My Nexus 7 isn't restarting, or booting, or responding at all. Dead. Screen won't even turn on. Blank.
It was my first time trying to root it. Should be simple with Toolkit 2.0, right? No. After successfully unlocking it, I proceeded to Root it. The Toolkit told me to wait till it restarts in Fastboot Mode. So the tablet automatically reboots, but to normal Android. Nothing's happening. So I decide to power it off and on maybe it'll boot in Fastboot mode when that happens. Aaand it's gone now. Windows cannot recognize it when I plug it in, but there's a response (as if it know 'something' was connected to it).
Please help. It's my first time doing that, and I haven't had the Nexus 7 for more than a few hours. I only did that so I can use my USB OTG.... Thanks.
UPDATE: Scratch that. Everything works now. I plugged it in the charger for a while (even though it was 49% to begin with) and then tried powering it up and it worked. I got it rooted too. Delete this thread if you want!
great to see you got it working!

Hello ! I really need help at this moment, i don't know what to do ... Really !
My Nexus 7 was in CM10, but 1 week ago, my tablet runs out of battery (turned off completly).
I plugged in, turned it on, and it bootloop on the Google logo. I mean i see the google logo, turns off and go back to the google logo, endlessly....
I tried the recovery mod to go back to the stock software... But i get the android's robot laying on it's back with a red icon....
No ADB status, and i cannot install the drivers with the nexus root toolkit ...
I powered it off, unplugged, plugged it, and let it charge all the night, but i get the same problem.
So .... I opened the back, see if there's any problem with the battery, disconnected and reconnected the connector, nothing suspect ... Turned on, bootloop on the google logo, super ... :good:
From this, i tried this method from XDA how-manually-unbrick-restore-your-nexus-7-s-factory-state-windows (can't post URL Ha!)
And tadaaaa, that's working now, i can access to my nexus 7 with the 4.1.0 Android, but ... I cannot access to the network ( it's connected but i get a grey icon with these little arrows...) and the battery shows 0%. If unplugged, my tablet turns off... Also, number of notifications show "......" as stoped working.
Now, i have the ADB status, that's pretty good, so that i can install the 4.2.2 Android version with the nexus 7 root toolkit. During the installation, at the end (when the tablet bootloop on the nexus logo with the color) my tablet turned off (maybe runs out of battery or a problem ? Don't know ...) ...
I plugged in the wall charger (not the computer) and my tablet restarted. See the google logo, after the nexus logo, and restart, endlessly ...
Now i don't know what i have to do, i'm completely lost. Do you think i can do something last, or i have to return my Nexus ?
Sorry if it's confused at some time, i've not a good english.
Thank you in advance
I think you failed to attach your battery correctly. Try disconnecting an reconnecting the battery. Than power down the tablet(Power button for 10sec if turns back on press power and volume down and choose "Power off") Than recharge your tablet using(Charger is better than PC). Now try flashing or installing Android. Should work. Let me know if doesn't.

I've already did that! It's correctly attached ...
I think that everytime i tried to install a new OS, my tablet turns off because he runs out of battery, whereas i though i was due to an error .
I've retried the method i gave above, Third times.
It's working now in Android 4.1, but if i try to update, my nexus restart again and again ...
Very annoying because i can't access to the recovery mode --' ...

I do think so ... It's the original OS
Thank you jesus ! ^^
I've saved my nexus !
I post the solution:
You just have to follow the guide, named as "[HOW TO] MANUALLY UNBRICK / RESTORE YOUR NEXUS 7 TO IT'S FACTORY STATE (WINDOWS)" on this same website. (As i'm a new , i can't post URL at this time)
You must do the installation twice or more, because sometime, the nexus 7 reboot endlessly on the google logo, or on the nexus logo.
I needed to do this three times in a row to get a full and complete Android 4.1 working .
From that, i followed another guide. (because if i try to upgrade to the 4.2.2 OS, the nexus 7 is also blocked and i got a non stop reboot tablet)
Just go on google and type this "How to install cm10 jelly bean on the google nexus 7 using twrp recovery"
This is a youtube video that shows you how to download and install the Cyanogenmod10 in TWRP recovery mod.
(To access to the TWRP recovery mod, you can also use the Nexus 7 root toolkit by clicking on the Advanced button)
And voila, that's working now perfectly for me !
Hope this will help
hi all,
i had the nexus player with me and installed cm12.1, everything was working fine, i had it at the hotel i was staying at. no issues whatsoever. but after i unplugged it and brought it back home, i plugged it back in and it just bootloops on the google logo. the bootloader is unlocked.
i tried pressing the reset button while powering it on, but no luck, the leds dont flash quickly to enter fastboot.
ive tried also keeping the reset button pressed again while powering it on, and eventually the led will blink slowly. i then let go, but then it just brings up the google logo again and will bootloop. tried plugging it into the pc while doing this as well, but adb doesnt detect it either.
pretty cant get into fastboot mode or even the recovery mode. any hints or tips i should try? i dont want it to be dead after just 4 months of usage.
Lol I did the exact same thing in pretty good at getting out of a brick but the nexus player is pretty low on my list its actually been like this for about two months now and I haven't touched it
While the LED is blinking slowly have you checked to see if the device is enumerating over USB at all. I believe slow flash indicates recovery mode. Do you ever see Andy with an exclamation mark?

well I was able to get it back up and running by plugging it into my pc and messing with the drivers a little bit, then I used fastboot to flash the stock firmware again and now im putting a custom recovery back on it, all in all its pretty easy to fix so its definitely not dead for good. Sorry im not great with tutorials
howd you end up recovering. i want to get it back up and running. perhaps i can try another pc.
when the led flashes slowly, i have the hdmi cable plugged in, but it just bootloops, never gets to to the android recovery mode. first time ive had a bricked android device.

Boot into the bootloader by unplugging the nexus player and then hold the button on the bottom and plug it in. Let the button go when you see the google logo. Then just use fastboot to flash the stock firmware.
So, for a long time, my Nexus 7 never worked, because the charging port was too loose. So I decided to order one. It came in the mail today. Installation was easy. It started charging, but no charging icon appeared. The only thing that happend was the screen back light turning on slightly. So I let it charge more. The Nexus turned on!... But got stuck on the Google screen. So I try and use fastboot and starting it from there. "Boot failed". So, maybe no OS? Try using ADB to flash stock android onto the device. "Failed (Bootloader locked)". Ok, ill just unlock the bootloader. "Unlock failed (unknown error)" . Maybe flashing a new recovery will work? Nope, has to be unlocked. So far, nothing has worked. Spent 2 hours trying to flash, unlock and factory reset, and nothing but "failed" has come up. The device can't even go into recovery mode. When connected to adb, The list of adb devices is blank. It knows the device is connected, but it doesn't show the name or model.
Anyone know what to do?? (I have never tried to flash anything previous from today on this tablet.)
Hi guys,
I had Pure nexus rom installed:
http://forum.xda-developers.com/nexus-4/development/rom-pure-nexus-project-layers-t3237366
and everything worked fine for weeks. Yesterday I noticed that my nexus 4 is using battery too much, without any reason.. Then my phone turned off, try to restart but it was stuck on google logo. At that point there was 20 or 30% battery left. I boot it to recovery, wipe everything and tried to restore factory settings, cos I didnt have any backup on phone. But again it was stuck on google logo.
So now I cant boot it cos there's no system installed on it, basicaly there is nothing on my phone. I tried Nexus Root Toolkit, but my pc dont recognize my phone, when I boot to recovery it's still the same, so I cant install drivers..
At this point, I have no idea what to do.. Can anyone help pls?
Thx
Can you get into fastboot? Are you using Win7? Tried different USB ports and cables?

Thx for quick reply !
Yes, I'm using win7 64x, I tried all usb ports and 3 different cables and nothing. I can get into fastboot and recovery, but pc still don't recognize anything..
i am currently under the same situation
only difference is i can still fastboot and flash a recovery (twrp for that matter)
afterwards, when booting to recovery - i can install a rom
once the rom is installed, reboot does not boot into the ROM and instead just displays the google logo - then vibrates a little - then the screen turns off
I just tried on 2 other win7 pc's, still nothing.. Nexus root toolkit just can't establish adb/fastboot connection..
edit: other thing I tried is to copy ROM file on usb stick, and then connect usb stick with micro usb cable to phone, and when I'm in recovery (twrp 3.0.2-0) there is just ''internal storage'' option.. Is that normal, should twrp see external USB drive? Cos I'm thinking that maybe something is wrong with usb charging port (I replaced that board month ago).
Hi,
I have a similar problem:
I had my mobile in working condition and once when upgrading the OS to 5.0.1, it downloaded the OS and was upgrading. During that process, the charge got over and hence the phone was shutdown. There after, it was not proceeding further from Google screen when trying to reboot. So, i thought battery is dead and replaced the battery with a new one. Now, i am getting the following problem:
The phone doesn't turn on(not even getting GOOGLE screen now). But, If I keep holding power button and Volume down button and try to insert the charging cable immediately then i get the boot menu but it wont stay there for even a second and goes to GOOGLE logo screen and gets shut down. Please help me with this.
Hi guys,
I menaged to fix the problem, my problem was charging port (smal L shaped board) that I replaced month ago. That's why there was no connection.
I got another one this morning from ebay, and Nexus Root Toolkit established connection immediately.

That looks like a stuck power button.
Try just holding the volume down button and plugging the charger.
If you see the fastboot screen, you have a stuck power button.
Just experienced this issue on a Nexus 5 and I was able to recover from it by "massaging" the power button for a while.
All,
I have had my Nexus bootloader unlocked and even rooted it before.
However, I friend needed a phone so I let her use my phone...about a month later she said the battery was bad because the phone keeps cutting off.
Long story short I got the phone back and I think she picked up some type of virus or something got corrupted because I forgot to lock the bootloader when I gave her the phone.
Here's what I have found and done:
Found out:
1. The phone will turn on while plugged in after a couple of tries.
2.If the phone is not plugged in, it gets to the 4 dots and either re-boots or shuts off
3.If I turn it on while plugged in and then unplug it and set the display to turn off after 30 minutes...the phone will stay on, until the display shuts off then the phone shuts off.
Here's what I tried:
1. sideloaded Android 8.1 using TWRP (about 5 times)
2. Wipe cache and the other cached (several times)
3. Tried rooted it again...using SuperSu BUT during the re-boot it will stay on the "Google" screen for 30 minutes and not do anything...will not re-boot or nothing...phone get's really hot. (tried this several times)
4. Using TWRP recovery and if I leave the phone unplugged (while in recovery mode) the phone never cuts off.
So I am thinking one of these partitions is bad, corrupted or missing which is causing the phone to think the battery is low and cuts the phone off. Just guessing here. Maybe some malware is installed on a partitions and flashing is not during the trick.
Any suggestions???
I really wanted to keep this phone as a rooted phone I can play with and try different things.
Thanks,
Real

Not an expert but i suggest you do the following:
Backup the boot image, download the modified boot image for 4 cores. Try to boot, if it boots normally, your problem is BLOD and it will be solved. If that is not the case, use the 1 click flash bat from the modified fastboot folder that you can find doing some search, that bat will recreate partitions and reflash everything and also flash the rom you provide it then try to boot again. Shutdown the phone, give a charge until 90ish, let it cool and then boot it up.

Thank you for taking the time to reply...and thanks for your suggestions. I tried both and was very hopefuly...but did not work. The phone still will not boot unless the usb is connected and powered. However, not sure if I did the 4core correctly because I could not tell if it worked or not. I found a twrp 4core for bullhead and that is what I used. However, when you first flash it and it does an auto reboot it boots into TWRP not Android. So within TWRP I just click on reboot system...but same outcome.
I think maybe this phone's hardware is dead or something got burned out...but it is not the battery.
Thanks,

You did it wrong. You have to flash the boot.img that disables 2 of your cores. Search it here on the forum you'll find it
