[Q] Had my GN died?

I was updating some apps in the market, as suddenly the phone reboots without any warnings.
OK, **** happens i thought and let it boot. But now the phone starts the ROMs boot animation for about 4-5 seconds and then reboots over and over again.
I pulled the battery and started into recovery. I made a nandroid and wiped cache and dalvik. Reboot with same behavior.
Recovery again: wiped everything and flashed a new AOKP M3 - result: reboot and loop again
Back to recovery: tried to flash the before made nandroid - MD5 checksum error
Flashed an older nandroid and got boot loops again.
So, i think this piece is for the service now...
What is the best way to reset this GN? Using ToolKit to put back stock recovery and lock the bootloader? Or should i try something else?
Update:
Flashed Stock Google Image via ToolKit 5.4 and after that the phone is booting normal?!?
I reflashed the touch recovery and pushed the AOKP build 27 back to the phone and flashed it.
So far so good - I have to start from the bottom now, because flashing the stock rom wiped the whole phone and EVERYTHING on sdcard is gone
Do you think there is a hardware failure? Perhaps some sort of memory malfunktion or something like that?

Same thing just happened to me, thi is the second time

Firstly when you get bootloops or any other problem do NOT do a nandroid as it backs up EVERYTHING, including the problem.
When you "wiped everything" did you go to mounts and storage and format system, cache and data?
If not then you didn't do a proper full wipe.

This is my own experience, but I want to warn you guys. I had a similar problem with my GNex. The first time it happened, my phone rebooted itself every 5 seconds. I completely restored it using factory image and it ran fine for 3 weeks, then one day, the phone just rebooted itself and got stuck at the boot image. I had to factory reset it again to make it work.
After the second time, I called Samsung and sent it in for repair last week. They are shipping me a replacement unit. It seems the problem was hardware related.

For 3 weeks... exactly 3 weeks, 21 days?
I can tell you that my first boot loop brick was 20 days after I bought the phone. The second was later that day. But the third one was... again, 20 days after the last successful restore. Is there something magical about the 3-week mark???
I am currently taking nightly nandroid backups, so when I had my third boot loop brick my backup was just under a day old. If this is ultimately a hardware problem that can be warrantied, I guess I'll have to try that next time. I would have to make sure I return it with the bootloader locked, stock recovery, but without the wipe because it has to still be boot looping to prove there's an issue!
Anyway, things I will point out:
- It's the complete wipe in bootloader that blanks the internal storage.
- If you have CWM installed, you can back up the internal storage over USB via adb pull /sdcard/ ./sdcard/ (correct me if I got the syntax wrong)
- When the boot loop brick has happened, CWM is not capable of properly reformatting or restoring to the data partition. I have not found a way to repair it without blanking /sdcard (which on the GN is actually in /data/media), so if you don't want to lose those files the only way to keep them is to pipe them out, blank the phone, and then pipe them back in afterwards.
- After a complete wipe in bootloader (either by flashing userdata.img or by relocking/unlocking bootloader), you must boot the phone once into the OS in order to complete the reformatting of /data. If you try booting straight into recovery after a wipe in the bootloader, CWM cannot read or write from that partition.

Can't say for sure whether it's exactly 21 days but it's definitely around 3 weeks. Why don't u give Samsung a call? The phone is not supposed to behave this way. Plenty of people don't have this problem. My wild guess is that the internal flash memory is faulty.

I'll warranty it through my carrier next time as they do exchanges on site. The trouble is, once I've recovered the phone, there's no evidence of the problem anymore. The best way to prove it is to show it fritzing out.

I think this is a known problem. You shouldn't have to prove it to them. They should be aware of it.

It bricked again today so I warrantied it in-store at my carrier. They gave me a brand new one after being unable to find a solution when fiddling with it. As a bonus, all the little hairline scratches on my screen are gone too
The store guy said he's never seen this issue, and it's one of only two warranty locations for my carrier in the Vancouver area. So I can only hope this was a rare hardware problem and not something that pervades every GN they're going to sell.
I can tell this one is from a different batch because it came preloaded with 4.0.2.

Good for you. hopefully my new phone will behave

[Q] CM10 m2 Encryption Issue

Ok. I foolishly enabled encryption on my i711 and after putting in the password, the volumes unlock and the system starts. The problem is that if the screen goes off for any reason, the phone reboots. Tried all sorts of things to correct and decided I no longer wanted the phone encrypted. There is no way back. Ok, so I thought I could do a factory reset... No dice. The phone reboots and all is still encrypted and there.
Next I tried clockworkmod but couldn't do ANYTHING there because the encrypted volumes aren't mountable. I couldn't factory reset, install a new rom, etc.
Next I went to ODIN and tried to repartition. No luck there either. I flashed clockworkmod again for good measure and even tried Nand Erase All.
After this I booted into the phone and tried to repartition... Now I have a phone that displays the lovely CM10 boot screen but never gets passed that. I can still get into recovery.
Any thoughts on how to undo the encryption and reflash a rom?

I have some very bad news for you.... Encryption is a one way street. Once encrypted the only way back is to flash stock via fastboot.
I can't even start to explain how to use fastboot as I have never been in a situation where I have needed it.
recoveries lose all access on encrypted devices so this is the only way.
Here is some links to get you started... Please do research before you begin the process and make sure you've obtained the appropriate files. I will take no responsibility for bricking your device.

Boot Looping Help Please

I purchased a 5x for my wife so she can get on Project Fi. They said it was stuck boot looping, thinking I could solve the problem.
Here are the basics.
-Yes, I can get into boot loader (the menu of start, recovery, etc), but I can't get into TWRP. Tried flashing TWRP a few times and nothing. SkipSoft recognizes that its installed though.
-After bootlooping for awhile, it will load normally and work fine. However it wants to update to the newest version of android. I run the ota and back to bootlooping. It will show the android dude and say "error". Will eventually start bootlooping and then boot normally.
-I have flashed different stock versions. I tried the newest, the second to newest and the last M available. All will flash but continue the bootlooping.
Bootlooping can be anywhere from 1 minute to 10+.
The device will also first display something like, "Your device software can't be checked for corruptions. Please lock the bootloader"
But it'll show up whether the bootloader is locked or not.
The phone will freeze at some point. Whether right away or after 5 minutes. It freezes and then restarts and goes through the bootloop again.
So what else can/should I do? I've never dealt with Kernels but wondering if the last owner did something to them. Is there a way to flash stock kernels just incase or is this done when I flash a Google Factory Stock Image?
Would flashing a non-stock rom be a good idea?
Thanks

So I tried sideloading. I was able to get into the stock recovery. I tried wiping cache and data, then tried installing the newest stock rom.
Everything seemed to work. Then I had to restart. A message popped up after the same "Your device software can't be checked for corruptions. Please lock the bootloader". It had the title in blue stating "Encryption unsuccessful".
Then said, "Encryption was interrupted and can't complete. As a result, the data on your phone is no longer accessible. To resume using your phone you need to perform a factory reset. When you set up your phone after the reset, you'll have an opportunity to restore any data that was backed up to your Google Account."
Then there is a single button that says, "Reset Phone".
Problem still persists.
Help please...

Why did you bought a bootlooped phone?

When my Nexus 5x got into bootloop, I sent it to LG and they had to change the whole circuit. So yeah.

When you flash Google Factory Image, it flash the stock kernel.
If you have warranty, then send it to Google/LG. If you haven't got, then you're in problem. New motherboard needed, but it's expensive.

See the following thread for more info.

What consequences?

Hardware bootloop can't be fix by software.

Exactly. Everyone has either been able to get a replacement under warranty or was pretty much screwed if it was out of warranty.

Stuck on Startup

Having some serious trouble. I rebooted my phone and it asked for my password once it was done as always but this time it said it was wrong. I'm certain I used the correct password but even tried my other alternatives to be sure and still a no go. This isn't the decryption option password you get when booting but my lockscreen password. I booted into recovery and it asks me for an encryption password that I never set but I know this is a common issue with twrp. Tried to go back into android but wouldn't let me because of the "wrong" password so I used the failsafe and went into recoveries file manager and deleted my lockscreen settings to remove my lockscreen passcode (tried and proven method, done it dozen times before). Got past my lockscreen this time but now it was saying starting android forever. Figured it was something with the passcode being deleted so I just decidd to factory reset from the recovery and take that loss. NOW the problem is upon booting the rom in trying to start the setup, I'm stuck on the "just a sec..." screen that comes up after you click start. What do I do from here? I cant access anything in recovery because the encryption passcode issue so I'm kind of stuck. Also I'm a work right now and we cant connect our phones (or any USB for that matter) to the computers and laptops because theyre government property and on a secured line. Any help PLEASE, Ill be home later and can try more then.

Well since you already did a factory reset on the device you mine as well just do a clean install of the OFW then get twrp back and flash your ROM etc back. Would probably be better then to deal with everything going on with the device right now.

Hey, I got my phone back working after that and rooted again and flashed same rom. NOW another problem, I rebooted my phone and its not accepting my PIN anymore, nor my fingerprint, and I cant reset through TWRP because of encryption. WTF is the issue, how do I fix this or do I have to flash-all again?

Weird recovery of a crashed 8 pro.

Popping in to give some feedback as always with my stuff.
Last night while using lucky patcher something must have happened it didn't like because I lost my wallpaper and my call history, at that point I figured she needed a restart. This brought me too a boot that would crash 40 seconds later and boot into whatever it was explaining boot issues
I tried clearing cache in the stock recovery but that didn't help
So I wiped the system settings only
Phone restarted as a fresh phone and is running great! First thing I did was look for and launch majisk, it needed to install some stuff but the damn think came back fully rooted!!!
So if all else fails wipe system in factory recovery.
It saved me a good bit of time unlocking bootloader and all that jazz
Hope it helps someone else when they get to a loop
Merry Christmas all

You can do a full Factory Reset and remain rooted. Since the boot.img is patched and flashed to your device. A full reset wont lock your bootloader too.
Only if you use MSM Tool or relock the bootloader manually (and flash a non rooted boot img beforehand) you relock your device.
