Im using samsung galaxy s5 g900f and it was working perfectly. But yesterday idiotic me entered an mmi code which is *35*0000# so all my incoming calls and sms' barred.
After that i tried its neutralizer to go back normal which is ##35*0000# but it didnt work. I tried dozens of mmi codes but it just stuck in there?!
Anyway after that i go back to default options menu on the phone. Call settings -> additional settings -> call barring -> bar all incoming calls. It asks for a password which is defaulty is 0000, it gives error and goes back. Tried to change password and it gave error too.
Wipe cache, hard reset, root, custom rom i tried every one of them to ger rid of this sh.t but i couldnt. Even samsung support couldnt help me. Please please help !
