Initially, the phone Meizu U20 was not included after "Flashtool" firmware, I downloaded with firmware "20160803112700_prd_yunos_stable_5.2.4.0"
After that, he turned on, but there was no IMEI, I also restored it, but there is another problem with "nwram warning" because of what the sim-card does not work, disabled, how can I fix this problem? Perhaps there is another firmware for mrt?
