My Verizon Note II phone is running Android Version 4.1.2. It was rooted using the Team Win Recovery Project rom with ODIN. Yesterday, I unrooted my phone using Chainfire's SuperUser app. My phone appears to be working normally and there are nearly no signs that it was ever rooted in ODIN Mode. The only giveaway is that TWRP bootup is still there. I cannot successfully update my phone to the next version, and I believe the TWRP bootup has something to do with that. I want to return my phone to factory default. I thank you for any assistance you can provide me with this.
