Looking for assistance with his phone I got recently. I had a play with replacing the ROM, now I cannot get the thing to connect correctly with NZ Vodafone.
It had a custom ROM when purchased, which worked well. But I cannot find a copy of this anywhere, only the original Japan versions. These end up sim locking the network to CDMA quite often.
I have tried SpaceX 4.2 rom, which also ends up locking the sim/network.
If anyone has had experience with these, or knows what I can do (other than selling it for parts..)
