LGUP Upgrade vs Refurbish?
1) REFURBISH： You will lose all user data（KDZ or TOT）
2) UPGRADE: Keep data and update your phone（KDZ or TOT）
Select Upgrade to flash kdz firmware to unbrick/restore your phone back to stock.
3) ChipErase: Dangerous, This will erase IMEI/efs, Do not try this if you do not have an NV backup.
Chip Erase can also remove the Google FRP on many LG devices with Android 5.0, 6.0. (Such as LG H345, LG MS345)
4)PARTITION DL：flash the single Partition or selected partitions onto your phone.
This feature can solve “unknown model” issues. This feature can be used to bypass Google FRP by flashing specific tot firmware.
5)DUMP：Dump all partitions of your phone as backup.,
AT&T and Spring LG phone users may need this feature to dump the firmware from a working phone as back up and use “Partition DL” to restore phones.,Because AT&T and Sprint LG devices support Software Update OTA only, there is no way to download stock kdz firmware for AT&T and Sprint LG devices.
6) FOTA Upgrade: This can be used to flash the OTA Update file that comes with dot up file extension.
LG up1.14 patched works on LG V30, LG V35, LG G6, and G7
