[Q] N7 won't boot anymore - Nexus 7 Q&A, Help & Troubleshooting

This day just won't end.
I flashed the ParanoidAndroid Rom + PimpMyRom and everything went fine until I decided to reboot. Not the N7 doesn't do anything anymore. It's not stuck at the boot logo, it just doesn't do anything. I've read that you're supposed to keep pressing the Power-Button for 30+ secs, well, I've done that. I've done that in combination with every other button, nothing happens except when I plug it in the PC and hold some buttons down for 45sec, windows tells me that an APX device was not installed properly. That's it.
Is there anything else I can do? I know there's a Reset-Button below the Volume-Buttons but it doesn't seem to do anything. Any idea what else I could do?

Use Wug's toolkit to reflash the stock Rom. Sometimes that happens. Click Here For The Toolkit. Once you download it, click the option "Reflash stock and unroot" or something. Check the box thing that you can't bootup.

so since powering it up doesn't work, according to the toolkit I would have to do a battery pull (not sure what exactly that is) or use ODIN...
any help with this?
does battery pull mean I just pull out the battery cable or do I have to do something while I pull it out?...

Download the Google Nexus 7 Toolkit which is sticked in the Android Development Forum.
Then enter Fastboot Mod, do a re-lock bootloader, then unlock again and flash stock recovery, it should work.

I...I can't. The N7 is not turning on. I can't do anything. That's the problem...
Is it possible that this is a SOD? I was using Paranoid Android Rom + PmR. Is there a way around this?

Check the links kenvan posted above.
You don't want to see the phone mounted as USB, you need to see it with the fastboot command from your DOS or unix terminal.
Then push ClockWork recovery to the phone.
From CW recovery you should be able to use it's tools to get you running again, or at least adb should work so you can mount storage and push files to it via adb.
I'd love to help you but I need a little more background... did you just buy the phone and this is happening? Or did you try rooting it and this is happening? Or did you just flash a different rom and this is happening?

Ok since you say you have a padlock on the boot screen, I assume you know how you unlocked the bootloader.
Turn the phone on into fastboot (hold power and volume up), then connect the phone to the computer via USB. Flash clockwork recovery (3.0.0.5 preferred) and then you should be able to enter clockwork recovery assuming you did it correctly. Push this rom (http://forum.xda-developers.com/showthread.php?t=884093) to your card and flash it in recovery.

Yes i know, can you be more specific`? step by step? im noob sorry for bothering you., how do i push to my card?
I have fixed my phone, my phone was liquid damaged. So i putted the hole mainboard in 100% alcohol and after 20 min i took it out and let it dry. And then it worked fine!
It just happened to me an hour ago. I tried for a few time to remove the battery and start it up (even with a new one). I also thought it might happen since the battery was drained so i let it recharge for a while with no success.
Eventually i attached the device to the computer's usb, waited and started it. and it worked.
Don't know if that was what solving it - but it back working.

[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 on google logo

Hey guys
i just wiped all my data and tried to reboot my nexus, but now it's been stuck on the google logo for ages...
trying to flash to stock + unroot with nexus toolkit doesn't work, any way to unbrick it?
please help...
do you have fastboot driver installed?
Step 1: Power down your Nexus 4 (hold the power button until it shuts off) before rebooting into fastboot mode. You can do this by holding down the the Volume Down and Power buttons simultaneously.
Step 2: Connect your device to your computer. Open up a terminal or command prompt, and navigate to the folder containing the fastboot program.
Step 3: Type fastboot devices into the command line, and you should then see your device’s ID, which means fastboot is setup correctly.
now go back to Nexus 4 toolkit. Flash back to stock.

Thanks simms, i managed to get into fast boot between the reboots, and I flashed the rom and gapps.
Damn it scared me even more then the red light issue that happened to me last month.

not booting after flashing something or modding something is the easiest of all to fix, just reflash the rom(gapps and kernel too if need be), no need to wipe anything. since i test all the trinity kernels before any get released, and pre-kernels, i get many that dont boot my device or bootloop(among some other funky behaviors), reflashing a good kernel always works
I left my phone for a few minutes, and when I picked it up it was bootlooped again, and i had to use fastboot again. What should I do now? Maybe a factory reset would help me. I don't want more unexpected bootloops. :/

Try another rom. You might have downloaded corrupted zips. Also, make sure you flash the things you need first. Eg, flash rom and gapps. Don't restore anything if you're using titanium backup. Try restarting the phone, see if it gets into a bootloop. If it doesn't, then try restoring apps from TB. (if you use TB.)
Hi!
I´ve got a big problem. Today i flashed the new PA version, but it seems that the download had some issue. I could install it but after a while, I wanted to reboot the phone and it got stuck at the Google logo. I can only access fastboot mode and recovery.
So the problem is, i made a full wipe, so i have no rom on the sdcard anymore. Also I am now able to enable the debbuging mode. I tried every toolkit i couzld find, but everyone needs debugging mode enabled. windows doesnt recognize the phone ( it says unkown device). So i tried to install the adb drivers, but nothing happens.
i wanted to try to push a rom with adb on the phone but it says no device found. i am such a noob, i hope some can help me.
thx

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.

Bricked Nexus 4

Hi folks, This is the first time I need help from this excellent forum.
Something weird happened. I was updating apps from Google Play and when Titanium (Pro version), came up my phone crashed. I'm not a total noob, Unlock, Root all of my phones. No I never flashed other ROMs
I've tried everything to unbrick my phone (Nexus 4, 5.1.1., unlocked and rooted, factory ROM).
Now my PC doesn't recognize my phone, it's stuck on boot screen, can't boot into recovery, (error 10), no Fastboot, no download mode, I can't do anything. I've unbricked my phones many times before. Can't install MTP device driver including other drivers. This one has me stumped. Been at this for 4 days.
Can't sideload. Power and other buttons don't work to boot into Recovery, Fastboot etc,
Obviously, can't do a "battery pull" on Nexus 4. Tried the 15-second power button trick to simulate battery pull and other button tricks. Can someone help?
I've searched the web for days, tried all the tricks.
Can someone help?
Cheers!
What buttons are you using for fastboot mode? What when you power it off, then while pressing volume down button, press the power button?

Thanx for replying Nitin

That's the thing. I've tried all the button combos. The problem is my PC doesn't fully recognize my phone so I can't access or push fastboot or ADB. It shows up in device manager but that's it, nothing else. The phone goes only as far as the boot animation and stays like that for days. I've soft bricked my other phones before but was able to repair them.
I get fastboot not found, ADB error 10. I've never seen anything like this. I also get an MTP driver error.
It got bricked by a Playstore app update then when Titanium backup pro came up, that's when it crashed???
I have a Nandroid backup on my pc but it's useless.
Thanx, I hope someone can figure this out. I'm running stock ROM, 5.1.1, unlocked and rooted.
I'm using Nexus Root Toolkit but can't push fastboot or ADB, because, like I said, it doesn't show in my computer???

Try using a friends windows laptop/computer and windows will most likely install drivers on it for you then use nrt to fix your phone from fastboot could also be a bad USB cable or bad USB port though

As far as I have seen, Nexus 4 can not be bricked You can even remove the bottom 2 screws to remove the battery, it is not so difficult (I can say that as I have replaced the battery, power button as well as back of the phone on multiple occasions)
Also try what @[email protected] has suggested.
Nitin
I used platform-tools-v16 and Universal_Naked_Driver_0.72 to flash stock room and unlock bootloader... worked fine. Maybe this helps...
