[Q] Nexus 7 Won't Boot

Hi, basically i recently flashed the miui rom via rom manager on my nexus 7 and once it had flashed the rom it went to restart and it won't go past the mi boot screen. I also can't go into recovery via fastboot mode as it just goes the google screen.
What Should I do?

I think you might still be able to re-install the stock ROM.
Go to this thread and scroll down to "Q. I want to send my phone back so I need to flash a stock rom and relock the bootloader". You should probably read the whole post in case I missed something.
Good luck

I don't know if this will help but from what I've read you can't get into recovery through fastboot unless you're plugged into a pc. What you can do is plug your tablet into the pc and then hold the volume up/down buttons as well as the power button. Then just select recovery and you should be able to get into it.
I'm not an expert on this but it has happened to me where I would get stuck at the google screen so I did a lot of reading about it. From what I understand, this is an issue with the bootloader. It was designed that way and this problem will continue as until google decides to fix it.
I hope this helps

Stuck in Bootloop

Guys,
I installed CM10 (official) onto my Nexus 7. The ROM was running perfectly, no problems whatsoever. I then decided to flash the Elite kernel. I made a back up via Clockwordmod before hand, just in case anything went wrong.
I then installed the kernel and now all I get is the CM10 spinning green boot screen. That's it! I've installed Wug's tool, to try try and boot into recovery, but I can't even get the drivers to install to even use the tool... which is massively annoying.
Spent an hour last night searching for a solution and trying to get this thing to boot into recovery.
I've tried the obvious by holding down the volume rockers and then holding power, I get to the screen (I can't remember it's name) where you can toggle through different selections via the volume rockers, I select Recovery but it doesn't work.
Any ideas?

Make sure your Nexus is plugged into your PC, then you'll be able to get into recovery from the bootloader. This is the well known workaround for the problem with the original bootloaders.
Also, upgrade your bootloader to 4.13 as that version fixed the problem of getting into recovery.

Thanks.
Daft question, I'm not 100% on upgrading the boot loader. Can this be done on the device itself? If so, how?

Yes. There's a flashable zip file that you can install using recovery. Search the Development section.

HELP! Bricked Nexus 7, cannot boot into boot loader

Hello everyone, I'm new in this forum and have just bricked my Nexus 7 .
I was not very happy with my Nexus 7 with JB version 4.2.1, it lagged and took long time to load apps etc. I used the Nexus 7 toolkit to unlock my bootloader, flash recovery and then tried a few custom roms. I eventually flash the official 4.1.2 firmware from google but the constant notification for firmware update annoyed me and I decided to root and get rid of the firmware update notifications by installing fotakill.apk.
But when I tried to root using the Nexus 7 toolkit, I chose the option to sideload the zip files for rooting automatically. It asked to flash my boot loader to a lower version (3.34, mine was 3.41) and afterwards it rebooted the device and eventually got stuck at a screen with these lines:
now send the package you want to apply
to the device with adb sideload <filename>
after a long time without anything happening, I suspected that things went wrong and pressed the power button for a few seconds and the device turned off. Now I cannot turn it back on, when plugged in it doesn't show the charging battery, also I cannot boot into fastboot mode by holding Volume down + Power button. The screen stays black the whole time.
I even tried to open the back power and pull the battery out and in again and try to turn on the tablet, nothing happens. I remember the battery level was like roughly 90% the last time the tablet was working, so I don't know what went wrong .

I tried that but nothing happened .

Press all buttons on the side simultaniously untill fastboot/bootloader mode appears. This should work, no matter if your device is booted or not, or soft bricked or whatever. Then: http://forum.xda-developers.com/showthread.php?t=1907796 .
If it doesn't work however (like after 30-60 seconds), then connect your nexus 7 to your PC. Go to device manager and identify your device. Does it say apx-mode or something like that? Then your device is possibly hard bricked and you might find some answers here: http://forum.xda-developers.com/showthread.php?t=1879228 .
Your should not have used rootkits. Most of these topics appear after people using toolkit. Learn to use fastboot. It's the only program you'll need for the nexus 7. Yes, it's a command line tool but at least it forces you to think before flashing. For example, it was not necessary to downgrade your bootloader. I really don't get why you did that. Also, if you want to run a stable 4.1.2 without the annoying update messages, you can, for example, flash cyanogenmod 10. It's stable, very smooth, and way better than stock.

Thanks I did a search and finally found an answer. I was running fine on my N7 with PACMan and suddenly it got stuck booting up. So I booted into recovery and reflashed the ROM, and wiped dalvik and cache. When I rebooted it went to "Android is upgrading" like usual after wiping dalvik, then it got stuck there. So I rebooted again and nothing. Just a blank screen. Your suggestion of holding all the buttons down for 30-60 seconds awoke my Nexus. I'm going to wipe everything and start over.

Nexus 4 stuck on boot up.

So suddenly phone died, tried to restart it but its stuck at the loop of Paranoid Android. Battery was still in 40%. Tried to go recovery mode, hold volume down + power button but all it does is go back to the google logo and loop again to the paranoid android and get stuck again.
Tried plugging it to mac, android file transfer says " try reconnecting or restarting your device."
Im on Franco and paranoid.
what to do?
PLEASE HELP.

tried reflashing a recovery via fastboot(while in the bootloader)?

Not sure if this will work for you, but its worth a try. Attempt holding the power button while its booting up to allow it to turn off (do not let it go when the screen turns black). Then hold volume down and quickly release and re-hold the power button.

The bootloader is the fastboot screen
There you should be able to use ./flash-all.bat (extracted from the stock rom)

Nexus 7 No Recovery/No Fastboot RESOLVED PLEASE DELETE

Hey XDA!
Got my Nexus into some trouble today. I Was running stock rooted 5.0.2, received an OTA update for 5.1. Ran the update and it sent me to my TWRP 3.0 recovery. Restarted the device and found out the update did not work, leaving me at 5.0.2. Ran the update again like a tard, took my to the stock bootloader. TWRP is now no where to be found... In fact there is no recovery to be found. When I select the recovery option in the bootloader it goes to black screen then redirects back to the bootloader. When I select the "start" option, it's reboots the device taking me to the bootloader. I have attempted a hard restart with the power button but the device hangs on the Google logo forever. I have tried to use the Nexus Root Tool but it can't help me since the device won't connect via fastboot, or ADB.
Any help is appreciated.

Hallo,
got the same problem, how did you resolve it ??? Thanks a lot ...

Same here. I can't connect to the device by no means. How did you solve your problem?

you mention it wont connect via fastboot but you can still reboot with the pwr + vol- to get menus of some kind.. ? if the screen is backlite even just a blank screen but you can see it light up theres still hope. All i can say is try to reboot the device into fastboot an then try Nexus Root Toolkit an see if you can reset to Factory to restore the stock recovery partition along with reset the OS to which ever you select and start over .. Good Luck Flashing... the only way i can say your SOL is if when you plug it into your PC an it pops up with the error "Device Malfunctioned,....." then you SOL Good Luck Flashing :good:
EDIT: Sorry didnt notice it was resolved in the title..
