The problem here is that while I try to root with the bin4ry file, it always says to me there is no Backup & Restore app (which is true) and just waits for me to open the fake backup, which never shows up.
The most similar thing here the AT&T My Locker, which I cannot use because I'm from outside the US and in my country there is no such thing as AT&T.
By the other way I try to use the NUT's Dual Recovery (XT-lockeddualrecovery2.7.123-BETA.installer). It always tells me it was successful, but when I try to go to the recovery, It only turns on normally (obviously I always stay pressing the Volume Up button even after he shows me the AT&T logo).
So then, what should I do?
If anyone can help me I will be eternally grateful.
