Hi I'm Mica fr. the Philippines.
I've got this problem for over a month. There's a pop-up notification saying there's a Software Update so I click install. After I've successfully installed the new firmware I'm unable to receive outgoing & ingoing calls and texts. Can somebody help me with this my phone was stocked in EMERGENCY CALLS only when you pull the notification bar. I tried to root it to downgrade it but there is no use. I wiped it already worked in a while but it came back again. I upgraded it again so I could ask if it was covered in the warranty. It says no, it will charge you in big cost. I don't have enough budget for this, but if I am able to fix it with myself I might even be proud of myself. What Am I going to do? I hope someone could answer my Q's thank you so much SamMobile!
