What is the difference between clearing partition cache in recovery and going through the individual cache apps? I just deleted about 1gb of app cache. Will I achieve anything else if I go through the recovery? I'm assuming I wont lose any pictures or any personal data?

Does selecting the "wipe data" via clockworkmod recovery also wipes my stored pictures and music or does it only wipe all the OS data?

Nothing will wipe your stored pictures / music or SD card unless you partition your SD card.
Wiping factory settings is the ONLY one that would wipe your OS data.
If you want a full wipe.. wipe dalvik / factory / cache.
Wiping dalvik / cache won't do anything but if you're experiencing slowness, wipe those.. you dont really lose anything
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....
I'm in the habit of installing Carbon Nightlies. Most of the time its everyday or every other day. I always wipe Delvik cache and Cache before I install. I was wondering if all this cache i delete, is essential for saving data, because I have a data cap. Or do I not know what I'm talking about?

first off, when you flash a rom it automatically wipes your dalvik and cache, so you wiping it again is pointless. and it has nothing to do with your data cap. your dalvik rebuilds when booting up, hense the android is upgrading. and you fill up the apps cache as you use your apps.

Thanks. So when I flash the nightly it automatically wipes the cache. Does it wipe cache in apps, for instance, like Chrome browser?

yup, when you flash, the cache is automatically wiped(the app cache is what gets wiped when you manually wipe cache as well).

Am I being anal. Because now I have to rebuild the cache i normally built over time by manually going to the websites I frequently visit..Thus using more data. Compared to never flashing again\never wiping cache again. Or is it such a miniscule amount of data that I won't notices the MBs on my bill

it usually is just tiny bit of data, but i understand the being anal part. going to your websites would probably use more data. plus, most of that data in the cache isnt data you download, but data the comes up just from use of the apps.
