Sony Experia U Locked Bootloader CWM Touch Recovery 5.5.0.4
When I do a Wipe data/Factory Reset and Wipe Delvik cache nothing seems to be wiped
I run several Root Explorers and the folders are still full of files
Delick cache is still full of .dex files
Data folder is still full of all types of files
I deleted all the files once and my phone messed up
Am I looking in the right folders
Strange thing if I don't do Wipe data/Factory reset in CWM some new roms i try don't load or work properly
When I do a backup am I doing a nandroid backup in CWM?
Thank for any help
Don't worry about no files in /data or dalvik-cache, the dalvivk is rebuilt on reboot for all installed application and data filled with factory settings and started apps prefs.
Losing all downloaded apps and having to go through setup indicates you have done factory data reset, and if you only clean dalvik you will see updating apps progress druring boot when dalvik is rebuilt.

Maybe alot of newbies ask of this already but i just wanna ask it again
What is a Full wipe is that the same as wipe?
and how do u do a full wipe properly?
Wipe
1. Wipe data/factory reset
2. Wipe Dalvik-cache
3. Wipe SD:
4. Wipe battery stats
5. Wipe rotate settings
Should i do (1.) or (1. & 2.) or (1. 2 & 3) on the amon ra boot screen
A full wipe is wiping all of those, however it is not always needed depending on whether or not you actually use Apps 2 SD etc
Most of the time you only need to wipe option 1 (with the occasional 2 as well)
2 is included by 1, for a full wipe do 1 (and 3 if you have an ext partition on your sdcard).
I've been flashing custom roms and updates for a about a month now, with once every 3 days on average. Wipe option 2 never finished successfully, and showed a message that I had to use adb to perform it or something. (not sure of the message though).
Anyway, out of no where, it worked today for the first time. I was on aHero v0.3 Rom.
What could be the reason? Is it the Rom? The only thing different I've done in this Rom was use Root Explorer.
this is a know bug in the recovery image. it tries to wipe dalvik-cache on the ext partition, which ofcourse fails if you don't have one. nevermind, the wipe works regardless of the error message.

I did partition my sd card recently but never actually made use of it. (unless some rom used it automatically) .. anyway that should explain it.
Thanks

I never get an error when I wiped mine and I don't have an ext partition
What have I done wrong
I've only ever used option 1. No issues to report here.
does Wipe SD literally deletes the content of the SD card? like formatting?
When it's recommended to use that?
no. it is called "wipe SD:ext" because it wipes only the ext partition of the sdcard. not sure what it does exactly, but i am pretty sure it just deletes the "app" and "app-private" folders on the ext partition, i have other files there that are not deleted when i wipe it.
Cool, I hope that this fixes the problems with my rom.
OK, if I understand it properly I have to lose all my apps and data to install or update a new ROM? Of course I may use Titanium backup but that is quite long process to restore all apss and data again, right?
Yes, mostly you have to wipe all. Sometimes it says that you only need to wipe cache/ dalvik cache if coming from a previous version. Do you have the free version of Titanium Backup? If you do I would suggest downloading either the paid version or MyBackup Root (it's free). Then you get one click restore. It still takes a lot of time, but you can do other stuff while it's doing it
Oh, yes, it is a good feature to restore on one click. I thought it is weird. No I understand when it is just in paid version. One more thing. Once I was restoring apps, I used app2sd script but TB restored somehow in the wrong place because the notification about low space appeared. Even though I did not get it before when I used the script. How to make sure thet TB restore apps to the right place? Thanks!!
Full wipe required?
OK, so for the RCMixHD v3.6 with Data 2 Ext(4) they say a
"Full wipe is required"
What does that mean? It is totally unclear and not being explained anywhere in the ROM tutorials. Pretty weird, because it seems rather important.
I have the ClockworkMod Recovery bootware on my HTC Desire, so how does one perform a "full wipe" without also wiping HBOOT and such (when it is S-OFF I would understand a "full wipe" actually wipes *everything* on the internal NAND/SD) ?

It's strange how both of these are rarely really required, while I STILL see this "full wipe required" being advertised for most roms. It's nonsense. Why would you need to wipe your entire SD? If a certain formatting would be required for the rom to function properly, it should include a script that does that for you and prompt before wiping your SD-card.
Also, the Factory reset is only required in very rare cases.

Well if I am updating from the same rom I will do cache and dalvik only.
When cm 7.1 hits ill do full because of updated android
Sent from my Nexus S using XDA App
Every time I flash a new ROM or restore a nandroid backup, I do the following:
1. Wipe Dalvik cache
2. Wipe data/factory reset
The second step formats /data, /cache, /sd-ext, and /sdcard/.android_secure, so that's a pretty thorough wipe if you ask me. I wipe the Dalvik cache as well to be as thorough as possible.
Optionally, you can format /system under mounts and storage in CWM recovery.
Im sorry if this is such a nooby question but on some custom roms it recommends to wipe /system. What does this do? And what do you lose? When I usually go to another rom I wipe user data, cache, dalvik cache and battery stats. I never had any problems by doing so. In my case I never saw where to wipe /system I found out it was under mounts and storage in recovery a few days ago.

This is wrong....
The /system partiton is where Android itself gets stored. As in the system apps and framework. It is recommened to wipe it when changing to a *non-wipe* firmware just in case some files are different and get left over from the previous rom.

Thanks, that makes sense.
not wiping before installing a new rom usually results to bootloops.
i see to it i wipe before installing another rom (unless i'm installing a newer version of the existing rom)

As was posted earlier in the thread, wiping system basically wipes the rom/os and system settings. Your user data, apps, pictures will not be wiped. If you rebooted after wiping system the phone will not work, however you could wipe system then flash an update of the same rom and reboot and you should be fine(depending on the changes between rom versions). This is basically referred to as dirty flashing. FYI, most custom roms have a script which wipes system, cache and dalvik/art cache automatically preserving only /data(user apps and data)
Front to Back or Back to Front & Toilet Paper or Wet Wipes? Just Kidding!
When wiping via Factory Reset in TWRP what is the best way to insure everything is getting fully wiped except our external SD card. After I did a factory reset there was still everything on the internal sd card. Do any of you use the superwipe.zip?
What Procedures do you follow when switching Roms?

Factory reset wipes /data and /cache
after Factory reset, wipe System and you should be good to go on a new or fresh installation from zip. i dont think wiping boot is necessary but you can. so do
Factory Reset
System
Boot
Dalvik-cache is in /data so you dont have to wipe that.

This is the best, and also the quickest way.
Thanks for the help... I just don't understand why I have the following on my phone.
Sdcard - I understand that this is internal.
Sdcard2
Sd-ext.
Both the sdcard2 and Sd-ext have the same files on them, it has my music, some apk files, and my flash zip files. Now my poweramp player shows duplicate albums for all of my music stored on my external sd.
Any ideas

Sd-ext is or was the best way to move apps to the sd card. But with the new OS it isn't required if the app is made right

I factory reset twice, wipe dalvik twice and wipe system twice. I don't wipe cache since the factory reset does it.
Now that it was clarified dalvik is wiped with the factory reset I'll probably stop doing that. I just wish it clarified it since it specifically indicates the cache was wiped.

I'm on checkrom and i've downloaded an MIUI theme from the kitchenpro app. I've applied it and now it's just stuck on the boot screen!
Factory reset is not an option either please!
u can at first just get into recovery and wipe cache and dalvik cache then reboot, if it presists u have only one choice left ( wipe data/factory reset from recovery)
before doing that u can make a nandroid backup to avoid loosing all your apps ( which u can select what to restore from it later using CWM,i mean for example u can only restore the /data partition )
note:u can extract the back files using root exeplorer
just wipe ur data/factory reset and cache and make a clean install of ur rom again
sorry for that , but apperantely u might have corrupted something in /system and now it's a must to wipe data/factory reset
I have a quick question regarding TWRP. I have installed a rom that i'd like to not use anymore. However, when I restore, all the system files are still there (I know this because they still pop up as a deodexed version.)
Anyways, I was wondering if it is ok to do this in TWRP
-Wipe cache/factory reset
-Wipe system data <--- that is what 'm really wondering
-Restore from my backup that I made that has the proper system files I want.
Im looking at it right now and factory reset says wipe data and cache, so I am guessing that option kills two of the 3 standard steps apart from wiping dalvik. Now the wipe system, Im not sure; but for wiping the normal 3- do factory reset, cache, and dalvik cache
All wiping or formatting /system does is wipe your current rom. I always do it before flashing or restoring anything just to be totally sure no lingering remnants of my previous rom remain and I've never had any issues doing so.

Wiping system before flashing a ROM is likely pointless, unless the ROM has a poor updater script that doesn't format system in the flash process. If it didn't format, the install would end with an error. If it was just deleting recursively and came upon a file it couldn't delete, it'd still end with an error. Formatting it before flashing isn't going to wipe anything out that wasn't already getting deleted as part of the updater-script formatting/deleting.
Also, if you perform a factory reset in recovery, you don't then have to go and wipe cache and dalvik cache as well. Factory reset already formats all three of those. Wiping cache also clears out the dalvik cache, since that is where the dalvik cache resides. Wiping 3 times is also a waste of time, as again, do you expect things to be left behind when it is formatted?
Do people frequently experience files being left over on flash drives and other removable storage devices when they format them that this whole "lets format it 3 times to make sure it's gone" craze started? Every time I've ever formatted something, as long as the process completed successfully, all the files were gone. The same goes for deleting a bunch of folders. As long as there wasn't an error, all those files disappeared too.
