This firmware is for Cherry Mobile W17 you can only use this in the updated Volcano box, I tried to use this firmware in GPGDragon unfortunately the phone did not power up or turned on. So I decided to flash it in Volcano and it power up.
When using this firmware make sure that you have the latest version of Volcano software. The firmware has a password, you may need to format the phone to remove the password.
Without further ado, you can download the firmware below
