Hi, I've got a Chinese Meizu Pro 5. Currently I have 6.1.0.0A installed. Other users have told me about the possibility to change the PROINFO text file file in the root folder /dev/block/platform/155700000.ufs/by-name/proinfo to machine_type=M576_intl_official. They suggested to downgrade the firmware to 5.1.2.0G before trying that. I have tried this, but every time the phone is restarted, the value changes back to the old value. Is there some way to reliably allow me to install international firmware?
