The problem with invisible icons corrected – change themes.
The problem with empty lines in the menu do not know how to treat.
Themes work a little tight but work, go to the theme, try to download, will generate an error loading, restart the device. I have earned after a reboot.
In general, the state of the firmware in life. 3g sim card and the second did not check.
On the screen there is no network – SIM card is in the other machine, waiting for a call. Communication checked norms.
The original firmware is taken here http://miuipro.ru/roms/
