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

Bricked my Oneplus 3

Okay so I'm new to all this rooting and stuff and I was messing around with TWRP and now my when I turn on my OP3, it shows "md5 checksum failed" with "cache:failed", "system: failed", "system_aging:failed" and goes into a bootloop. And I cant even boot it to recovery mode. It's driving me crazy!

Can you still boot into fastboot? Turn on with volume up, if so reflash TWRP, and then restore your backup, or flash a stock rom.

I can boot it into fasboot and I tried flashing TWRP, OxygenOs and even Cyanogenmod. Still didnt work.

Didn't work how, are you getting errors in console?. Can you flash TWRP and boot into it?

You have successfully bricked your device.
Don't worry use a Oneplus download tool to download stock firmware to your device in download mode.
https://forums.oneplus.net/threads/guide-mega-unbrick-guide-for-a-hard-bricked-oneplus-3.452634/
The method 2 worked fine for me.
Go ahead..!!
Hope it helps

A bricked device is broken unable to be fixed, this is a soft brick as you can still get it to respond.
For future users if you broke something and want help please supply at least the following.
1. What you did, yes it's embarrassing but maybe someone can undo it.
2. What you are still able to do, can you access recovery, fastboot or adb.
3. What you've tried, if you try and flash something and get an error message let us know.
The more information you supply the better the chances someone can help. A simple my device is bricked help can't achieve much.

So I'm telling now how I got to this situation:
I'd installed a rooted OxygenOS with TWRP. I don't know how I thought it was a good idea to lock the bootloader after I installed TWRP, still did it. After that I was able to load in to fastboot, nothing else. Followed Method 1 on the link from Joyo-rocker and came to the posters message. Now I'm trying Method 2. Will update this post.
Edit: If your phone shows the boot messages "md5 checksum failed" with "cache:failed", "system: failed", "system_aging:failed" you need to fully reload your ROM over the unbrick tool. Look for Method 2 in Joyo-rockers link in this post (cant post links yet)

Go to the folder where the recovery tool.exe is. Boot your phone into Fastboot.
Search for cache.img, system.img, system_aging.img and put them in your ADB file folder
Type this:
Fastboot devices > doesn't show up? No worries I'll help you later this day just let me now.
Fastboot flash system system.img
Fastboot flash system_aging.img
Fastboot flash cache cache.img
If it boots and you don't have Sim and WiFi. Then reflash Oxygen OS and don't boot it! Boot it into Fastboot and type:
fastboot erase modemst1
fastboot erase modemst2
Now boot it and u can do whatever you want!

Why would you install windows instead fix the driver thing.

Was having problems with uninstalling the drivers. They would always come back so only way I could do it was by a reinstall of windows.

This was already mentioned, as i remember. Just let me search for a minute cause i had this same issue.

You see.. OOS had force encryption. Go to Fastboot and type "fastboot erase userdata" then go to recovery and flash OOS or any other rom.. Password should be gone now.

Help, might have killed my device

Not 100% sure of best place to post this, but I'm getting desperate now...
I'm pretty worried I've killed my device. After following the guide on how to root with Magisk, my phone is stuck on the white "loading" screen with a G logo. I've since tried to restart, but I can either go into fastboot mode or get the white screen when attempting to boot into android.
Tried to flash the latest factory image to fix it, but that couldn't get that to work. Now the phone isn't showing up on adb devices either. panicking a little bit here.
Does anyone know what to do?

ADB won't work unless the phone is booted into Android or in stock recovery for a sideload.
Does your computer recognize the device when you are in Fastboot mode and type "fastboot devices"? Try flashing the factory image again but make sure you have the most up to date platform tools from Google. Old versions are a common cause of issues.
Did you flash TWRP recovery or just boot to it to root? If you still have stock recovery you can try a factory reset from there but any modified images you installed might be the issue.

like Fury said, your platform tools need to be updated, same thing happened to me.

What didn't work when you flashed the factory image? Do you have the latest sdk tools version of fastboot and adb?

Thanks so much, this is where I was going wrong. Have gone into recovery and rescued it.
Tried the process again to get Magisk working, but ended up the same although this time the white screen only went on for a while before I got an error saying my data was corrupted. Tbh, after all the stress I'm just going to give up on this and live with the phone in stock. All my drivers and adb were installed and setup today, so everything is up to date.
edit...
Not out of the woods yet. After restarting the phone and going through the setup, it's not detecting the SIM card or any wifi networks. I've installed the OTA and wiped data once more after having this problem, still not resolved.

It sounds like you are trying to install Magisk v17.1 like I tried. If so you need to use v17.3 beta. If you follow this thread you should be fine. It even tells you what to do for your original problem, just takes some reading and patience.

I tried it with both 17.1 and 17.3, so not sure what the issue is. Seem to have finally booted up properly with wifi and signal working, so hopefully it's all good now. Gonna give up on rooting.

my new pixel 3XL will be the first Android phone that I owned that will not be rooted.

Question [Solved] root problems

So I updated my phone to Android 13, after I updated my phone I needed to regain root perms, so I flashed a patched magisk boot.img file, it went wrong here.
so now(after) I am unable to start my pixel 6 pro, all I get is "Your device is corrupted it cannot be trusted and may not work properly", + the bootloader is unlocked message.
and whenever I start the phone it either shows a battery icon(as in it has no battery? idk it was on 20%) or the colorful "Google" logo, no it doesn't show the colored "G"/doesn't get to that point(as in it's stuck).
I cannot get the phone to show up in "adb devices" it has worked before.
I very much need help, I went throughout all of YouTube and Google(search) and found nothing.
Any idea?

can you get into bootloader and does it detect?

You must have flashed the boot.img that someone else uploaded from their phone? I did the same yesterday with the same result.
Fix....Use Android flash tool to flash the Aug update;
*****MAKE SURE TO UNCHECK lock bootloader, wipe device, force flash partitions. after it is finished.... copy boot.img to your phone and patch it with magisk. Then copy the magisk patched boot.img back to your PC and then flash your patched boot.img to both slots using Platform Tools CMD Good Luck

Okay I manage to get it into Fastboot, thank you very much both! much appreciate the help and your time!

Diff question:
I tried to(tmp) boot with the patched magisk boot.img but it doesn't seem to be willing to boot with it. how did you manage to get it to boot with the patched boot.img? is it any different than the normal android 12?
-- edit: I use my own patched files, that are not "made" by others. using the android 13 image file

I always download the full zip in order to get the boot.img for the zip, then I use Android Flash Tool to download and flash the full zip update. Let the phone reboot unrooted. If you have the magisk patched boot.img from your phone, copy it to your PC and use Platform tools to flash it to both slots using the CMD prompt.
Open a Command Prompt in the folder you copied the patched boot.img to.
Flash the boot.img (Magisk Patched) to both slots: fastboot flash boot <drag and drop boot.img> --slot all

Before you do any more modding, have you flashed the A13 bootloader to both slots so you don't get in trouble with the new ARB? If not, I suggest you do so before you do anything.
If you have, never mind, lol...

I've used the android flash tool, now shows that the phone is corrupt, Android Recovery -- cannot load Android system Your data may be corrupt. If you continue to get this message...
Try again or Factory data reset.
13.0.0 (TP1A.220624.021, Aug 2022)
Yes I got in trouble with the ARB
I don't really understand on how this works, I just follow a YouTube tutorial. not that i'm new(to rooting, been doing this from March~) but that just I don't understand on how android works, especially if a13 is different than a12
The tutorial I've used :

I'll try to recover the phone will see how it'll go, and if i won't manage i'll reset the device, I backed up via Google one.. i'm less worried -- data reset. was unable to recover

Fixed it.
so a little back story, at a random point in my day the phone(p6p) said restart to apply update, and I was rooted at the time and thought it would failed, and I went for it. it did manage to install(2nd "July" august update). then I saw a vid about A13 and thought I might aswell try to install A13 on my phone, I opted in the beta and downloaded A13, took a little bit but I manage to install it aswell.
I think this was the problem. I don't know as to how, but maybe magisk or some module manage to make the device itself think it's not rooted.. albeit it shows that the bootloader is indeed unlocked.
Needless to say, I managed to fix the problem, gained root perms again. thanks for the help and your time! much appreciated

Opting into the Beta wasn't necessary before manually downloading Android 13 - if that's what you meant.
Now that you've opted into the Beta program, you should unopt out of it, otherwise you will continue to get beta versions of Android as opposed to stable.

Question Google pixel 6 pro bootloops after root

I have been trying for a while now to root my phone with magisk. Everytime I go to root it at the end I go into a boot loop and can't go to recovery then I have to reinstall the version of Android 13 I'm using but still never rooted when I do so.

Rooting pixel phones are pretty straight forward and not much difficulties. Two different approaches:
1. If you are an experienced user and 100% sure what you are doing, then go back to your rooting process step by step to make sure you didn't miss anything.
2. If you are not sure that you have done everything correctly, then I would suggest you that you follow the steps which describe in this thread, believe it still the most detail explanation for rooting the pixel phones even today. https://forum.xda-developers.com/t/...ootloader-update-root-pass-safetynet.4356231/
Also posting your question on this thread could get you quicker response.
If after your trying of everything you still couldn't get it done, then describe your entire process when you ask for help without people have to guess what could went wrong.
PS: The only information which you shouldn't follow with that thread is "NOT" to use the latest platform tool, stay with version 33.0.3, version 34.0.1 has problem.

I had the same issue. Right after flashing when booting for the first time it got stuck in a boot loop. Factory reset fixed it.

Stupid question also could be the wire your using and usb port

If you guys are bootlooping after flashing Magisk patched image...
You should use the Google's official Android Flash Tool to reset your device to a working state...
Then you should use badabing2003's PixelFlasher to root; it automates most of what's needed to root, and it has checks and protocols to make sure files are correct, versions are correct, and the right procedure happens in the right order -- taking out a lot of guesswork or mis-steps that might be happening that is causing bootloops.
Many/You would be surprised how many times PixelFlasher succeeds where many have failed; almost miraculously and/or inexplicably! It's why it's become rather famous tool for Pixels...

Previously rooted with Magisk modules?
Incompatibility with newer updates is more often than not the cause of bootloops.
Rebooting into safe mode will disable them.
Press and hold volume down when the bootloader unlocked warning screen appears. Then let go as soon as you feel a vibration.
You will boot into safe mode and modules will be disabled.
Then reboot normally and go into Magisk and re-enable only safe modules such as USNF.
Test the others one by one until you find the culprit. Usually it will be a font changing module or an AOSP mod .

It's pretty straightforward provided you have an unlocked bootloader, USB debugging and platform tools, The latest works for root alone btw.
In terminal
Code:
adb devices
Authorise adb in the popup window
Code:
adb reboot bootloader
If fastboot isn't recognising your phone install the USB driver
You may find it easier to install the driver in fastboot.
Code:
fastboot flash boot <path_to_magiskboot.img>
Code:
fastboot reboot
Profit.
Assuming you've patched the right boot.img file from the .zip within the factory image zip file and you're using magisk from github.

sorry, i just made that assumption because you put the fastboot command to installing/flashing the image right after the sentence -- i made the mistake of connecting the two...
i should've known better as i was already initially confused as you don't install the driver AS a fastboot command...!
