Works as we know last month ..It doesn't work on mine tried fastbooting it but give black screen only
You can flash the new twrp 1206 or you can boot to twrp ..
But it's written a thousand times that you have to wait almost a minute until twrp loads , the black screen will be passed and twrp will load if you wait a minute ..
And the error "failed to load authenticate boot.img" , it can be passed easily , just re-enter fastboot mode with buttons , phone must close and re-enter to fastboot to pass the command ..
