mobile

Hi,

I have already backup my stock rom using TWRP before flashing custom roms from this forum, after that, I use restore in TWRP to back to stock

After reboot, I was asked as if my tablet is fleshy started, then MOBILE PHONE & DATA is broken...

Here are my P7500 P4 (3G) symptoms :

1) Settings->About device->Status: MDM UNKNOWN...
2) SIM seems partially working, radio signal okay, Carrier detected, about my phone no. is not working... & there is no apps to dial out...
3) All my PHONE-related APKs disappear, I already checked Setting->Application, Phone is not running at all

Plz. help me... I did not play with the mdm partition at all, I swear...
