GD90 are in two series: A & B series.

Using USPU
1. Open GD90 flasher and click on read version and then power the phone

2. The phone version will be Axx or Bxx.

3. If xx is version 13 and above (eg A16 you must select flash file A12). If B version then select version B12 flash file.

4. Disconnect cable from phone, click flash phone then quickly plug cable to phone

5. Green light means phone is flashing. Usually takes about 8 mins

6. Phone can then be unlocked using USPU

Basically you need to downgrade the phone to ver 12
