how to return to stock rom?

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

TWRP and backups

I recently made a backup of my stock rooted ROM using the latest TWRP recovery so I could try out AOKP. After a while I decided to flash the stock backup.so I booted into recovery ,factory reset(data/cache) and then proceeded to restore my backup. When I attempted to do this no backups were listed! I even checked the twrp folder and there was no backup folder present. Has anyone else experienced this ?

Yes. Try looking in /data/media ( I think that is where it was but I moved mine and am going by memory) for another TWRP folder. That is where mine saved to. You can move it to the regular TWRP folder and it will be seen for restore.

Sweet thanks. I don't get why it is saved there though but I'm glad I know

Reflashing system partition?

I'm trying to upgrade my SuperSu to the latest beta so I can install Viper4Android for Angler. However, the instructions for SuperSu Beta states "If you are coming from any SuperSU install in /system, you must re-flash the stock system (and vendor and oem, if present) partition contents prior to installing this."
I was wondering if I could get some Nexus 6P specific instructions for doing that without screwing everything up. I assume this doesn't wipe my user apps. Thanks.
If you are comfortable with using ADB and fastboot, follow Section 10 of this guide. All you need to do is "fastboot flash system," just download the factory image that matches your current rom.

Flashing just the system partition does not wipe app data.

Yeah, I'm pretty comfortable using adb and fastboot. I'll try it out. Thanks!.
Quick question, can I keep the TWRP recovery or do I need to flash stock recovery too? Thanks again.

Cool! There is no need to touch the recovery partition. Just fastboot the system and vendor img's then boot right into TWRP and install SuperSU

I screwed it up. Flashed everything just fine. Didn't have the SuperSu beta on the phone yet, booted to system. It tried to re-encrypt the device. I interrupted it because it seemed to be stuck. Now, I have to factory reset and lose all of my data. Not sure where I have to restart now, root, etc...

Ahh dang, were your able to get set up? If the rom is messed up, you'll likely have to fastboot flash system, boot, and vendor IMG's for the 6.0.1 OTA you already downloaded.
I wasn't aware that you were decrypted, I would have been more expressive about not booting until things were flashed in recovery. SuperSU removes "force encrypt" from the stock boot.img so that would not have occurred.

Nexus 7 (2012) WiFi Reflashing Issue

Hi guys!
I just want to get some idea of what could be the real problem of my Nexus 7. I can boot on its bootloader, i can access also it's recovery menu. The problem is my Nexus is in boot loop. It can't pass through the nexus boot animation (5.1.1) and I am trying to downgrade it to 4.4.4 or at least fix its' boot looping issue.
I tried reflashing a stock ROM via cmd and Nexus Toolkit, still it didn't resolve the problem. It looks like the whole partition was in READ ONLY that right after completing the flashing procedures and rebooted it all went back to the same problem. Bootloader is Unlocked
I would appreciate if someone can give me an idea on how to resolve this. TIA

Check if cache partition is there if not create in recovery
Sent from my Nexus 6 using Tapatalk
Cache is present also..
Thanks for the input..

My N7 has latest Pure Nexus, GApps and Parrot Mod. Try flashing it by first formatting system, data and caches. Recovery is TWRP 3.0.2 If it boots performance will be much better than stock

Will try that.. Thanks!
