how to return to stock rom? - Nexus 7 Q&A, Help & Troubleshooting

Is there a zip file i can flash to return to stock rom? similar to flashing custom rom.
i would like to avoid using the nexus toolkit's restore factory image feature as it would wipe my device and its internal memory as well.
is this possible?

As far as I know, you can only return to the stock ROM by flashing the stock image.
Yeah, the downside is that you loose all your data. Could you do a nandroid backup and then just restore the apps? Or even titanium backup. That would fix your problems

Or use the toolkit to back up your apks n data

[Q] Is it safe to flash Cyanogen 10 on top of a non-stock kernel?

Hi, if you're reading this, thanks for taking the time to help me. I want to flash Cyanogen 10 on to my rooted Nexus 7. Its currently running the stock JB 4.2.2 ROM. A few days ago I flashed the motley kernel (build #249 for Jellybean 4.2.2) to OC the CPU to 1.6 Ghz using ROM Manager to flash and Trickster MOD to OC. I understand how to flash Cyanogen 10 to the Nexus 7, but is this safe? I've heard some users report that they get a boot loop when trying to flash Cyanogen 10 on top of a modified kernel. Has anyone here experienced a problem doing this?
The kernel lives in the boot partition and that is formatted when the new rom installs and it flashes its own boot.img into place. No worries. Just make sure you do a factory reset and wipe system prior to flashing cm10.
Okay. So I should boot into recovery, then do a factory reset. After that, unlock bootloader again and re-root. Then install Rom Manager again, and flash CM 10, then flash motley kernel?

A recovery factory reset does not relock or unroot your devices. Pretty much every rom out there will be pre rooted. So what you are going to do is download your rom, boot to recovery, perform a backup, factory reset, format system, then flash rom and gapps package and kernel, then reboot.
Oh awesome. Thanks for the help!!

Install twrp?

So I am running cm10.1, cwm touch recovery and the cwm app for management. I would like to switch to twrp so that my backup files will be accessible to move to and from my PC. When I try to install twrp from the cwm app it just gives me a message that the app is configured to work with my current recovery, and backs out. I did pay for full use.
How do I get switched? Thanks.

Nevermind, i used Nexus 7 ToolKit to do it...
all you had to do was fastboot flash the recovery image or use goomanager.....SMH. toolkits have made people utterly helpless.

Because I don't know what app it is I have no idea what it did so what I would do is go to recovery and do the following command to every file you want:
adb pull /sdcard/Some_file.txt C://Users/Your_name/Desktop/Some_folder/Some_file.txt
If possible you can make a backup of the internal storage and restore when you reflash your rom or something if you have TWRP also moving the image file to your PC using ADB Pull.
After backing up you have to use this tool with your device on the bootloader menu: https://developers.google.com/android/nexus/images#occamjwr66v
You can restore your files afterwards but if you originally used a custom rom then flash the custom rom.

Why would you want to go back to stock recovery in the first place?

[Q] Update to 4.3 Verification Failed?

I'm trying to update my Nexus 7 to 4.3. But I get a "Verification Failed." and it doesn't update.
I'm running Android version (4.2.1) on franco's kernel (3.1.10) along with Paranoid Android (2.99.)
Do I have to factory reset my Nexus? I'm mainly worried about my data and apps, as I don't know how to backup all of that info.
Thanks in advance.
Is it the ota that fails? You have a custom ROM, kernel, and recovery so expect an ota to fail.
Do you want stock? A new custom ROM?
Always make a backup in recovery of current setup in case you mess anything up. For most apps and data use something like titanium backup, this is often the easiest way to restore stuff in new ROM

Ah so I need to be on the original ROM and kernel for OTA? Is there another way to update besides OTA so that I don't have to go back to stock?
What I am trying to accomplish is to update my Nexus 7 to 4.3 while keeping most of my data intact. I guess I'll have to invest in Titanium Backup, thanks for the suggestion.
Just follow THIS guide. This way you can get the stock 4.3 without restoring the original rom/kernel/bootloader relocking. But you still have to save all your data.
