[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.

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] *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

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.

[Q] ViperX venom tweaks won´t stick - flash problems

When installing the new uppdate ViperX 3.3.0 - can I do a full wipe and install that or do I need the former versions first (3.2-3.2.4)?
I´ve had problems flashing numerous times but finally got it on the phone and then made the 2 other uppdates ota to 3.3.2 but when I´m in the venom tweaks and change the max cpu to 1300 and changes back to 1500 after a while and sometimes after reboots.
I checked the ticker "aply settings on boot". Sometimes the min cpu freq also changes by itselfes to 1300....
The "mount system r/w" ticker also never stays checked....
I´ve had problems flashing, it only worked when I didn´t do a full whipe on the 3.3.0 version.
Sometimes the flash crashed after 10-15% and sometimes when the flash was ok and finished I ended up on the white htc logo.
I did this:
1: Move the zip file to htc in my download folder.
2. using winrar, get the boot.img file - moved that to my Boot_Flash_Script folder.
3. Go to Bootloader
4. Connect htc one x to the pc - fastboot usb
5. In the Boot_Flash_Script folder - dubbelclick on the flash-boot-windows file.
The boot.img flashes ok and also the cache is cleared.
6. unplugg the htc and go into recovery.
7. Using Aroma Installer I wipe cache, wipe dalwik cache and (maybe this is wrong) wipe System.
8. Then I click Install - find the zip file and excecute that.
9. Choose the stock kernel.
10. Full wipe.
11. flashes.
Then it sometimes crashed at 10-15% or flashes ok and when i hit "Reboot" it hangs itself on the white htc logo.....
This also happened when I tried to flash Icecoldjelly…
What am I doing wrong?
Noooob-thanks,

Nothing really, but download the latest full rom and check the MD5 number, flash the boot.img again and do a full wipe in recovery....
Wipe cache partition
Wipe data/factory reset
Advanced - wipe dalvik cache
Mounts & storage - format cache, data, system
Just to be sure and then install the Rom.zip. choose in the aroma for a full wipe again and continue....the question about the kernel you answered correct with NO.
the mhz option probably doesn't stick because there is only a stock kernel available, we don't have custom kernels yet ....

When wipeing and factory reset, does it erase anything on my sd-card?
It shouldn, right, since its on sdcard0...?
Even with a factory reset it shouldn't erase nothing?

Nope

Great.
Thanks!

So after flashing the boot.img, go into recovery and basicly wipe everything except external storage?!
Under "Mount" there are 4 tickers : Mount System, Mount Data, Unmount Cache, Unmount SD Card.
Unmount Cache & Unmount SD Card are checked....
What to do there?
And then just flash the Rom, Full wipe in Aroma, chose stock kernel and that should do it?!

I will quote myself ! Do NOT touch the mount stuff only touch the FORMAT stuff
And ofcourse you do NOT format sdcard !!!

Flashed the boot.img.
Wiped everything and did a factory reset then flashed the Rom and it worked.
Think the factory reset did the trick - the only thing I didn´t do before.
Thanks!!!!!!!!

Finally !!!
