I recently got HTC One locked to AT&T network and bought code online but it didn't work. I also made sure SIM card was active and had positive amount, not locked by PIN or PUK, phone is not stolen or blacklisted. Did factory reset and tried again but no luck..

First I tried it on stock phone:
- Android 4.1.2,
- Baseband version 4A.14.3250.13_10.33.1150.01L,
- Build number 1.26.502.10 CL166754 release-keys

Then I followed this guide [Tutorial] Root, Unlock, Recovery and flashing a Custom ROM ... unlocked bootloader, flashed CWM recovery, installed stock rooted 1.26.502.15 Android 4.1.2. I did not install custom rom/kernel.
Tried unlocking with code but again, no luck.

After that I followed this guide [GUIDE] How to Return to 100% Stock ... I got S-Off with revone, restored using a RUU.exe, removed Tampered.
Atm this is info from bootloader:
(bootloader) version: 0.5
(bootloader) version-bootloader: 1.44.0000
(bootloader) version-baseband: 4A.14.3250.13
(bootloader) version-cpld: None
(bootloader) version-microp: None
(bootloader) version-main: 1.26.502.12
(bootloader) version-misc: PVT SHIP S-OFF
(bootloader) serialno: HT34NWxxxxxx
(bootloader) imei: 3544390xxxxxxxx
(bootloader) meid: 00000000000000
(bootloader) product: m7_ul
(bootloader) platform: HBOOT-8064
(bootloader) modelid: PN0712000
(bootloader) cidnum: CWS__001
(bootloader) battery-status: good
(bootloader) battery-voltage: 4183mV
(bootloader) partition-layout: Generic
(bootloader) security: off
(bootloader) build-mode: SHIP
(bootloader) boot-mode: FASTBOOT
Do I have to relock bootloader and try applying the code again?
Please help me solve this problem. I'm willing to donate 20$ to whoever help me solve problem.

Edit: Should I try updating 4.4.2 zip OTA and then applying the code? Will that help anyhow?
