this is kind of how with the z3x box on any samsung you can just replace the imei then put back the original one and it automatically unlocks the phone. sometimes it nulls the imei and when you get to repair it, the phone becomes unlock as a "side effect". so with dfs tool you were able to imput your imei after you nulled it? or only after you installed your wife's efs backup then you repaired the imei and it stuck?
After I restored my wife's backup to my phone

Is the consensus that you need to back up the efs and restore it and that unlocks the phone?
Buzz. Nope. I tried that. Apparently Sprint's OTA unlock does more than alter the EFS/NV Items. Erasing the EFS on GSM phones unlocks them.

any good news?
I'm going to try something with the EFS if someone with an internationally unlocked Note 3 would be so kind as to let me lend a backup. I will NOT be using the IMEI/MEID in the backup in case someone was wondering.

Soft brick or hard brick? If so, have you checked out the latest in the N900T thread? I think Frank tested it out on 4.4.2.

Tried my theory on a S5. Apparently you cannot copy the EFS data from one phone to another phone despite them being the exact same model (it corrupts). I'm going to try it on a Note 3 when one comes through.

It didn't corrupt my efs.As soon as I clicked restore it fixed my signal issues and returned the original imei to my phone.One thing I do know is that if you try any other phone it will definitely corrupt it or even hard brick your phone.I still haven't fixed my phone yet so I'm going to buy a t-mobile n3

There's no possible way a EFS clear/transfer will brick a phone (unless you inject the data into the wrong partitions...at which point one discovers that they need to step away from the phone and computer...). You might soft brick. I've experienced this. But sending a zeroed out copy of nvrebuild1.bin and nvrebuild2.bin via Odin will get the device working.

I realized something after checking efs pro last night.Seems like I restored my GS4's efs and that bricked my phone.I have backups from 5 different phones and I must've selected the wrong one and it hard bricked my phone.My PC won't even detect it.Seems like it's a paperweight.I tried an unbrick img from my wife's working N3 and that didn't even work
