Everytime i try to generate a testkey i get this message:
If i dont get it i must send it to pioneer and hope that it will not be so expensive to fix it...
Just ask somebody here in topic. For example, ml_homeboy used this key so he know where you can get binary version of this key.
Yes, you can send device to pioneer, but this will waste your money and time. Also you can restore your device just in 15 minutes using existing backup image.
