Will a factory reset from CWM remove CWM? - Samsung Galaxy S (4G Model)

and if so, is there an easy way to restore it?
note: i edited the title just now

Factory reset just deletes your user data apps.
If you want to remove/replace recovery you need to change a kernel.

What changes does factory reset really make?

What does factory reset in Sense settings actually do and is it the same as Factory reset in the bootloader menu? I'm asking because I was told by HTC support to do a factory reset even when I told them that I have successfully installed two different RUUs. Will the factory reset make any changes that the installation of an RUU doesn't make?
Same here, have a Factory Reset Question...
I'm currently running custom rom Android Revolution hd 3.6.9 - if I want to reformat and reinstall the rom, since I have so many apps already, and I just want to refresh, can I just hit settings / SD & Phone storage / Factory Data Reset?
Or do I need to re flash the same custom rom under recovery?
Or do a factory reset under recovery?
factory reset simply takes the rom at the state where it bootet the 1st time. the rom you have installed that is. so yes you can use it as a frest start, no need to flash it again. it doesnt do any changes that shouldnt be there. just puts the phone on it's initial state where your current rom booted the first time.

Cold Boot/Wipe Data/Factory Reset

Hi,
Can any expert tell me the difference between cold boot/wipe data/factory reset?
I know cold boot clears up the cache and all user data/apps will stay. Root will stay too.
factory reset will erase everything and all user data/apps will be gone. Will root stay?
How about the wipe data in cold boot menu?
Will we lose all user data/apps by choosing wipe data? How about root?
Thanks.

As far as I know Wipe Data in the boot menu and Factory Reset are the same thing. As you say they will delete all user data and apps, leaving only system apps. You will lose root when doing this, but I have read that you can restore with OTA RootKeeper (if you backed it up before doing wipe), since this will be stored in the system part of the drive which doesn't get wiped. So you will need to redownload RootKeeper and restore root. I have not tried this, but from what I have read it seems to be possible.

Scroll down to bottom of page. Good description of cold boot vs reset.

Factory reset will not touch the su binary (/system/bin/su and/or /system/xbin/su), which is what root depends on.
You'll need to reinstall superuser or supersu, but the actual rooting will stick.
Wipe data PROBABLY works exactly the same.
Factory reset is in other words safe for root.

Boot After Factory Reset?

I'm switching ROMs and want to do a factory reset to be safe however my recovery doesn't read the external SD card. If I factory reset, could I get back into android to transfer my file over? I know you can probably adb while at recovery and do it that way but adb always gives me headaches.
EDIT: I was thinking it wipes user data on the internal SD. But I'm pretty sure it doesn't right?
EDIT2: Found the answer. Factory reset via CWM doesn't wipe user data but factory reset via settings does.

[Q] Factory Reset wipes root!?!?!

So i rooted my tablet when i had ISC then i updated to the latest firmwares but the question is if i factory reset my tablet will i lose root again? I did this once but i lost root (super user deleted). So i had to down grade and reroot ics and i just updated again but im wondering if the factory reset is basically losing my root or is there an error to prevent this? I want to factory reset my tablet since everytime i update my tab in order for it to run smoothly like other systems. If anyone has an answer please let me know! Sorry if you dont understand my english -_-
Hell-o Niceguy and welcome!
Try cold booting first in order to save your root.
Factory reset will wipe all and place you back at the factory state.
So yes your root will be gone.
Hope I have understood you correctly.
I've never done it myself, but factory reset should not modify the system partition, so it should not be possible to lose the su binary that gives you root access.
Rationale: The system partition is read-only in normal use, and there is no other partition that contains the unmodified factory image of the system partition.
Flashing a complete Asus firmware however overwrites the complete system partition, which *will* kill your root.
Updating the Superuser or SuperSU apps through the Play Store can place them in the data partition instead of system. They would then be lost after a wipe. You could try reinstalling from the Play Store...

General question on factory reset

Hi
There are 2 ways to factory reset, 1 in settings and 1 in Recovery.
If TWRP and Magisk are installed will both or either one reset to
no-root and stock Recovery?
Thanks
Either will only wipe userdata, that is your installed apps, settings and files. Neither affects any modifications you have made to either system or boot partitions.
