If it does not work, try installing ADFU using another computer.
As a last resort, you might want to consider getting an exchange with your seller. Since you have opened the player, what is the memory chip's serial number? That would be the largest rectangular chip.
Likely any replacement player would also be hacked, so you might want to consider between exhange or refund.
