Have you opened the visa-free patch? Open the visa-free patch and install it later. If it doesn't work, please delete the signature and reinstall. If it doesn't work, then you haven't cracked it successfully. I wonder which firmware version you are using. The visa-free patch was opened in rompatcher, and you should know how to remove the software signature. After cracking, it is the permission of 19. Your authority certificate 17 may lack the authority required by eight artifacts. Anyway, I cracked it on 4 13, and it worked well. If you don't understand ... meet me in dospy. My name is wppa998.
