I'm having problem with "Pantech Sky Vega A850L" .... I bought it used from the local market. It was working fine until after a day , I popped out the SIM & restarted the phone. Since then, it shows me a screen saying "System Restart because of Application Operation Error". I found a ROM online but dont know how to flash it as everything I found was in Chinese or Korean. Can any good soul here help me?
