Everything worked out great! No data loss, phone is now updated, and TWRP is gone from my phone! Thanks for all of your time and help!
Hi, I would like to have the same thing, updated and stock and I'm rooted with CWM and TWRP but on stock ROM. Thing is, I see this thanks but I don't see a solution above it, in between when you posted your question with the death note and this.
Could you point me to the process you followed? I've been flashing a stock recovery via Note 2 Toolkit, then Triangling away the flash counter, then full unrooting from SuperSU, then factory data reset + wipe + cache wipe, but device still says modified.
Any ideas would be greatly appreciated.
