A7108 dont boot after reset pattern lock

hi there

i just tried to reset pattern on a7108, failed on loading ADB device and now dont boot, phone has Crom lock on its download mode
any way to recover to previous condition?

and there seems there's a bug on 34.1 sw for this model, reset pattern can find the phone without choosing port on ADB, but no other function can detect the phone.

thanks in advance for reply
