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?

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

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.

Hello, I got error when formatting preload
it is said "make_extf4fs failed on/dev/block/mmcblk0p9

As stated in the title, does flashing a new ROM erase data on the built-in flash drive such as contacts, apps, appdata, music, videos, pictures etc?
I'm rather new to ROM flashing.
short answer: Yes with an If, long answer: No -- with a But...
When flashing a new ROM to an Android phone its a good idea to do as its creator has advised and wipe data/factory reset and wipe dalvik cache all via ClockworkMod recovery, that way there is no additional bloat ware or old system data to gum up the works,, anything stored on the phone (contacts/system data) is erased anything on the 'internal storage' (8GB or so on the XL) or memory card is spared, so anything backed up to there will be safe
Its worth making note that when first installing a ROM, most if not all work on A2SD/ADSD+/+ etc, this is where your given the option to store app data on the memory card, in devices where you can take out the memory card you will need to format it (via ClockWorkMod recovery) and sort out the size of your 'hidden' EX3/4 partition that app data is stored on. formating and partitioning yor memory card wipes everything on it so back it up to a PC before doing anything!
Additional Note: Since the XL has internal storage make sure you get everything you want off it first then when we have CWM working on the XL format the crap out of the internal storage and have fun!

Ahhhh I see. So if I want to flash a new ROM, I have to back up everything on my own then manually re-enter them.
Thanks for enlightening.
Pretty much yeh, always a good idea to manually do a backup every now and again,, once you have your ex3/4 partition apps data will be restored when you reinstal the app, also Titanium Backup w/root permissions on a fully ROMd device will restore data in the same way too (if you backup with root access the first time etc)
hi,
i'm usin ra passion 2.2.1 and wan't to use a2sd from ics 4.0.3 evervolv. how can i create a part ext4?
Google:
"a2sd partition sd card".
Enjoy.
Try 4EXT recovery www.4ext.net
I think its the easiest way to create partition.
Or else you can do it in pc via partition managers(i use minitool partition wizard)
You can google it and also can search in youtube for video tutorials.

thanks for your help, i've done it in recovery.
one question is left:
what happen if i format the partioned sd-card under windows and do a full wipe in preparation for installing a new rom. i've read sd-ext even survive a full wipe? what does that mean? stays the partition untouched when i format the sd-card with windows? and what about the apps in the partition? are they still there even after a full wipe and can i use them after flashing a new rom out of the box?
Glad u succeeded in partitioning
Now if you format the fat32 partition in windows using those partition tools doesnt affect ur ext. Ext stays untouched but all the data on fat32 will be wiped(so backup first to pc)
If u want to merge there is an option called merge for that.
There is an free windows software called sdformatter, that formats the entire sdcard(fat32+ext)
Hope i helped a bit :thumbup:

ok. i wan't to format it with the windows internal function via right click. is it the same and the ext4 stays untouched?
Full wipe in recovery wipes SD-EXT too.

when i flash a new rom i use the format.zip form the xda user temasek which wipes system, boot, data and cache. so is sd-ext untouched when i use this file?
You insist on not listening and/or not understanding.
When you select "wipe data/factory reset" in custom recovery, EXT partition IS WIPED COMPLETELY. It doesn't stay.
I believe the same happens when using temasek's script, never bothered using it, so I can't say with 100% certainty.
If you don't wipe your phone and install a new ROM - be prepared for crashes of anything to everything, unless you install a ROM which is 100% compatible with what you have already - the next generation of the same ROM, usually.
If you're using A2SD and don't wipe EXT partition - you'll have crashes as soon as you boot, since system apps' data will be there (and wrong).
To keep your apps and their data, use one of the backup apps available in the Market, like Titanium Backup.
as Jack_R1 explained its always better to wipe everything(system,cache,dalvik n sdext) to be on safer side to avoid crashes n FCs.

Temasek's Extreme Wipe does Data/System/Boot partitions but don't remember seeing ext in the list
However, as alluded too, I would format all outside phone with sdformatter or I think gparted, although never used that one
I thought I read a long time ago Windows formatter not recommended and do a full wipe not partial with whatever you use
Back up sdcard first
also, I believe you can use the Alignment Cool zip to get ext 4 from 3 on Amon and not lose anything--still backup
you do know MeDroid uses Ia2sd and different from a2sd on implementation
You don't need to wipe the regular FAT partition on SD card between flashes, because there's nothing there that loads automatically. And "wipe data/factory reset" option in recovery also wipes /sdcard/.android_secure.
hey guys, thanks for your answers i will keep them in mind.
edit:
one more question:
if i uses temaseks script and the sd-ext is untouched and i flash a newer version of my rom, are the apps then still there after flashing and booting the updated system? or is there another step i've to do?
No, the apps aren't there anymore - or to be correct, the apps are there, their data is gone (because the app data doesn't reside on EXT partition, unless you use specific mounting methods).
When you flash an updated version of your ROM, just don't wipe anything at all unless the instructions specifically mention having to wipe before installing that version. That means - don't execute temasek's script at all.
Hi, apologies for my Noob questions.
I have been flashing various ICS Roms and kernels over the last few week - great fun etc. etc.
My SGS I9000 internal Sd/storage is getting pretty full with (probably useless data/folders/backups etc.) and I do not know what to safely delete....
I have started to get regular automatic reboots (3 or 4 per day) which I believe is related to these past installations...
Anyway, I would like to clean/format my phone so that I can start again.
How do I do this - what are the procedures
What will I lose?
What will I end up with - GB or ICS
What should I back up before hand?
Can I flash the latest ICS Rom or will I have go through the procedure of rooting the phone like I did when I was on GB?
Sorry for all these simple questions but I do not want to mess up my phone due to ignorance.
Thanks in advance for you help
Sorry, what is GB?
I recommend backup ur pics and music and do a sdxard and sd extrrnal back up (too have a clean phone).
Im using Cyanogen ICS 4.0.4 and works ok.

Thanks Nikhilonlive,
Will the formatting clear all the "redundant/useless" folders etc. on my internal SD so if I looked at it before reflashing the Rom it would look pretty clean.
I would like to start with all the rubbish gone and only files/folders relating to latest Rom & my current Apps.
I hope that this makes sense...

I did the following to fully clear my SGS:
Copied all important stuff e.g. Photos, Maps, preferred Rom to my external SD card - removed SD card for safety.
Back up SMS & Call log to gmail with "Backup to Gmail"
Then within Rom Control:
- Factory Data Reset/Reset Phone (tick erase SD Card) etc. etc.
- Within Storage - "erase SD card" (there will be nothing left on the SD card)
Put external SD card back into phone
Then in Recovery mode:
- Wipe data/factory reset
- Wipe cache partition
- (within Advanced) Wipe Dalvik cache
Install Rom
- Install zip from sdcard
- Choose zip from internal sdcard
- Infinitum-v2.1.zip (in my case)
- When installation is complete go back to "Reboot system now"
- Reboot system now
You should get the normal set up instructions to log into gmail etc.
- Apps should automatically install
- Restore SMS & Call log
- copy across maps etc. from external SD
This may be a little extreme but I wanted a very clean phone
My phone was clean, it only had data, apps & Maps that related to my latest Rom etc.
Stats after above:
Internal storage - Total Space = 1.85GB Apps etc. 281MB, Available Space 1.58GB
USB storage - Total Space = 5.63GB, Apps etc.264MB, Maps 1.286GB, Available Space 4.08GB
If I have done some unnecessary steps, please let me know.
How do I "clean" my phone after flashing different roms. I explored the contents of the root directory ('/') and I could find the files/directories which I suspect are from earlier roms that I had used.
I thought flashing stock rom through ODIN would delete everything related to previous rom but looks like that is not the case. Should I use reparttition option in ODIN with pit file to achieve this ?
What i do when i get to this point is copy everything off internal sd card onto a folder on my pc and format internal sd card. Then do all the normal clear data, cache, dalvik, init'd and ns tools and finally flash new rom...

You'll want to go into CWM prior to flashing and format /system as well as 'wipe data/factory reset' (this will format the rest). Optionally you can format the sdcard, but with the above you'll have a clean system.

Thanks..I believe format /system will format /system (i.e. cleaning up system directory in root '/'). Does it mean that I don't have any other leftover in the root directory ( '/') ? Every thing that a rom & kernels install will be wiped after formatting /system ?
If you don't format sd card you still going to have those left over folders and files from various roms and programmes you have installed and removed. This stuff isn't necessary to remove but thought that is what you were asking about.

Essentially, /sdcard is the only thing you don't need to format. Apps store files here, but they aren't within the system and won't affect performance if they're left over. You can manually delete them if you no longer have the app, or you can backup things to keep and then format it as well.
Otherwise, you'll want to format everything (except for boot).
Init.d is a folder which contains scripts that run at boot. Wiping this prevents problems that may occur from leftover scripts. NSTools is an app that has settings that run at boot, such as overclocking, undervolting, etc. It is also advised to wipe these settings as to avoid conflicts when flashing new kernels, ROMs, etc.
But formatting /system and wiping data/factory reset (which formats the rest of the Androids operating system) will allow you to have a clean install of any ROM. The leftover app files on /sdcard are negligible and can be deleted.
After I installed the Safe Kernel Hydracore and Reboot to recovery (vol.up+home+power button) I select wipe data/factory reset & wipe cache partition and even go into Advanced and did the wipe Dalvik cache and after I installed the latest Cyanomod 10 and Gapps and reboot the phone, I still have my old folders like before with maps, games, etc...
When I looked in my Main Storage of my Note (/storage/sdcard0), I only have 3.5 GB free. And like I said, I can still see my old games, apps and maps folders in my main storage which took up a lot of space and I only have 3.5 GB free. Do I have to manually delete every folder in the main storage and go back to recovery and do everything over? Could this brick my phone?
How can I completely wipe everything in my main storage?

Wipe in cwmr does not clear internal storage, for that you need to format internal SD. Once on safe kernel you can easily format sd and there is no risk in it. Just format it in settings/storage but make sure to move required files to external sd (like pics or music)
Sent from my GT-N7000
Does it suppose to format your internal sdcard? The answer is NO. Format it by going to settings/storage/format internal memory.

Alternatively, as I find even a format of sd sometimes does not do a proper wipe, connect phone to pc as usb, then manually delete all files on SD.

Think you are all wrong guys.
He wants a factory reset, not manualy delete folders and files.
There are a lot other stuff that remains on the Note, registry, hidden files...etc.
There is only one simple way to do that.
Because all "new" kernel have the option to format emmc disabled, remember the Note brick times.
Flash the Abyss 4.2 kernel, restart in recovery, do factory reset ( it works ) and full wipe, flash an safe ICS kernel or flash the whole new ROM of your choice.
You are done.
Remeber to restart in RECOVERY afte flashing the Abyss 4.2 kernel for factory reset.
The other, difficult, way is to flash a rootable GB ROM with PC Odin, root your Note an after that, you have a clean, almost virgin, Note for flashing the newest ROM of your choice.

Ergo => formating internal SD doesnt touch the system => doesnt do "Factory reset"?
Right?
Factory reset with "unsafe" GB kernel format system AND internal SD.
After that you can manually mount system and format it, also all other system partitions, from unsafe kernel.
But after formating system, data, dalvik and all other system relevant partitions from any "safe" kernel you will find all your data, passwords, old programm entrys untouched.
Fact!!!
Ever installed again your navi software after doing full wipe and manually formating all system partitions from safe kernel?
After reboot there is nothing, but install your Navigon and it will find asap all your maps, account and everything else.
All the data are present and this is NOT Factory reset.
There is not problem WHAT does "Factory reset" and "format system" but it is VERY, VERY, VERY important from what KERNEL you do this.
Safe or unsafe GB kernel.
And again, deleting all data from the phone is only possible with unsafe kernel or flashing original Samsung firmware.
And this guy above did a full wipe with safe kernel and finds all his data untouched.
And again: a clean Note is only possible with unsafe GB kernel or original Samsung firmware.

You're talking bonkers mate. A factory reset only resets the system partition. It does not include internal sd card Nov matter what kernel you're on. You have to specify a separate operation of wipe internal sd card for that. Kernel type doesn't make a difference.
