IMEI Null, have nv_data.bak , not able to overwrite :(
I tried the Galaxy S unlock software from the market, and now I am getting null/null as IMEI and I am not able to use it on any network..
Now, I saw in my sd card, there is a file nv_data.bak , that is around 20mb file...now I am trying to overwrite the one that exits in the efs folder, but its not letting me do it, saying I don't have enough space...
I am not even sure if the nv_data.bak is the actual file, I mean its like 20mb..is it supposed to be this big?
Would really appreciate if someone can tell me how to proceed from here...
I am currently on 2.2.1 Froyo.VUVKD1 kernel and 188.8.131.52 firmware.
