Yes you will no longer have root if you update via kies or ota, when the update is finally officialy released. The only way I know to retain root is Using Mobile odin pro . this has an option called everoot which injects supersu right into the rom. you also can reroot after installing the firmware. as many have done with the leak test firmwares recently released.

No it won't

dr.m0x is right. it won't erase any personal data ... The only thing it does is (as far as i know) install a different kernel and install a different recovery program.
PS And btw it also installs the programs SuperSU and CWM
One question about this: is it true that I can't get ota updates after applying cf root? Instead I have to flash them with odin?

There may be a problem with OTA updates, if they work your device will probably be unrooted though so you just have to root it again

Well if you having this problem with OTA, you can always update via Kies which was working fine for me. I was in XXALF6 and rooted and managed to update to XXBLFB via Kies, but all modification, root and custom kernel gone.
Thanks for the help...

OTA`s will be downloaded but not installed. You could try updating with Kies but you will loose root. Best thing to do is flash the update (new rom) yourself with Odin or better yet with Mobile Odin Pro (you can flash firmware with this app and keep root). For you to decide.

[Q] Official ROM update - info

Hello everybody,
my gt-i9100 will receive (short-run hopefully) the update to jelly bean but i have a couple of questions to avoid trouble.
At this time i have ics 4.0.3 official with root and modified recovery (not CWM). I have some root apps installed as "system app" like Android Lost, xposed framework and xposed tweakbox. I know the update will erase all my data (full update not value pack) but there will be problems installing this update with these root apps pre isntalled?
Thanks to all :cyclops:
It should cause any problems as the rom will erase all user apps and root.
What method are you planning to use to upgrade.
Kies or doing yourself through Odin.
As a precaution you could do a factoery reset before connecting to kies or flashing with odin. That way there will be no problems with stray aps.
i think i will use kies.
so i will not have issues having a custom recovery?
after upadte i must root again the device, right? if yes wich root use?

If I remember correctly, a few months ago there was a small update, it goes well but I had to root again the device, so how should I proceed to upgrade now?

[Q] Flashing international stockrom pre rooted?

Hi,
I have a rooted international s3 with 4.1.1. I would like to update to 4.1.2 with mobile Odin because I don't have e computer. The problem is that when I do this I will loose root and the exynous abuse I used to root doesn't work on 4.1.2 so I am wondering if there is a way to flash the new version and root it at the same time via mobile Odin.
Thanks for reading.
Best regards Reclused

you answered your question yourself, use Mobile Odin Pro and inject root when flashing, should work fine.

Rooting difference from S2 to S3

So my S2 died the other day and I went to buy a i9300. Now I've been searching about S3 rooting and I've found conflicting info on this.
So when I first rooted my old S2 I did it with a temporary CWM that disapeared ofter reboot stayed in stock with stock kernel and kies was able to update my firmwsre without deleting root. I actualy updated from 2.3.5 to ICS via kies without removing root or loosing it after.
I was wondering if the same could be done with the i9300 I want to remain stock for now and don't want to replace stock recovery with CWM. Is there a temporary CWM for S3 so I can push the SU binary to system part without flashing anything over stock?

I did try the search button. The only thing i found was someone talking about the new recovery in S3 only flashing signed packages from samsung or something like that.
Thats why i opened a new thread to see if someone had some new info on it.

CF-AUTO ROOT. Installs only the SuperSU app. Does not install custom recovery. Dunno about updates, though. I think it supports OTA.

Use CF Auto Root from here http://forum.xda-developers.com/showthread.php?t=1957273 Download Odin and the CF auto root for your phone all instructions are on this thread
You can still update via Kies as long as everything is kept stock even though its rooted but you wont get any OTA updates that wont work

Thanks. So that method everything stays stock including recovery and o xan still use kies. Will a kies update erase root or will it be like with the s2 where the root sticks after the update?

Yes the update will remove root but after update simply flash root with odin again, only takes a few minutes

Thanks. Going to try it. By the way staying in stock means no init.d scripts right?
