I'm a noob when it comes to this stuff, so please forgive me if my questions come across as stupid or have been asked before.
My T-Mo GSII is carrier unlocked and has also been rooted. The only reason I rooted the phone was to delete some of the bloatware that T-Mobile installed on the device. I don't understand their mentality when it comes to making you keep applications you don't want, but that's a totally separate discussion for another day.
Anyway, I'm still running the stock Gingerbroad ROM sans the bloatware apps. I have Clockworkmod installed along with their touch recovery manager. My question consists of the following:
1. Can my phone be updated to ICS via Kies or OTA (I assume in a few weeks) in its current state, or must I revert back to the factory ROM and recovery manager?
2. If I can update to ICS in its current form, can I reenable super user? Will I also have to carrier-unlock my phone again to accept international GSM cards?
3. If I must revert to the original ROM, has someone already devised a way to root the phone again? If so, I'd be grateful if someone could post a link to the how-to.
I am pretty sure that you need to be in the stock rom to upgrade.
Planty of posts on google and XDA i believe to go back to stock.
Well FWIW, I've read a few sites that state that if the phone is rooted, Kies will say that this phone isn't compatible with the update. My installation of Kies shows no such error and happily asks if I want to update my phone's firmware. I am hesitant to click the accept button though until I know exactly what's going to happen with phone.
Just to be safe I flashed the stock 2.3.6 on mine and updated through Kies.
After that I flashed recovery and rooted again
Ahh, so if I understand your post correctly, the current versions of CWM will work with ICS?
Yes, but there is a new root.zip file.

Thank you very much indian9990; that was a very informative thread link you posted. Much appreciated!
Anytime! Now just got to wait for Devlopers to mess with ROMs haha
BTW, when reverting back to a stock ROM, do I need to do anything other than flash the phone with a factory T-Mo ROM with ODIN? I assume that flashing to a stock ROM will also remove CWM?
You might even be able to just ODIN ICS lol.
Well the people over at XDA have got a version which you can flash via ODIN.
Step 1: Download Odin. Found here.
Step 2: Download ICS (Don't worry this is just regular stock)
Step 3: Exact the ICS zip that you downloaded.
Step 4: Open Odin
Does it 0:[COMX] <-- The x referes to a # for the port that the phone is connected too.
Click the PDA button and nagivate to the extracted tar file.
Note this should all be down when your phone is in download mode..aka..Odin Mode
Leave all the defaults checked..so..
Re-partion = Unchecked
Auto Reboot = CHECKED
F. Reset Tiem = CHECKED
Flash lock = unchecked
Phone EFS Clear = unchecked
Phone Bootloader Update = unchecked.
Interesting. I may have to try that although I wonder if anyone else has successfully upgraded to ICS via ODIN while rooted. I assume though that the process of re-rooting the phone will have to be done again even with your method described above?
Yea I think so. But if you think about it..
My phones was rooted. I used ODIN to return back to stock 2.3.6 so I don't see why this wouldn't work to bring you back to stock ICS.
My phone was rooted, and it updated to ICS just fine. Of course, the root access was then gone and all the bloatware was back.
Took me a little while to get the root back since a newer version of the su app was needed. Then I deleted all the bloat, and everything is working fine.
Thanks JGB for your response. I assume you simply did the update via Kies?
Curious - but will the upgrade remove any sort of carrier unlocks; i.e. the ability to use international sim cards? I travel quite frequently for work and I tend to purchase disposable SIMS in whatever country I happen to find myself in.
I am pretty sure one's the phone's unlocked it doesn't re-lock it self but i'm not positive. That's an good question. If you find the answer for sure let me know. You can always try putting like an AT&T sim card in there after the update and see what it tells ya
