What to wipe when flashing custom rom?

[JohnnyDanger]

Hello all. I know this is a noob question and Im sorry, but I need to ask.

When Im flashing a custom rom (going to try EOS again) what exactly do I need to wipe?

Im using TWRP. I know that I need to wipe the Cache, Dalvik Cache and system. Do I also choose the Factory Reset option? How about Internal Storage? Then there is the Format Data option. Which of these should I do?

If you do a factory reset, you don't have to worry about wiping anything else.

As for what to wipe for installing a custom ROM, it depends. EOS recommends a factory reset when you are flashing their ROMs going from any other type of ROM, including stock. If your on ICS, to jellybean, factory reset. 4.1 to 4.2, factory reset. One nightly to the newer one, you don't have too.

Internal storage is not something you want to wipe... that is any pictures, files, music etc. etc. that you have on the tablet, it will be the same as when you unlock the bootloader, you lose EVERYTHING!! Factory reset, you won't lose anything that isn't on the system partition.

Make sure you are on the latest version of the recommended recoveries
