Unless you also wipe internal storage, no you won't lose your personal data. When flashing a ROM you should wipe system, data, cache, and dalvik cache.

hey guys yesterday i just flashed my sensation to S-OFF and flashed the rom to leedroid 3.0 for the first time so i have a question if i want to move to another rom what i gotta do first?Just reflash the other rom?or i need to do other things before i move to the another 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

....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...
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....

If you wipe system you done loose data ... data here roughly means data partition which holds apps
it wipes only when you wipe data or a reset etc
in recovery you can make a backup of current rom ... you need abour 400 mb free space on sdcard
then try anything if it doesnt work out .. in recovery you can restore and nothing would be lost

you will loose your current rom not data ...
u see apps are in /data partition
and rom on /system ... so wiping system wont afftect /data
its like in windows when you reinstall windows ... only c: gets wiped rest like d: etc arent changed
for nandroid restore ... u can go in recovery > backup and restore ... there is an option for that

©FIRST & LAST >>WIPING/FACTORY RESETTING SYSTEM DOESN'T DELETING SYSTEM.
My dear bro.answer is very very simple
First thing- you want data but not settings right ?
Just go in recovery - go in backup section - backup whole system(do a nandroid bacup)
After that in main menu select -wipe data/factory reset and then wipe cache and dalvik cache also,Ok
Now you only want data and fresh system(resetted) am i right ?
Now go to backup &restore - select Advance restore - select restore data only - select your last backup.
After that back in main menu and select reboot system now!and voila system rebooted(takes about 5-7 minutes ) and you can seeing problem is gone and all data is intact.as it is.
Last but no least - some of your apps that you installed separately is in internal memory is gone due to factory resetting system.
So it is adviced do a titanium backup of each before doing above things
Btw,who tells you wiping system delets itself?
Press thanks if i helped you!

I would do a clean install.
-Backup user's app and data (if you want to) I use Titanium Backup but any similar app will do.
-Nandroid backup of your current ROM just in case
-Format system
-wipe data, cache and dalvik cache
-Flash ROM and Gapps
-Reboot
-Restore user's app + data
-Let Google restore any system app's data.
*If you want a totally fresh tablet you can format internal sd card (it will wipe EVERYTHING) but make sure the files you want to flash is on external micro sd card and your recovery can read from external micro sd card

I think it should be fine with that version TWRP, I'm using an older version too (I think 2.3....)
Wiping data is the same as factory reset.
I would recommend updating to TWRP 2.3.2.3 or newer. The older ones don't always work well with the multi-user file structure and you may end up with a /sdcard/0/ directory with what used to be your /sdcard/. This was fixed in 2.3.2.3.
Yeah I think that's the version I use, 2.3.2.3
Hey,
I want to do a full wipe (incl internal storage). But do I loose my TWRP then?
Thanks!
Nope. But if you do a complete wipe you'll lose everything that's on the internal SD.
No, a full wipe is wiping system, data, cache, and dalvik cache. Your internal storage isn't touched unless you specifically wipe it as well.

Are you worried about losing a TWRP backup or the actual recovery? If you wipe internal storage you'll lose everything that's on it, including any TWRP backup. But, no matter what you wipe inrecovery you'll never erase TWRP.

Week of course system files will be deleted if you do a full wipe, because a full wipe entails wiping the system partition. Exactly what are you trying to do? Are you flashing a new ROM?

No just clean up my phone by only wiping my internal storage.
