Hi mate!
i have similar problem with a similar phone (2610) And after two month i find a solution. there was a little metal dirt deep inside the easy flash socket. After i removed this 1mm x 1mm dirt the phone works again. But maybe if the easyflash socket is water damaged and u think its allready clean it can also sort circulit more deeper in the socket than you think. So try remove the socket, and check without the socket lockal mode still present.
This maybe helps
WBR
