.
This has been such a "Windows" experience that I find myself wondering if Apple truly has lost its mojo & mystique. Are their pretty products worth their premium prices? More importantly, are they worth the frustration I experience, & the time that lost from my life, in trying to resolve problems with their"improvements". If asked today, my answer would be a very loud & resounding "NO"!!!!!
