hmmm will it delete all files my phone memory and also internal memory card?
don't think anything off the recovery menu touches sdcards in any way.
why not? /// i want to clear everything internal phone then put new firmware//
is that possible?
yup, just go under settings and format your sdcards, then wipe cache and perform a factory reset. then flash away.
I have few questions for wiping the phone?
A lot of time passed since I bought this phone, and there are a lot of garbage in sdcard and system itself? I changed many ROMs, and I want to breathe new life to phone.
I am interested in following CWM functions:
format /system
format /cache
format /data
format /sdcard
format /emmc
Will it erase everything and everything from the phone and sdcard, including the system?
Will this remove CWM and Root?
How to flash new system again, when I am not able to boot?
Is above procedure same as this, except that in this case, I am able to boot latest installed system?
- wipe data/factory reset
- wipe cache
- wipe dalvik
- format sdcard
- format emmc
What about code *2767*3855# , what is included under this type of wipe/reset?
Thanks
This just wipes apps. When you format /system it won't boot so you can only install a new ROM or restore a backup.. And no CWM won't be deleted..
Most ROMs format system automatically. But when you upgrade from GB to ICS you should format system and wipe data, cache and Dalvik cache.
And about the code, it's called a hard reset, same as wipe data in CWM.

How to restore backup when I formatted sdcard?
Is it safe to format emmc, and what is purpose of emmc?

Emmc is external SD card, I don't really know if it formats all(music and stuff and apps) or just apps. But i think formatting in CWM wipes apps only ..So better not format it .. no ROM requires formatting SD or emmc
And you should always save backups on your PC..but if you format SD I don't think it will wipe data

Now with the release of many JB leaks for our Galaxy Note, more and more people are starting to flash custom ROMs into their devices. However, many don't do a proper clean-up / wipe of their devices before doing so, complaining about supposed "bugs" that in fact are not real bugs, but just incompatibilities with previous app data and config left from the previous ROM or improperly restored from backups (TB etc.).
So, after facing that myself with the first ROMs I flashed, reading a lot of tips from the senior members, and experimenting different approaches, I came up with a method that I always follow before flashing a new ROM, which gives me less or no issues at all.
Pros: you minimize the chance of having issues when flashing a new ROM.
Cons: you have to manually reinstall your apps (can be somewhat automated from Google Play) and reconfigure everything.
Pre-reqs: I'm assuming you have CWM installed and know how to use it, and are not a complete noob. If you don't, search the forums and read the guides. Read this guide fully and make sure you understand everything before proceeding.
IMPORTANT: ONLY wipe your device if you have a SAFE (BRICK-FREE) KERNEL. Check your kernel and search the forums. Don't proceed if you are not sure! I'm not responsible for any bricks, unexpected issues that can happen to you or personal data loss because you forgot to backup that! If you want to stay safe, don't want to experiment with your cell phone, it's critical you have it working everytime, stay with the official Samsung ROMs updates you get OTA and don't proceed with this how-to.
How-to:
1) Boot into recovery and perform a full backup (a.k.a. nandroid) to your internal or external SD card.
2) Reboot, and create backups of personal data needed from your apps in your internal or external SD card. For instance, I backup data from apps which are not cloud-based; they usually have a "backup" menu for that.
3) Plug your device into your computer, and copy everything you need from your internal and external SD cards (including the backups done in 1) and 2)). Don't forget your pictures and MP3 files.
4) Delete any apps and data from your external SD card. Leave it as clean as possible (it's OK to leave personal data such as MP3s, pictures etc.).
5) Copy the ROM you are about to flash to your EXTERNAL SD Card (don't copy to internal, because we are going to wipe it).
6) Boot into CWM Recovery and do the following wipes:
6.1) Wipe data / factory reset
6.2) Wipe cache partition
6.3) Advanced -> Wipe dalvik cache
6.4) Mounts and Storage -> Format /system
6.5) Mounts and Storage -> Format /preload
6.6) Mounts and Storage -> Format internal SD card (make sure you know if your internal SD card if /emmc or /sdcard; see below!)
7) Install Zip -> Flash ROM from your external SD card.
8) Wipe cache partition again.
9) Advanced -> Wipe dalvik cache again.
10) Reboot
11) Don't restore anything from Titanium Backup. Reinstall and reconfigure everything from Google Play. I never tried but I think that if you just restore user apps, it should work. Just never restore system apps and data. The backups you created in step 2) and copied to your computer in step 3) can be safely restored from within the apps themselves.
Now you may ask why we format the internal SD card. Many apps store their configuration and app data there, so this way we ensure no old data and config are there which may be incompatible with the new ROM. In fact it might not be that important, since it's only related to user apps, but I prefer to clean everything before flashing a new ROM.
How to find if your internal SD card is mounted on /emmc or /sdcard in CWM Recovery:
1) Boot into CWM Recovery.
2) Install Zip -> Choose zip from internal sdcard. In the top you can see where yours is mounted (/emmc or /sdcard).
3) This is the partition you should format in step 6.6. Pay attention to not format the external SD card, because the ROM zip file is there!
If you still have issues after flashing a new ROM, try to reflash it without any wipes (i.e. just do step 7 again).
Hope it can help people with their flashing!
Good job
Is it any better to just install user apps from google play and then restore just the data from TB?

No..the main purpose of the thread is to remove the incompatible app data and system data
Useful.

6.2 ---> unnecessary, because factory reset wipes user data and cache
6.6 ---> how on earth does formatting internal SD card help flashing any Rom?
8) ---> unnecessary, because your cache is already wiped
9) ---> see above
6.2) True, thanks for pointing out.
6.6) Some apps, including ones that usually give strange issues between ROM flashes like SNote, leave data there which may cause incompatibilities with a different version. This incompatibility is just a guess; as I said in the original post, it may not be that necessary to format the internal SD card, but I prefer to make sure there is no old data at all floating around, and this recommendation can also be useful when people are going to sell their devices (many think that just a factory reset is enough).
8) and 9) Is it possible that a new ROM can come with stuff in cache and dalvik cache, say, from the developer testing/cooking environment? If it is, can be useful to clean it again after flashing. Otherwise, I agree, it can be skipped.
Yeah total clean scenario is best. In my opinion. So also SD, but never efs

I too do things that are not necessary, I have a ritual when doing a deep clean lol
It involves things like the above method, but i do it twice.. No harm in that is there !

Thank you very much. I will do this like you say.
I have CWM v6.0.1.2 and I don't have format/ preload. What can I do?
You can try to proceed without formatting it, or you can first flash a kernel with a more recent CWM. Always a safe kernel, of course. After flashing it, you can just select "reboot recovery" from your current CWM to boot into the new CWM. I'm not sure if the absence of /preload is due to an old CWM, or it's because you don't have a /preload partition. Anyway, trying a newer CWM won't harm.
i follow this guide , considering that i'm a noob it mean that is written really really clear. Thanks for all your job . i have a clean cooked rooted cell now.
error preload
Hello, I got error when formatting preload
it is said "make_extf4fs failed on/dev/block/mmcblk0p9
and when i'm trying to format/scard it pop up some type format

Hey bro,
i forgot to do step 9
9) Advanced -> Wipe dalvik cache again.
Phone is working fine, but just curious. will it have any effect ? or will it cause any problem later ?
Howdy.
I was wondering what's the correct procedure to do a complete, total data wipe of the phone.
When I do a full wipe, cache wipe and a dalvik wipe, all the data still stays intact on the phone. I want to start anew.
Also, if possible, I'd like to fix the external_sd bit so it's actually the sd card and not some directory on the phone (if I recall this was a JB "upgrade"?)
I am currently on a PhilZ Touch Kernel running LSC.
Thank you!

when I want do a full wipe, and start from scratch with new custom rom I do the following:
-make sure that you are on safe kernel (which you probably are)
-make sure that your new rom.zip is on the external sd card (because you will format your internal sd)
-backup your pictures, music etc... from internal sd
-reboot recovery
-wipe dalvik cache, wipe cache, wipe data,
-then go to mounts and storage and format: cache, data, system, preload, emmc(is your internal sd card, first do backup of important stuff), and that is enough, be careful to not format external sd (where is your rom)
-thats enough wiping
-install rom.zip from external sd,
i hope that helped
i dont know what you mean by external_sd is directory on the phone (maybe because of folder icon in stock file explorer "my files"). Can you describe it little bit more
Najlepsa hvala
Looks like the sd issue got fixed with the new rom as well. Awesome.
I need new/fresh/clean install of 7.1.1 but I cant wipe sdcard. Something like factory reset but no wipe of sdcard. Is it possible? Aroma installer has offered such option - clean or dirt flash, but now I had only 711 factory image.
Any idea?
------ EDIT ------
maybe TWRP wipe data, cache and dalvik but not internal storage is a key?

Yes.. That's the key. "SD Card" is your internal storage. Don't wipe that.

Building on your answer, if I want to really start fresh with Android 7.1.1 does it hurt anything to wipe internal storage?
Follow the instructions here: https://forum.xda-developers.com/showpost.php?p=70516840&postcount=2
You wouldn't need to flash the "radio" partition if you are just cleaning up an existing 7.1.1 install. This will give you a clean system, but maintain your /sdcard data.
