I own a red t-mobile branded 5800, and my product key is 0577187. The v40 firmware is still unavailable. I am considering changing my p-key with JAF, getting v40 from NSU, and changing my p-key back afterwards. Has anyone done this before? How safe is it? After my pkey is changed back, will my warranty still be lost?
Sorry for the many questions ._.
