Is it possible to convert from 059R2L5 Amber Dev ROM to 059L848 Black ROM?

:crying: I've downloaded the 059L848 Black ROM from MrCrab site and attempted to flash over Amber Dev ROM using all three Nokia tools. All have failed. Frustrating and hard to believe that nobody has been able to 'force' a ROM on a phone without having the update tool verify product code. C'mon guys, I know you can do it!

many have tried with no luck. Read any of the "Flash Amber rom" threads and you'll see that there is no proven method to revert back.
I eventually got mine replaced
