Hi all was hoping somebody could help. I am unlocking a W610i too. The firmware on the phone is R1KG001.

I have downloaded R1KG001 firmware from here but only get a .fbn file.

When I run SIMlockPatchgen it asks for a .mbn file - where do I get this file from? Can I use the firmware linked on page 1 of this thread? and do these contain .mbn files.

Thanks, any help would be appreciated.
