As is known that we can't downgrade from Rogero 4.21,4.30 or 4.31 without NOR or NAND Flasher!!!
But what i'm sure that don't know it if i can Downgrade to 3.55 CFW or OFW.
1-Did the 3.55 Recovery of backup allow me to back from Rogero 4.21,4.30 or 4.31 to 3.55 or not?
2- Is there any tools help to downgrade without flasher and loosing money? if there are, wondering if these stable or not?
