Any rom worth a dam will have the system and boot wipe in the script.

[GUIDE] Proper FULL wipe
- Thread starter obsanity
- Start date
In the past I have always performed these steps in this order:
wipe data/factory reset
wipe cache partition
in advanced: wipe dalvik cache
in mounts and storage: format /system /data /cache /boot
vs
wipe data/factory reset
format /system
format /boot
Have I been duplicating processes that are accomplished with just these three steps? How important is the order of the steps?
wipe data/factory reset
wipe cache partition
in advanced: wipe dalvik cache
in mounts and storage: format /system /data /cache /boot
vs
wipe data/factory reset
format /system
format /boot

Yes you have been. Cache and dalvik are wiped during the factory reset option. The order of these steps are important but what you've been doing so far is correct outside the duplicated steps.
No not by default. Its up to the developer of the ROM to clean what they think should be cleaned. However, many, including CyanogenMod do not. I actually believe its bad practice since this step doesn't need to be performed unless you are beta testing roms.
you should add this to OP:

Yeah AllGamer moved it and said it was "common knowledge". All I can do is keep it in my signature.
It is in the right place. He is not developing anything. And as said, it is pretty common knowledge.

Perhaps it's common knowledge for the more expert XDA users, but alot of us just barely got the fundamentels of flashing roms.
For that I'd love to know the proper wiping needed to flashing a rom/kernel
(It's always different in different guides)
Basicly this full wipe is the best for flashing a rom?

Well, it IS common knowledge that 90% of issues posted about in development threads are related to improper flashing methods. I guess it makes sense to keep that going strong.
Thanks allgamer! You're a gentleman and a scholar.

This is definitely not common knowledge. Thank you for the post.
Most instructions I see are to do the following (with some slight variations):
Wipe Data/factory reset
Wipe Cache
Wipe Dalvik-Cache
Many of the custom roms that I've seen don't do a "full wipe", such as the current version CheckROM.
Here's another opinion on the correct way to do a full wipe:
http://checkrom.com/threads/full-wipe-the-correct-way.432/
There are similarities between the instructions here and the instructions from spider (both format /system), but there are differences. obsanity, what do you think of spider's method?

Just to confirm, the /efs partition is safe unless you were to do something silly like "format /efs", right?

43I know this is not a development thread but I must insist we have something like this in this area. I would ask a mod to keep this sticky or maybe link to it from another sticky thread. I feel it's important to all development for accurate results and debug information.
I see this all the time. People think they are fully wiping when a developer asks for it. I believe that some people still don't understand what a full wipe is because there is no such single option in ClockWorkMod Recovery. Most likely the reason for that is because Koush didn't want too many posts about "I'm stuck on Google logo" or "my phone won't boot". So here is a test you can do yourself: Backup your ROM of course, and then do a full wipe. Then don't install anything and just reboot. If you end up pass the Google logo and onto the boot loop screen, then what you think is a full wipe is incorrect. If you are stuck on the Google logo and nothing is happening however, then congratulations... you know what you're doing
For the rest of you, here are proper steps to fully wipe without leaving any trace of ROM on your phone:
- wipe data/factory reset
- format /system
- format /boot
Now most people think that the first option is enough. That may often be the case but because the developer can drastically change the contents of the /system folder, things can get messed up if you don't format it. And guess what, that first option will not do it. Wipe data/factory reset only wipes the /data folder which contains your personal settings and all the apps you installed. The ROM is then left blank as if you just flashed it and you can start over. FYI, the format of boot partition simply wipes the boot animation and you can restore it using the advance option in recovery from ROM to another.
I've seen some zip files which do this automatically so that's fine but at least you know what needs to be done to fully wipe.
There you go. I hope this clears some things. Now lets flash some ROMs!3
In TWRP 2.3.3
Dalvik, Factory Reset (includes Data, Cache), System, Android Secure
:cyclops:2all we need is a zip that does all of that and were good!!
