P8 from GRA-L09 to GRA-UL00

Hi all,

I'm trying to change my P8 with MM from GRA-L09 to GRA-UL00 without any success. The Bootloader is unlocked.

I've tried (with UPDATE.APP) a normal upgrade and forced upgrade using a ROM from GRA-UL00.

Does any one know how to change the P8 from GRA-L09 to GRA-UL00?

Thanks in advance,
Deckardpt
