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.

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.

Hello, I'm just trying to gather as much information as I can and be clear about everything before I install a custom ROM. I have already rooted the nexus s.
The ROM I'm interested in is this CyanogenMod 7.
In their installation instructions it says
- Format the system, data & cache partitions of your device.
- Perform a factory reset.
From another guide (AddictiveTips) they just tell us to do the following
- Select wipe factory/data reset.
- Now, wipe cache and dalvick cache.
The xda thread tells us to format system, data, and cache partitions. But the AddictiveTips guide only seem to tell us to format the data & cache partitions.
So my question is, does the system partition automatically get formatted while installing the new ROM, or do you have to manually format it by going to mounts and storage > format system before installing the ROM?
Also, do you guys recommend to format all the required partitions by going to mounts and storage or by selecting wipe factory/data reset and wipe cache from the main menu? Thanks in advance.
...anyone?
Wipe factory/data reset (this will obviously also wipe the caches)
Install zip from SDCard (ROM)
Reboot.

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
Hi,
Today I successfully rooted my galaxy Tab 2 7 P3100. What I am not sure is when and why we need the
Wipe Data/Factory Reset
Wipe Cache Partition
Wipe Dalvik Cache
I want to understand because I plan to try couple of other ROMs. Should I follow the above procedure every time I flash a ROM or is there a better way where avoiding any of the above is an option.
Regards.
to minimize the conflict that would occur if you use a different rom base
try it without wiping, usually meet force close dialog after booting
all i know is that wiping cache will clear data related to applications, so if you have an app force closing all the time it is sometimes handy to wipe that app's cache from the settings or wiping the entire cache from recovery.
wiping data/factory reset however will remove any app you have installed and all your personal files that you've put on the device.
Basic breakdown,
If going from one base ROM to another base ROM like stock to CM, CM to AOKP, stock to AOKP or anything like that you will need to do ALL 3 wipes.
If going from like a CM10 nightly to a newer nightly you can usually just wipe CACHE and Dalvick
If you flash addons you will usually need to wipe cache and Dalvick
BASICALLY just do what the INSTRUCTIONS for the ROM your flashing SAYS to do.
Wiping Dalvik cache before and after flasing of ROM

First of all a BIG THANK YOU.
Now One more doubt there is this ROM which I want to flash and it says to wipe dalvik cache before and after flasing the ROM. Please confirm only Factory reset will clear the existing ROM and wiping Cache and Dalvik cache wont affect the existing ROM(or internal SD Data)
Thanks again.

OK well flashing any ROM will replace your current ROM, NONE of your files (music, pictures or things like that) are touched by ANY of these wipes, Factory reset wipes out installed apps, wiping cache and dalvik after flashing or hell wipe data/factory reset won't touch the apps "built-in" to the ROM.
remember the ROM is your operating system and your files (music, pictures, and other stuff) are in the internal SD which is a separate partition from the ROOT system folder where the OS files are.
Wipe Data/Factory Reset - wipes all APPS and Google account information and resets all devices settings to default
as for the other 2 read through the answer here http://android.stackexchange.com/questions/25859/why-do-i-need-to-wipe-dalvik-cache it explains what the other wipes are about.
Hope that covers it, basically jumping from one ROM to another the most you can lose is your basic settings and your APPS (which can be redownloaded, if you didn't use an app to back them up first, but you would lose any progress in your games if you don't back them up).
I am a little confused on the terminology. I have done some searching and I came across the same question: http://forum.xda-developers.com/showthread.php?t=2107425 but it didn't really explain what manual format/system means for TWRP...
For instance, to install Slim Bean 4.2 build 8, it suggests to do a full wipe and then manual format system before flashing the rom.
How would I do this in TWRP? I want to make sure that this is DIFFERENT from format /data right? It is also different from "just" wiping "system" through "Advanced wipe" in TWRP?
Thanks in advance guys!

If you want to flash a new rom you have to go into TWRP
Wipe: Cache + Dalvik Cache + System
Wipe System is the same like formatting system

Thanks! Appreciate it. I was just wondering if formatting system is more of an active process that's different from wipe (eg. writing in zeros).

no its same
wipe = format
You don't need to wipe anything for flashing a newer version of some ROMs such as nighties. A factory is usually recommended to wipe the cache, dalvik cache and userdata to return the ROM to stock. Then when you flash a new ROM it will overwrite your current one.
Format System during SLIM installation
Hi,
Formatting the System is not risk the whole data i have on my device? in the past (as far as i remember,) doing it, deleted all the information i had on the device completely so it was even impossible to recognize it on the PC even all the drivers were well installed.
Looking forward for your advice.
