Brother you can follow Amar steps it's 100% correct. There is Another way you can use it ( if Amar steps doesn't work) follow me:
1. Do A FULL backup for RPL and full PM
2. Full Erase Flash
3. Flashing Again with which version you need
4. write your RPL
5. write your PM
6. Check super Dongle Area (if you found An ERROR repair it). a
7. All this steps I tested it with Advance Turbo Flasher

8.Good Luck
