[Q] Wiping Cache from Recovery? *PLEASE HELP*

Upon booting up via Vol. Down + Power, there are four options (fastboot, recovery, wipe cache, and simunlock). What happens when you wipe cache?
I just installed a new ROM (well updated), couldnt get it to boot as I was stuck on the custom boot screen, but after wipe cache it loads up?
Does this effect the functionality at all? Please help. Thanks

I believe this is a factory wipe, but is a dumbed down version, that does not wipe /sd-ext partitions etc. Just removes /data programs and user info, but won't touch any /system applications.
It is used to reset the phone without actually booting up the OS

Any particular reason why my ROM wouldnt boot up normally but requires a cache wipe in order to boot?

Soms roms will require you to wipe dalvik cache in order for the new rom to boot (conflicts can be caused), and wiping this cache would do it, however you can just wipe dalvik cache from recovery not this hboot menu.
For future reference when changing roms, especially when changing to someone elses rom (and especially especially when its a different base) you should be doing a full wipe
A full wipe is:
-Data (factory reset)
-Dalvik Cache
-Ext partition (although sometimes you can get away with skipping this one)
You should be able to wipe those three from both Amon-RA and Clockwork Mod recoveries.

NOTE: I am sleep deprived, so this will proberly not make alot of sense
I'm not that technical with the Android system (have worked with linux abit though)
Deleting the cache would remove any saved data from the system. These saved items may contain anything from images to which default program is loaded, to which widgets are loaded on the homscreen.
This is why after a new install the phone takes a little longer booting up, creating all the new files. If you need me to go into cache, use Google.
Another theory would be:
After an upgrade, some files and apps think that the system has changed owners, so their permissions change from read/write to read/only etc.
With this, some system files will become inaccessible, will be unable to be edited and so forth.
A way around this would be to "fix" the permissions of the data, changing the owner of the files allowing read/write permissions
Rom Manager has a nice little feature that allows you to fix permissions, and has come very helpful for me, with my switching to and from OD/Pinky, and restoring LauncherPro, which likes to FC at every restore -.-.

[Q] Wiping Dalvik

When reboot my phone and go into Clockwork Recovery to install a new ROM, i do a 2x Wipe of data and then 1x Cache Wipe and 1x Dalvik, but the Dalvik does not do anything, i hit the power button and try to run it and nothing happens, no words scroll saying wipe complete or anything...
Please Help
Im running Ava v6
Thanks

I'll be polite: This has been discussed a number of times. Search first, ask questions later.

I found this in a thread, It was a post from you.
Thanks

ClockworkMod DOES indeed wipe the dalvik cache. I think the reason why many people are confused is that it only takes a second or two for the dalvik cache to wipe on CWM, whereas it takes longer on RA. However, the reasoning behind this is simple- most people wipe the cache partition before wiping the dalvik cache. When you wipe the cache partition, you are wiping everything on that partition, including the dalvik cache. So in essence, when people go to the Advanced menu in CWM to directly wipe the dalvik cache, they are essentially wiping a blank folder.
If you don't believe me, try this:
1. Reboot into recovery
2. Go to the CWM partitions menu and mount the cache partition
3. adb shell
4. cd /cache/dalvik-cache
5. Type "ls-a" and note all the files.
6. Exit adb shell
7. Wipe the cache partition in CWM
8. adb shell
9. cd /cache
10. Type "ls-a". This time there should be no dalvik-cache directory.
I posted this exact test and result a couple of weeks ago, with the same reasoning. People don't care, they believe what they want to believe.
It would be at least compelling if somebody from the other camp would post proof that CWM does NOT wipe their dalvik cache.

Actually, just the response at the bottom was mine, but yeah, now you know. The answer is still somewhat unclear. I would assume it's working (since you are wiping /data anyway . . . twice, because you're OCD or something ) unless you have problems. Some say it works fine, some say it doesn't, but I haven't seen anything beyond the "there are reports that it doesn't" thing - it's always a friend of a friend.

[Q] Complete Wipe?

Ok, I don't know what I'm doing wrong, but I can never get rid of stuff completely.... like my Gapps are still there after everything and all I install is CM
I tried:
Wipe data/user settings
Wipe Cache
Wipe Davlik Cache
I also tried:
Wipe data/user settings
Wipe Cache
Wipe Davlik Cache
Format Data (in Partitions)
Format Cache (in Partitions)
Format Boot (in Partitions)
Format System (in Partitions)
I have tried both these options and I am still left with remnants of previous ROMs. Any suggestions? Do I have to load PC36IMG.zip and then root everytime to have a clean install? Seems a little extreme...

Clockwork 2.5 (previously), but I just switched to RA Recovery v2.2.2 still have Gapps on my phone... CM doesn't include Gapps right? I remember having to install them before unless something changed

Can't get rid of gapps, dude. CM requires it that they be there so they're protected files that you can't erase (unless you flash a new rom, which has all the gapps built in anyway).
I hope you like Google programs, because you are stuck with em

I love Gapps! I just suspect some of my FCs is because I had an older version of them. I am running CM7 now and I have the new GB Gapps but I thought it was odd that Gmail, Maps, etc was still on there before I even flashed the new Gapps
So to answer my original question, there is no way to completely wipe short of reimaging with PC36IMG and rooting again?

Run FORMAT_ALL from the post below. Once its down booting your new install, do not put your information into the setup wizard (just keep hitting skip). This will get you a clean install. REMEMBER FORMAT ALL WILL ERASE EVERYTHING ON YOUR PHONE (not sdcard/recovery/boot/s-off).

I'll give it a go, but according to Caulkin's thread all it is doing is what I did already! (wipe data, cache & format boot/system) I will try it out though. Thanks!
I did never try skipping the setup wizard... Hmm

This is the key, it will not restore the old apps, if you skip the wizard.

Well, I did it! Yippee!
I did the following this time around:
Wipe data/user settings
Wipe cache
Wipe Davlik cache
Ran Caulkin's Format_all.zip
Installed CM7 nightly
Funny thing is, it bypassed the setup altogether... I'm guessing because Gapps were finally gone! It brought me right to the home screen, I opened up apps and no Gmail, no Market, nothing! Finally!
So I rebooted Recovery, installed GB Gapps and I am running smooth as butter (No FCs yet!)
Thanks everyone! Especially bwcorvis for the link to Caulkin's script

Glad i could help

Dalvik cache clearing problem

I'm trying out a few ROMs today but now I think I cannot clear the dalvik cache.
In recovery, when I go to advanced -> wipe dalvik cache it says
E:unknown volume for path [/sd-ext]
I still get to choose "Confirm wipe? No No No.... Yes - Wipe Dalvik Cache" but I'm starting to think this has something to do with some ROMs not working (properly). Anyone knows how to get around this? Thanks!

I think there is a function for it in Titanium Backup. Sorry if it's not exactly what you're looking for.

Thanks I'll try that, do I need titanium backup pro for that?
I've got a relatively stable ROM now so I'll try it later when I have more time.

do it again and it wont say the E:unknown path thing... at least mine doesn't...

Or you could always do it manually. ES File Explorer is a good app. Dalvik cache is safe to remove because the only thing that can happen to you is that it will be created again. Also, the pro version of Titanium backup (that, in my humble opinion, is absolutely worth the money) has functions like integrate dalvik to rom and undo the integration, which do come in handy if you're changing roms and tweaking them up.

you clean it directly by link2sd...there is the specific option

[Q] *wipe*

Hi all!!
I know it is a very very, VERY dumb question because seems that everyone knows the answer and mostly because i am in my 3rd ROM and most of then suggested/requsted a fullwipe. So I searched the forums and wiki but i don't have a clue about what is a full wipe or super wipe or *wipe*
Sorry for that quanstion and thanks if you could answer.

Full wipe: Format data, cache, dalvik cache. It does not touch your SDcard data.
Edit: Usually people also Wipe Battery Stats. I found it unnecessary so I forgot to include. It may also involve formatting your SDcard if you have funky stuffs in there. (apps2SD for example)
If you use ClockwordMod, for example, you would have to choose Format data/factory, then Advanced => Wipe Dalvik Cache and Wipe Battery Stats
Super wipe:
Fallen Spartan said:
Basically it does the following:
1) Call erase_image on CACHE, SYSTEM, USERDATA, and BOOT partitions
2) Mount /sd-ext (if it exists) and delete all files from it
3) Delete all files in the /sdcard/.android_secure directory which is where all the froyo apps2sd files live
4) Run e2fsck (file system repair) on the your ext partition
5) Log all output to the /tmp/wipe.log file (if you care)
You will need to power off and reboot back into recovery after running this to install a new rom....as you won't have one on device
If you forget and try to boot normally you will get stuck at splash screen, then you will have to pull battery to power off.

To super wipe you often need a zip file and flash it in recovery. Example:

an added note
fastboot wipe is still the cleanest wipe
<fastboot -w>
i tend to over kill so do fastboot wipe first
then boot into recovery and do a factory reset and wipe cache, dalvik cache again
then do a superwipe.
sounds like over kill? well it keeps me from having issues when changing roms - i change often so these 3minutes spent save me lots of time later
