Recently purchased an unlocked V3xx from ebay. It appears to work on all networls except 3, is there a way to change the settings or would I have to remove the ATT firmware by flashing. As it is a 3G phone I assumed it would work on 3 network here but I just get "no signal" when I enter the 3 sim.
I have tried flashing using RSD Lite and have Flash&Backup as well but I'm not entirely sure what I'm doing and don't want to brick the phone. There seems to be a multitude of firmwares around and I would be grateful if someone could point me to the correct one(s) to use.
I have the R26111LD_U_96.66.72AR_LP0039_DRM0010_VSTU_207_0C_J PUK_R26111LDH3G_02_USIZRGBLH3GUKR26111055_1FF.sbf which I believe is the 3 uk firmware.
