I am using XT1521. ROM is almost stable except the sim is not detecting. I got two errors while installing the ROM. Not sure how someone with the same model got their sims detected.
Also, there is a bug in turning on the Airplane mode via power button menu. Once enabled from this menu, one cannot disable the Airplane mode through power menu. Even after turn off this mode, this option will be enactive.

I don't know if it has any dependancy with the sim card not detecting, but when I checked the *#*#4636#*#* option for radio band, I could only see USA band. I selected it accidently. Now when I switched back to CM13 but my SIM 1 was not working. I tried to select the band option again and saw three options; Auto, Euro and US. When I selected Auto, sim card functioned properly. Was it because this CM 14 was ported from a US variant, the Indian variant has an issue in SIM card detection?
