if i format system partition and install a new rom build would i loose my apps and mods?? please help
Format system means every thing under /system will be wiped and formated. Yes you will loose system apps and rom.
However your sdcard internal and external will not be touched.
Usually to install a new rom you factory reset, format system, wipe cache and dalvik. Then flash the new rom.
Your apps can be downloaded from google play or titanium backup if you backed them up.

if you only format cache & dalvik: no
if you also format system: yes
actually, you will only use system apps (hence the name), all your normal apps from Play Store will be there. But that's called a "dirty" install, and it probably won't work if you're switching ROMs, you'll need to wipe the data partition, which contains all of your user apps.

Whats the best way to do a FULL wipe of the device? including ALL user data/files/rom leftovers/battery stats/binary counter/everything!?
I am talking about as clean a slate as possible.
*2767*3855#
Extra wipe probably overkill .
Connect phone in mass storage mode and format the phone drive .
Boot to recovery wipe cache Advanced wipe dalvik cache .
Mounts and Storage format system data and sd card .
Use Odin to flash stock firmware as phone is empty .

wipe data factory reset and go to mount and storage and format system
To me complete wipe means complete not part wiped .
System Data Cache and internal SD card .
Though no need for wiping SD Card unless data corruption on it .

Wiping by means of formatting won't destroy all of the data, formatting an ext4 partition simply overwrites the file tables. With the right tools it is still possible to retrieve lots of your personal information from a re-formatted partition, including stored passwords, pictures, etc.

All the named procedures does not, don't they?
So either old bootloader and jig or easier use triangle away.
Erasing user data there is an additional option: settings-device-storage-erase USB-storage.
Full wipe. How??

I also do this when the instruction says "full wipe". Aside from this I also format the internal SD(to delete extra folders created from the previous ROM) since all my installers are inside the external SD.
Aside from the above instruction, I also read some posts that you have to mount to a specific folder(not internal/external sd) and clear/format that location. Can anyone confirm this? Thanks in advance.
I do this:
Wipes:
- Factory Reset
- Cache Partition
- Dalvik (Advanced)
Format:
- System
- Data
- Cache
- Internal Storage (No SD)

Could you care to elaborate on how to do the ones in bold?
What I normally do is that I mount points like /system, /data, /cache, /emmc and format all of them. I'll do all of this using ClockworkMod Recovery.

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.

Thanks, that makes sense.
not wiping before installing a new rom usually results to bootloops.
i see to it i wipe before installing another rom (unless i'm installing a newer version of the existing rom)

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)
Front to Back or Back to Front & Toilet Paper or Wet Wipes? Just Kidding!
When wiping via Factory Reset in TWRP what is the best way to insure everything is getting fully wiped except our external SD card. After I did a factory reset there was still everything on the internal sd card. Do any of you use the superwipe.zip?
What Procedures do you follow when switching Roms?

Factory reset wipes /data and /cache
after Factory reset, wipe System and you should be good to go on a new or fresh installation from zip. i dont think wiping boot is necessary but you can. so do
Factory Reset
System
Boot
Dalvik-cache is in /data so you dont have to wipe that.

This is the best, and also the quickest way.
Thanks for the help... I just don't understand why I have the following on my phone.
Sdcard - I understand that this is internal.
Sdcard2
Sd-ext.
Both the sdcard2 and Sd-ext have the same files on them, it has my music, some apk files, and my flash zip files. Now my poweramp player shows duplicate albums for all of my music stored on my external sd.
Any ideas

Sd-ext is or was the best way to move apps to the sd card. But with the new OS it isn't required if the app is made right

I factory reset twice, wipe dalvik twice and wipe system twice. I don't wipe cache since the factory reset does it.
Now that it was clarified dalvik is wiped with the factory reset I'll probably stop doing that. I just wish it clarified it since it specifically indicates the cache was wiped.

Hi
When you want to do a clean install of Windows OS, you all know that the right way to go is to format the primary partition first..
I was wondering: why can't we do the "same" in Android?
I've noticed that in CWM recovery there are many format options in addition to just doing Wipes...
So what if instead of doing the old Wipe data/cache and factory reset before flashing new rom, especially when migrating from Sammy to AOSP, we use the FORMAT function of the CWM recovery console?
So this bring up my new line of questions:
Which Formats are safe (as in terms of not bricking only, since we all know that we must backup first)?
Is Format data safe and recommended before flashing?
Is Format system safe and recommended before flashing?
Is Format SD card safe and recommended before flashing?
Does Format system erases the entire OS, meaning the ROM with it's kernel? If kernel is wiped does it mean that CWM will be lost upon next boot?
Same goes for Format SDCARD. Will this erase the entire internal memory? So the new ROM.ZIP should be placed in the external SD first?
I'd really appreciate if someone could answer all of the above questions
Many thanks
EB
If you don't have bad chip then all are safe. If you have bad chip then make sure you have safe kernel.
General steps before flashing a new ROM.
1. Backup your present ROM just incase
1. Wipe data/ factory reset
2. Wipe cache partition
3. Wipe dalvik cache (under advanced)
4. Format /system (under mount)
5. Flash your desired Rom/zips
6. Fix permissions (under advanced)
Notes:
- If you are moving from from an AOSP ROM to Samsung (vice versa), perform all the steps above.
- If you are upgrading / downgrading from one android version to another e.g ICS to jellybean or 4.0.3 to 4.0.4, also perform all the steps above.
- If you are upgrading from a Samsung ROM to another wipe the same android version, you may skip step 1.
- if you are upgrading your Aosp/aokp Rom with another with the same android version e.g 4.0.4 Aosp to 4.0.4 aokp, you may also skip step 1.
*******Important******
If you are presently running a Samsung based 4.0.4 Rom that is using Samsung based kernel e.g CF-ROOT or stock kernel, please flash Siyah kernel before performing any of the above steps. You will end up with ash unusable device if you don't adhere to this important information.

Just 2 more questions:
1. what about format Format SDcard (internal)? Is it also safe/recommended? What does it do exactly?
2. can any of the the above formats delete the IMIE? Where i it stored? On internal SDcard? Will formatting it delete it?

Formatting the Internal Sd card wipes all your data (music, photos, videos) on the internal memory of the phone.
Doing all those wipes doesnt affect the IMEI as far as I know...

1. You're first question has been answered in the post before mine.
2. About IMEI:
-Your IMEI is stored in your root folder /efs inn your system reserved partition.
-Flashing Roms and kernel shouldn't mess with this folder but sometimes it happens.
-most of the Roms Agnes kernels made by recognized developers will backup your efs folder before flashing.
-too be on a safer side though, you can visit the thread below to backup your efs (imei) folder yourself before messing with your phone.

My problem is that I keep thinking in MS Windows terms.. I was sure that "Format SDCARD" is the parallel to formatting the entire "Hard drive", just like to delete the system partition..
Know let me see if I got everything right:
Format system is like deleting the Windows folder - no more OS (ROM)
Format data is like deleting all user account = deleting the "Programs data" folder in Windows - no more app data
Formatting SDCARD is like deleting the "Users" folder including "my documents" - no more user private data
So by using the 3 above formats, there is no need to do a Factory reset. But what about Wipe cache and Dalvik? shouldn't System format take care of those two caches? Or perhaps Cache and Dalvik are to separate partitions?
And for the few last question, so I can finally declare myself an Android expert :
(1) Format boot is a very bad idea right? It will delete the bootloader, meaning one must flash a rom that includes one of it's own?
(2) Are all roms intended for CWM flashing come with their own boot partition?
(3) So if Format boot is risky, I can conclude that the CWM recovery must be part of the boot partition right?
Many thanks for all the help. Once I get all of this right, I will feel confidant to start flashing roms on my own for the first time (I already got my phone rooted and CWMed by flashing Siyah kernel using Odin

1) As far as I know, the boot partition is reserved for kernel. So, if you format it, phone won't be able to boot further than the initial Sgs2 logo. But it will still be flashable in Download mode.
2) If kernel is a part of boot partition, and most roms come with their own kernels, the you could say that the come with their own boot data.
3) If you format boot, you will also loose Cwm as it is a part of the kernel. Download mode would be still accessible as it is a part of the (secondary) bootloader which can be only overriden with Odin.
But again, I'm not 100% sure about this.

I want to erase all my previous data in internal storage. More specifically, erase the OS and data (app data, user data, media, etc), then I'm gonna flash new ROM.
But of course, I don't want to erase boot system and recovery system.

To install a new rom, you don't have to wipe the internal sdcard, just wipe data & cache and navigate to advanced and wipe dalvik cache, and then to mount and format system, then flash your rom, or use TWRP it's easier, press wipe then advanced wipe and mark (data, cache, dalvik cache, system) and swipe to wipe, then flash your rom.
Ps: all app data is removed from internal storage (data in sdcard\android) when you wipe data, so you don't have to wipe internal storage
Hello,
i really tried to find answers around before asking.
I have tryed different roms on my i9100, cm7, cm9, rr, miui. Now i have a tonn of folders from apps that are not even installed on my phone. Now what i want is to get rid of all the trash in my phone, like leftovers from apps i installed with previous roms and make a clean install of cyanogenmod 9.1.
How do i do that?
I would really appreciate any help. Tutorials, links, everything you guys can give to help me out.
Thank you
full wipe, install cm9, erase internal sd card
