Nexus 7 (2012) Bootloop help? - Nexus 7 Q&A, Help & Troubleshooting

Hey guys,
So the other day i was flashing my nexus to stock, and that all went fine, but when i went to OEM Relock it, my Nexus came to the Google boot stage, and wont go past that at all, i could leave it there for 8 hours, and nothing would happen. It is no longer rooted, and when i try to boot it in to recovery mode, there is an android symbol with an exclaimation mark. Though, i can boot it in to the Bootloader. Can anyone give me a hand? i'll be willing to do anything since this is my last attempt at salvaging my Nexus.

I don't actually need help, I'm merely ****posting so I can post in the thread I want to post in.

[Q] Nexus 7 wont boot

I was playing a game on my nexus 7, it froze then when rebooted it it just got stuck on google screen. Read a bunch of stuff, went into recovery and tried to recover, it would say erasing but never go any further, just sits there. got toolkit tried to restore factory with that, now when it boots I still just get google screen but I get the menu in corner for start/boot/recover/power off. still never boots, when I try to run recovery now it doesnt even go to erasing. Ive read everything I can find to restore it, got 2 toolkits, unfortunatly everything tells me to put it in debug mode, which is funny cause if I could boot up and go into settings to turn on bebug mode then I wouldnt be having these problems... Can someone please help, Im good with computers but dont know much of tablets. I did no messing with tablet besides downloading updates when they came out.
unlock bootloader

My guess is no, I never messed with any of my system stuff. Everything was factory except for the updates it had me do as they came out.
How long you let it sit in recovery erasing before you rebooted it? Is there an option in boot loader or recovery for a factory reset? Beings you're not rooted I doubt those one click tool kits will work for you.

It sat in erasing for 1 hour and didnt do anything. I was doing factory reset in recovery.
As long as the boot loader starts you can recover your Nexus. Check this guide: http://forum.xda-developers.com/showthread.php?t=1907796
If he can't unlock the bootloader then there's not a whole lot he can do. Run "fastboot getvar all" while in bootloader and tell us what it says please. If adb is seeing your phone in recovery, then run an adb shell and do "ls -l /dev/block/platform/sdhci-tegra.3/by-name/" please.
Sorry I can't help further but I just got this and don't know much. I am glad others came in to give you more help.

Damn... I didn't see he can't unlock the bootloader. This is going to be difficult.

Just sayin, I think you guys need to pull the back cover and disconnect the battery for at least one hour.
I am really new at this but it helped me save mine twice. I think?
After you plug the battery back in try fast boot.

But this will void my warranty right ?
They have no way in knowing you pulled your back cover off. Just be careful so not to leave pry marks. Only way they will know is if you tell them you did it.

[Q] hard bricked and SOL it seems

I really think I am going to be out of luck but here is my problem.
I was simply changing fonts using Rom toolbox on my rooted N7.
Rebooted and it boot looped. I let it go for a while but nothing. So i tried to reboot into recovery and i am stuck on the google logo screen. Nothing. Happens.
I can't do anything.
Any suggestions?
S.O.L. i think.

No. it's really gone. Just spoke with google and getting a replacement. I really can't do jack....bleep...with it.
all this for changing a font with Rom toolbox.
Yeah, bricked, but I'll buy it for 30
So it's permanently stuck on the Google logo and you can't access recovery or bootloader? No boot animation?
I wonder why something so trivial as a font change caused this... I've had font changes cause bootloops but never a bricked device.

You aren't alone.
That app is made by the ROM Toolbox dev, lotsa complaining in the reviews about it bricking. You did connect it to your PC via USB and tried pushing the needed bits and starting from scratch didn't you? I'd even try one of the toolkits available for rooting and recovery.
After several several hours, I was able to reboot into recovery. It was very tricky and I had a bit of luck on my side. I have since vowed not to use rim toolbox again. Thanks
As long as you see something on the screen, it is not bricked.
I bricked my first N7 by drunk flashing an updated Galaxy Nexus bootloader on my N7. Needless-to-say the backlight wouldn't even light up. Even then it technically isn't bricked. I could use the NVedit tool if I had the right files and commands.
I'm glad I was able to fix it. My computer was not able to recognize the device while I was on the fastboot screen (android laying down.) THe only other screen I ever was able to get was the bootlooping screen. By chance I realized the computer was connected to the device only if it was on the bootloop screen. When I saw that, then I was cooking with fire.
Sounds like you should install your fast boot drivers

I've only just got my nexus (first tablet) had it for two weeks, decided to root mainly because I hate adverts popping up everywhere, anyway I digress. I purchased toolbox pro for my hox ages ago and even though I haven't installed it, for the last few days I've been thinking of it so cheers buddy for bringing this to my attention

Best. Idea. Ever.
Also, with a Nexus device at least that was a shot. Many others would keel over and die for good if that sort of stuff happened.

Cool, and agreed with the above. If you can see stuff on the screen, it's technically not bricked.
Bricked an N7 once, it was stuck in APX mode, the lowest recovery mode for tegra chips I believe.
At the time there was no way recovering from it using NVFlash, maybe there is now though.
Mind telling us how you got yours back to life? Just curious
Cheers
all nowellel
Was really luck. I was working on trying to get the computer to sees the device. Trying to load drivers. Anything I could do. The computer kept saying no adb device plugged in. Finally after deleting drivers and reloading drivers, I plugged in the device while it was bootlooping and heard the correct "connected" sound and saw the device in device manager. Then with toolbox, was finally able to reboot into recovery and wipe and reinstall rom. Didn't lose anything in the process.
Oh, the thing that was really the biggest mind blower was that there were 2 screens I could get to, bootlooping screen and what appeared to be the correct fadtboot screen, the computer would not recognize the device when I was on the fastboot screen. That was why I thought I was SOL.

What is this NVedit tool? I cant seem to find that anywhere. I'm working on my buddy's N7 32GB Wifi, he tried to revert to stock from having CWR and CM10.1 using the Nexus Root Toolkit and now there is that problem happening you mentioned, backlight wont light up and computer doesnt recognize the device and I cant get into the bootloader either. Already checked the Screen itself and it works (disassemble and connected to my N7) and the battery has power, just no luck.

[Q] Refurb Nexus 7 with no Google

So I got a Nexus 7 refurb off of woot and booted it up with no GAPPS. So I unlocked the bootloader. At some point during my efforts to push a true stock image to my 7 the stock img was delted... yay. I am now fastbooting an image using the Dead_Nexus_7 bak. Problem is it has been pushing system now for over 30 minutes. I wouldnt think it would take that long to push. Can anyone who has pehaps had to do this before confirm that it takes this long or longer?
Of course if you have experience with this and have an easier method I am all ears. I am stuck in bootloader currently.
Thanks!!

I am in a very similar situation.... although mine came from Woot with GAPPS, I did the OTA 4.3 update (not sideloaded or anything - truly OTA) and now I get stuck at the boot animation Nexus "X".
Cannot access recovery - I get the dead Android with "No Command"
Frustrating.

Weird Bootloop issue

Hey can't really figure this issue out. I gave my girlfriend my old Nexus 4 when I purchased the Nexus 5 and it was running perfect... stock but unlocked and rooted. Recently she was letting her little cousin play with it, it somehow went into airplane mode and she restarted it and now it just gets stuck at in a boot loop at the Nexus logo. It will sit there for HOURs. I've now flashed it to stock twice, once using the .bat file and the other time just doing it with adb commands and still nothing. WTF happened?

Are your erasing the cache and flashing all 6 img files?

Yep. Might try to install clockwork with a custom ROM next and see if that does anything but I really want stock Android on it.

Personally, I like TWRP on the N4. I've never had any problems flashing custom ROMs with it.
Personally, I would use fastboot and follow this thread:

Stuck in bootloop

Stock, up-to-date. Using my Facebook app, and phone seems to freeze. Black screen, with Google. I can access bootloader, but NOT recovery mode. My warranty expired like 5 days ago. Am I SOL?

If your bootloader is unlocked you may not be. Search for items you can Flash to fix the bootloop issue. I don't have the URL handy sorry. If your bootloader is locked you might be in trouble. There are some tricks in the same fix post to tell you how to try to get back into your phone and then once you do get the bootloader unlocked quickly so you can load the fix

Yeah, I never unlocked the bootloader. I let it sit for a few hours, turned it on for S&G, tried and succeeded to get into Recovery mode for a few minutes, but because I forgot the way to access the menu. It dropped back into the bootloop. Going to try again in a few hours, now I know how to access the menu, I'll try wiping cache.

If your not gonna send for warranty I would unlock your bootloader. Also get your hands on the 4 core modified boot for your Android version. Find out more in the BLOD thread.
