I dont know wich rom caused it but...
My storage is now:
storage/emulated/o/o/o/o....
why do i have all those O folders?
The only thing in it is another O folder!
Somehow it got like this, i cant remember when.
How to change to normal?
Can i complete wipe/format when i am in recovery on a installed rom?
From costom recovery wipe internal storage. ... (it deletes everything so backup important data before wipe) wipe cache, delvic cache and boot up

hi,
I had so much stuff on the tablet I decided to reinstall rom...
performed factory reset, wiped cache partition, & installed ics rom again and to my surprise all my data was there.
what else needs to be whiped to delete all wanted and unwanted data?
thanks
You can delete all the stuff from /data/media - its mounted as sdcard - its the content that you see when you are connected via usb. Dont worry, all directories will be created new when you flash the rom again. You can also format the system partition in recovery. Put the rom to your empty data/media directory before you do this and install with choose from zip...
Hi guys, I've been flashing my new Galaxy S3 lately and have started to migrate my music library onto my internal 32GB. It's a healthy 15GB of music.
I run SynergyROM r66, and would like to load up r71 fairly soon, bu would not like to lose my music, as it is a pain to resync for me.
How do I do so without it reformatting my internal memory? I'm sticking with Synergy so I don't think I need to do a "clean wipe" right?
Is it as simple as Wipe Cache/Wipe Dalvik, then Install from SD, then reboot? No factory reset?
Any help is appreciated, thank you.

data wipe/ factory reset from stock recovery formats internal memory. data/wipe factory reset from Cwm recovery only wipes system data and does not reformat internal sd, unless you manually do it thru mounts/storage menu in cwm...although you should be fine with just a cache wipe going to r71.

Cool, what about the Dalvik cache, what does that do?

The Dalvik virtual machine deals with your apps. Whenever changing apps it's a good idea to clear it's cache so you don't have cached data for a different version of an app - this could confuse the machine and lead to problems.
Perfect. thanks for the help guys.
Wiping through cwm recovery in recovery (not the app itself) will not wipe your media or pictures or downloaded files etc. Your Music will be intact, but something not mentioned here yet, do you have an external sd card? Always a good idea to put that important stuff on it,or at least copies of it to be safe, including titanium backups. Though cwm won't wipe your media, if something goes wrong and you have to do a stock recovery, you may forget that cwm is NO LONGER there, and accidentally wipe your media like I did once bricking my galaxy player 5.0!

Yea, I got it all backed up to one of the Hard Drives on my computer. This should go smoothly.
....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....
Using android for last 3 years but it has to be the worst day today. Wanted to upgrade rom. Went to recovery (TWRP) and then selected wipe> cache, delvik cache and format data. Bang it has removed all what I had in the internal storage. What the F is that. Now if I go to install, it doesn't show any folder in sdcard
I have only 1 question, can I get back all my data??? I had vcf files, TB data and sms data I will throw my phone away How can I make such a big mistake. I made efs backup but it doesn't exist too. I always used CWm recovery and it never formated whole sd card when I selected format data, how can this recovery do. Please Please help me

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
