Usually when installing roms, in the instructions you're told to wipe data, and then dalvik cache.
As far as I'm aware, since dalvik cache is IN /data it's wiped when data is wiped. So why is it a separate instruction?

I am too having the same question!!
All stock roms and some custom roms (depends on developers) have .odex files in for all app and framework files(inside system) these are files which contains some information about those apks and jar files and these odex files are written in dalvik partition and run at the boot and make boot faster. When you install a new rom these must be wiped since it is a part of the old rom

thanks for your time!
All you need to do is wipe your data and wipe the cache.
and Flash the other ROM's zip file!!
wipe my data?with super wipe you meant?
and for real?
I´ve made a nandroid and then I do a Full Wipe.
wipe data, cache, AND dalvik cache in recovery
make a Nandroid backup first, Then wipe data, cache, Dav cache etc..there are many good tutorials on this site to help you on this... good luck!
From RECOVERY: Make a Nandroid Backup, wipe data, wipe cache, wipe Dalvik cache, and from there you can flash whatever ROM you want from your SD CARD.
Also i found that using ROM Manager, you can do a backup (like Nandroid Backup), it saves the files on the SD CARD and you can also copy the file to your computer (in case your something happens to your SD CARD for example), and whenever you want if you don't like the new ROM that you just installed or you are having problems with it, you can restore your previous ROM.
I've been using for some time now LeeDrOiD HD V3.3.3-Port-R5 Ginger Sense 2.1 and it's great.
Why wipe cache and dalvik as well? You guys realise dalvik cache is stored in the cache partition?

you don't have to wipe dalvik cache if you don't want to... you will just have to deal with any problems you run into

those 2 are to to wipe the phone previus a theme install. it will NOT erase your apps DATA wipe or Factory reset will erase everything including apps.
i wipped those 2 always before installing a new theme or a rom based on my same android version (2.3.5) and my apps and google accounts are always there in my new room like they were before

The app cache will be rebuild when the apps start the next time.
The dalvik-cache will be rebuild on reboot.
You might get some FCs until you rebooted, after you wiped the dalvik-cache.
tl:dr there is no correct order.
Hi all,
I have a quick question. What do all the wipes in ClockWorkMod actually wipe?Specifically, what do the following actually wipe?
- wipe data/factory reset?
- wipe cache partition?
- wipe Dalvik Cache?
I did do a search, and have installed many roms, and although I follow all the instructions, I have never known what these actually do.
Wipe data means your ROM setting and date and time such things will be deleted
Wipe cache means wiping the cache of user and system apps.for every application it allocate some space for cache that well be removed
Wipe dalvic cache is wiping compilation cache.in Android having a dalvic compiler.
Hope you get it...this is what i know about this
Xperian8~ click thanks if it helps...
Wiping data means deleting all the apps unrelated to system application, and in addition, it also deletes most the saved data for all applications (from /data/data) folder.
Wiping cache means deleting all those files left by installation process or any other temporary mean. In general it is safe to do so without getting anything reset.
Wiping dalvik cache (/data/dalvik-cache) means deleting all the cached files generated by compiler. In general it is safe to do so without getting anything reset. This is also epic useful when you face force close error. It may have something to do with the dalvik cache.
Is wipe data and factory reset the same?
I see a lot of roms say wipe cache, wipe data, and wipe dalvik cache. In TWRP on my Note 2, I see wipe cache and dalvik cache but not data. Is wiping data the same as factory reset? If not should I just ignore "wipe data"?
So, we all know how to flash a ROM and the various steps you should do to ensure a clean install.
Dalvik, cache, data, and system should be wiped. Minus factory reset (which does data and system) for updated builds of a ROM.
My question, which was prompted by installing Google Now, is what do each of these things actually do? It would be useful for example to know if I should clean the Dalvik cache when trying to install a less buggy version of the app, but as I have no idea what Dalvik is I have no way of knowing.
Would any knowledgeable person like to quickly break down what clearing the cache, data, system and Dalvik do?

yes whenever you install a new ROM its better to have a good clean up before doing so...
factory rest will format or wipe cache and data...dalvik is inside cache so no need to do it again..the same for battery stats...format system is clearly just wiping system partition clean
....to wipe unneeded files in the dalvik cache, and so they will add up over time and take a lot of space and make the phone slower? Therefore it is a MUST to root one's phone?
Is that a correct assumption?
Thanks!
Try it. Use any file manager, go to /cache/dalvik-cache, and delete something, or everything.
The reason why it is called a cache is to speed up the phone.
It won't take up memory because of the way the phones storage is partitioned.

For formating caches you could use file manager but it also need root permission...
And until you flash other custom rom you need not to wipe cache...
Apps cache is being created for the first time you boot your phone for better application launch...
So if you got a serious problem of force crash on stock rom, please do full reset...

You can use Factory Reset from Settings menu.

Guys, please read the original post.
Anyway, I tried unrooting my phone and deleting contents of dalvik cache. As expected, this is what happened:
1. Using ES File Explorer, WAS NOT ABLE to access the /data/dalvik-cache folder. It showed "Empty folder" or something like that.
2. Using Root Explorer, message that read "You're phone doesn't seem to be rooted, etc. etc. " (cannot access folder also)
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
So here's my new set of questions:
1. Does factory reset erase dalvik-cache? (I would assume so)
2. If phone is unrooted, dalvik cache contents cannot be accessed or deleted (as I have proven). Does that mean they will add up over time (unless you factory reset the phone??) and cause problems like making the phone slower?
Hope that's clear.
Thanks!!!
What phone are you using? If for samsung, you can still wipe that in stock recovery even if you are unrooted...
Dalvik cache is in your /data partition, so yeah, it will be erased if you factory reset...your phone should manage dalvik by itself, it should not build up (except if you mess with it), so don't worry...
Ryuinferno, hello. I'm using Samsung Galaxy Ace. So how do I wipe the dalvik cache in stock recovery of unrooted phone? Are you referring to factory reset / data wipe? I know that already. I know that already. If you're referring to something else, please let me know.
Are you sure android phones manage the dalvik cache by themselves? Because sometimes when I uninstall an app, a related file would still be left in dalvik. I would then manually delete it or delete it using Titanium Backup. Also, why does Titanium Backup have an option to "Clean up the Dalvik cache..." if the phone manages it by itself?
Thanks!!!

Even wiping dalvik cache will cause apps to misbehave in you don't factory reset ...
If you are rooted , it will also have same effect ...
So do factory reset if you are in stock ROM and full wipe if you are on custom ROM ...

Hmm...I can't remember too well as I left stock recovery too long...never left my phone unrooted......I think there is a wipe cache option in stock recovery but I am not sure whether will it wipe dalvik or not...
Titanium backup has an option to wipe dalvik because when changing ROMs/restoring apps, the current dalvik may be conflicting with the newly restored app...that is why you need to rebuild them...usually the old unused dalvik should be cleared upon a reboot...
"Hmm...I can't remember too well as I left stock recovery too long...never left my phone unrooted......I think there is a wipe cache option in stock recovery but I am not sure whether will it wipe dalvik or not..."
Maybe not? Because wipe cache and wipe dalvik cache are two separate options in ClockworkMOD Recovery, is it not? Or maybe in stock recovery, it DOES wipe dalvik as well....
