How to do a complete factory reset on a rooted s3? - T-Mobile, Samsung Galaxy SIII

Ok do I rooted my s3 yesterday using Mr robinson's method not to trip the flashing counter. I'm on stock with the latest update. Stock recovery also. How can I wipe my phone to the factory state but still keep root? If keeping root is not possible, then how can I do a factory reset? I assume the factory reset option in the phone settings won't work. Thanks guys

Factory Reset only wipes user data (APPS, messages, etc.), not the system, which is where SU is stored so you can factory reset without losing root. HOWEVER, I myself have never tried it via stock recovery or the option within settings (Though I firmly believe this still holds true). That said, the only way I can tell you to do it and be ABSOLUTELY CERTAIN you won't lose root is to 1st install a custom recovery (CWM or TWRP [I prefer TWRP]) and then choose the "Wipe Data/Factory Reset) option from within that recovery.
*EDIT*
After I've ODIN'd a rooted stock ROM (Like the one you did to achieve root without tripping flash counter) I have immediately done a factory reset via stock recovery and never lost root. Sorry, I just remembered. Haha. So all you need to do is go into recovery (With phone turned off, hold down the home key + Volume up + Power) and choose the "Factory Reset" option. All it wipes is /data and /cache and like I said, SU is stored in /system so you won't lose root.

Thanks that helps a lot. anyway, have you tried the factory reset option in the phone settings? I suppose it is the same as the factory reset in recovery mode, isn't it? so just to be sure, after doing like you say, everything is wiped except the S.U app that comes with the rooted Stock Rom ?

Factory reset through settings does not remove root, ever. But you will need to reinstall busybox from the market. No big deal

Factory Reset on rooted A100

My A100 is rooted (not touched the bootloader/installed custom ROM) - when i do a factory reset my understanding is that it will still remain rooted (I used ZeroNull's simple rooting method).
So when it's reset - do I simply re-install the Superser app and then Titanium backup - and then reinstall the backed up apps I want - or is there some step I'm missing here?
Thanks!
Factory reset is just that, goes back to how it was from the factory for the rom. In case of stock, no root. Just redo the root again. Or just check for root after the reset, but I doubt it stays.
Edit: after re root use TiBu to restore whatever you want, as its the same rom restore data too, unless some bug is why you want to reset.

Just did a factory reset. As expected it wiped everything - but I was still left with root access.

Ok good to know, thanks for letting us know. I didn't run stock long enough to do a reset on, but my other phones and tabs lost root.

Note that if you deleted any apks and do a factory reset, they are not restored. I deleted several apks for many of the preinstalled apps, and after I did a factory reset, they were not restored. So a factory reset does not really return the tablet to the state it was from the factory(no root, all system apps installed), rather it wipes all user and app data.
Yeah I should probably have mentioned it doesn't do much, if anything, to /system. Any changes there are likely left alone, which is why root stayed. The last time I did a factory reset was on my evo and it lost root for some reason. Same with my rooted stock nook, before cm7.

[Q] Factory reset / data wipe in CWM, will I lose root?

I'm sure this must of been asked before but I couldnt see an answer in my quick google search. I'm away to give my Note 2 to my mum, I want to wipe all data and give her a clean install with bloatware removed. If I use the factory reset / wipe data option in CWM will I lose root access? Is there an alternate way to wipe data and keep root access / custom recovery?
I have factory reset/wipe data from CWM a lot of time......No u don't loose root access, but doing so u just reset ur current rom.....this is my experience.
Thats what I wanted to hear, thanks.

Use Philz Recovery... it gives u the option of fixing root before rebooting... for a clean install use odin... it is better to wipe everything and install the rom again... or at least factory reset from within the rom (it could cause some issues)...

No, If you factory reset you don't loose root, because factory reset only removes your personal data, apps, settings... but not system apps and root binaries.

[Q] is reset/wipe from recovery the same as reinstalling the factory image?

I have been playing around with the nexus 7 installing apps and adding a different recovery.
I would now like to perform one final wipe of the device, reset it, and then make my pristine backup. I'm currently using Clockworkmod recovery. What is the best way to return the 7 back to stock?
Should I just reset/erase using Clockworkmod recovery? Also, will I need to delete my old Clockworkmod backup if I do not want it anymore?
Any advice would be much appreciated.

reset from recovery only resets the user data and depending on recovery, also the virtual sdcard.
It doesn't touch the /system files. You might have installed tweaks to the system. You might have installed root, changes to the slimport resolution, USB-OTG like stickmount may have made changes to debuggerd. None of these get reset with the reset from recovery.
The factory image blasts a factory image back onto the device, bootloader, recovery, kernel, rom, resets user data, etc.
So in your case if you really want to get back to stock before making a pristine backup, factory image is the better choice.

Thanks, the new image is exactly what I want to do. I'm still a little confused about the relationship between the recovery and the image though. If I flash the image again, will I lose my custom recovery and just return to the stock recovery? Is it just like a computer that the image is going to configure the tablet exactly back to the stock image or will I still have the Clockworkmod recovery? I know I can easily reflash the Clockworkmod recovery so not a big deal.
Thanks again for the help.

Factory image flashes stock
1) bootloader
2) radio (for deb/LTE)
3) recovery
4) boot/kernel
5) system/ROM
6) wipes user data / virtual sdcard
7) wipes cache
So your custom recovery would be replaced with stock recovery.

[Q] cwm recovery and factory reset

I have the latest recovery and rooted firmware installed. I would like to do a factory reset to remove a botched Samba install/uninstall.
Will I be able to install Xposed and rbox mods? Any SU issues?
Any advice would be helpful and appreciated.

Doing a factory reset will only delete your personal data files and will not touch system or recovery. If your botched Samba modified files in the system, doing a factory reset will not restore those files. You will need to re-flash the ROM to restore any modified system files.
You can safely do a factory reset with CWM and/or rbox's pre-rooted ROM installed. If you are using a pre-rooted ROM, then SU and root will survive the factory reset. If you are using a stock ROM, then you will need to re-root and reinstall SU.
@jmerrilljr2
You will also need to disable OTA updates again after any Factory Reset.

So is it better to do a factory reset from within CWM or by going to the FireTV settings menu and doing it from there? What would the difference be?
Perhaps the answer to this question should be a sticky.

I haven't tested it to confirm, but there shouldn't be a difference. Both options should trigger the same thing, which is the deletion of /data and /cache. I would perform the reset from within CWM if you are concerned.
I started from the AFTV menu which booted me into recovery so I guess it doesn't matter where you start. Anyway all went smoothly. The only annoying part is that you can't set SU to grant permission by default. (AFAIK) You get the popup screen every time permission is needed.

Root and factory reset

Hello!
I have rooted my 8.4 wifi and have a custom recovery, and iam wondering what will happen if i do a factory reset. Will i brick it or will i lose root?
As long as you do a normal factory reset that doesn't wipe your system partition you will only lose your data, wipe your caches and maybe what's on your sd card (when you do a factory reset from the samsung's settings menu I believe).
Not sure about root though, but since you have a custom recovery you can flash supersu.zip from Chainfire and have root again afterwards.
Should you wipe your system partition download the stock firmware and flash it through Odin. But you will have to root and install custom recovery again after this.
A factory reset should not brick your device. If you erase the system partition, you will have to reinstall your rom again. As far as rooting goes, you said you had a custom recovery installed, so you should be able to flash a SuperSU.zip to regain root.
