I just got new Teclast air III 3G x98 64GB (C5J6, v2.00.20150720) and can't install Mirek v6 rom. If I try FLASH_tool_Teclast_x98_air3g_and_air_2-(v2.5).bat it wont connect the device, although my PC's Windows 8 recognizes Teclast when connected to USB. I also installed ADB drivers and Intel ADB drivers.
Then I tried using Manufacturing Flash Tool with instructions from here but no luck either. MFT gives error shown image below
What I am doing wrong? I have flashed multiple other Android devices earlier but this seems to be tough one
