Guys, I have a Blu Dash 4.5 with android 4.2.1. I found a rom compatible with my device. The rom is MIUI ROM 3.11.9 for Fly IQ446 Magic. Just changed the boot.img from miui boot.img with my stock rom. The miui rom worked! USB, internal memory and external camera. But I still find 2 bugs: no signal and no audio. Could anyone help me solve this problem? Thank you!
