Y70 Touch Reboot Loop

I run a Y70 Touch model with Windows 8.1.When I log on with my Windows Account (the only user registered on the system) I move onto the Start screen. However, after a few seconds the system simply reboots and I need to log in again.This does not happen all the time - which confuses me. When it happens, the only way I found to log in successfully is to shut the laptop down, wait a while, and then start it up and log in again. This let's me gain access to the system, but the problem remains.Any advice out there?Thank you kindly.

Len,Tx. I tried the auto repair and ran it abt 4 times. Everytime it told me that nothing wrong was found.I then tried to boot up from start, but the reboot loop problem remained.In desperation I then I reset the system with all the hassles that come with such a drastic option. I personalised all again and the system ran fine - the problem did not appear.Last night as I shut down the computer it done the normal thing when it wants to update, so I let that run and it shut down by itself after the auto updates were done.This moring the problem has returned. I again ran the auto repair which told me nothing was wrong and no repairs done. I then moved from the safe boot to log in - successfully.But the reboot problem is back. I am not sure whether it is a Windows or a 3rd party Lenova software problem. And I really do not want to reset the computer and lose all my personalised setup again as it is a schlep and did not solve the problem before.I (though I am ignorant on software) suspect that the problem comes after some auto update as I explained above. I recall I had an auto update before the problem appeared in the first instance as well. I am not sure if it is Windows or Lenovo updates.I must admit that it drives me nuts - more so as I am not a software specialist.Any advice to resolve this will be appreciated.Thanks in advance.Since you have identified that the problem occurs right after an update I think it would be proper to perform a restore. Do the Windows restore operation and not the OneKey Recovery one. It should put you back to the condition before the update. Once you are in that condition, you can do a manual update. Do the update one by one so that you can isolate which of them is causing the problem. Once identified do the restore again and this time ignore the particular update.

IPod touch 4g 6.1.6 stuck in reboot loop after trying to restore

My ipod touch 4g has a really bad battery and only works if you have it plugged in and charging, but I've never had this problem before. I unplugged it from where it was charging and it died, of course. But when I plugged it into my computer to sync it, it started an endless reboot loop with the apple logo. I tried putting it into dfu mode and restoring it, I've tried doing it on three other macs, and the I've let the battery drain since it dies when I unplug it. Still dont know what the problem is. I cant take it to apple cause I dont have apple care on it and they cant help because the battery doesnt work anyway. Help is much appriciated.

See if y misse anything here:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order. You do not need AppleCare and it is free.

IPhone stuck in reboot loop - too many apps installed?

Hi guys!
Starting some months ago, I've had nothing but problems with my iPhone. However, I've been dealing with most of these or even solved them.
But now I'm stuck on a reboot loop for a few days and don't know what to do.
When did it start? I think it was in May when I first got panic.plist, ResetCounter and SpringBoard-CrashLogs under "Diagnostics and Usage". Following this, everytime I rebooted my phone or the battery was empty, it could take some more minutes than normal for my iPhone to boot. This loading time increased and increased, in October it once took more than two days for my iPhone to reboot. I now have really thousands of those ErrorLogs. The Apple support on the phone couldn't help me either. Additionally, the phone performed some cruel changes I can't explain: Once the language was changed, once the photo gallery had to be restored (the iPhone did that on its own).
However, sometime in November the iPhone crashed, and I was already thinking that it would now last a few days until I could use it again. But somehow it was done within 15 minutes. Without any error or reboot loop. The last two months I haven't had any problems with this until the battery was empty three days ago.
Since then, I have had the iPhone plugged in so the battery doesn't get empty and it's stuck on the bright Apple logo. After about 210 seconds the logo gets dark, then the screen is completely black and it's starting the same procedure again. Sometimes I get the vibration, sometimes the loading circle (white wheel of death!), but everytime it just starts over again.
I am pretty sure this problem appears because I have more than 1300 apps installed (yes, this is a very huge number, but I remember Steve Jobs saying that, with the folders in iOS 4, it would be possible to have a few thousand apps installed), 4000+ photos, and so on. I am pretty sure it's not a hardware, but a software problem. In detail, it's about the SpringBoard. The iPhone 4S only has 512MB RAM, so it's hard for it to load 1300+ app icons into its memory (which it has to because the SpringBoard has to run without any lags). Only in some cases it's able to boot that up, but I have absolutely no idea which cases these are and why it has run well for the last two months, but beginning with the new year stopped to work.
Furthermore, the panic.plist entries all say that the problem is a watchdog timeout. Apple's iOS seems to allow the devices only to take up to two minutes (always around 120 seconds in the CrashLogs) to boot up, then probably another 120 seconds to launch the SpringBoard process (which explains the watchdog timeouts in the SpringBoard-CrashLogs).
I will not restore the iPhone because I unfortunately haven't backed up for a long time and there have been many data changes since the last backup.
So altogether, I tried to collect all the information I know here, but that's really not enough. Apple unlikely wants to help me, the phone support was really nice, but even asked his superior, who couldn't help either.
My questions to you folks now are: Do you have any more information regarding panic.plist's, watchdog timeouts or reboot loops?
What would your advice be? Any chance to get onto my data and back it up? Or is waiting the best solution?
Would it be better to try several hard resets, or let the battery run empty and start the whole process again, or just let the phone plugged in so it tries to reboot on and on until it's hopefully successful sometime?
And: Would it maybe increase the loading time if I would take the SIM card out of the iPhone, so the chance to have an successful try would be higher?
Note: I am still using iOS 5.1.1 because I am completely sure that I'd have to buy an iPhone 5 to run 1300+ apps on iOS 6.

Okay, some more information about this.
Apparently there is a 'watchdog' that listens whether the iPhone's software responds or not. If it doesn't, it forces a restart, and also creates a panic.plist entry (under Diagnostics). Unfortunately the responding time is only 120 seconds. The problem I have now is the so called 'Application Map'. To ensure a smooth browsing through the different screen filled with apps, this map is regenerated everytime the user installs a new app or deletes one. Because I have more than 1300 apps installed, generating this Application Map usually takes more than two minutes. I can only hope that sometime in the next days my iPhone will be able to do this in less than 120 seconds (like it has done that several times before).
I still can't explain why everything had been working great during the last two months. I have probably installed some new apps, but also deleted other ones, so the number of total apps didn't really increase heavily.
However, I've read about some possible solutions to this problem (without restoring - which would solve the problem only temporarily anyway):
Hard-resetting the iPhone until the screen is completely black, then wait a few minutes, then turn the device on. It's possible that this has to be repeated several times, but for the user who posted this it resolved the issue.
For all the (in this case lucky) guys with a jailbreak: SSH into the iPhone, then temporarily move the watchdog located under /System/Library/SystemConfiguration/mobilewatchdog.bundle to a different folder, the iPhone will boot up after a few minutes. Then just move the watchdog back. It's a shame that apparently jailbreak users can resolve this issue, while normal users can't.
I also want to note that this problem has been appearing since iOS 2, which came out more than four years ago. It would be really no big deal for Apple developers to change the 120 seconds to e.g. 300 or even more. I've found hundreds of threads, not only here, where users complain about exactly the same issue. I don't have any hope that an Apple employee will ever read this, but if so, please keep that in mind. I don't understand why Apple has done nothing to solve this issue.
However, if you have any more ideas, please reply here. If there's anyone around here who has managed to successfully install more than 1300 apps on his iPhone (or iPod touch), please post that.

Intel iMac stuck in reboot loop

Since the last few days, my 6 month old Intel iMac is stuck in a reboot loop.
Configuration:
Model Name:          iMac
Model Identifier:          iMac12,1
Processor Name:          Intel Core i5
Processor Speed:          2.5 GHz
Number of Processors:          1
Total Number of Cores:          4
OS: 10.6.8 (with patches applied as they become avaliable)
It is connected to a UPS at all times.
I always put it to sleep at night. Sometimes it stays in the Sleep mode for a couple of days (i travel and wife does not use for some time). But it always would "wake" up from Sleep on a keyboard touch. Magic mouse battery died a few days ago, so put in a new pair of battery, had the usual problem of "pairing", fixed that and continued on.
(Coincidentally, it almost also marks where my problems started).
Now, when i press any key, the iMac reboots. And then just before it looks like it will show the wallpaper, it reboots. and this continues on - sometimes 10-15 times. I press the power key and switch it OFF. Press the power key again, no go - stuck in the reboot loop. Run the Apple Hardware Test (exhaustive one included - it reports no issue found). Do a SMC reset (take off the power cord from the back of the iMac for 35 seconds) and put it back. Switch off the mouse and attach a USB mouse and press the Shift key to boot into the Safe mode. This works! Installed Pacifist to check for any non-Apple kernel extensions, none found...
Since AHT reports all fine - can hardware be ruled out?
Could it be the magic mouse? Need to try it (just wary of the reboot loop )?
If it is the mouse, is it covered in the 12 month initial warranty (I am in India)?

Any/all help is appreciated. I am going to carry it in to an Apple Care tomorrow, but was curious to see what the community had to say.
Thanks,

Well, it is getting odder now...when i read your message and click the console icon on the dock, the iMac just crashed and rebooted!

Reboot Loop Question--1Gen

It appears that my kids 1Gen Touch has encountered a reboot loop. The on/off/Power button appears to no longer work. When pushed, nothing happens. The home button functions fine.
When pushed with the home button, the device enters a rapidly cycling reboot loop. Apple logo for 5-10 seconds...off for 5-10 seconds...apple logo...repeat. This can be interrupted by plugging the device into a power source (wall/computer). When the device boots up (after being connected) it appears to work fine. Once it gets plugged in, it boots up normally.
As soon as it finished booting up (after being interrupted) the red "swipe to turn off" bar comes across the top. Hitting "cancel" will cause it to go away. After booting up, if left alone, it will sleep without entering the reboot loop.
While it is functioning, the home button with wake it up. If the on/off/power button is pressed to wake it up, it will enter the reboot loop.
Is this a hardware or software problem. I will next try to restore it, but wanted to see if there was some guidance before I did that.
Itunes does recognize it. I have backed it up and it seems to run ok after breaking the loop and not hitting the on/off/power button. If left alone, it will spontaneously enter the reboot loop (5 minutes or so).
Thanks,
Chris

Hi to all,
I have a big problem with my Xperia Z3, I updated it lollipop 5.0.2 couple of days ago. It worked fine with no issue until yesterday (Saturday 04.04.2015) when I left it in my car for the gym session as always. When I came back to check missed calls, I couldn’t access the phone at all, only a black screen and I could see a clock and partial notification bar. I switched it off and the on again.
Now its stuck at” Android upgrading, starting apps” all the time and it keeps restarting. I have tried to soft –reset nothing is happening. I have reached at a level to lose everything in the phone especially my contacts by deciding to do a hard/factory reset but still I cant do that using volume up or down. I am totally stuck, I also tried to boot into recovery mode but with no luck.
Please guys any idea how to get rid of this. I cant get into recovery mode coz nothing is happening when I press key combination.
I will appreciate your help. At this point I regret why I updated my phone to lollipop.
Please help help………

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode

- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Strange reboot loop

I have an iPod Touch 4th Generation, running iOS 5.1.1. Today, an update for an app (specifically, the Clash of Clans Christmas Update) came out. I updated it and tried to run the app. It crashed immediately every time I opened it. So I decided to try a reboot. Now, I'm stuck in a reboot loop. It shows the apple logo, and right before it finishes the reboot the strange flashes white and then restarts the process. The device is completely unrecognized by iTunes. About once every 20 reboots (it's been hapenning that long...) it gives me the Blue Screen of Death (lol Microsoft terms ). If I hard reboot, it just goes straight into the loop again. I've tried iReb to take it out, but not even that works. Is my phone bricked or is there a way to fix it?

P67A-G43 B3: Cannot POST--reboot loop on formerly working system--out of ideas

So I bought a computer today off of Craigslist. I demoed it before buying, running CPU and GPU benchmarks and playing a bit of Skyrim. Everything looked good. I put it in my car, drive for 10 minutes (no big bumps/turns to speak of) get it into my apartment, plug it all in and *BOOM* the computer starts for a sec and then powers down, going into a loop, doing it over and over till I hit reset. 6 hours later, I have made no progress, hoping someone here might have some suggestions.
Specs:
P67A-G43 B3 board
i5 2500k CPU
16gb GSkill DDR3 1600 Ram (2x8 gb)
Geforce gtx 480 video
Corsair 650W PSU
What I've already done:
First, I re-seated ram and video. Same issue.
Then, I tried re-seating the motherboard, took it out and screwed it back in (thinking something came loose and caused a short). No dice.
Next, I tried resetting CMOS (unplug power, hit "reset CMOS" button, took battery out for 5-10 mins, replaced). The computer boots! But, no video. No harddrive access. No nothing, other than the fans, as far as I can tell. I restart, and it's back to square one (with the infinity reboot loop). This behavior is repeatable, IE if I reset CMOS, it gets it out of the loop for one start, but there are no other changes. It doesn't constantly restart, but it's not giving me anything more than that, and the restart behavior returns as soon as I power off. In fact, if I short the Power On switch on the board to turn the power off, the system comes back on about 2 seconds later with an infinite loop. Strange.
Then, I took everything out of the box, re-assembled on a breadboard with bare minimum components. With CPU and No RAM, the behavior is the same (including the reset CMOS behavior). Ditto if I add a stick of RAM (tried it with both sticks, in a bunch of different slots, no difference) and if I add the video card in.
Additionally, I've re-seated the CPU heatsink, no effect. I've checked the pins on the CPU for any bent pins--I saw none, everything looked normal as far as I could tell. On the back, all pins look good, except for two that seemed to be touching on one of the PCI slots (this PCI slot does appear slightly bent forward on the front). I took a knife and carefully made the pins not touch, like the rest of the slots, but this seems to have had no effect.
So, I've got what should be a pretty sweet rig sitting on a cutting board right now unable to do anything. I consider myself reasonably technical, but I'm out of ideas. One thought I did have was I wondered if there was any way to upgrade BIOS with the board in such a state? Maybe by USB? Doesn't seem like I can though. Also, this system was working fine TODAY, and apparently had been working fine for a while, so wth, why now? Anyway, any help would be greatly appreciated, I'm tearing my hair out.
One additional note: the green tag on the motherboard w/ BIOS description says "E7673\IMS1A0"
Many thanks!

Since it was working fine before it got into the car and within 10 mins there's problems. I think it could be some of the power connections to the board or the PSU suddenly gone bonkers.
The reason for pointing out these two hardware is due to the fact that they have not been changed out with another similar hardware for testing yet.

HT6114 Reboot loop after 10.9.2 upgrade

My 2009 (dual-quad) Mac Pro 4,1 is now stuck in a reboot loop after upgrading from 10.9.1 to 10.9.2.
//edit: I realized there wasn't a question: What is wrong with my computer and how do I fix it?
So far I have tried:
* Repairing the disk
* Repairing permissions
* Zapping the NVRAM/PRAM
* Resetting SMC
* Copying BootCache.playlist from a backup to /var/db
Other things to note about my setup:
In addition to the original hard drive, I installed a 4tb drive from which I have been working with since June. It is the 4tb drive that has 10.9.2 installed. The original 650gb still has 10.8.4 installed and all my original data pre-June.
Also installed is a VisionTek Radeon 7870 video card which powers my numerous monitors. I do not recall having to install anything extra, or modify any settings to get it to work. The only downside is you can't really see anything when booting.
In addition to the VisionTek card I also have one of the factory Geforce 120 cards installed. Using another monitor attached to that card I've been able to monitor the boot process using the command-v verbose output.
Of notable interest I get the dreaded "BootCache: unable to open /var/db/BootCache.playlist : 2" error, along with a few SMC errors. If these are important I can attach pictures taken of the boot process.
I am able to zap the NVRAM and boot the old 10.8.4 650gb drive. It loads fine. 10.9.2 will not boot into safe mode, but will boot into recovery mode.
As a final attempt to fix the BootCache error I copied it from a Time Machine backup into /var/db/ ensuring the correct permissions were set. After rebooting the file is deleted again.
I would greatly appreciate any help on this issue as this is my work computer. I do have full backups via Time Machine so I can reinstall, but I'm hoping there's another solution.

I just started a discussiion related to this topic in "Mac Pro."
https://discussions.apple.com/message/25019730#25019730
" I have a 2009 dual quad core Mac Pro (4.1) with an upgraded Radeon 7950 GPU. I use a 30" Apple Cinema display (DVI) and a 27" LED Cinema Display (Display Port). After updating to 10.9.2, the Mac would not boot, but went on a continuous re-boot cycle every 5-10 minutes without a flicker of life in either display. I unplugged both displays and the Mac booted. I could log in remotely from my laptop. I then attached the 30" Cinema Display into the DVI port and the Mac booted normally."

I was told by itunes my phone needed an update to 6.1.2. I did it, and now my phone is stuck in a reboot loop, and no wifi, phone, or bluetooth.

I connected my 3gs to my computer, and got a popup from itunes saying there was an update for my phone. Well i like to keep everything up to date, so I did the update. After it completed, I no longer have phone, Wifi, and bluetooth. It also is stuck in a reboot loop. I really do not know what I can do. I tried to restore it as a new phone, since i had all my data backed up.
Any help or ideas is greatly appreciated.

okay i may have called it wrong, we got the unlock from AT&T when our contract was up. We did this because we were thinking of switching to another carrier.
I checked the hosts file, and there is nothing refering to gs.apple.com. Should there be?
Is it possible to restore it back to 6.1?
No problem; it's just that many people buy what they think are "factory unlocked" phones, but the "factory" is the back room of the shop where they bought it.
gs.apple.com should not be in the hosts file (the only reason it might be there is if some hacking tool had been used on the computer in the past; not just jailbreaking tools, but tools to downgrade the OS and perform other unsupported functions).
You cannot restore back to 6.1; you need to resolve the problem with the latest version. Even if you could revert it would not solve the problem. You need to figure out why iTunes can't communicate with the activation servers. If you have another computer, try restoring on that, or take the phone to an Apple store and let a "genius" deal with it. Or, if your antivirus is Kaspersky, delete it completely, as it's impossible to turn it off completely, and it has taken a dislike to things Apple.

Power button not working - reboot loop

Bought a new iPhone 5S last week, activated it and used it 2-3 hours. It had iOS 7.0.4. I updated to 7.0.6 and everything is working for 2-3 hours again.
Now the power button is just no more working. I reset the configuration back to default and the phone is now in a reboot loop. It is not shutting down correctly, it shows this small animated circle. I cannot turn it off or bring it to the DFU mode because the power button is not working.
iTunes cannot find the iPhone when I connect it - I guess because it is already in a undefined status.
What can I do to fix it? It seems to be a hardware / physical problem because I can hear the normal sound when I click the power button.
I guess I need to return it to an apple store ?!

I waited until the battery was empty; the phone was empty now, I charged it via Macbook and after 5 minutes it started automatically again without problems. Now I made a reset via iTunes and will change it in the Apple Store. It is working perfect now from point of stability, speed, configuration, functions - only the power button does just not react in ayn case.

PRS-T1 stuck in infinite reboot loop after failed firmware update

Hi,
I tried to update the firmware, but failed when updating to version 1.0.07.05070. Tried to 2 times. The first time it failed I simply tried again. The second time, it took a lot longer to reach the failed to update message, but it did cause the ereader to reboot.
Now, it's stuck in an infinite reboot loop on the "Opening book" page. The progress bar on that page stays completely empty, lasts for about 30 seconds, and reboots again. This will go one until the battery is dead or indefinitely if plugged in.
I have tried pressing the Home + Menu buttons, but they seem to have no effect.
Please advise if there is anything I can try to revive it?
Thanks in advanced.
David
Solved!
Go to Solution.

Kiroken,
Here is what I have observed:
- After a hard boot (reset + power button during 3+ seconds), if I don't do anything, it will reboot every ~30seconds.
- If I press and hold the Home and Menu buttons, no effect. The same as if I didn't press anything.
- If I press the Forward + Back buttons (2 & 4), it does not reboot after 30 seconds. Instead, the orange light on the power button blink every ~2-3 seconds.
- Any other key combinations that I have tried have no effect.
I have tried with and without several rescue sdcard. No difference. No improvement. In every case, the computer never sees the reader. If plugged into the power outlet, it seems like the battery charges alright. It does not appear to charge if plugged into USB port.
That's all I know. If I can't fix it, I might be forced to turn it into a coaster or maybe a cutting board for the kitchen.

HELP!!! MBA will not boot. It's in a constant "reboot loop!"

Hi! I was having issues with my MBA and it's well known problem with getting a bit hot and shutting down the core etc. One post mentioned coolbook. Several peole gave it the thumbs up so I decided to give it a try. Installed it and was asked to restart. Now my MBA is in a constant reboot loop and will not start-up. it gets as far as the gray screen with the Apple logo and the spinning wheel. Then about a minute or so later it reboots. And this goes on and on forever. The MBA is now insanely hot and I have turned the MBA off not to cause any damage.
I can not boot in safe mode.
Any ideas??
Thanks!!

thanks for the views, but seems nobody wanted to help. cheers for that!
i managed to reboot using the OS X DVD and reinstalling. Now I have an eject symbol in my system bar top right corner and my superdrive will not "eject". this means I can not use the USB for anything else. meanwhile I ejected the OS X DVD from the drive and tried to reinsert it. NADA.
Getting to the point where I am fed up with the MBA. It gets so hot I could fry an egg on it. The system must be running something in the background, becasue even with a new install it still is slow and stutters (and no, I did not start you tube!) either this is from a real crappy batch, or I looked at it the wrong way.
Looks like I am heading back to the MBpro.
