Lg K550 unlock error

[beckam_laci]

Hi,

I'm having problem unlocking a LG K550 network locked with T-mobile app (not eligible for unlock)
The phone is, and was working perfectly without any issue.
I let Z3X search for the phone, then press unlock but it can't detect my phone. (USB debugging is enabled)


I did:
-unlocked bootloader
-flashed TWRP (later updated it)
-have working superuser (updated it)
-enabled test port
- ADB is workig and showing for any other command, example.: adb devices or install some apk etc. (check pic)
-reinstalled LG drivers from z3x support + lastest LG drivers from LG US (4.2.0 version)
-all is showing ok in device manager (check pic)

It seems that everything is ok and working, except when i press unlock it does not find it.

Please help me, advise me what to do next
Thank you

Yes...tried that before like 10x, changed cable, changed port. Like i said if i open adb and give any commands to phone, install x.apk or check "adb devices" its shows. So it must be something else
