[Q] Difference between Factory Data Reset vs CWM Wipe

What's the difference between doing a Factory Data Reset and doing a wipe using CWM.
I'recently rooted my Note and now have CWM installed.
I plan on trying a few different ROMs (both newer stock ROMs and eventually custom ROMs) and read in most instances to per a wipe before upgrading.
I was wondering which wipe to use.
Also, if I install Titanium Backup, will it save everything including Contacts, Network settings, icon layouts, webpage favorites, appa and everything else?
Thanks

Cant say surely about the difference between factory rest of data and CWM wipe. But can surely say to flash any rom you need to CWM wipe all the data and cache and dalvik cache from the recovery.
And Titanium Backup is for backing up and restoring all your apps and their associated data and market links. It doesn't backup contact (should auto backup to your google account or use any contact and sms backing app from market like - https://play.google.com/store/apps/details?id=com.idea.backup.smscontacts&feature=search_result) or
layouts . Icon layouts you can save by going to the backup settings of the launcher you are using and favorites you can again backup on your sd card.

CWM recovery wipe cache, is just wiping cache files not data
while CWM recovery wipe data n Hard reset from setting - privacy - erase data(factory reset) is same
CWM function is useful when you unable to boot device normally.

Where is dalvik cache located ? Because if it's in the data or cache partition, then I don't see why I have to wipe dalvik cache after wiping data/cache...

System apps' dalvik-cache in /cache
Data apps' dalvik-cache in /data
Hence just by clearing the cache you clean the /cache space of system apps and not the dalvik cache of data apps.
So you require to do both - clean cache and clean dalvik cache.

Factory Reset will change your Android ID. Some apps with custom DRM may stop working. Factory Reset is also incompatible with some ROMs and causes some apps/files installed by CWM flashable ROMs to disappear.

I think both are same. Both format data and cache partition.
(that is why devs warned not to perform FDR on affected kernels)
With FDR you initialise the command from booted phone.
CWM Wipe is what you do from recovery mode.

How come I cannot wipe clean my Note?

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)

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.

I think the first two guys answered correctly.

Factory reset = format internal SD with safe kernel??

Factory reset only formats system, so doesn't touch internal sd card at all..... Fact.

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.
Formating system from a safe kernel is NOT enough for a clean phone.

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.

thats true.. u need to load other partition on a safe kernel and format manually.. but GB recovery does the same as well

[Q] How to install correctly?

Hi there!
How is the correctly way to reinstall "CM10.1 native emmc" on my nook? I have have installed 10.2 and want to delete all user data. I´ve tried, but real racing 3 has the right version, after installing.
I have tried following methode:
wipe data/factory reset
wipe cache
wipe dalvik
--unter mount & storage (auch Recovery):
wipe/format cache
wipe/format data
wipe/format system (am wichtigsten!)
wipe/format preload
Preload was not to find in my cwm.
Then I flashed the new file an d wipe cache wipe dalvik cache.
My personal game data was still on the nook.
Can anybody tell me, how to install any version of cm by deleting all data?
Greetings from germany (please forgive me my bad english)

Yes go to mounts and storage and format 'data and datamedia'. That gets rid of your media files too (where that game data is stored).
Sent from my Nook HD+ running CM10.1 on emmc.

[q] clean installation!

Hi,
I previously install CUSTOM ROM via RECOVERY. Then I install back STOCK ROM via RECOVERY. After the installation of STOCK ROM, I found that in internal memory that are some application from previous ROM. What should I do to remove it? Do I need to install stock ROM in FLASHTOOLS? If got any solution please help.
FYI : Before I install new ROM I did this Wipe Data, Cache and Dalvik Cache.
Sorry for my bad english

If I did that, will my ROM be missing too?

No, just like a factory reset with the internal sd wiped.
If you want your rom to be wiped go into recovery and do wipe /system

Your Rom will be resetted. Back to factory settings. All your data will be lost, so do a backup if necessary
Edit: sorry too late

Do a complete wipe with TWRP before installing new ROM.
Dalvic cache + cache + system + data + android secure
After doing above, flash your respected ROM.
PS: Your not wiping 'data' that's the reason for the remaining apps.
