IOs 5 Update sent iPhone 4 into infinite reboot loop!

I see that many people are having issues with the update not working, but I haven't come across someone with the issue I have.
I tried to update to iOs 5, but it forced my phone into recovery mode. After trying to restore it to factory setting several times, receiving multiple errors, my iPhone 4 is now stuck in an infinite loop of showing the startup screen (apple logo) then the spinning circle. It cannot be reset, and it is not detected by itunes. I tried all of the suggestions on the pages the errors linked me to, but nothing worked.
I have no idea what to do...
Suggestions?

Well, lots of people are saying that Apple is the new Windows. There are, unfortunately, right.
As Apple keeps growing, the problems on my Mac and iPhone keep growing, too.
My iPhone 4 is in an Infinite Loop, rebooting the whole time.
After 7 hours (!!!!) of attempts, I finally found this solution: keep the power and home button pushed in, then release the power button and only keep the home button pushed in. Then you can update (if Apple lets you, my iPhone is still restoring after more than 1 hour).
This is really a shame and very bad publicity for Apple. Last year Antennagate, now Upgate, what's next?

Update Sent iPhone into Recovery Mode

A friend told me about the update so I connected my iPhone to my computer and chose "Update." I got an error that ended with my phone in "Recovery Mode." iTunes recognizes it as an iPhone in recovery mode and I choose "Restore" but what seems to be most of the way through the restore I get an error saying (direct quote) "The iPhone "iPhone" could not be restored. An unknown error occurred (6)." After I first had problems I updated iTunes, but that didn't help. I'm on hold with phone support. I've yet to talk to anyone.

I also experienced the "recovery mode" issue. After distilling some of the recent posts here and related topics, here's what I found worked for me. (1) Delete iTunes 7.6 update, download and install iTunes 7.6 from Apple's website. (Good idea to back up your iTunes library just in case). (2) If you have tried several restores of the iPhone without success, navigate to //user/library and delete the several backup files there. (3) Reset your iPhone (simultaneously press home and power key until Apple logo appears). Turn iPhone off (press power key until screen blanks). (4) Plug in your iPhone and you'll hopefully see that the software and firmware is being restored. (This takes a while). After that, you'll see the message that your iPhone files are being restored, however you have them set in iTunes. One note -- though I'm not sure why, having your iPhone plugged directly into your machine's USB port rather than through a hub may prevent device polling from corrupting the iPhone restore process. This worked for me -- not sure if similar process would work on Windows boxes or not. After about an hour of messing with it, now have updated iPhone fully functional (again) with new features.

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.

MSI z77a-G45 Infinite Reboot Loop

Hello,
Here are my system specs:
Core i5 3570K
Hyper212 Plus
Intel 330 180 GB SSD (with OS on it)
WD 1TB Black (for data)
MSI z77a-G45 motherboard
G.Skill Ripjaws 8 GB RAM
EVGA GTX 660 FTW Signature 2
Corsair TX650m PSU
Lite-on iHAS124-04 Optical DVD Drive
Corsair 200R case
I should mention the following up front: I don't know what is causing my problem, but my guess is it's either PSU or motherboard.
Nothing in my system is overclocked (except for the fact that my GTX 660 card comes factory OC'd). Here is my issue. Yesterday, I shut down my computer and everything was normal. I didn't change anything at all. Today in the evening, I tried to power on my computer, and it simply goes into an infinite reboot loop. I don't see anything on the monitor, nothing comes up. The computer powers on for about 10 seconds, and then powers off for about 5-6 seconds, and it keeps repeating this process. Actually getting this process to stop is a bit tricky (I think I have to hold down the power button for several seconds when the computer is off). Does anyone have any ideas? I've tried a few things, like checking to make sure the 8 pin and 24 pin cables are tight. I've tried resetting CMOS and taking out the CMOS battery. Ideas? Thank you.

Hi guys. I know this thread is 2 and a half months old but I need to find a solution to this problem. It may have been better to start a new thread, excuse me for not doing it as my problem is quite similar.
Well, my situation is a bit different and I will explain it shortly but first I'll give you my PC specs.
MSI Z77A-G45
Intel i5-3570
Corsair DDR3 8GB (2x4)Kit 1600MHz Vengeance
Nvidia GeForce 9800GT
So when I assembled my PC I put one RAM in DIMM2 and the other in DIMM4. This led to an infinite reboot loop. The fans and the leds were working but nothing was displayed on the screen. After doing some tests removing and inserting again the RAMs with different combinations I came to the conclusion that this infinite reboot loop is occurring when a RAM is inserted either in DIMM1 or DIMM2. My PC works fine if I connect the RAMs in DIMM3 and DIMM4 but not with the DIMM1-DIMM3, DIMM1-DIMM4, DIMM2-DIMM3, DIMM2-DIMM4 combinations.
At first I thought one of my RAMs might be corrupt but after the tests I see that both work fine and I'm starting to believe that the Motherboard has the problem.
Any ideas? This is really frustrating.

Random iPhone crashes and reboot loop after iOS 7 upgrade

Hi all
Since I upgraded my iPhone to iOS 7, I suffer from random crashes/resets, where my iPhone reboots and enters a reboot loop (Apple logo, black screen, reboot, Apple logo, black screen, reboot, etc) that I can only exit by restoring the device (resetting doesn't help).
Some more information
a) The device: iPhone 4, 32 GB, has never been jailbroken, and has never shown any similar issues before.
b) The crashes/reboots: I haven't been able yet to find a pattern when and why they happen. I had reboots when searching for an app, when pluging in the wall charger, when entering the access code, and even when doing nothing at all (iPhone in my pocket). The only constant is the reboot loop after the crash.
c) What I tried so far: I restored the device several times, using normal restore (with the iTunes logo) and DFU mode (black screen). After that, I recovered from a recent backup (takes some hours), and everything is ok again - for some hours, until the next crash and reboot loop. I also set up the device as a new phone, and there it seems stable, so I exclude a hardware issue. I tried quite a few of the advices that I found when googling for reboot loops: reset all settings (this led to an another immediate crash and reboot loop), disable app background refresh, etc.
I've been using this device for my daily business. With the current instability (and the couple of hours it takes to bring it back to life again), it became more or less useless. I wish I could downgrade again (I know that I can't). My assumption is that either iOS 7, or some incompatible app or some corrupt setting is causing this situation. But I don't know how to proceed to isolate and eliminate the issue. I really would like to avoid setting up everything from scratch again.
Any advice is greatly appreciated!

All,
First of all, sorry for my half-finished post above. While typing, I was interrupted, and by reflex I hit CMD-S. Unfortunately, the stupid interface of Apple's support website interpreted that as a submit command. I tried to complete my text with the update function, but when finally hitting the submit button, I got an error message, and all my updated text was gone... No way to bring it back, and also no way to delete the half-baked posting. Quite frustrating.
Now, to complete what I started above:
In my case, the problem definitely had something to do with the springboard process (an iOS system 'app' that manages the iOS homescreens) and the watchdog process (another iOS system 'app' that monitors certain things on your phone and that can initiate a restart when it thinks the phone is frozen). In the folder '/Users/<your account>/Library/Logs/CrashReporter/MobileDevice/<your phone>' I could see what caused my crashes; they were all 'stack+SpringBoard' and the reason in these crash log files was 'Watchdog timeout'.
The following two forum posts helped me:
https://discussions.apple.com/thread/1676330?start=30&tstart=0
https://discussions.apple.com/message/20794982#20794982
I'm quite sure that my issues had to do with the 'application map' that is mentioned in the above posts. So far, Ive been thinking that it was just too large (as in the case of Andi1996 [second link above]), but jmbladen's observation seems not to support this. So, the absolute number might not the source of the problem, but I still assume that something went wrong with my application map during the upgrade from iOS6 to iOS7. I remember having stability problems before, as soon as all my 10 home screens were full of apps and newly downloaded apps would generate additional pages (only visible via iTunes). Considering that there are some fundamental changes to how we can organize apps within folders in iOS 7, it can well be that the springboard process just wasn't able to cope with my application map correctly within the 120 seconds before the watchdog process restarts the phone. My massive cleanup action must have fixed this somehow.
@jmbladen: I'm only using iCloud for the 'find my phone' functionality, so all the backup & recovery was done via iTunes from my local harddisk. And there was no temporal pattern for my crashes before. You might suffer from the same symptoms, but probably not because of the same cause.
My advice for anyone affected by random crashes and a reboot loop is to check out the directory with the CrashReporter logs mentioned above to find out what app or process causes the crash. If it's the springboard and watchdog problem, then you should try to clean up your home screens (from iTunes). Maybe the absolute number of apps is not that important, but make sure that you reduce the number of screens. And then sync and backup before you start using the phone again. In my case it helped.
Hope this helps someone else too.
P.S. Once you know the right keywords to search for, you find forum postings back to 2008 / iOS 2 describing exactly the same problem. This reboot loop is a very nasty issue, and it is hard to understand that Apple still hasn't been able to address this, or at least provide some better help on how to get out of it again.

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.

OVM3 Guest PXE Boot goes into infinite install loop

Hello Avi,
When I create a PVM guest, using OVM Manager 3.0.3, within the network path I pass something similar to the following:
--args="ksdevice=eth0 network ks=http://<your_KS_server>/<path>/ks.cfg" http://<my_iso_server>/mounted_isos/OL5/
This works just fine, the VM pops up it finds the ks.cfg and does the install. However, on the reboot it goes right back to this PXE install and continues to do this in an infinite loop. I tried changing the bootloader from /usr/bin/xenpvboot to /usr/bin/pygrub, but if I do that it just gives Error: Boot Loader didn't return any data!. I also tried removing the bootargs and leaving it as bootargs='' and that also didn't work, same error.
Obviously the continuous rebooting into PXE and reinstalling is a bug, but how can I fix the vm.cfg file manually?
Thanks,
Roger

NOTE: This is for a PVM Guest.
ok, I solved my own problem but it's ugly.
Due to the infinite rebooting into the pxe installer, once the installer is done, I had to make sure on the reboot I turned it off before it goes back to the PXE. Once done I had to make modifications to the current vm.cfg. These are the parameters that you must modify:
bootloader = '/usr/bin/xenpvboot'
boot = 'n'
bootargs = ''--args="ksdevice=eth0 network ks=http://<your_KS_server>/<path>/ks.cfg" http://<my_iso_server>/mounted_isos/OL5/
Comment out the above and modify the bootloader line on the vm.cfg as follows:
bootloader = '/usr/bin/pygrub'
Side NOTE: Make sure your ks.cfg file installs kernel-xen and subtract kernel (-kernel) within your ks.cfg. Otherwise by default it will try and boot into the non xen kernel for a PVM and you get an invalid kernel error similar to this Error: (2, 'Invalid kernel', 'xc_dom_parse_elf_kernel: ELF image has no shstrtab\n')
Hope that helps someone out,
Roger

TS2529 iOS update throws phone into recovery mode - HELP

The current iOS update seems to have thrown the phone into recovery mode now requiring restoration through iTunes. Of course I don't have photo stream on and fear losing all my photos. Any way around this?

Reset, hold both the home and power buttons until the iPhone begins to restart. If this works great. If not you may have to Restore the iPhone to get it working again. If you decide to do this you may even have to use DFU Mode to Restore. Here are the steps for DFU. Open iTunes on computer. Connect iPhone to computer with USB cable. Hold both Home and Power button, after exactly 10 seconds release the Power Button, keep holding the Home button until iTunes recognizes iPhone in Recovery Mode, usually about 20 seconds time. If the iPhone screen is black, blank this is DFU Mode. Click the Restore button of iTunes.
