LGUP is the latest software update flashing tool for the LG devices. It can be used to flash complete firmware packages and restore LG device to complete stock. These firmware files, usually come in .KDZ, DZ and .TOT extensions which require a special tool like LGUP to read and write. Earlier, we have shared several posts on rooting the LG devices. However, sometimes, it’s better to revert back to the official firmware update in order to receive official OTA updates. Moreover, the official firmware is stable and battery efficient.

Though LGUP has been updated several times, it still has some bugs. The most annoying one is with the detection of LG device when connected via USB cable to PC. This is very important part while flashing the full stock firmware. The tool sometimes fails to detect LG device and the specific model of the phone. This is where uppercut comes into action. It auto-detects the LG device and model number.
