Hi K-Dix,
If your phone is A3x v20, don't flash it to v13, it will kill your phone! you can only use this solution for version 19 and below. But if you do flash it, don't worry
just flash it back to v20, you can download it from Dragonlock site
For version 20, well you have to pay for it
still not available for free. Software for A3x v20 is dongle protected!
Regards,
