Now he doesnt know the original network that it came on or what the original firmware version was.
Before i even tried to get a sim card to work i unlocked it using the hidden menu with sha256 etc.
Now when i put in a sim card it doesnt register to a network, I am in the UK and have tried Three, GiffGaff and T-mobile sims as they are what i have and none of the register to network.
I have a couple of bars signal and the phone says "emergency calls only".
The IEMI seems fine and I have backed up the NV data using QPST and EFS Professional

What would be the next step to try?
