LG Stylo 6 firmware download & software update lm-q730 stock ROM

There are 2 ways to update the LG Stylo 6 firmware. The easier and preferable method is via the update center. We need to download the OTA update and install it without connecting the phone to the computer.

In the second method, we need to download the stock firmware file and flash it using the LGUP flash tool via Download Mode. This method is useful in restoring a bricked or dead phone. If your LG Stylo 6 is stuck on the boot screen or in a boot loop, you can flash the Stock ROM kdz file to restore it back to the working state.

Let’s check out both the methods in great detail with the help of the below screenshots –
