I'm unable to unlock my TF300T device.
After having installed unlock_v8.apk, checked "I agree" two times, the following message appears upon attempting to unlock device :
"An unknown error occured, which may be a network issue. Please wait and try again later."
I have tried many times and my WiFi connection is all right.
I have activated developer and debuging mode, no changes. Tried unlock v7, asked on other forums, no changes.
Some system information for your help :
