Before installing a new ROM, I've always used Recovery's wipe functions (data, cache and dalvic cache). Today I discovered that at least one ROM (Sense-O-Maniac) seems to require that SuperWipe be used. On the other hand, I see that another ROM (OpenSensation) requires the use of Recovery's wipe functions.
Why is this?
Thanks.
To keep it simple:
"Partition Tables"
That's why.

Not true...
Where do you read S-o-M requires Superwipe.
On the other hand i only build in a option in the installer to conduct a Full Wipe.
This full wipe (executed by script) is the same as manual wiping all data partitions in the recovery.
Saves some clicking...

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 :/
Ok, with all of the talk about making sure folks do a full wipe before installing ICS, I would like to get some clarification on all of the different wiping methods and which is the best way...
I know of these ways:
1. Via custom recovery - you can wipe data, system, cache, etc.. individually.
2. Via holding Power+VolumeDown until bootloader text appears,, then wait until menu appears and select the Wipe Data option (instead of the cold boot option).
3. Via AARD SuperWipe full script
And then of course, there is the "Reset to factory defaults" in the OS itself...
Which is the best to use? I would assume the AARD SuperWipe full would be the most thorough as it recreates the partitions and everything (instead of just formatting them).
FOr users that have the ability, would an NVFlash of the OS be "more thorough" than CWM method?
Opinions/Experiences?
Thanks!
Don't use super wipe script. A lot of people reported having problems of some ROMs not flashing correctly after using it. There is no reason to use the "full" version anyway. It formats the /media partition(your internal storage partition) which you don't want to nor need to format.
Wipe Data in your #2 does pretty much the same thing as "Reset to factory defaults". They both wipe /data and /cache but do not touch /system.
The most thorough way of wiping that I use is via CWM.
I do all of this within CWM if I want to ensure a clean install of a new ROM and it has never failed.
- wipe data/factory reset
- wipe cache partition
- advanced / Wipe Dalvik Cache
- Mounts and Storage / format /system
I am not sure how NVFlashing a ROM does a clean install? As far as I know, it just flashes whatever it's told to flash. It wouldn't even touch /data if you were just flashing a ROM with it.

I've tried ALL of the above methods - all with the exact same results, to be honest...
Even if I revert back to honeycomb (even after a full wipe), I STILL exhibit the reboot issues (it's not just me - look around). This was NOT happening before with the exact same version of Revolver. This tells me that there is still yet something else that was changed during the ICS updates. We know the bootloader was updated - i'm now testing ICS with the old bootloader.
Other than the bootloader, what else could have changed?? Unless they upgraded the firmware on a particular device during the ICS update (wifi chip, bluetooth chip, etc). Other than that, I just can't come up with an explanation as to why Honeycomb won't even run properly anymore!

If you use the --create flag, nvflash will format ALL the partitions and then flash them. If you use the --download flag, it will just overwrite the partitions you send it.
That being said, I agree at your wiping method is more than enough. Most times, I don't bother wiping, especially data.

I've been using 4EXT Touch Recovery to wipe/format before flashing certain roms. Is there a right way on how to wipe/format using 4EXT Touch?
This is how I do it (correct me if I'm wrong):
1. wipe date/factory reset
2. wipe cache
3. wipe cache + dalvik
4. wipe dalvik cache
5. wipe battery stats
6. format system
7. format data
8. format boot
9. format all partitions (except sdcard)
10. format sdcard
11. flash rom

If you are flashing an update of the same ROM do "wipe dalvik cache + cache" (in case the Developer has not clearly stated that the update requires full wipe)
If you are flashing a new ROM use "wipe all partition (except sdcard)" it will do all the wipes from the wipe menu, no need to repeat it
And wiping the sdcard every time you install a ROM clearly does not make any sense, you are deleting all you pictures, music and all other files that are not related to any ROM you are using

I didn't know that "format all partition (except sdcard)" is the same from 1 to 8. I'll try using it from now on every time I install new roms. Also, I thought that wiping my sdcard every time I install rom is to make that rom fully utilized/functional. And that is why I back up all my pictures, music, and all other files in my laptop. Anyhow, thank you for your simple but very relevant response.
There are some ROM specific files on the SDcard but a full wipe (all partitions except sdcard) clears them too

This is noted... Thank you for all the info's... Greatly appreciated! :highfive:
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.

glad I came across this thread, was always wondering about TWRP being so used to ClockWorkMod
does format data also wipe my android os As well?
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.
