[help]Blu Dash 4.5

Apr 6, 2013
Guys, I'm having problems with a port for my phone Blu Dash 4.5. Miui installs normally but has some bugs. No SD card, no internal memory, no sound, no make calls. Push the button to turn off the screen and the screen does not appear again. Can anyone help me? Miui Version 3.8.2 android 4.2.1. Thank you!
