I tried it with iroot, kingoroot, kingroot and I can't.
And I also tried the meizu method, but I completed the questionnaire and he told me that my phone number is wrong.
I need the privileges to use different apks and the last time I did root, it was very easy. But with the new rom Flyme 7.3.0.0A I can't.
Can someone help me, even if it's like putting the phone number (not Chinese) and having the website accept it.

Thanks in advance
