Hello !! I tried to unlock my OT-991 that's locked in Orange Romania. I downloaded MTKRacer module and MTK_Android_Unlock_Drivers and I installed the Android drivers. Next, I connected the OT-991 powered off phone via USB cable and I run MTKReader.exe. But, the window appears and diappears instantly. Can you help me, please to unlock my OT-991? Or can you send me an unlock code based on IMEI and ID provider? Thanks in advance!!! Sorry for my english.
