I have upgraded my Phone with the help of LG Support tool from 4.2.1 to 4.4.2 (I suppose ). I have upgraded with LG support tool because I live in Pakistan and OTA was not available in Pakistan
Its regular Upgrade no hack. All went normal no issue during upgrade. Now when Phone booted Its asking me a password. But language is Korean I am unable to understand which password. I actually tried all. Please see the screen Shoots.
Also Some one suggested Reboot in recovery mode Phone is not going in recovery mode I tried all thing Power + Volume Down.
Now when I try again with LG support to reinstall OS it say Its fully updated cant don't any thing else
