[Q] Samsung GS2- Should i update my firmware through Kies after rooting? - Galaxy S II Q&A, Help & Troubleshooting

Hello, just to preface this- im not very technical, but i can follow instructions well.
Anyway, You guys were great to help me two months ago in rooting my phone. I ended up doing it through Odin and all went great. Got all the **** off my phone which was the main aim. I didn't put any custom roms on there as im a bit useless when it comes to this stuff and i felt i'd be pushing my luck after the rooting went so well.
Yesterday i used Kies and it asked me to upgrade the firmware as there was a new version available.
1. What should i do? Will upgrading through Kies reverse the rooting procedure or break my phone?
2. Should i get the newer update from this site? If so- is there any tutorial for updating the firmware after already rooting the phone through odin (chainfires method i think it was?
Thank you in advance for any advice all.
My phone details are ;
ANdroid 2.3.3
Baseband version I9100XXKE7
Kernel version; 2.6.35.7-I9100XWKF3-CL276555
[email protected] #2
Build number; GINGERBREAD.XWKF3

I have used kies to update firm ware after rooting and it did not UN root my phone so you should be fine. It did however install more useless apps that I had to remove.

i would update via kies then go to chainfires post and pick root and cwm to match your new firmwares kernel .
That way you wont have to learn how to flash stock firmwares etc .,

What JJ said is to flash via Kies and then flash the CF-Root kernel from Chainfire to get root and CWM in the phone.

Hi Azeurius,
the thing is that i already have root and cwm on the phone. Ive already rooted.
So im at the point where i can upgrade the firmware through kies, but im looking for advice what i should do overall- nearing in mind the fact ive already rooted, and phone details are in Openingpost.
THanks!

Ok well I am also new here but from everything I have read my understanding is that you have rooted your device and loaded the original Kernel for your current firmware. If you upgrade through Kies then you will obviously have an upgraded firmware with the old kernel (from your 1st rooting).
So when you upgrade your firmware you just have to also upgrade your Kernel through odin so your phone will still be properly rooted.
I stand to be corrected. I only started reading about rooting today as I just got my Galaxy s2 having come from a Blackberry so new to Android but loving it!!! Best os ever!
I think I will root my phone but not going to touch the firmware as ICS should be release on Kies soon cant wait

Any stock upgrade removes root .

Correct
One big problem with Kies is that if you change firmware its possible that you lose the Kies upgrade path as phone codes no longer match .

Hello guys. Im relatively new to XDA. So I might sound stupid. My question is, as jje mentioned above "One big problem with Kies is that if you change firmware its possible that you lose the Kies upgrade path as phone codes no longer match" am i correct in saying that if I update my Galaxy s II (rooted + cwm recovery no custom rom) via kies, then I could run into problems? Also one more question. If I do update via kies, will it remove root and cwm recovery?? Thanks guys. .

Use Odin
I think KIES forbides to upgrade on rooted firmware. Even if it allows you i think you will use your root. I suggest you if you want the latest stock rooted firmware use Odin find the stock rooted XWLSD(Nordic countries) and flash via Odin (Don't use XWLS8 it has bugs), XWLSD is super stable or XXMS1(Poland) or XWLSE(Russia) if you are not from this countries then use XWLSD. If you want custom rom with no mods and no bloatwares use Neat rom or Wanam lite rom, if you want custom rom with mods and no bloatwares use disaster, biftor, omega, alliance rom and etc.

Yeah. I dont mind losing root access. As log as I can get official ota. Btw has the exynos bug been addressed?

It allowed updating firmware on my rooted S5, but I did lose root when it was all done.

Thanks. I will be try updating my rooted i9500 and P600 via Kies. I am not sure if there is already an update for my region available for the S4 but I was prompted to update my P600 only to get a notification telling me that my device has been modified. This was for OTA updating. I really hope it works because I am really not looking forward to un-rooting these devices just for the updates since downloading the stock ROM takes forever. Will post results after trying just in case anyone is interested.
