I had temporarily rooted my phone before with z4root and i just recently reset it to system default.. (home button + power button + volume down key on start up) i wanted to let it update to 2.2.1 using the LG Updater (SN: I Updated it to 2.2.1 before but downgraded it using someones thread on here) but now i want it to update but while going through the process, after the first step, i get a "fatal error" and it wont update.. has this happened to anyone?
