I want to reset my rooted nexus 7 running rom 4.4.3 and TWRP recovery in order to sell. I just want to clear data and passwords. do I need to do a hard reset and upload a new stock rom or factory reset from recovery. thanks
Download the factory image from Google (Android 4.4.2 KOT49H) , unzip, for Windows run flash-all.bat OR for Linux flash-all.sh in the root dir. I did mine in Linux, takes only 2 minutes.
