[Q] Stuck into boot screen - Nexus 7 Q&A, Help & Troubleshooting

Got problem with my device. I installed a custom kernel now my device just stuck into boot screen. I have no backup so I tried to push a custom rom to my nexus 7 from my computer using cwm but it didnt mount to m computer. I also tried to use Nexus Root Toolkit to push the custom rom to the device but it also didnt work. How can I fix this??

Please Help.. My Nexus 7 is still stuck on bootloop..I used wug's Nexus Root Toolkit and flashed the factory image but still it didnt work..

try to flash other kernel...... franco kernel works very well.....
wugs toolkit should work for you....
can you put your nexus in bootloader mode? if you can don't worry your tablet is not totally bricked.....
boot your tablet en bootloader..... open wugs toolkit an select back to stock and unroot(select that the device is semibricked and tell us what happen)

New Nexus 7 User needing Unlocking/Root advice

Hey XDA
Iv had my Nexus 7 for a day now and am dying to root and mabe install CM10
i currently have a Samsung Galaxy S3 with CM10 on it...thot its extremly buggy sadly... anyways i have been looking up on how to root the nexus 7 but i need to know if i can instead of using toolkit can i instead just use odin to flash stock rom and cwm and so on instead of having to unlock the device?
i am used to using odin for flashing and cwm but here the nexus is close to the same with htc one x in the way it has that fastboot thing and from what iv heard the nexus 7 requires unlock before it can be rooted, also is the tookit the best way to unlock and root the device?
also does unlocking break the warrenty and if i ever decide to return to stock unroot how do i flash stock rom back onto the device? am not sure where i would find the stock roms for it and also can odin be used to flash it...:S
i hate sounding like a noob lol
ok iv used the toolkit 2.0 and its worked great so far...im stuck at not being able to boot into cwm recovery
it installed fine thru the toolkit but whenever i try to hold up and power i cant get it to boot into cwm recovery...
i tryed to reinstall again but still cant get it to boot into cwm am i doing something wrong?
Doing the following won't cause you to loose warranty:
- Unlocking the bootloader
- Rooting
- Flashing custom ROM's and Kernels (however, if you flash a custom kernel that causes your device to explode... I'm somewhat certain this won't be covered)
However, if you are doing anything like that, and have to send the device in for warranty, you "should" factory restore it. Google provides Factory Images for the Nexus 7, which can be restored to your device with semi-ease.
I use this guide to factory restore: http://forums.androidcentral.com/ne...ide-factory-image-restore-your-nexus-7-a.html Some filenames might need changed though since I think that guide is based off an older factory image (instructions are the same though).
There is a good chance a toolkit also has an easy method for factory restoring, but I don't recommend this at all.

I've never used a toolkit before (until this issue had me stuck). I'm unable to get the Nexus 7 to book into recovery (CWM) after flashing it via fastboot. After giving up, I rooted it using the toolkit.. scariest thing I've ever done.. it did work.. but I'd like to get to the bottom of why a number of people like me seem to be having issues flashing and booting CWM on the Nexus 7.
Did you rename the original system/recovery to .bak first?

No, I flashed it as I normally do.. using the .img file. In this case, CWM.. recovery-clockwork-6.0.1.0-grouper.img
Why would renaming it to .bak be needed?

I had to rename the stock recovery under system to .bak before I could get twrp to work. Or else when I went into recovery it would get stuck on the android.
But I see you are using fast boot it should write over it.

I didn't have to. Flashed twrp and forgot to put a ROM on it and went back into recovery and it was twrp still.

[Q] Nexus 7 (4.1.2) can't root

Hi I have a Nexus 7 version (4.1.2 OTA).
I wanted to ask what the deal is or what I'm doing wrong. I purchased the full version of Nexus ToolKit 7. According to the instructions I made the unlocked bootloader and I wanted to root but each attempt failed.
I do not know what I could do wrong when root is fully automated.
PS: I also tried to reflash Stock Rom (4.1.2)
I enclose a picture attachments with an error message

Hi. Yes mam (usb debugging on) have a look to the attachment.
Toolkit me boot into fastboot then reboot then for something to fastboot loaded and back to android and trying to upload the files but nothing superuser is not recorded because of (read-only file system).
have a look on the attachment is there to see everything ...
yep same issue here - problem with the forum regs is unless you have enough posts you can't actually address the issue to the appropriate person can you? Anyway, able to unlock but then is unable to root and rest due to a permissions problem. have tried as administrator but of coure this doesn't make any difference.

You can try flashing CWM recovery and installing Superuser from there.
Download Superuser and copy it to your /sdcard
Flash CWM recovery
Install Superuser from CWM
????
Profit.

Thanks comminus - but I think that if we could do this then we wouldn't be using the tool kit.

Why not try before you give up? Nothing I suggested is even remotely challenging.
With your tablet booted normally plug it in to your computer and copy the superuser zip in my previous post to the Download directory on your Nexus 7 from Windows.
Judging by the first provided screenshot I can see that option 6 in that toolkit is for flashing recovery. Why not try that?
As far as how to install the zip from ClockworkMod (CWM), there are literally hundreds of threads and YouTube videos that will show you what to do. The better option is to spend a few minutes (literately. It only takes a few minutes.) to learn some basic fastboot commands. If you're willing to learn there are many people who will help.

Thx you for your post
But in the Nexus7 ToolKit can be done but is ClockworkMod must first rename (recovery restore files) but with da only when I have ROOT.
And why unnecessary to install CWM and resolve other problems I'll eat a connection. If "simply" can I ROOT who create me rich enough.

Choose #1 in your first screenshot.
After you install CWM make sure you boot recovery before a standard boot. On rebooting from CWM it will say something like "ROM may flash stock recovery on boot." and prompt with yes or no. Choose yes - this renames /system/recovery-from-boot.p and prevents the ROM from restoring stock recovery.

I'm not really sure what you're trying to say...
I tried quite a few times to root my Nexus 7 with the Nexus 7 toolkit, it hung every time when it was supposed to be installing SuperSU and BusyBox. Every time the last message I saw was "adbd already running as root", and it would just hang there. Everything else appeared to work properly. The only tool I was able to successfully use (more than once) was the Nexus Root Toolkit from Wugfresh http://forum.xda-developers.com/showthread.php?t=1766475. You may want to try that tool.

Oki THX u i try this tool...
I'm also having this same problem but here's my story:
Using the Nexus 1.5.4 Toolkit, I Unrooted + Flashed jzo54k, success. I locked OEM, success. I unlocked again, success. Then I ran the root process again, and it keeps freezing at the android recovery screen. Following the prompt in the toolkit, I walked away for a few hours hoping time would resolve the issue.
If you're wondering why I unlocked + rooted, and decided to unroot, lock, unlock, and root again, its because I'm super-noob to anything android related after version 1.5, I wanted to learn the processes after I found out I was having troubles with certian things after my Nexus 7 updated from 4.1 to 4.1.2
I am having the same issue as you. 4.1.2 is not rooting for me. I can't install CWM or TWRP because it needs to rename recovery files, and to do that you need to be rooted. If I boot in recovery I always get stock
Having the same issue with a stock 4.1.2. I can unlock no problem but I cannot get it rooted. Everything appears to have worked, but it is not rooted. If I revert back to 4.1.1 I can unlock, root, etc. without issue. I was able to root 4.1.1 and use the root keeper app to then update to 4.1.2 and I was rooted still. However, it would not let me install CWM or anything. ROM Manager says it was installed, but booting to recovery always too me to stock.
Any ideas?
Can you point me into the direction to downgrading?

I used Nexus Root Toolkit v1.5.4 and selected the "Flash Stock + Unroot" option. When prompted I choose the default 4.1.1 option and away it went.
To root my 32Gb on 4.1.2 I had to unlock the boot loader, flash the boot loader back to version 3.34, and then I successfully rooted using the nexus 7 toolkit.

Try this root toolkit
Try WugFresh's toolkit if you haven't, it might solve your problem.
mediafire.com/download/97g6e8a5870rp4y/NRT_v1.6.3.sfx.exe
try downloading a fresh copy of the rom you are trying to flash it may be corrupted

Try fastboot method always the best way and most safest way to return to stock.

Since you're using toolkit before, so you may skip driver installation section because it should be already installed.

[Q] Flash To Stock Issue - Nexus 7 (2012)

I have a Nexus 7 (2012) that was rooted and unlocked and I am trying to return it to stock 4.2.2 with the Nexus Root Toolkit v 1.6.6 since 4.3 fails to install OTA.
However the program stops after entering fastboot and wont flash the stock image. I tried it on two different computers with the same result.
Im at a loss why it wont flash the stock 4.2.2.
Any help is appreciated. Thanks.

Still cant flash to stock with Nexus Root Toolkit v1.6.6
Thoughts, anyone please.
You said it was rooted and unlocked, I guess you also have a custom recovery installed?
try downloading a flashable stock image(go search for it) and just flash it. Or you could just install other ROMs like PA or Cyanogen.
Thanks for your reply. It is appreciated.
I used the Nexus Root Toolkit to unlock and get root access, however I didnt install a custom recovery. Not sure where to go from here.

[Q] Nexus 7 (2012) - TWRP No OS Installed - Are you sure you want to reboot? Bricked?

Hi, I booted into TWRP recovery mode to attempt updating my rooted Nexus 7 from 4.2.2 to 4.3. I wiped system, dalvik cache and cache. I also (stupidly) wiped data and internal storage too. Now I cannot turn on my Nexus 7 fully, it only shows the Google insignia with the unlocked boot loader icon below it.
I can boot into recovery mode and I can USB host, I tried copying a zip of the stock 4.2.2 ROM for Nexus 7 wifi onto my flash drive and tried flashing under the "install" section on TWRP but it always fails (I do not know why).
I cannot connect my Nexus 7 to the computer. Can anyone help me out, please?
Use adb side load in advanced settings
adb sideload nameofrom.zip
adb sideload gapps.zip
Reboot
Profit

Agreed, the toolkit works like a charm.
I had also deleted the whole Os and fixed it with the help of the toolkit.
Not sure why folks keep telling you to flash a custom rom when you ha e clearly stated that it fails. So, heres my two cents......
Since you already wiped the internal memory and there is no chance of data loss, just download the stock image and fastboot back to a fresh system. And for gods sake, dont use wugs. Just use good ole fastboot. There is a very easy how-to in the stickies of this section. This forum is full of problems arising from toolkits, that could have been easily avoided by fastboot.

I SECOND that use the toolkit from wugfresh for this.
ADB sideload and Fastboot is a real pain with TWRP don't know why the file does not get pushed at all.
Save yourself time and just use the toolkit if it's a Nexus device if Samsung find a similar toolkit tool
The site for toolkit is wugfresh . com ( no urls so the space )
Hope this helps someone
Good luck
