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.

A noob question..please help

I searched alooot..but didn't find an answer!
I am about to install the broadrom on my i9001..
The problem is its asking to format all the partitions in the CWM..
How can I do this the right way??
I have CMW installed..

Go to mounts and storage, there u can see all the partitions.. the last 4 say: Format /xxx do that will all the partitions!

thanks bro..

it says that I can just wipe the dalvik code..

davlik cache is just a temporary cache for all apps, this can be wiped at all times, it will take about 1.5 min to boot after dalvik is cleared.

Do you mean - before flashing CM9, you have to wipe all data?
Or do you mean - flashing back to Samsung rom and then all the way back to CM9?
For me, a clean install would be, download the CM9 .zip file, go to recovery, wipe data/factory reset and then flash the new rom.
(Be careful, as clean means all your user data as settings and apps get deleted)
Cheers

[Q] wipe cache and data?

hello there!
i'm a new little fellah in the rom flashing world, so i'm a little afraid before doing anything, so here's the situation :
i have a galaxy mini, rooted, and cwm is perfectly installed.
i want to install this rom : http://forum.xda-developers.com/showthread.php?t=2085347
In the description it's written to wipe data AND cache after every action.
I just have personally 2 thing to install : the rom and the gapps, that's all (no patch).
So i have to wipe cache and data before flashing the rom of course, and so my question is : do i have to wipe data AND cache after installing the rom? and then install the gapps, and then wipe again?
So should i do :
1) wipe data and cache
2) install from zip the rom
3) wipe data and cache
4) install from zip the gapps
5) wipe data and cache
6) reboot
Is that good? or am i doing a mistake anywhere?
thank you for your help !

normally this works
wipe data ,cache and dalvik cache
format system ( if going from stock to cm7 or vice versa)
install rom
install gapps
wipe data , cache
reboot

you can also wipe battery states but it's only optional, you dont have to but no harm in doing so.

When you flash another rom I recommend wiping: Data, Cache, Dalvik Cache and System.
when you flash an update for that rom: wipe Cache and Dalvik Cache, Install update.
Stepts of installing a new rom:
1) Put the rom and gapps on your device
2)Wipe Data, Cache, Dalvik Cache and System
3)Flash the system and then the gapps
4)Reboot
Stepts of installing an update for the rom:
1)Put the updated file on your device
2)Wipe Cache and Dalvik Cache
3)Install updates
4)Reboot

thank u so much for ur best explanation:good::good:
