what does LMC and MGC mean?If you want to get LMC I would just get the latest, LMC8.4_R14.
That is what I run for LMC on my A52s. LMC has really improved on A52s in the last few months, no more hangs (after proper configuration) and properly working night mode.
Probably this advice still works:
Settings|System Settings|Stream Configuration|Stream Configuration section|Change all the values to 61448-EISV3, except Video set that to '0-default'.
But I would not know for sure because I use LMC8.4_A52s_Metal.xml that works out of the box (that is a Telegram link, and you have to put the file in an LMC8.4 top level directory and then double tap next to the shutter button to load it).
I have LMC installed, but I still take almost all of my photos with MGC 8.1.
