No Service on My LG Optimus G f180k.
Hello,
I just bought a LG Optimus f180k. I didn't like the Korean OS, so I downloaded and flashed an International version (E97510F_00.kdz) following some tutorials. Everything went smoothly on reboot exccept that I had no SIgnal from my SIM Card. I downloaded the f180k kdz and flashed it once more hoping I will have my signal back but it didnt. I followed many other tutorials here, where I read I had to flash the baseband to have my Signal back. I tried three different baseband flashing but none works.
Can someone help me get my signal back. Pleaaaassssssseee
