Download Verizon LG V20 VS995 DLL – LG UP DLL for LG V20 VS995
LG UP is LG’s new tool which can be used to flash TOT OR KDZ format firmware. The LG UP DLL is important, without the DLL file, the LG UP software can not detect your phone model number and current software version.
To unbrick/Restore LG VS20 VS995, You need to isntall latest LG USB drivers, LG UP DLL FOR VS995 and LG UP Software.
You need to download both LGUP_VS995.msi and LGUP_VS995C.msi from above links, I am not sure which one works. Please install LGUP_VS995.msi first, if it does not work, please uninstall the LGUP_VS995.msi completely from control panel and then install the LGUP_VS995C.msi.
Wish this helps.
