[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] noob question again - about flashing and back up of info

ok if and when i do flash my Dinc to a new rom i have read that it is good and i guess necessary to do a factory wipe and some other wipes that i dont understand yet.. (that i guess i will find out later)
How do i get my info (contacts, and other stuff) back on to the phone..
i dont have to re-enter each contact by hand again do i?
thank you again..

The single easiest way to handle contacts is through your Google account. Assuming you're signed onto the phone (Gmail), your contacts should sync online automatically. Sometimes this doesn't work as well as it should. You can go online and look at your Gmail address book. All that stuff should sync up with what's on your device. If not, edit it there, then sync it up with your device.
When you flash a new ROM, sign on with your Gmail account and your entire address book will re-sync with your device. It's just that simple. And it kicks ass!

sweet thanks
sweet thanks!!! i was thinkin it was something like that .. my phone before this was a Blackberry Storm.. and backing up info was easy on that..
one more question..
Select wipe factory/data reset.
Now, wipe cache and dalvick cache. ?
is this pretty much self explanatory when i get into this..
i am just trying to think of all questions before i do this .. was thinkin of doing this tonight.. and i really dont want to mess up my phone..
thank you again!

God... I HATED the S2....
No need to really wipe the cache. That's usually included in the factory reset/data wipe. Dalvik cache is good to wipe though. And if you wanna be EXTRA thorough, go down to "mounts and storage" and format /system.
Also, feel free to ignore any recommendations that you wipe 3 times. It doesn't do anything except put wear and tear on a type of memory that's already got a limited life span. The more you do it, the slower NAND tends to get.

these are some instructions i got for one sens rom..
Instructions:
Begin by copying the ROM and you downloaded from the link above, to the root of your SD card.
Once the file is copied, reboot your device into recovery mode.
Once in the recovery, make a Nandroid backup.
Select wipe factory/data reset.
Now, wipe cache and dalvick cache.
Select install zip from sdcard > choose zip from sdcard.
Select the ROM you copied to your SD card and let it install.
That is it, once the ROM is installed, reboot the phone. For updates and queries, vi
and this is another one..
1. Put Rom on the root of your SD Card
2. Compare MD5 Sum
3. Reboot to Recovery
4. Wiping these:
Main Screen:
wipe data/factory reset
wipe cache partition
Advanced:
Wipe Dalvik Cache
Wipe Battery Stats
Mounts and Storage:
Format-
/boot
/system
/datadata
/data
/cache
5. Install Rom from SD Card
6. Reboot and enjoy!
Note: First boot is really long!
since i have not done this yet .. i dont know what some of this stuff is..

[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

[Q] Phone Constantly Rebooting!

I was wondering if anyone can help me. I have looked at the other posts which relate to a very similar problem, but none of them have quite the same problem as me. Basically, all the phone will do is show the 'HTC Quietly Brilliant' loading screen and it is stuck in a reboot cycle. I can access the bootloader and I have tried to factory reset with no luck.
I was watching a YouTube tutorial on how to flash CM10 onto my One X (I do have ClockworkMod and all of that stuff installed already). Everything was going well, but the video only briefly (for maybe a second) mentioned the fact that you have to put the CM10 zip folder onto the phone storage before you flash the boot.img. I went on and followed the steps and tried to flash the boot.img, but as I said earlier, all the phone will do is reboot over and over again. I have charged it to full battery so this should not be a problem when I go to fix it.
I would be really grateful for any help on the subject as I contacted the person who made the tutorial, and he has not responded. Thanks in advance.

Have you placed the ROM's zip file in your phone's root?
If you haven't, go to fastboot and flash CWM 5.8.4.0 and then go into recovery > mounts and storage > mount USB. Now place your ROM into the storage and flash it via install zip from SD card. Don't forget to wipe data partition, cache partition and Dalvik cache.
If this wasn't your case, just try erasing data partition, cache and Dalvik cache again.
If it still doesn't work, try flashing another ROM.

Thank You!!!

Thank you so much. I had CWM 5.8.4.0 already, all I had to do was mount USB and put the CM10 zip on the phone storage! I also wiped the caches, the phone works better now than it ever has . Thank you so much again, really appreciate the help

[Q] recovery, something is corrupted at bootup

My phone just boots to the "Saumsung Galaxy Note II" screen and is stuck there.
If I do volume up and home, it goes into the recovery screen but I m afraid using odin would erase everything.
I want to save my data, what should I do?
i cant do anything within recovery.
now i have a bunch of of failures..
i can reboot, apply update from adb, or external storage, wipe data, wipe cache.
i did what you told me, to wipe cache, the bootloop persists.
which rom do i use? i dont remember what i used.
i dont remember what i did to make this happen. im not sure why you say loop bc it doesnt disappear.
it says failed to mount many things..
Please specify what I need to download in order to save my data, thanks!
