. After flashing, I rebooted and did not get any mobile signal. I did some looking into it and my network is unknown, mobile network type is unknown, service state is out of service, not roaming, mobile network state disconnected, unknown phone number, IMEI and IMEI SV and Baseband version are unkown as well. When i try typing in *#197328640# and *#7284# a message saying "mobile network not avalible" pops up. My sim card is in btw and I am at a loss of what to do. I have already tried reverting back to a previous backup I made, but to no prevail. Please help!!
You need to flash a modem. (that's your radio/baseband/modem) that should fix all of your problems. Post back and let us know what happens.
