after update from rooted? - Galaxy S I9000 General

after I rooted the SGS, if I factory reset the SGS, will this make it unrooted?

It should, because rooting just modifies the system settings/kernel. If you reflash the firmware, it will wipe these files

Factory reset with root

I updated with the RUU and am now rooted ( have soff). If I perform a factory reset, will my phone still be rooted with s off running 2.2?

it should stay rooted and S-off stays as well. su and the su app are put on the system folder so it would not be cleared with a factory reset.
Factory reset formats your DATA so you lose all downloaded apps and data associated with those apps and settings you made on your phone.

if i factory reset my phone, will it remove the root

will the root be gone if i factory reset my mytouch 4g?
Yes. Everything Will be wipe, superuser too.
Wrong. Actually, no. Not at all.
Factory reset wipes the /data partition, which holds user data.
Superuser resides on /system partition, which isn't wiped, and the fresh system after wipe will retain root access. Superuser app might be installed on /data, but the actual SU file will be on /system.
To remove root, you need to unroot - or flash non-rooted stock ROM.
Right, "factory" reset is a bit of a misnomer on Android.
There is no backup of the factory firmware if you have modified your system partition.
But if you flash a full RUU or PD15IMG.zip of the stock ROM, then yes you will lose root. However if you still have Radio S-OFF, you will still be able to flash unsigned images through the bootloader.

What ROM do you have? This all depends on the current ROM you have. If you did not update your ROM, then you will lose root. If you only updated your ROM and did NOT update your recovery, you could ruin your device potentially by selecting that option from within the phone or the stock recovery.
However, if you have a custom (probably rooted already) ROM and you have a recovery like clockworkmod recovery installed, then go ahead and wipe away. You can also clear just your cache, dalvik and many other stuff, the menu has a lot of options.

[Q] Safe to update?

So, I'm on Stock 4.3, with Xposed Framework and franco kernel. My question is, can I flash the factory image for 4.4 directly, or do I need to wipe data/cache? I know I'll lose Xposed since it's not supported for 4.4 yet, so if my first question is not possible, and I have to wipe, I might as well get a custom rom. A second question is, once Xposed is available for 4.4, can I return from custom rom to stock one just by flashing factory image, without wiping data? Thanks!
to flash the factory img, you have to flash it via fastboot. itll wipe out your partitions when you do flash it, so wiping anything is pointless.
So I'll lose all data anyway if I update? Well damn.

[D803] Does doing a factory reset remove root? (applied via IORoot22)

As per thread title, I was wondering if performing a factory reset removes root? I do not yet have a custom recovery, and the local stock KitKat OTA update is going out soon. I was considering holding off on the custom recovery and taking the OTA update, but my understanding is that doing so rooted will cause problems so I'm not about to try.
Basically, just how "reset" is the "factory reset" - and do the factory reset options in the Settings>Backup and Reset do the same thing as the Factory Reset from Power+VolDown boot?
root stays
Um, I'm pretty sure you lose root.
Your phone gets reset to factory default, which is no root...
And yes, it's the same as doing it from stock recovery or from the settings

three questions about Nexus 6P

hi guys,
please i have some questions i really need there answers:
1- (rooted phone) if i do a factory data reset will the root gone and the TWRP also ?
2- (rooted phone) is there a way to install an update if i got it ( like update security patches "monthly" ) on rooted phone without wipe data or loosing the root or TWRP?
3- (rooted phone) if i reinstall the factory image full,the root and TWRP will have gone or not ?
thanks a lot !
1. If you use systemless root a factory reset will remove it. If you use a root method that modifies the system partition a factory reset won't remove root. Factory resets will not remove TWRP.
2. Installing monthly security updates and keeping TWRP, root, and data can be done by manually installing the update using fastboot and doing the following:
-Systemless root method: flash everything EXCEPT the recovery, boot, and userdata images.
-System based root method: install everything EXCEPT the recovery and userdata images. You will have to reflash Superuser/SuperSU (whichever you prefer) in TWRP since flashing the system image will remove root. There's no way around this.
3. If you use fastboot to install everything included in a factory image you will lose root, data, and TWRP.

Could you explain me what are the difference between systemless root method and system based root method, in order to get know what is it the method that I used

If you are running Marshmallow or Nouget and used a version of SuperSU that is a year or less old it does system less root by default.
You can flash OTA updates on a rooted device with FlashFire without using a computer.
You can also flash an OTA image in TWRP and then simply flash root after, before you boot the phone. If the phone boots without root, out will wipe TWRP and leave you with stock recovery.
But honestly, from the questions being asked, you might not want to try this stuff until you understand it better. Losing root and TWRP is not a big deal. You can flash them again in about 1min and 30 seconds, so it's not worth worrying about.

Why would factory reset remove systemless root? I expect factory reset to only reset what you're supposed to have changed since factory image. That is /data.
Systemless must be in /data if it's not in /system, right? I don't really know much about systemless, because I don't use Android pay, Snapchat or play children's games haha.
But my guess is that if it's not touching system, then it must be in data, so wiping data would remove it. But I'm just guessing.

You guessed right. Never thought of that, thought it was actually all done from boot partition.
Quoting Chainfire:
As the binaries should still be updatable, and we don't know the space we have available in the boot image itself, we're mounting a (writable) ext4 image with /su as mount point from /data, and modifying PATH accordingly. Interestingly, for reasons yet unknown to me, if the image is mounted r/o by init, later remounting it r/w causes a bunch of issues. So we're keeping it r/w (for root) for now.
