Question about wiping before loading ROMs

OK so every ROM that you want to move to requests (requires) that you wipe before you load the new ROM. That makes sense to me as you want a clean install.
My question is, what am I supposed to wipe (Sorry stupid question). I boot to recovery and I have a wipe menu and I have several options:
Wipe data/factory reset
Wipe Dalvik-cache
Wipe SD:ext partition
I have two more for wiping stats which I will make an educated guess are not required. Should I wipe everything listed above? Just dalvik cache?

Thanks! Also figured out how to clear up a problem with wiping dalvik that I had by partitioning SD card again.

If you're installing a new rom, ALWAYS do da factory reset, wipe dalvik cache and cache partition!
On the other hand, if you only want to install an "update" (new version) of the SAME ROM you already installed (MIUI for example), you don't need to do factory reset, wipe cache and dalvik cache is enough, copy and flash the updated rom and enjoy in the new version with all your data/apps/messages etc. there!

can u tell me what is stored in Dalvik cache?

if you're on stock roms, then going to cm/miui, do this:
go Recovery
-wipe dalvik cache
-wipe cache
-wipe data
-install the rom
-then it will reboot automatically(or after installation, reboot) then it will bootloop
-remove battery and put it back in, then do 3 button combo (recovery mode)
then install the rom again,
-optionally install kernels, etc
-reboot.
or if you're coming from a same rom, but new version, you don't have to wipe, just install the new version of rom.

I would recommend to never format boot, if not done correctly it may brick your phone.

Hi, I'm using nitrogen OS on my Redmi note 3. It got updated to 8.1.0(Oreo) through flashing from 8.0.0(Oreo). While doing so I didn't clear the necessary cache like dalvik, system in TWRP. Is it necessary to clear the cache in TWRP while upgrading in the android version?(Though I'm using same AOSP based nitrogen os for 8.0.0 & 8.1.0)

From what I can remember reading, when a phone boots up it makes some kind of cache of the installed applications.. it allows the phone to boot up in less time after the initial boot (in the initial boot, its making the cache that's why it takes a long time)..
When you wipe dalvik cache, this cache is deleted.. when you wipe the dalvik cache and boot you'll notice that it makes the cache again..

Extremely noob TWRP question

So I just started using TWRP and its awesome and I wanted to a simple cache partition wipe like you know the wipe cache partition on a stock recovery, so I was wondering if I should just select the Cache option in the Wipe menu or both the Cache and the Dalvik Cache?

i always wipe both, cache and dalvik - never hurts.

Thanks.

CM 12.1 Unusable

Hi everyone,
I dirty flashed gapps as I had the KitKat gapps in 12.1. Now everything constantly crashes. What would fix this?

Clear your cache & dalvik partitions in TWRP. To do this, select Wipe -> Advanced Wipe in TWRP, then check Cache & Dalvik Cache boxes, then swipe to wipe.
