I've never commented in any forum, ever; so please forgive me if I'm doing this wrong. I have a G900P PE1, rooted. I followed all the steps and did the PE1_FIX too. It didn't work. The sim is still locked. I'm trying to us a Cricket sim (At&t towers).
After I saw that it didn't work, I decided to flash Cyanogenmod13. Still nothing. So then, I flashed back to my Sprint backup. The idoneapps.com app shows the SIM State as "READY" but not "UNLOCKED".
How do I get it "sim unlocked" for USA GSM use?
