i got virtuous unity 2.37 and want to install 2.39. its suggested i do a ext4 wipe before nstalling 2.39. i want to make sure i'm doing this right.
so, to do a full ext4 wipe, i must boot into recovery and then wipe all data, cache, then go to advance and wipe dalvik? is this correct?
Maybe you must go in Wipe / Format menu,then format sd-ext.
Go to mount and storage, click format sd-ext and click yes. Your ext4 partition is now wiped.

hi itachi.. does your advice regard wiping the sd card?
also, someone suggested that an ext4 wipe involves going to Wipe/Format and selecting wipe data/factory reset, wipe dalvik cache, format system, format data, format cache and format boot. is this true?

It does not affect the FAT partition of the SD card. Only the Ext partition. And by wiping data, dalvik, formating system, data, cache and boot, you are literally doing a full wipe of the phone which people normally do when they change from 1 Rom to another.

thats exactly why im doing a full wipe.. to upgrade my rom to a higher version. but your way of wiping data seems like it involves wiping data from the sd card, which is risky and unnecessary when installing/upgrading a rom. and it can wipe out the rom on the sd card that you want to install anyway. so then whats the point'?

I don't mean changing to a higher version, I mean changing Rom (like from cyanogen to miui) . If you are upgrading to a higher version you do not need to wipe data. All you need to do is just wipe cache and dalvik, boot and system too if you want. This way you will get updated to the latest version while still retaining your application data.
And yes, technically you do wipe the sdcard, but only the EXT partition, which is where your apps are placed in if you use A2SD+. Your FAT partition, which is the one recognised by the computer and where you put all your data in, is not affected. Hence it will not wipe out the Rom you are trying to install on the sdcard.

quick question, im new to rooting the transforner and i just want to know, when i wipe to install prime will it erase my music that is on the internal storage? If so, is there a different way to wipe to keep certain files? Cause i also have my titanium backup files on internal as well, thanks in advance.
First of all, your title made me laugh for a good 1 minute. Somehow, "question about wiping" just doesn't sound very technical and sound more like it has something to do with our bodily functions.
No, "wiping" cache and data will not touch your files. Android is different than windows. Windows OS has 1 big partition where everything is in there. Android has 12 partitions, each one has it's own purpose. When you wipe the data partition, what you're really wiping is app data partition. There is also a user data partition where all your files are kept. Unless you do a format of your sdcard in the advance menu, all your user files are safe.
So, before you install a custom rom, make sure you wipe cache and data/factory reset. Also wipe dalvik cache. Trust me, all your porn files will still be there waiting for you.
Sorry, I have a weird sense of humor.
Lol, thanks buddy. Ive never had an android device with an internal sdcard so i was a little concerned. Thanks again.

I was wondering, is a data/factory wipe always necessary? When I flashed Revolver 3.9.3 for the 1ste time from stock rom, I did a data/factory wipe, cache wipe and dalvik cache wipe in CWM. When updating this Revolver rom to 3.9.5 using zip-file, I only wipe cache and dalvik cache. On my Moto I wipe cache and dalvik cache before and after the zip update when updating a custom rom, but I'm not sure if the latter is necessary. I guess a data/factory wipe is only necessary when flashing a new base rom?
wiping is usually recommended as sometimes if you install with out wiping it will cause weird problems :/
Can someone clarify exactly what I means to "wipe" a device?
I have installed CleanRom. In recovery I reset the device, wiped cache, and wiped Dalvik cache. I did not wipe the SD card. is this correct? If so, is there ever a need to wipe the SD card?
Thanks!
I'm not an expert but I'm pretty sure there is never any reason to wipe the SD card when flashing roms. I've flashed every version of cleanrom released so far doing exactly what you did and haven't run into any issues.

Yeah there's really no reason for you to wipe your sdcard unless you're planning on returning your device. The rest is correct.
When "wiping" a device for installing a new custom ROM, you typically should wipe cache, Dalvik, and data.
Data can sometimes be kept, if the base ROM is similar. But doing so may cause random bugs, and you may end up having to wipe data and reflash. Wiping data is usually the safest.
Wiping SD card is not necessary.
I must have something wrong then because I do the same wipes you mentioned, cache, dalvik, and data and every time I do it my SDCard contents, are also gone. Has no one else had this problem?
Thanks
I've been using custom roms for some time now; generally when I install new roms, I do the following:
1. Nandroid backup
2. wipe data/factory reset
3. wipe cache
4. wipe dalvik (although i get an error that the SD ext partition not found)
5. flash rom
The installation instructions for Slim Bean suggests that I do "Full wipe, and manual format /system".
My question is twofold: (1) what is "manual format /system" and (2) is there anything in addition to the above that I should do to fully clean out the phone? I have not formatted the SD card, but I guess I can and just leave the data from there on my PC.
Any help is appreciated - thank you!

Be sure you back up all data from SDcard to PC, and then format sdcard.

1) In CWM, Mount and Storage-> format System, format Cache, format data..:highfive:
2) If you want to fully clean out your phone than do all formats including wipes, format sdcard, do not mess with other things.

Thank you - if I do that first step ("In CWM, Mount and Storage-> format System, format Cache, format data"), do I need to back up my SD card first?

No, in that case you don't need to backup your SD card.:highfive:

Just make sure u back up the SD card on computer so u have it. Plus be careful because there have been issue with phone not communicating with PC after SD card formating since ur also deleting those files too. So only do if really necessary.
But
I would NOT format the SD card unless ur having issues.
Just do factory reset, wipe cache and dalvik more than once. There is also a zip file called "format all" that will do all three at once with a simple click. You can find it on XDA
Good luck

Hi..
I am always confused about this. When flashing a custom ROM, will wiping the system not delete the ROM zip file?
Also is wiping cache, system and data the only things I need to do.
Like there are so many confusing posts in and out of xda. The official CM page says nothing about wiping cache and system while the CM FAQ page here says to wipe all three I.e. cache , data and system.
Some say to do factory reset and some say not to.
What do I do man?
Cache, Data, System and Internal Storage are all separate partitions. Wiping one does not affect the others. Factory reset usually does the first three, you have to manually specify anything else.
Your ROM zip will be on the 'Internal Storage' partition which is why it survives a system wipe.

Thanks for your quick response man. Also one more thing.
Is it necessary to wipe all the three when flashing a ROM and does the order in which they are wiped matter?
It's a very good idea. Not wiping can cause all kinds of problems. Order does not matter.

Another thing again..
Should i wipe data/factory rest or just wipe data..
And in case of cache should i wipe cache partition or just cache or dalvik cache also..
Thanks in advance!

Wipe them all if you want, but factory reset is usually enough.
follow the instructions in the ROM thread where you looked, some steps omitted or changed to be installed, I hope you have no problems, I recommend that you make a backup of your current ROM.
Am currently on Crombi KK, looking to try out the Lollipop 5.0.2 Zombi-Pop Beta. I know just enough to be dangerous. Installed Crombi-KK to internal, then reinstalled to run ROM2sd a while back, SDcard set up in GParted. Have TWRP 2.8.4.0, just want some clarification on how and what to wipe. ROM thread states to do a full wipe, but I've never been totally sure on what constitutes a full wipe from recovery. From Wipe option in TWRP, there is Advanced Wipe and Format Data. Do I chose one or another or both? In Advanced Wipe, there are 6 partitions:
Dalvik Cache
System
Cache
Data
Internal Storage
Micro SDcard
What one(s) do I select? Since I'm running ROM2sd, do I need to run ROM2sd zip first?
TIA

A full wipe is a wipe of data, cache and Dalvik. In most cases that is sufficient moving to a different rom base and the default in TWRP under the Wipe menu.
If you encounter weird problems, format /data/ (and don't interrupt it. Takes 90 minutes or so!)
There are only very specific scenarios where wiping /system would make sense. /system gets formatted anyway during rom installation - no need to wipe it.
Internal storage - if you want to get rid of everything but do not want to format /data/. Wiping data wipes everything except /data/media/ in TWRP (that's where your personal files live). Wiping Internal Storage wipes everything including /data/media/
Micro SD - wipes your microSD or - in the case of data2sd/rom2sd - the fat32 partition thereof.
If you want to wipe/format your rom2sd /data or /system partitions, yes - you have to flash rom2sd1.zip first
