I recently flashed my Telstra s4 (Australia) i9505 to 4.3 than I flashed back to 4.2.2
but the phone isn't registering a sim card in it anymore. After flashing a few things It eventually
found it but i tried to upgrade it agaim to a later version of 4.2.2 and It stopped seeing a Sim Card again.
I've gottem all the firmware off of Sammobile.
What do I need to do to fix it.
