The only solution is to change your MAD2 (CPU) from the v18(ROM5) to v16(ROM6).
This is not simple. Requires highly skilled technicians to do it.

mad chip is the cpu , the flash ram is a different chip , iff the flash ram is not glued in the 8210 , then it can be replaced with rom 6 version . however if it is glued then you cant , having said that , i have changed glued component , its a very messy job and possibility of breaking a track is very high rendering your phone dead .
