LAF - Get Physical dump from LAF
The LAF method works on all LG smartphones with the new version of the LG LAF protocol (this is a service download mode similar to the Samsung Odin download mode). Every LG smartphone from the year 2013 and newer should therefore support our LAF method, but it varies by version of Android OS. This exploit takes advantage of "LG Flash Mode", and is used primarily for updating firmware.
There is a way that you may be able to extract a physical image from LG phones without root access (rooting the phone).
Please also take in to account storage memory encryption.
