So far I have managed to root, install TWRP, and flashed the OptimusDE Rom. Like it, been using it a couple days.
My question is regarding trying a different ROM. I have done a back up, both of my original setup as well as the DE rom I have tweaked a bit and been using. Figured out how to back up, restore etc.
I want to flash a different rom to try out, however a bit nervous about what data to wipe prior to install via TWRP.
I believe from what I have read I should wipe everything except internal storage, however I would prefer to ask here before deleting all files and needing to learn about sideload or USB loading.. My back ups are in my TWRP folder, and my roms in the Download folder. (Also backed up to PC)
Also following the install do I wipe cache before reboot?
