when to wipe data and cache?

Hey guys,
Question from a noob here. When exactly should you wipe data and cache?
I noticed that when I recently installed the gala x theme from rom manager before the install I was given 2 options. Make a back up and wipe data and cache. I went ahead and of course made a back up but chose not to wipe data and cache.
What is the right thing to do?
Thanks in advance

no one???? Some one must know.

If you are on a clean rom with no themes and your installing a new theme then no. The only time you need to wipe date and cache is if you are going from one rom to another. The reason for that is because of conflicting info.
So yes you are good if just adding a new theme

Just a side note here; I wipe my cache weekly. I noticed my phone getting slow after the 2.2 OTA. Also, I got all kinds of FC's and other problems. I wiped my cache ONLY and it fixed all of my problems. Your system will rebuild the cache again as needed, so the first load may take a little longer, but there is less junk to sort through, so it's quicker to load on the next request. Oh, and as long as you do NOT wipe the data you won't lose anything.

Would it be advisable to wipe data and cache before restoring a back up?

What kind data is deleted with "Wipe data" ?
I come from fixed sbf, because of black screen and white led.
After that I had internal memory 128mb.
Tried Factory reset and Wipe data, nothing.
I tried to do according to the Beginners guide.
But after installing CM7, and kernel Froyo and Gapps, there is not said, that wipe data is needed (in cm7 instructions).
So I got stuck on the Google logo screen.
Once again, from the beginning with fixed sbf.
Does it make difference, because I have 128mb internal memory or is Cache somewhere else? In ram ?

[Q] Possible for ROM to be applied "half way"?

I'm new to flashing ROMs on the EEE Pad, but not new to flashing ROMs in general...have a Samsung Galaxy Skyrocket that I have flashed probably 50 times alrerady. That being said...I'm confused. I rooted my tab and flashed a ROM. It looks like the flash worked because checking the version in "about" shows the new rom. The strange thing is that all the apps I had installed prior to flashing are still installed. I followed the normal steps...factory wipe, format cache, data, system. Does this make sense to anyone? It feels as if some of the rom flashed and some didn't. Any help would be appreciated.
PS...I would have posted this unter the ROM's thread but since I am new to the forum I can't until I have 10 posts.
Examples of this are pandora (including my login info)...email accounts, facebook accounts, etc

are you positive you wiped your data? if you did, everything should be gone.

Well...I ran a super wipe script that was part of the rom download now that you mention it. I'll give it another go but wipe by hand and see what happens.

aha! I bet that is it, I have heard people saying not to use the super wipe scripts. I don't know much about it but I'm nearly positive that's the problem.

it may also depend on if you are using the full wipe which does internal memory or the light which i believe leaves your apps untouched

You cant use superwipe if you got a recovery that only reads from internal memory (/mnt/sdcard/), as superwipe will also wipe your rom file, leaving you with nothing to flash.

oh so that's the only reason? not because it doesn't work right or something?
Btw does the Rogue CWM let you backup/restore from a USB External Drive? or just /Remoable/MicroSD/ ?

As far as I know, yes thats the only reason.
The version Im using only allows internal (/mnt/sdcard/) and external (/removable/microsd), there might be some version that allows USB as well, but I doubt it tbh.

Thanks for the responses...I figured I would skip the superwipe and just do it all by hand. All good, but ran into a new problem. Apparently I don't have the option for mounting an external SD card. It's installed and when booted into the OS I can see it and everything, but the mount option is missing from clockwork recovery. This is both with the touch version (5.8.1.8) and the non-touch version (5.5.0.4). Luckily the manual wiping didn't clear out the internal SD card so I was able to just restore my nandroid backup.
A - anyone have issues with the "mount sd-card" missing in CWR?
B - Apparently the tablet version of ICS installs apps to the internal SD card so doing a wipe doesn't really clear out all the apps. Does that sound right?

Both those CWM versions does not support external SD card afaik. Only internal.

That would be why then I guess. Doh! I'll check around but I didn't see newer versions that worked with the tf 101. Thanks for the reply!

I use cwm 5.0.2.7 [via RecoveryInstaller.apk], and I have had no problems, I can mount my MicroSD

Market not showing up

Alright so I did the whole CM7 R11 trick to have twrp. Now after all that I went back to flash gapps, Google works but the market isn't there. I've done everything but go back to one click and redo everything. Also when I was on cm7 (I'm on mokee now testing to see if it wasn't cm7 only) after clearing cache and dalvik, fixing permissions, a lot of things started to force close. Any advice/help will be appreciated

I would suggest you reformat your SD Card from blue CWM with 2048 partition and 0 swap and reflash. Make sure to backup your SD Card before doing this. I had the same problem and that fixed it for me.

When I went from bml to cm711twrp I skipped the beginning part where it said to sign in or create and it wasn't there. So I did a factory reset/system wipe and installed cm711 and flashed gapps again. I signed in and it was the "market". I then got a fc b/c it updated to the play store.

[Problem] Freezes when trying to wipe data/factory reset on CWM recovery

Hi, I want to install a new ROM, and is the first time I'm trying.
I've followed the steps correctly, and when I press the 3 button and it opens the Samsung recovery, I hit reinstall packages and it loads the orange cwm recovery.
Now this is where the problem begins.
I need to wipe data/factory reset, but when I hit it the phone freezes. (If I wipe on the phone it works, and on the samsung recovery it also works.)
If, on cwm recovery I wipe cache it works, partitioning on cwm recovery also works.
First this is what happened:
-- Wiping data...
Formatting /data...
Formatting /cache...
Formatting /sd-ext...
E:format_volume: make:extf4fs failed on /dev/block/mmcblk0p2
Formatting /sdcard/.android_secure...
I partitioned on Rom manager and this happened:
-- Wiping data...
Formatting /data...
Formatting /cache...
E:format_volume failed to unmount "/cache"
Formatting /sd-ext...
Formatting /sdcard/.android_secure...
I partitioned again on cwm recovery and this happened:
- Wiping data...
Formatting /data...
Formatting /cache...
Formatting /sd-ext...
Formatting /sdcard/.android_secure...
It always freezes on "Formatting /sdcard/.android_secure..."
In all three cases.
I don't understand why, and my question is that after it freezes if I turn off the phone (by pressing the turn off button which works), and hit reinstall packages again, and clean cache and delvik cache and load the ROM, if it will work.
I don't know what more can I do..

Why are you partitioning your SD card so many times?

Because it wasn't working correctly?
btw, if I format the sd card, the partition will still remain, right?

Since CWM isn't partitioning correctly, try partitioning on your computer. This guide is helpful -> link. The ext partition should be 1024 MB (=1 GB) or 2048 MB (=2 GB) depending on how much space you want for apps. Swap should be 0 MB. The rest should be FAT32 for your storage. I personally only have two partitions, my FAT32 one and my EXT one, I don't have a SWAP partition.
Format should just erase the SD card, not the partitions, though I might be wrong.

I partition on the computer which didn't worked then I partitioned on the app rom manager but the maximum ext was 512 mb..so I went to partition on cwm recovery when booting..and put 2048 for ext and 0 for swap as you told me..
But if I delete the data on samsung recovery, and then boot CWM recovery, and wipe cache and the dalvik cache there, it's might work right?
thanks a lot.

When you say partition on computer didn't work, what do you mean? It didn't partition your SD card? Or it didn't solve the problems of the wipe freeze? I think you need to stop trying to partition it using so many different tools, erase all the partitions and start over on a computer. It should work, and if it doesn't then it might be a SD card issue.
Edit: Hmm, yeah that should work technically! I've asked on the ROM thread, lets see what they say.

When I partitioned on the computer the ext partition wasn't working right..the software didn't even recognise it..but I think that now it is rightly done..
Maybe tomorrow I'll try to wipe data on the samsung recovery, then I'll reinstall packages and on cwm I'll wipe cache and dalvik and then try to install the rom..maybe it will work..I hope so!

Ext is a Linux file system and Windows won't recognise it. I'd recommend a fresh partition (delete all partitions and then add in your FAT32 partition and EXT2/3/4 partition, making sure both are Primary partitions).

I actually partitioned both of mine as Fat32 and it works great

I think that now it is formated correctly. But the problem still remains.
I think I'll try to wipe the data on samsung recovery, and then complete on cwm recovery.
EDIT: so, I was wiping data and like always it friezed, so, I turned it off, and he turned on on samsung recovery, I pressed reinstall packages, and on cwm deleted cache and dalvik. Installed the rom, and it worked. The rom is functioning, and the problem I had with the "message not processed due to insufficient funds" disappeared. I think the rom is working right, but it doesn't vibrate when I receive sms, and the leds doesn't work either. Don't know if it's like that, I'll see on the rom thread.
Thanks a lot.

Glad you finally got it working I would highly recommend doing a reinstall using the new voodoo red CWM recovery after wiping all the data, etc ... just to make sure all of its completely wiped (reinstalling different ROMs sometimes leaves old data on different partitions and takes up space). You should also re-partition SD card just to be safe. But of course this is all optional, just my two cents
You need to play around with different settings. Like under Sound you'll have the Vibrate option set to Only on Silent, Always On, etc. On the SMS setting itself, you can set different ringtones, etc under setting. LED only works on Missed Calls and Charging atm. The only thing that doesn't work (for me anyway) is on some forms, like SMS To field, when you type a name it doesn't come up till you select it. This is a theme issue faced by everyone and there are no fixes atm. Did you install LEAN GOV or the full one? If you installed LEAN, mine didn't come with Google Search installed, download the apk from the internet and install. Using the Link2SD app (which I recommend for saving space) you can Press+Hold the Google Search app from your applications list and convert it into a Systems App. This lets you use the search button on keyboard and search widget as well! I also recommend ADW Launcher which you can install from the Play Store.
If you have any problems, don't hesitate to hit me up Click Thanks if something I said was helpful

Another app I would highly recommend installing ASAP is Titanium Backup. It'll save current versions of apps and data for you to as a backup to your sd card. It's really come in handy a number of times as I've tried new roms or switched back to an older version if an app comes out with a bad update.

Yes, I went on Sound and I put it on Vibrate Always. It doesn't work. The only way for me to know it I received an sms is on the top on the notifications. No even the messaging icon says that I have a sms. But that's ok. When I type a name to send a message the name doesn't came up either. That's a bit bad, by I can handle it! I installed the LEAN GOV-PERFORMANCE.
I'll see the rest that you talked about!
I installed adw launcher, but I don't know were it went. On the settings the "theme settings" doesn't work, and it says to force close.

[Q] SCH-R530U Complete make-over NEED GENIUS**!!!!

I have a SCH-R530U US Cellular GS3 running on JB 4.2.2 with AOKP's mr1 build 5.
Kernel: 3.0.67-aokp-00038-g5a02406
I'm bored of this ROM and want to try Liquid Smooth for the features and hopeful battery life extension. I have been trying to get my phone back to stock EVERYTHING every couple weeks for the last few months now, and have not found any stock rom/kernel files that do anything other then brick my device into a hard boot loop. I have a NANDROID backup, so all is not lost, but I'm just so sick of not being able to find ONE file that will give me stock kernel and stock ROM so I can try a new ROM with new features and speed. I would flash LS over the AOKP build, I just haven't found any info on whether or not the ROM is compatible with my kernel, or if that's even an factor and Iv freaked out too many times over thinking my phone was F$*!ed to be that ballsy in trying something without having exact instructions or some sort of literature/video. So Id rather be safe then sorry and start completely fresh.
Also to get rid of all the non-sense i have on my phone from flashing tons of files to get rid of AOKP, and not knowing how to delete them.
The other issue. My SD card isn't recognized by anything. I cant move apps to my SD card with any app out there, the file is emulated and what i think happened was somehow, I ended up with two SD card files, and they have mixed files in them. So being as newb as I am, idk what files i need to keep in order for proper functioning of my phone and which I can delete, so i can move apps to the SD card and pictures and all that stuff to free up space on my phone. Im more then willing to delete everything on the card, but that wont fix my unorganized internal file clusterf$!*#.
Iv seriously being looking for months, downloaded ADB toolkit to try and get stock back that way, but just another boot loop.
TL;DR
1. Need stock ROM/kernel files for my version that will actually work and not bootloop me.
2. Can any ROM be flashed over any kernel, or are there restrictions with specific ones?
3. How can I fix my SD card problem (not recognizable by any App2SD app; literally none -says my SD card is emulated), with messed up internal files?
PLEASE HELP!!!!

Through your recovery do a full wipe (system, data, cache, dalvik) Sounds like you want to wipe your internsl sd too? Depending on where you keep your info you can wipe your internal SD but it's not necessary.
When you flash a ROM it will come with it's own kernel so you don't have to worry if a ROM is compatible with your kernel. Just make sure you flash a ROM that is compatible with US Cellular.

Thank you for your reply, honestly.
I vaguely remember doing a full wipe (system, cache, delvik, and data) and it not fixing the issue. But, I will try again. I'm more concerned about my SD card issue and all the messed up files. Will wiping all this fix that? Using ES explorer, I have about six /0 files... Idk if you know much about that, but from what I've learned, within that ONE /0 file, there should be storage for my SD card (data/media) and of course, there's nothing there. So, do you think or do you know that doing a full system wipe will remedy the problems? No tone intended, not trying to be a jerk, simple curious for the future.

Just format the SD card. Wipe everything off if your comfortable with losing the info. You can save important stuff top your CPU if necessary.
