V30B 降不了5.0

1. Use LGUP HERE to flash a previous KDZ version. The LGUP thread assumes you have a G4... so instead of downloading the "8992 DLL use the DLL installer LGUP_8974_DLL_Ver_0_5_CODEFIRE.MSI HERE instead.

2. Restore your TWRP backups. Depending on your TWRP build it may or may not backup modem. If it does not and you flashed the 30B modem you will have to find a Lollipop modem zip elsewhere. All versions of TWRP should backup Boot, system and data.. so only other variable is modem/rpm/tz.

3. Use LG Flash + TOT + NEW DLL HERE to downgrade. I think LGUP is the better option tho... LGUP can flash both KDZ and TOT and doesn"t care which COM port it"s using.
