Thank you for ur prompt reply but kindly advise me a little more here;
I am currently on TWRP recovery. Bootloader unlocked.
Rooted and using custom rom AICP.
what are the exact steps in short that i shuld follow to get back to official stock rom and recovery and with bootloader locked.
I mean weather i shuld lock bootloader first or flash rom first or what?
The rom link is chinese in this video, you need to download indian stock rom
