[Q] L7 P700 KDZ Flash error Wparam/Lparam

view story

http://forum.xda-developers.com – As stated in title: - Updated to stock V20X (no root), then tried to flash V10k rooted/CWM/bootunlock etc. - Can't flash through KDZ updater whatever the mode (DIAG/EMERGENCY) because of a Wparam/Lparam error every time followed various tutorials to the letter, even with a downgrade solution but still no dice. I usually end up with the yellow emergency screen as a semi-brick (have to use LG phone recovery method) Not sure if if there's something I'm missing here, I'm used to the optimus 2x which never fails when flashing KDZ files. Any help would be much appreciated! Thanks (HowTos)
