[Q] Crashing on Bootloader / Display Tear

OK so I've looked through the forum (admittedly the Galaxy Nexus specific one only) and tried some searches but may not be able to articulate this problem in clear way. Basically, I'm continuously crashing - started with a stock, but unlocked/rooted install. Now it won't boot and crashes in the boot loader as well after a few seconds (thus not allowing any non-trivial actions to actually complete.)
The first crash was after enabling face unlock for the first time. When I hit the power button to shut things off, the display "tore" and then went totally dark. Phone was completely unresponsive till I pulled the battery for a few minutes (found that one from search.) Couldn't complete a boot sequence though - would go to the animation, then display would go wonky and then shut down. Would usually have to pull battery again to get any response from that.
Went to recovery mode and wiped data - which completed - same problem on boot. Only thing I'd done was unlock and root (for eventual root apps, none of which had been run) so decided to undo that (using "Galaxy Nexus Root Toolkit 1.3.") On the factory restore there are several steps (boot loader, radio, etc.) and I haven't been able to complete that process.
I suspect it might even be bad hardware at this point, but can't go back to VZW with the phone still showing unlocked. Phone is a recent eBay purchase to replace a lost device but seemed fine for the 2-3 days I used before this all started.
Anyone seen something like this before?

So your able to get into recovery still? If it doesn't boot into the os it's probably a compatibility error between the kernel and rom your using (Just clearning data in recovery won't fix this).
So what rom/kernel combination were you using at the time?
Also have you tried flashing a completely different custom rom to the one your having issues with.
And any nandroid backups you have made in the past?

What's weird is that I was in stock kernel / rom at the time. (At least I'm nearly sure - it did come from eBay after all...)
I'll also try changing the ROM, that could be it. The big question is if that can complete before the thing melts. If I boot to recovery and wait, doing nothing, the system crashes in a minute or two.
My current thinking is that I might have a bad recovery / clockwork mod install.

can you still get to the bootloader and is it stable to sit on the bootloader?

I can get to the boot loader but it is not stable there (I think I was conflating the two.)

does your bootloader look like this? i want to make sure you and i are talking about the same thing.

Yep, that's the one (before it crashes. I have a pic of the amusing video display when it does that I'll put up when I hit the magic 8 posts...)

try using ODIN to restore your phone. instructions are found here: http://forum.xda-developers.com/showthread.php?t=1394051
also, how long can you sit on the bootloader before it crashes?

I'll try that as tonight - thanks!
Varies on time to crash, but no less than 30 seconds and no more than 5 minutes so far. Requires a battery pull and wait to come back after that.

i would like to see the picture of the crash you are talking about.
also, you can relock the bootloader real fast before you take it to VZW. only takes 1 command once you get to the bootloader
fastboot oem lock

Wow, same crash while in download mode. That can't be good...

yeah thats not good at all. i'd lock the bootloader and return it

http://dulinor.smugmug.com/photos/i-XkKWCrg/0/S/i-XkKWCrg-S.jpg
This is the crash I'm seeing

Yeah return to the store and show them this, the board is probably bad.

thats rough, but since you got it on ebay returning it may be a hassle and if the phone is not a north american model samsung might not even accept it for warranty.
did you try to flash the stock google image using fastboot instead of using the toolkit? it will only take a few mins. when you display crash like that does it still take commands from fastboot? you can test it when the display crash like that type in fastboot devices and see if you get the id number in command prompt. if your build was yakju then you can get the factory images from here http://code.google.com/android/nexus/images.html

Just got back from the store - they issued a replacement, none on hand so one should ship out today. (Thanks for the tip on re-locking it - not sure if they checked, but was happier having that.)
So of course, it actually completed booting (for the first time) but crashed during activation. Once they saw it crash on the Odin screen, they were happy to do the swap.
I had been trying to re-flash OEM Google - which it should have been all along.
Thanks everybody for your help.

Stock HTC One (M8) in boot lock - please help

Hi,
I'm looking for some help with my currently unusable HTC One M8 on EE in the UK. I have done no rooting or making my phone S-OFF to date (and don't have the appetite for it if I'm honest) but it is now stuck in a boot loop and I don't know how to fix it.
On Monday, I accepted an OTA update which seemed to go fine but the reboot then triggered off an update to HTC Lock Screen App. This requested permission to reboot the phone and since then, the phone has been in a constant boot loop. I have tried various options including going into the menu system and selecting 'Recovery' and 'Factory Reset'. None of these options appear to do anything as the screen blanks for a moment and comes back up with the HTC initial screen and then goes into its loop. What does seem odd is that when I go into the recovery area, the menu system is unresponsive to the volume buttons until a series of code lines come up (IMAG1838.jpg)
{
"lightbox_close": "Close",
"lightbox_next": "Next",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
which takes some time to cycle through. Once completed, I can then select things like 'FASTBOOT' (IMAG1840.jpg) . Picture IMAG1839.jpg is the only screen I see if i try and reboot/recover anything. I don't know if it means anything to anyone but I also took a pic of the 'IMAGE CRC' (IMAG1841.jpg) .
Can anyone help me resolve this without rooting or voiding my warranty? EE suggested speaking to HTC as they didn't have any ideas or they could send my phone away for repair. This is an option but would rather resolve myself (with help!) if I can.
Although I'm reasonably clued up on general operations of phones, the bare bones of software is a different planet so any assistance will need to be in baby steps and spoon fed (sorry).
Hope the pictures are ok? If not, I can type out the various messages.
Thanks in advance.
Phil

did you Factory Reset while at fastboot mode?

Hi,
Yes - I did try a factory reset but this didn't resolve the problem and it literally rebooted immediately without appearing to do anything.
Thanks

Try powering down, then holding power up+power for 20 seconds. This is the equivalent of a battery pull.
Might work, might not. Give it a shot.
Then report back. I/someone might come up with a different solution if it doesn't work for you.

Hi, it was a good idea - but unfortunately this hasn't resolved the problem. Sounds like it's going away for repair unless any other forum users have a stroke of inspiration. It does feel like something has overwritten or corrupted the bootup code somehow!! At least it doesn't feel like anything I've done so warranty is still in place
Thanks for your help.

Rooted Elephone P8000 stucks at Boot Logo after OTA Update

Hi there,
The phone is rooted.
I've proceeded with the latest update today (~12mb size), don't remember the exact version.
It said it fixes some system bugs, etc.
After the update installed the phone won't load, stucks on the changing color logo.
Cannot access the recovery mode option in the boot menu (Vol+Power), says "no command", if press and hold Vol+ and Power again the phone restarts and enter the boot logo again.
Has anyone ideas how this can be fixed?

See http://forum.xda-developers.com/elephone-p8000/help/boot-loop-ota-upgrade-t3246203.
Post #16 describes how get into recovery from the 'no command' screen, and my post #12 describes how I managed to get it flashed using the SP Flashtool.
(Note my point no,5 - all I needed to do is press 'Download' first, THEN attach the powered off phone.)
Good luck!

Actually, what you need to do is format the data partition or write the empty data.img file over the data partition which in effect does the same thing. And the later one is also what happens when your download entire rom using sp flash.

In that case you probably need to flash the system.img and maybe even the boot.img from the latest rom. Elephone really should stop sending out these broken OTAs...

You belive this b***** that feed you on official forum? OTA should work on any device software config.

I didn't read official forum. However you do loose your warranty if device is rooted, thus the device manufacturer owes you nothing. OTA worked fine before I rooted my device.
Btw, I got my phone back to life by re-flashing the entire ROM, just in case.

The only thing you need to do is reinstall the añl the system with spflashtool. Never and remember never you can update any android with a ota if you are a rooted user.
If you speak spanish you can search in the youtube channel AndroidMxL to ser how you can reinstall the original ROM on your android.

Relocking was a bad idea, you just ran out of all options.
I'm not sure if there is any way around enabling OEM unlocking.
Try the previous suggestion.

Snapdragons are truly unbrickable. But I'm not sure I know enough to help.

I'm fairly sure fastboot boot <image> doesn't even work if the bootloader is unlocked on the op3.
Also, it looks like recovery did get flashed.
Try rebooting to recovery?
Power off by holding power button, then hold vol down + power.
Then if you are booted into stock recovery, just side load the stock ROM.

This has happened to me too. What I did was that after several attempts I managed to get into twrp and reboot the phone into fastboot via twrp. I know it sounds logical, but try to connect the phone to the computer and hold the power off button and click the volume up button several times. Try it several times, it always works. Via Orange Fox, reboot the phone into fastboot and install the stock rom when you are in fastboot mode. I hope it helps you.. good luck
