Help build the Qin F21 PRO Ultimate Guide

[dfrydman]

when you put an sim card in it wont register with any tower. but it could be they made it intentionally like that as @william said so maybe we can reverse it

PLEASE HELP with new version qin F21, different hardware and ROM

I was told from a couple of Chinese suppliers that was exactly it’s intended point Not sure if it has to do with the whole situation with the manufacturers deal with the f30 The f30 was supposed to be the only workable USA version initially
