Hello everyone, a few months ago, my meizu m5c no longer receives updates is my flyme version is 6.0.2.0 and I also noticed that the serial number has become "0123456ABCDEF" from what I remember, how do I put back the serial number??
Even if I manually unload the OTA and install it with recovery, it says that the firmware is corrupt.
