I see people saying that wiping data, cache, and dalvik is considered a full wipe. But isn't that incorrect? Wouldn't formatting the system, data, and cache be considered a full wipe? If using TWRP, under advanced settings or options is a an option for formatting. When choosing to format system, data, and cache partitions, isn't that what people want to do when doing a "full wipe"?
Formatting system will clear dalvik so I'm just confused when people say to wipe fully, and by that they say to wipe data, cache, and dalvik. That's nothing, but a factory reset because all that does is erase your data, and leave the system intact with whatever you installed into the system such as kernels or tweaks.
So my question is, what do you guys and gals consider to be a full wipe?
I use the advanced> format menu to wipe each invidual partition, including /system. I myself have always wondered this as well seeing as to most people, a full wipe is considered a factory reset which includes data, cache, and dalvik cache. I wipe each individual partition including system and thus never have weird problems that others complain about.
I've wondered that same thing, cause some say wipe everything and then some say format ur system first. So which is? Which way is the Proper way?
The proper way is formating
System
Data
Cache
Formatting system clears dalvik. I'm just confused because people keep telling others to do incorrect things when they say full wipe. I just want to know what the users think when they use the term.

Well I use the super wipe zip, I think that's what it's called, to wipe my phone then I was just formatting my system. I wasn't really sure what people wanted. Like I said one says wipe and one will say format, but thanks for telling me the proper way.

A zip? You'll be fine if it does what it is supposed to do. But if you do it manually, this is the correct way.

I just looked and it's the infected wipe is what I've been using but I guess I'll start doing it the proper way then.
I have always considered wiping data, cache, and dalvik as a full wipe. And formatting every thing as, well, formatting lol. I have never formatted any of my partitions when installing new roms, can't say I have ever had an issue either.
But you certainly bring up an interesting point.
For those that are confused: "formatting a partition = "wiping" a partition.
format boot (contains kernel,ramdisk,etc.)
format system (contains base OS,apps and framework,etc.)
format data (user apps,accounts,batt stats,dalvik,etc.)
format cache (lots of stuff, lol)
/full wipe
side note: every ROM zip I've ever seen formats system and boot, so usually if you're flashing a ROM (and feel like wiping) it's totally fine to just wipe data and cache and then flash. If you're flashing over (no data wipe) then you'd want to wipe cache and dalvik, same for a kernel, that gets rid of cached stuff you probably don't want on boot. Especially dalvik since it contains a classes.dex for all your apps, which could contain old data you don't want in your new ROM. These dex files are built during the bootup, so it's safe to wipe them out, that's also the reason a bootup takes a lot longer after a dalvik wipe where you haven't wiped data.
hope this helps

Im sorry if this is such a nooby question but on some custom roms it recommends to wipe /system. What does this do? And what do you lose? When I usually go to another rom I wipe user data, cache, dalvik cache and battery stats. I never had any problems by doing so. In my case I never saw where to wipe /system I found out it was under mounts and storage in recovery a few days ago.

This is wrong....
The /system partiton is where Android itself gets stored. As in the system apps and framework. It is recommened to wipe it when changing to a *non-wipe* firmware just in case some files are different and get left over from the previous rom.

not wiping before installing a new rom usually results to bootloops.

As was posted earlier in the thread, wiping system basically wipes the rom/os and system settings. Your user data, apps, pictures will not be wiped. If you rebooted after wiping system the phone will not work, however you could wipe system then flash an update of the same rom and reboot and you should be fine(depending on the changes between rom versions). This is basically referred to as dirty flashing. FYI, most custom roms have a script which wipes system, cache and dalvik/art cache automatically preserving only /data(user apps and data)
Back in the Cappy days, before I'd flash a ROM I'd always use the OneClick back to stock and do a master clear. Always gave me piece of mind that there wasn't anything lingering around that's going to jack up my ROM flash. I really don't use that many apps and can dump my pix/music/vids back on with a quick drag and drop so it wasn't a process. Is there an equivalent of a 'Master Clear' for the SGSII? I'm pretty sure all it did was do a format of the internal SD, so is the CWM format just the same?
Yes. I always do a factory reset plus clear cache. If you do those before you flash it you will be good to go.
It doesn't delete any files from the USB storage.

Right, but I want to wipe all user data too. Can CWM do the same thing that the ODIN OneClick Master Clear did?

master clear is not necessary.
in CWM, if you select:
wipe data/factory reset
that will wipe all of your /data and /cache partition
you can format SD card also, but it is not needed.
there is nothing outside of /data, /cache, dalvik cache, and /system that could 'mess' with your newly installed rom.
/system will get wiped when you load a new rom, and every rom script should include formatting dalvik-cache as part of the procedure. wiping data should be up to the user, because if moving from version 1.2 to 1.3 of the same rom, there should be no need to format data.....
the cappy (GS1) was different. the one click to stock was to reset the partitioning scheme that voodoo performed and to set the filesystem back to factory for the next rom flash.
with the GS2, samsung realized that RFS was a horrible filesystem and they went with the standard EXT style formatting. one click and master clear are a thing of the past now. you can try to justify the 'want' for a master clear, but i can assure you, nothing is lingering that can jack with your flash

Good point about the file system difference. Just remember stuff not acting right jumping from ROM to ROM with the Cappy and wanted to avoid that on the SGSII. Thanks for the info.

You are awesome dude! Just got my s2 last night and spent a majority of it going through forums trying to find an Odin one clickk to stock like the cappy had. Was nervousness about rooting and flashing cause of the flash counter deal, and if I Bork my phone, how to get it back to the original condition. I still have a ton of reading to do. But I feel better after reading posts like these very informative:-D

$1.25 jig, Root/ wipe cache, wipe data/factory reset > install ROM/CWM/kernel etc. happy times.
I have TWRP 2.2.1 installed, unlocked bootloader and rooted, I want to install a new ROM but I want to do a full wipe as per the installation instruction.
In the Wipe Menu I see 6 different options. Which ones do I wipe for it to be a full wipe?
Cache (I can probably wipe this)
Dalvik cache (I can probably wipe this)
Facory Reset
System
Exernal Storage (I probably don't need to wipe this)
Internal Storage
Thanks,
Richard
A full wipe is factory reset.

Not true, A factory reset wipes data, and cache. A true full wipe is System, data, and cache. When doing this I usually click on factory reset twice and then system twice

And I'd throw "System" in there for good measure.
Thanks guys. Worked like a charm.
There is a mod you can flash that does the same thing called superwipe
Sorry to bump this, but factory reset WILL NOT erase media on phone, right?
No, it will not. ONLY a SD card erase will wipe the media.

I use swm6180_superwipe between flashes. Not sure that it's necessarily any better than using the wipe option in TWRP, but here's a link. https://db.tt/lAVSMRwY
I wish I could remember what thread it was from so I could link you to it directly, but it you find it make sure you thank swm6180.
sorry to resurrect this yet again but dose swm6180_superwipe still work? i used to use one on my galaxy s2x but that one no longer works i have been told.
full wipe!" i must to select all ? :dalvik , data, internal storage, cache, usb otg )? and " system " no correct?
I assume the advantage of using the full wipe zip is how fast it works. What else is recommended to wipe before flashing a new rom. What I have been doing is flashing the wipe zip, then formatting system, cache, and data, then wiping dalvik cache. Is all that necessary? Should I also be doing a full wipe/ factory reset? Thanks in advance.

I believe the zip you are referring to is Bills fullwipe zip. It wipes everything needed to flash a rom except dalvik cache. So, flash the zip, wipe dalvik, flash your rom.

Nope, that's the three it wipes. And yes a few seconds is normal. Only thing you might wanna wipe is dalvik.
But, I mean there is the full wipe/factory reset, and then under mounts u can manually format each one. What is the difference between formatting and wiping?

For our usage, not much difference.. But technically, wiping referrs to 'deleting' everything there. Deleting makes something disappear, but doesn't make it nonexistent. It just tells the system that this space can be used for other things now. Until the the given sectors where the data resided are used to write something else, the deleted items technically still exist. Formatting, on the other hand, goes through every sector and writes over it with 'blank' data, securely making the data unrecoverable (for the most part).
How can you relate this to your phone? Well, if you are installing a new rom, wiping the data is sufficient. If you are getting rid of your phone for whatever reason, formatting is suggested.
Ok, thank u for the clear explanation.
I have a quick question regarding TWRP. I have installed a rom that i'd like to not use anymore. However, when I restore, all the system files are still there (I know this because they still pop up as a deodexed version.)
Anyways, I was wondering if it is ok to do this in TWRP
-Wipe cache/factory reset
-Wipe system data <--- that is what 'm really wondering
-Restore from my backup that I made that has the proper system files I want.
Im looking at it right now and factory reset says wipe data and cache, so I am guessing that option kills two of the 3 standard steps apart from wiping dalvik. Now the wipe system, Im not sure; but for wiping the normal 3- do factory reset, cache, and dalvik cache
All wiping or formatting /system does is wipe your current rom. I always do it before flashing or restoring anything just to be totally sure no lingering remnants of my previous rom remain and I've never had any issues doing so.
Sent from my SCH-I605
Wiping system before flashing a ROM is likely pointless, unless the ROM has a poor updater script that doesn't format system in the flash process. If it didn't format, the install would end with an error. If it was just deleting recursively and came upon a file it couldn't delete, it'd still end with an error. Formatting it before flashing isn't going to wipe anything out that wasn't already getting deleted as part of the updater-script formatting/deleting.
Also, if you perform a factory reset in recovery, you don't then have to go and wipe cache and dalvik cache as well. Factory reset already formats all three of those. Wiping cache also clears out the dalvik cache, since that is where the dalvik cache resides. Wiping 3 times is also a waste of time, as again, do you expect things to be left behind when it is formatted?
Do people frequently experience files being left over on flash drives and other removable storage devices when they format them that this whole "lets format it 3 times to make sure it's gone" craze started? Every time I've ever formatted something, as long as the process completed successfully, all the files were gone. The same goes for deleting a bunch of folders. As long as there wasn't an error, all those files disappeared too.
