Desperate Help Needed!

So I am the proud owner of a shiny, new Galaxy Nexus (GSM). Unlocked the bootloader and installed CWM recovery and was doing great. Today I decided to install the volume fix. Installed the zip through recovery, completed and rebooted. The phone got stuck in a bootloop over and over and over and over and would not boot Android at all. Did a ton of research here and everywhere and, in a panic, I booted into CWM recovery, reset the cache & did a full factory reset. NOW, the phone will not go past the Google bootscreen with the unlock symbol, no matter what I do. AND, I can't even flash the original google image because I can't get in to set USB debugging so my computer won't even recognize the phone (FYI, I'm on a Mac). I am at a complete loss and don't know what to do. If I could only get the computer to recognize the phone I could flash the original google image through Terminal, but alas, I can't. Any ideas? If I can somehow get this phone back up and running I would be eternally grateful. For now, I think I may be SOL. Thanks....

This happened to me, I was not able to solve the issue, even though I could push and pull data to and from the device via ADB. I could still not get past the google logo. I decided to lock the boot loader again and return to the store for a new device.

Galaxy Nexus stuck on Google logo boot loop help [GSM]

I am running the stock rom without root and unlock and I got the 4.0.2 OTA update 3 days ago. Today when I do the pattern unlock my phone froze and reboot. Now I cannot get pass the Google logo boot screen.
I am able to get into the recovery mode but I don't want to do a factory restore as I don't have anything backup yet.
Is there any solution to this boot loop problem? I am surprise that I am getting this problem as I am running the stock rom without any root / mod.
If there is no solution to this, is there any way I can backup my phone before doing the factory restore?
Many thanks!

You can back up via adb. Try searching in the General threads, since there's a long topic on this...
Good luck!

Thanks, I do find information about backup, but I can't find anything regarding the bootloop...

When i got stuck at the Google screen with a bootloop i booted into the bootloader/fastboot screen with vol up+down power and i redid the one click all process and it basically rewiped my device and put it back to working again with unlocked bootloader rooted etc....
All you have to remember is what build number you have and let the toolkit work its magic.

Sorry, forgot to mention. You're probably gonna have to wipe via recovery - which is why I pointed you to a back up...

I can't find a way to backup without going into Android. I can only go to Fastboot Mode.
Anyone know how to backup the file using abd without getting into android?

Why did make 2 threads about this. Unlock the boot loader and use adb to flash your stock. Image files. You will loose all data unfortunately but I think that's the only way to fix it.

Ok I'm stuck with the same problem now. I wanted to flash a ROM, so I downloaded AOKP, flashed it and rebooted and the phone refuses to boot past the Google logo and keeps rebooting again and again. I am able to get into the recovery. I have flashed the ROM several times and its still the same. I have done a complete wipe as well. Still no go.
Fastboot command doesnt work in the bootloader either. I have made sure the drivers are installed, still there is nothing when I type fastboot devices. If I type any fastboot command it just says <waiting for device> or something like that.
Any other suggestions? :-s

[Q] Help! - Rooted Zenfone 2 (ZE551ML) bricked after OTA accidently

followed a tutorial (Cnncted's youtube clip - How to root the ASUS ZenFone 2 ) to root
Accidentally (very stupid) pressed the update option when an OTA update showed up yesterday (Jul 8 2015), and after that the phone won't start properly - stopped at in search of incredible...
No luck with trying to boot into recovery mode (power + volume up). It just vibrates once and the screen is black. Trying to flash recovery image with ADB and flashtool etc, but the MTP usb connection failed. If I connect it to the PC using the USB cable and then press the power button to turn it on (stuck in that ..."incredible" screen), device manager shows the Z200AD name with a yellow exclamation mark beside, and Asus ZenUI software will automatically start. But it's not really recognized by the PC.
So...if you have any suggestions for me to try, please let me know and that would be greatly appreciated!

p.s. This is a US version, so the it's the WW sku?

Same problem here. I have a rooted 551ML and on July 6th I received an OTA update. I installed it and I'm stuck in boot loop. I have hundreds of family pictures in the internal memory.
The good news is that I have access to boot loader and recovery.
I could not find any custom recovery for Zenfone 2. They are not out yet, right? Is there any way to copy the internal memory of the phone (that doesnt load the OS) to the SD card? Or to paste a file img.boot taken from a downloaded official rom and copy it over the corrupted one on the phone's memory?

If you can access the bootloader, you can do this:
http://forum.xda-developers.com/zenfone2/general/guide-to-apply-ota-bootloop-rooted-zf2-t3127835
Btw, there is a custom recovery out there (TWRP, check the Development section), but you will need an unlocked bootloader to use it in your state (I think).
US version is the WW SKU btw. Hope this helps.

Joel, thanks a lot! I will give it a try.
fingers and toes crossed...

I faced this problem too. All I did was to flash the boot.img of my version using fastboot,
Then I flashed the firmware, without factory reset I started the phone.
I was continiously getting an error "com.android.process has stopped". Ignoring that, I just backed up my whole data. Did a factory reset. Updated
Boom!! Everything was normal... I hope this helps

Just a quick update - followed the method in the link that Joel referred to, and everything worked beautifully. I did get two error messages like “the contact stopped working..." “The process android.process.acore has stopped working.” I fixed this problem by clearing the data/cache from the "contact" app, and that did the trick without a factory reset etc.
I unrooted the device using SuperSU. The fastboot screen, however, still shows a random serial number 0123456789ABCDEF. Is there a way to revert it back to the real one? I do see the real one from settings - about - status.

Isn't everyone serial number the same? mine is.

This is something that I am not sure of. Yours has been rooted as well?
I would like to know what the fastboot screen looks like before rooting.

Pretty sure rooting didn't affect my fastboot screen at all.

actually i rooted my zenfone 2 and there was an OTA and i tried to install it without un-rooting my phone. the phone would not turn on and it gets stuck in the boot animation.
the phone wasn't detected by the ADB in my pc so i thought of installing some custom recovery, thought that could help.
i tried installing TWRP but i did not unlock the bootloader and now i am not able to enter in recovery mode either, everytime i try to get in the recovery modethe phone restarts and goes to fastboot mode.
please help.

I was having a similar issue where adb wouldn't recognize my phone but fastboot was detecting it. What I ended up doing was grabbing the latest stock firmware zip from asus, transferring it to my external sd card via adapter and renamed it to MOFD_SDUPDATE.zip. Then go into fastboot (restart with volume up key) and proceed to recovery. It should automatically update your system from there. The only bummer is having to re-configure everything.

Android 11 Beta 2 Stuck! HELP

Hey! Need a little help. I updated to Android 11 Beta 2. Now my phone is stuck on a boot loop. A li'l different though, phone boots up normally and stays on the lockscreen and alive. Can receive calls. But once I unlock with the pattern it shows ' Phone is starting' works for a good 2 seconds and then ends up on infinite bootloop until I Power down. How do I access my files on PC ? If I can get just few files out of it then maybe I can perform a factory reset . Please HELP!

some older app is causing the loop you mayneed to factory reset through recovery or flash factory images to ur devices ,( please backup your all data and i will advice you to remove the screen lock if possible as it may cause issues after flashing older or newer images

That's what I am asking. How do I backup?

I use this tool in my computer to update my phone.
Make sure to follow and read the instructions.
Since you're phone is in boot loop, put your phone in into bootloader

Facing the same trouble, did it help?

Hi, I finally managed to solve this!! Was able to get the phone working with data intact.
So I got exactly the same problem yesterday and was looking around for a solution when I bumped on this thread, the solution suggested to use Android Flash Tool can work only if the bootloader is already unlocked, USB debugging is on and you edit the flash.bat file to remove -w from the command line, which would not work in my case since my bootloader is locked and unlocking through ADB would wipe all data
So the only good solution is to do an OTA UPDATE USING ADB SIDELOAD, I just downloaded the OTA file, connected the phone to computer, booted into recovery and used ADB to sideload the OTA and boom, the phone is its pristine self again, with ALL DATA intact

Question Stock on loading screen factory locked - Bricked - can any data be saved at this point?

Hey folx, you seem to be my only hope!
My stock Android factory locked Moto got out of sudden into a loading screen loop. I learned it got bricked without me even trying to anything at all to the phone. Problem is that I cannot do a factory reset as there is lot of important unbacked up data. Unfortunately USB debugging is disabled and I cannot even load up recovery mode. The only place I can go to is fastboot, but I cannot use ADB.
Is there any slightest chance my data can still be saved somehow? Tried Googling up all day, but would not find a solution to the problem. Have no idea that a stock android phone can generate a load loop. I am pretty desperate. Please help!
Thanks
Six

I have a similar problem. Did you find a fix or solution? Please share, I'm pretty desparate too

I'm in the same boat, I used orange fox's bootloader by accident, switched slots and now Im stuck on the fallback bootloader

Guys even I have the same problem I can't even boot into fastboot or recovery mode. Oh and USB Debugging is off and Bootloader is Locked. Pls help
