@maxant69 TWRP installed or official recovery ?
It may have a serial check… But I probably don’t have all the requirements (ID changed, not official beta tester)… I also highly doubt the serial check is part of the archive. It would never works with my device
@maxant69 OK that a significant difference. Would you try to install twrp (unlock bootloader http://forum.xda-developers.com/meizu-pro-5/how-to/tutorial-unlock-bootloader-meizu-pro-5-t3303127 then flash recovery http://forum.xda-developers.com/meizu-mx/general/tutorial-install-twrp-pro-5-t3348845 )
