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] Unable to fix bootloop - even tried STOCK flash in fastboot. No luck.

Hey guys,
Long time lurker, ROM user since the Galaxy S days.
Weird, intractable bootloop problem here. Gets to boot animation sometimes gets to the "upgrading android" screen, then bootloops in a few seconds after upgrading a few apps. Usually bootloops during the boot animation (doesn't matter what ROM or Stock ROM I try). Ocassionally gets to my "SIM PIN" screen, then reboots before I have a chance to enter anything.
Normal State have Cyanogenmod and Franco Kernel running buttery smooth. (CM10.1M3 Snapshot + Franco 376 when problem started)
Problem Started When I tried to update CM to the new RC1 from the Cyanogenmod upgrade button in "settings". I had SuperSU installed overtop the built-in superuser. Everything was working fine.
What I have tried:
Have latest CWM: Have flashed, reflashed, wiped and re-wiped everything imaginable through CWM. All Caches, system sdcard, you name it, if it's an option in CWM I have tried formatting or wiping it and reflashing a ROM.
ROMs I have tried - CM10.1M3 Snapshot, CM10.1RC1 CM10.1RC2, ParanoidAndroid 3.5+ (Latest), Bigxie Maguro Latest.
Finally I got fed up and decided to go back to STOCK, unrooted, unlocked using fastboot.
I did:
> fastboot erase boot
> fastboot erase cache
> fastboot erase recovery
> fastboot erase system
> fastboot erase userdata
> fastboot flash bootloader magurobootloader.img
> fastboot reboot-bootloader
> fastboot flash radio radioxxlj1.img
> fastboot reboot-bootloader
> fastboot -w update image-maguro-jdq39.zip
And after booting back into the STOCK google recovery (man I haven't seen that screen in AGES) and resetting factory clearing cache. Low and behold -
STILL BOOT LOOPS!!!! What the hell!?!
I'm at my wits end. Any suggestions would be great. What am I forgetting here?! I am absolutely desperate.

What is in the update image and where did you get it? I'd flash everything manually, skip the update command.

Ok good idea, I'll try. The update image was the stock image from google (can't post link - low post count) I just didn't remember the filenames when I was making the original post - but they are the official STOCK images - for the radio, the bootloader and the ROM.

Okay I tried flashing boot, system, userdata, and recovery manually with fastboot flash and after that I STILL get the rebootloop from google logo to boot animation to google logo. So weird.
Any other ideas?

So decided to try TWRP just to see...well I dunno.
Interstingly enough when I got to hit "reboot" in TWRP it says "OS not installed!!" which is weird because I basically flashed the stock everything 4.2.2 (bootloader recovery, system, boot, everything) from fastboot. Then JUST flashed the TWRP recovery.
I really don't know what to make of this. I just tried keeping the battery out for like 2 minutes, then going back into fastboot and manually flashing:
bootloader
boot
radio
recovery
system
userdata
relocked bootloader
of the STOCK google maguro 4.2.2 (MD5 sum is good. It checked out)
And I still get a continuous reboot loop that doesn't even get past the "X" animation screen. Very ocassionally (1/10) it does get past that screen and I get to the screen where you choose your language, but right when I choose my language, the phone reboots and then continues the loop.
Honestly...Unless someone has another idea, I think I'm going to get another phone tomorrow and pray I'm under warranty. I hate to do it, because I've never had to do that before through all my flashing/ROM adventures...but I don't know what else to do. I've been using sideload for everything (except of course the fastboot flashing back to stock), but I doubt that has anything to do with it...I dunno crap.
anyone have any words of advice?

One thing I thought i might work was redoing the partition table in Odin. So I tried this method:
http://forum.xda-developers.com/showthread.php?t=2065470 (Thanks to Samersh72)
ODIN worked perfectly, download mode worked well, installed fine, and...
still bootloops!
Sometimes gets to "updating android" does a few apps, then bootloops. Once got to the screen where I select language, and before I could select anything - bootloop!
Do you guys think this is hardware? Right now I've installed stock 4.2.2 through ODIN and locked the bootloader in anticipation of returning the phone...

give a try to omap flash

I looked into the OMAP flash method - that's some hardcore stuff. It looks like it's more for phones that can't access recovery, or hard seemingly bootbricked. I can actually do all of those things with my phone - I can write a new recovery no problem, I have fastboot access (Works well), I can even seemingly install ROMs - for instance the cyanogenmod boot animation plays fine - but everything boot loops.
I'm a bit worried to try OMAP Flash because it seems from the thread that some people are having their IMEI numbers erased or set to generic and I don't want that to happen since I'm actually still under warranty right now...
Do you think it's worth it to try?

you tried almost everything.... still on warranty:good:, everything is stock, so what are you waiting for, take it to service center

Yeah you're right. OK done.

While I agree that the safest route is to return the device to warranty, omapflash is a tool which communicates with omap chip before even fastboot/bootloader is installed.
Have you tried viewing logcat/dmesg while device is booting to see why and/or its bootlooping?

I can't seem to get at logcat from this state. even if I try adb -d logcat or something similar it doesn't work. It doesn't pick up the log from the boot. Is it because USB debugging is disabled by default on the stock OS?

Yes, but There's a build.prop property that enables ADB debugging.. Since you have access to a custom recovery, you can mount /system rw and make your changes there.

Similar issue
Hey guys,
I am having a similar issue with my Nexus. It is running Phandroid 3 and one day just locked up, rebooted, and shortly after reboot (15-30 sec. after the OS loads) it freezes. I can still boot into CWM recovery and into fastboot mode, and have tried to flash it with the stock rom and bootloader. I also tried an OMAP flash, but that did not change anything as well. The odd thing is that when I try to flash a new rom (I have tried stock and other custom roms) it flashes as if everything is fine, but when I reboot it still has the phandroid rom on it. Another odd note is that when phandroid boots it notifies me that I have an incoming text message, but I removed the SIM card over a month ago. I have been struggling with this and would love any thoughts or opinions anyone has to offer. Thanks a lot!

[Q] AT&T Galaxy SIII (SGH-I747) will not boot past Samsung logo

I have been using the i747z ROMs for quite some time and after trying a bunch of other ROMs I always reverted back to theirs. So when their 3.0 version came out with Android 4.3 I installed it, using ClockWorkMod recovery. Right after it installed, CWM displayed a message about the boot loader and to fix it. So I went ahead and did that (Don't really remember what the message was) What I know is that I lost root. Also the phone could not connect to the mobile network, only on Wifi. So this morning, I factory reset the phone again, and attempted to root the phone with Odin with CF-Auto-Root-d2att-d2uc-samsungsghi747 (which I had used when I first rooted the phone). Now the phone doesn't boot past the 2nd samsung logo, it starts out with the Samsung logo with the blue circle around it, then the AT&T Rethink Possible and then the plain white Samsung logo. Also, the LED has a slow blue flicker.
I can get the phone into download mode and I have used Odin to attempt to load the stock firmware and the stock bootloader. But after restarting the phone I can't get past the same screen described above.
I am pretty sure this is not related to the i747z v3.0 ROM but rather something a miss with the order in which things need to start in Android. I have done some reading on that but I am not sure what I need to do to correct this soft brick situation. ( I have googled "soft brick" as well)
Any thoughts would be greatly appreciated!

After flashing through odin did you format data?If not try it.
Go into recovery and wipe data.

**SOLVED**
Thanks xXFl4sh, I had tried that.
Solved!
Alright where do I start? How about RTFM Some how I had missed the part about flashing a bootloader and a modem after the ROM. Not recalling having to do that before, I skipped right over it. Once the recovery CWM 6.0.3.1 was finally loaded, getting the flashing the ROM, the bootloader and the modem was easy as usual.
The key was having to use Odin to install a recovery in .tar or .tar.md5 format since I could not access a Recovery Mode on the GS3, as well as a rooted stock image (I used root66_ATT_I747UCDLK3.tar.md5 which is a rooted Android 4.1.1 for AT&T) For the recovery, I couldnt' find a .tar or .tar.md5 for ClockWorkMod (did find a utility to convert it, but didn't want to introduce another variable into the mix) so I used one from Team Win Recovery (v2.6.3.0) and with that I loaded the CWM recovery. Once all of that was in place, I proceed to factory reset, clear data, cache, system and then flash the new ROM, bootloader and modem.
In all of this I learned quite a bit about the whole process and how to narrow down possible resolutions. I still see the "Rom may flash stock recovery on boot" message after flashing either a ROM, bootloader or modem, but just backing out without answering Yes or No seems to work. Also (and this may be related, I don't see the option to restart in recovery from shutdown menu). Don't really know what that's all about for now, and honestly don't want to mess around (at least for a while)
I know the steps are general, but I hope this can help some else if they get their devices in a soft brick situation. As for the i747z v3 ROM with 4.3, I really like it, everything works (Wifi,Blutooth,tethering) and the battery seems good as well.
Thanks!

[Q] Nexus 7 stuck at Google logo and can't unlock bootloader

Hi all
Interesting issue that I've searched here and Google for and not getting far, my searching skills may not be the best though as I'm fairly new to this.
My Nexus 7 was working fine, put it on the side, came back and it's turned off. Thinking it's flat I charge it and try to boot it with no success. Pressing the power for a while does get it to turn on but it gets as far as the Google logo and stays there.
I've factory reset it in the recovery and nothing
I've tried to flash the stock image from Google but when unlocking the bootloader it just sticks on "yes" forever and nothing happens.
What can I do at this point?
Cheers

Have you heard of Wugfresh Tool kit ? (aka Nexus Tool Kit) It is in the development section or you can google it. It is quite famous.
It will do anything actually from drivers to repair a device stuck on google logo. Just make sure you select the correct option.
You will need unlocked bootloader to flash stock images. And to do either of those, you will need drivers!
Install drivers and use it to recover your device. If you still have trouble, quote me back and I will help you to my best of ability.
Look into the forum before posting your questions. There are so many similar problems and you can easily find a solution by reading their questions and their possible solution.
Good Luck!

I'm having issues with my nexus 7 (2013). It will not boot up,it's stuck on Google logo. I am able to put in fastboot mode. I'd like to do a hard reset/wipe but I cannot enter recovery mode; it just goes to the Google logo and doesn't show me the recovery menu. I thought I could try doing it through adb but bootloader is locked. Downloaded WugFresh toolkit but it requires correct build number, which I do not know. I tried different ones but everything fails. AND USB debugging is not enabled, but I cannot do it through my tablet because it won't pass bootloop. I haven't been able to enable it remotely. So, any help with getting this tablet up and awake?! It's not rooted BTW, its running stock 6.0 marshmallow

Interesting, and troubling for you, I'm sure.
-- What do you mean, in fastboot it doesn't show you the recovery menu? If you are into (more properly) bootloader mode, the Recovery option has to be there. Do you mean you just can't select it, or that it won't work when you do select it?
-- Using fastboot, you might be able to boot into custom recovery without flashing it. (e.g. "fastboot boot twrp.img", not "fastboot flash recovery twrp.img".
-- Have you tried unlocking the bootloader via fastboot? Is it possible OEM Unlock is already/still enabled somehow?
-- Also.... Wug's NRT doesn't need the correct verion/build. The last option in the drop-down menu on the NRT is this: << Android *.*.* - Any Build >>
HTH

-- When i go into bootloader/fastboot mode, the option is there for recovery mode along with 'start' and 'power off',etc.. However, when I select it,it just hangs on Google logo and never shows me the Android man and recovery options.
-- Sorry, not sure what you mean by this: "Using fastboot, you might be able to boot into custom recovery without flashing it. (e.g. "fastboot boot twrp.img", not "fastboot flash recovery twrp.img"."
I may need some instructions on how to do this please.
-- I have tried unlocking bootloader via WugFresh and Nexus toolkit and via adb but it hangs on erasing user data and also hangs on 'unlock bootloader's screen (left it for over 12 hrs). I doubt anything is unlocked.
--Yes, I tried the "any build" option and nothing works.
Thank you
I'm open to any suggestions.

Ah, right. I didn't read closely, and didn't realize you might not have used fastboot tools... and please, I'm no expert, so if I'm saying somthing inaccurate, I very much hope someone will correct me.
I'm never sure how much a poster knows, so I'm not sure if you meant you don't know fastboot commands at all, or just the specific ones I mentioned .. fastboot commands are like ADB commands, but run in the bootloader environment. We know you have fastboot commands installed and fastboot drivers installed on your computer because you have adb installed - which includes fastboot, and you said WugFresh's tool was able to run, which means you also have the right fastboot drivers (the NRT uses the same fastboot commands).
fastboot can be used to flash/install custom recovery packages, among a whole lot of other things. So what I mentioned in that command was a possible way to maybe get into a custom recovery if you have to do things like wipes or whatever, even if you can't actually fully install the custom recovery. You might need to do this stuff, if you can't unlock your bootloader and flash the whole official Google Factory Image from their website (which is what I'd try - simple instructions are right there, too).
Flashing the full factory image will wipe your device, of course, but there are simple ways around that, which you can find on this very forum. Good luck.
Let us know how you get on.

Custom binary blocked by FRP.

My friend's J2 Prime (SM-G532G/DS) happened to be stucked at Security Error (blue screen), no idea how it get there. Tried to flash stock firmware. But after flashing, the phone booted back into the same blue screen, now with a line of red text at the top saying, "Custom binary blocked by FRP. (recovery. img)". Tried many different stock firmware (with 4 files) but none of them solved the problem. Can't boot into recovery, only download mode. Can someone give me detailed step by step on how to fixed this.
If it help, I'm from Malaysia. So maybe the firmware might need to be from this region. Not sure about the origin of the phone though. Also, what could be the reason for this to happen? I'm assuming root. Could it even happen on its own, I mean without rooting or flashing?

also G532G/DS - ARH1 bootloader
i've been going thru lots of ROMs (including testing Lineages), this have never happened to me before.
Flashing stock firmware thru Odin though, require OEM Unlocking ON in Developer Settings.
^ I mean, did you/your friend turn it on before flashing? if not, it actually succeeded?
Only solution might be possible:
Go to stock recovery (POWER + HOME + VOL-UP), wait for it to load, then factory reset from there.
I suppose some images might help!

I'm pretty sure the OEM if off because he know nothing about this thing. When I got it, it already like this. Can't get into recovery, after the first Samsung logo appear, it went straight into the error screen. Same thing happened after flashing.
I don't know how to post images here...

+ OEM Unlock: if disabled, Odin should've failed straight away and no reboot stuff going.
+ Can't get into recovery:
Is it true that you cannot get into recovery? If left stock, It should be an Android with spinning stuff, text is "installing update" then no command for a while ~2min, and it will go to normal recovery.
I mean, it is supposed to do "recovery" :v
+ Images: post it on Imgur (or any online image service). Copy link here, add space between "https://" and all the stuff there. Wont be considered URL i guess (havent tried)
