I bought an AT&T LG Optimus G E970(1) on Ebay and I though it was asking my SIM code, so I put it 4 times and it got a hard lock:
"This phone is permanently locked and can not be unlocked"
I tried to find some kind of information about unlocking it but I was unsuccessful. I tryed flashing roms or restoring factory etc but nothing worked.
Even thinking was not really a hardware problem I though I can sell it for parts and buy another, because there was not any solution.
A kind of solution:
As I said I bought another E970(2) and I unlock it, in the process I make a backup of efs files and that gave me an idea.
I used the 3 files of my new unlock E970(2)
on the E970(1) and it bypass the hard-lock (IDK how is it made, but is not matter) working as a new cellphone clone of E970(2).
The plan was to put E970(1) hard-locked efs on the E970(2), and since it's not hard-locked, unlock the imei and put it back on the E970(1) since if you put a unlock efs imei it bypass the hard-lock but I failed (by mistake I deleted the backups of E970(1) efs).
I don't know how to change the data of those archives or generate new ones (and I don't want to upload mine because I have now 2 clones) but I guess if someone could help with that.
I hope it can help. "
You can make the EFS backup using freegee.
