[Q] Help with flashing back to stock/unrooting. - Nexus 7 Q&A, Help & Troubleshooting

Hello, I am in need of help. could someone please give me the original stock rom for the Nexus 7 (2012) I have recently used cm installer to install cyanogenmod. However, it has recently caused some issues with charging/syncing. I can only charge the device when off, and it won't show as connected on the computer. Also, how do I flash stock from device, since I can't connect to a computer? I would like to automatically unroot after flashing original stock rom, if possible. Kinda like a factory reset.

If you cannot use a computer, you cannot revert to total stock. However, you can try TeamAndroid's ROMs found on GooManager which are exact replicas of stock. Good luck.

Can't you download a flashable ROM from XDA and flash that zip?

Am I Soft Bricked?

Here's the rundown:
I installed the Dark Paranoid Android (Grouper) ROM this morning. I flashed Gapps, and rebooted the device. No issues at that point, because I came from another ROM I did a clean install and got through the registration screens no problem. Once at the home screen, I remembered I had not flashed the Trinity (Grouper) kernel like I had planned, so I rebooted to recovery and flashed it.
That's when I ran into problems. Rebooted device and it stuck at the Google screen. Tried to bootloader into recovery, I still get stuck at the Google screen. Have tried to boot up both the recovery and into Android several times from bootloader, but I always get stuck at the Google screen. I guess my device didn't like the kernel, or somehow installing it damaged my recovery maybe?
Basically, I am asking if I am soft-bricked and have to restore factory and therefore wipe the device clean. Doing that would suck, but it's better than not having the device.
Also, I'd like to know if it's possible to flash stock through the Wugfresh toolkit without removing root. I just want to get back to stock so I can reinstall the ROM and try a different kernel.

Impossible with my device in the state I described.
Since the answers were fairly slow I already flashed factory image from Google with the toolkit. Issue was resolved, just will take a while to get everything put back on it.

Did you check the md5 on the kernel download? If there wasn't an md5 supplied, download the file a few times and compare the md5's between them for consistency. Could've been as simple as a bad download.

I did not check it. Maybe I will try it again later. Was able to right the problem by using the Nexus Toolkit to flash 4.1.2. Then I put DarkPA on it and started over. Not really the end of the world, just slightly time consuming.
I love the Trinity kernel on my phone. I want to use one for Nexus but I didn't see a stable one yet, all are in experimental phase.

You also need to install the Google Apps package.
That won't help. It is not required to install for a working ROM. You only need Gapps if you want the Google apps like the play store. It sounds like a bad flash or a bad download. Try to reflash through recovery, if that doesn't work, boot into recovery and mount your tablet. I don't know what recovery you are on, so i can't give you info on how to do that.

I don't use CyanogenMod but sometimes flashing a patch is also need afterwards. Nonetheless, before continuing with experimenting different ROMs, it would be wise to flash back to stock then make a Nandroid backup on your device, one on your PC and one in the cloud. Installing MultiRom is also highly recommended.
My guess is that someone didn't factory reset in recovery before flashing.

Manually boot into recovery by holding power and volume up and volume down at same time. Then when you see the around laying down select recovery with volume key. Try restoring a backup or flashing another rom in recovery.

Can´t boot nexus 4- blue screen problem

Hello fellow internet users, I've been trying to resolve a problem I've been having with my Nexus 4 device, but given that I failed, I came here hoping somebody here could help me.
Recently I wanted to update CM Mod on my device (to the latest version supporting Android 4.3), but little did I know that it'd replace my recovery program from TWRP to ClockwordMod. Afterwards I proceeded to install Franco Kernel (r. 193) since from what I read it should have been compatible with my recently downloaded version of CM. After I flashed it, all the tints of blue on my screen turned into tints of orange/yellow (and vice versa). Afterwards I tried to fix it with flashing one of the supposedly stock kernels I found on the internet, however all it achieved was to make it unable for my phone to boot - now when I turn it on in normal mode all I see is a weird blue screen with intermittently flashing pink squares that create a checkered pattern. I tried to access the android root kit to unroot the phone and bring back the default kernel + rom, but so far I've been unable to access my phone from my PC. And in case you wonder, yes, I was stupid enough to not store any backups on the internal storage.
I hope there is a work around it, since I really need my phone to work , thanks in advance to whoever can provide me with some sound advice.

It sounds you had flashed a wrong version of kernel for JWR and JSS. If you can boot into recovery, then just download another ROM and save it to your phone. Wipe factory reset and then flash the new ROM.

Thank you for the swift reply. The problem is, while I can boot into recovery, I can't save anything to my phone right now since I can´t access it from my PC.

Were you able to connect your phone to your PC prior to flashing the CM mod? If yes, then you can mount it while in recovery. If no, then I suggest you might want to spend some time reading the materials which software that you will need in order to connect your phone to your PC.

Yes, the problem is that I did all the previous operations on another computer (on which nexus usb drivers were installed too), which I'll have access to in around 10 days. I was simply curious whether it is possible to find a workaround the fact that the computer I'm using currently doesn't recognise my device/can't install drivers, regardless of the mode my phone is in (bootloader, recovery or normal).

You'll have to install drivers manually.
Your problem is easily fixed. You don't need to wipe anything; that would be unnecessary. All you have to do is flash your ROM again. You can't use custom kernels with cm unless they are made specifically for it.

Kernel Emergency

Good morning.
So I'm running KitKat on my Nexus 4 and everything was fine until I decided to install TouchControl to avoid using the power button that much. I'm not an expertise over kernel's so I followed the prompted instructions and I ended up flashing the stock kernel I guess.
So after that my phoned rebooted, and since then I can not connect to Wifi, it only says connecting. I don't have CWM on my phone because I have a problem connecting my phone to my computer since it got wet some weeks ago so now it only charges but I can not transfer any files into my phone.
I restored my phone to factory settings and nothing.
I know this will be tricky but I also know you guys can help me, I know the main issue will be the fact that I can not transfer files over USB.
Please your help you will be of so much help.
Thanks in advance

Does ADB work?
If the phone is rooted, grab Flashify off the Play Store and install CWM or TWRP from there.
Have a custom/stock kernel zip to flash on your sdcard.

Did it say that 3G didn't work?
Problem fixed
So at the end I figure that the problem was caused by the Touch Control App, I did not put the required attention to the prompted instructions and the kernel was flashed.
So, using my phone's BT I transferred the files to install CWM and then I flashed it with the stock ROM.
That's the way I recovered the WiFi Capability.
Thanks for your advice guys.
Cheers.

Nexus 10 stock rom

Hello, I got cyanogenmod installed on my nexus 10 atm, it came with it, when I bought it second hand, but now I want to install the newest stock rom(5.1), how can I do that, do I install it from recovery like a custom rom, or via pc?

Follow Method 2 in the OP from this thread: http://forum.xda-developers.com/nexus-6/general/guide-flash-factory-images-nexus-6shamu-t2954008. Although it's for the Nexus 6, all steps are the same for all the Nexus devices. Just make sure you have the correct factory image for the N10. Not sure if you have to wipe userdata when going from CM to stock, but I probably would just to start fresh and make sure there are no issues down the road.
