Anyone can help to solve this problem? I tried to flash it on lg download or even lgnpst but still failed...other may have passed but 3-5 mins it went back and says "service required". I have flashed the scr, prl, eri, bin, emergency, refurbish but still failed...it has no prl on phone info but if you read it it has a prl. Im wondering why and how to solve this problem.
