Looks like you screwed up, and if i am not mistaken you can no longer sim unlock that phone. It is locked to AT&T now. I hope I'm worng, but if there is no fix then you might as well sell it to someone in the US.

From what i understood in the posts i directed you too, you need another sim unlocked E970. Then you make an EFS backup of the second phone and replace the EFS files from your phone with the ones on the second phone. Downsides: Your phone will be a "clone" of the second phone since they will have the same imei, and you need to find another unlocked phone.

"Introduction
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)
/dev/block/platform/msm_sdcc.1/by-name/m9kefs1
/dev/block/platform/msm_sdcc.1/by-name/m9kefs2
/dev/block/platform/msm_sdcc.1/by-name/m9kefs3

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.
