Does Factory Wipe and Flashing the ROM with Stock ROM, COMPLETELY clear all previous contents inside the ROM?
Or does one also have to FORMAT the System Partition from the Recovery to ensure everything is GONE?
Or Would this be redundant?

Might be a stupid question, but anyone know how to do this? I want to only keep PSX And neo with no other data on it (Such as games that require downloaded data, apps and etc). Wiping data on CWM doesn't wipe everything (Yes I did cache and dalvik as well), would wiping the sdcard wipe everything and leave the ROM? Hopefully someone can help, thanks
Also, if the only way of wiping brings me back to stock/unrooted, would I still have CWM installed to install custom ROMs and such still?
These are the wipes you are looking for:
1. wipe data/factory reset
2. wipe cache partition
3. mounts and storage > format sdcard
4. advanced > wipe dalvik cache
That should leave you with a empty/clean internal sd card, no data (apps, settings, etc.), and your current rom and kernel.
if you want to completely wipe everything and go back to stock Android, just use one of the toolkit and flash stock image. it will wipe everything in the phone.
Or just fast boot the images including the userdata file it'll erase the entire phone memory. Toolkits are convenient but you should know how to use fastboot too it saved me when my recovery wouldn't boot and there was no ROM on the phone.

Alright guys I feel very nooby asking this but this is my first device that doesn't have a sd slot. Is there a way to flash a Rom without deleting the download and titanium folders?
My steps prior to flashing are
Wipe data, cache, n dalvik
Flash Rom
Then wipe cache n dalvik again
But if I wipe data then the Rom zip would be deleted before I can flash it?
Please help me on this thanks!

Hi,
Make only wipe data/factory reset, wipe cache partition and wipe dalvik cache, tat's all then flash your rom and reboot.
Don't wipe anything related to sd card/ext sd card or internal storage so you keep all your files in your "sd card" intact.

This won't happen on your LG G2. Even when using CWM you can see it is looking for an external SD card in the command line when doing a Factory Reset. You're internal SD card is never touched.
When you flash a ROM just:
Factory Reset
Flash Rom
Obviously make a backup first if you're worried, and you may need to flash Gapps depending on the ROM you flash.
understood, thanks guys
Hello people. Just wanted to ask how is the right way to wipe when flashing a rom WITHOUT losing the rom (wiping internal)? In CWM i just factory / reset data then thats it then clear cache and dalvik cache. In TWRP do i just need to swipe when the screen says "Most of the time this is the time that you need" when i will flash rom? Thanks for guiding!
anyone?
1. factory reset
2. advance, wipe system
thats all for me, works everytime... just make sure to wipe cache/dalvik after flashing zip files be it roms or gapps or whatever :good:
The default "most of the time" option is a fresh reset of the phone. it wont wipe the ROM itself, but all the data will be lost and you start over. Wiping system will remove everything, a ROM must be flashed after wiping system.
So before i flash a rom i wipe the "most of the time" then advanced format system? right?

true that... sorry for misleading initially, format system only applicable if you wanna have clean install of new rom

No need to use format system unless you are installing a fresh ROM. Format system will remove everything from your device (other than sdcard info and all that). So you get a clean slate.
If you just want to flash an update to the same ROM you can either 'dirty flash', which I usually just wipe cahce/dalvik then flash the ROM and reboot, and you save all your user modified things, or you can wipe system and install the ROM. You lose everything that way so make backups.
Usually there isnt much need to factory reset unless you're having an issue with something. What is it you're trying to do?
I wanted to flash a stock based rom. Thank you.
Hi,
So I am new into android and flashing. I performed now happily flashing 10 flashes, using sammobile stocks and custom roms, using odin and philwiz.
I did several hard formats, cleared cache, wiped data through recovery, but I noticed something...
Data is not really deleted.
When I flash for example custom rom, I firstly do factory reset, then clear cache and wipe data, but after flashing custom rom, there are still remaining folders from previous rom
How come, why? How to completely remove this.

You mean folders on your internal storage? You should delete them manually.
Or do you mean that there are still folders left on the /system partition? Then you are not wiping properly. A factory reset = wipe cache, wipe dalvik and wipe data. A full wipe also includes the /system partition.

Wiping with custom recoverys won't delete folders and stuff.
Go to settings -factory reset.
When you want to be sure that really EVERYTHING is deleted you have to burn your device ^^

If you wipe the system partition it will wipe the rom (operating system) from your phone. Like @a602820922 said, the easiest way to wipe everything but the system partition is a factory reset. If something in the system partition has been overwritten then you'll have to reflash your stock rom to undo any changes made.
