how to wipe properly

I did not find similar threads on this so im going to say it for the final time....
Wiping by factory reset, wipe cache,dalvik cache and wiping battery stats is not wiping properly!!!
To install a rom freshly you wipe with the following correct procedures:
1.format system
2.format data
3.format cache
no need to wipe anything else. This is how u wipe properly before installling a rom. not by factory resetting by THIS.
Hope i helped many

It would be good to note that the factory reset option in CWM does this. The one in the actual ROM I'm not sure of, but it probably doesn't.

Select “wipe data/factory reset
Select “yes”

This guide is not proper

full wipe / changing roms:
1. wipe data/factory reset (this formats /data, /cache and .android_secure on sd)
2. format /system, /boot
this leaves you with a "virgin" phone, only bootloader, recovery and radio are left. dalvik-cache resides on /data, so it's gone already.
3. flash rom
4. optional: gapps & custom-kernel. no need to let the phone boot & settle before flashing them.
5. reboot
just updating rom:
1. flash rom-zip
2. wipe /cache and dalvik-cache
3. reboot
optional: if using a custom-kernel, flash it again after rom-zip. most custom-kernels have a script that automatically wipes /cache & dalvik during kernel-install.

TWRP Wipe

What is considered a full wipe in TWRP? Do I wipe cache, dalvik, & factory reset? Do I also need to format system?

Cache, dalvik, and factory reset is good. System should automatically be wiped when flashing the new ROM. But you can wipe system yourself, won't hurt. Always have a backup, too, JIC.

[Q] Can Wifi get affected, if you don't wipe Dalvik Cache

I have flashed a CM 10.1 ROM on my Galaxy S advance. I am using CWM 6, I diid wipe data/factory reset and wipe cache, and installed ZIP from SDcard and installed Gapps for 4.2.2 and then rebooted. WIFI is not listing the networks and I have to add my AP settings manually.
Does this behavior is attributed to not wiping Dalvik Cache.. ?

[Q] E:Unable to mount /system [SULTAN]

Hi guys.
I wiped data, cache, delvik.
I flashed latest stable CM
I flashed Gapps Pico
I booted once
I rebooted into recovery TWRP 2.8.6.0
I then wiped date, cache, delvik again.
I then tried to install SULTAN 5.1.1 ROM
Getting E:Unable to mount /System
Why is this?
Stuck on this screen, waiting for any reply
Thank you!

I think you have to wipe /system too before you flash ROM.
Here are his instructions:
Next, download and flash the latest official CM12.1 snapshot. Then, without rebooting from recovery, wipe /system and flash my ROM. This process is necessary to update various firmwares (including TrustZone), as the updated firmware is needed by my ROM. After flashing my ROM, flash a Google apps package, and then reboot.

TWRP no option to wipe cache

Somebody also noticed that there's no option in official twrp to only wipe cache?

there is on mine. but everytime i wipe cache , the logs says "cache is not mounted".
[Edited]
Nope , just checked it, and its just shows "Dalvik / Art Cache" . i just realized it

Yupp. Even in stock recovery was the option to wipe only the cache. Weird... Is there any other way to wipe the cache?
Btw, I pulled up an issue request on GitHub. https://github.com/TeamWin/Team-Win-Recovery-Project/issues/1254

I think it's relevant with that slot a/b thing(?)
how about in the unofficial of twrp?

you have to use stock boot.img and wipe cache in recovery.
after a ROM update go into recovery and wipe cache before installing TWRP / Kernel / Magisk
otherwise no way.
