[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 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

Need help flashing ROM

So, I've rooted and S-off'd now i want to flash a ROM - this one: http://forum.xda-developers.com/showthread.php?t=1143456
But one of the first things i have to do, is wipe data/factory reset. But i have the recovery-RA-desire-v2.0.0-CM.img recovery image, so when i want to wipe, i get the following options:
- Wipe ALL userdata
- Wipe only /data
- Wipe only /sd-ext
- Wipe only /sdcard/ .android_secure
- Wipe only /cache
- Wipe only Dalvik-cache
- Wipe only battery stats
- Wipe only rotate settings
So when the tutorial tells me to wipe data/factory reset, does it mean "Wipe ALL userdata" or "Wipe only /data"?
I would ask the question in the ROM's thread, but i do not have enough posts to post in the android development area

Wiping everything is the recommended procedure for most roms. Wiping only data, for example, leaves data on the sd-ext partition which might result in problems. Basically wipe all in an option which spares you the time to do manually all the wipes necessary to install a ROM.

If I were you I'd use fastboot to erase boot, system, userdata and cache.. yes the, boot & system files are technically overwritten when you install a new ROM, and everything else is "deleted" (if you choose to delete it from recovery), however it's a more "cleaner" install that way (as in use fastboot to erase boot & system), and most of the time ROMs appear to work better.
You can use several tools with fastboot.. you can use cmd, however commands are specific and it takes a while to learn them (there are a lot of guides, but it takes practise), and there are some software platforms. Personally, I prefer to use fastboot commander as it gives me the most features, it however requires java JDK and android SDK (possible you already have this so check before installing.. if you are going to install it in the first place)

Gotta love the helpful people in this community

The steps to a clean flash are:
-wipe cache
-wipe dalvik
-make backup (just in case)
-wipe data/factory reset
-format system (under mounts/storage)
-flash ROM
-flash gapps
-reboot
-ENJOY
Hope that helps.

Lock the bootloader and then root again. This will wipe EVERYTHING!! I repeat, EVERYTHING will be erased. ALL OF YOUR DATA will be gone!
That is the only way to ensure you won't have traces of anything left over.

What you wrote is misleading.
"Rooting" does not wipe anything.
Unlocking the bootloader will wipe data, but that's it. It will not erase /system, /boot, or /cache.

Just curious. Have you un-checked Settings -> Backup & reset -> Automatic restore?

Lol.. if you want a functional wipe then do my steps. It was needed with the incredible.
CWM - 6.
1.) Wipe data/Factory reset
2.) Mounts & Storage > Format SYSTEM - make sure it's SYSTEM and not Sdcard.
This helps clean the residue left from other roms
3.) Use superwipe if needed or just want to use it
4.) Flash Rom, gapps
5.) Wipe cache/dalvik if given instructions to.
Those are the proper wiping methods.
If your doing a flash over -
1.) Wipe cache and dalvik
2.) Install Rom and if necessary gapps
3.) Fix permissions?
Reboot

Even that doesn't do a complete wipe, as it doesn't wipe the kernel, nor does it wipe the data in /sdcard (in which some apps store their settings).
If you want to fully wipe, transfer the files/data you want to keep to your PC, reboot into fastboot mode and type:
fastboot erase system
fastboot erase boot
fastboot erase userdata
fastboot erase cache

Don't think boot is an option in CWM "dunno why" lol, I suppose if you wanted to go through those steps
CWM should add a few more options such as those.
