[Q] Help with a rooted/flashed Galaxy S2 - Samsung Epic 4G Touch

I rooted my Galaxy S2 then rooted Blazers Sexy Can I rom. I did a back up of my stock rom after I rooted it. Now that Sprint/Samsung MAY be releasing stock ICS, I may want to switch over to that. The battery sucks on Blazers rom. Anywho, if I restore to my stock GB backup with root and get the OTA update, am I doing any damage besides losing root? Could my phone be bricked just restoring my backup and updating? Also, if I decide to not do the stock update and keep my root, can I restore back to my stock GB backup then flash a new ICS custom rom with no issues? I keep wondering because I see how if you flash an ICS custom rom, you have to go back to a stock version before you flash another. I am just wondering if my backup is enough.

if you want to go back to stock el29 i would use sfhubs el29 1 click odin, then restore your backup....
if you want the stock system while keeping root just use the ff18 rooted 1 click as opposed to accepting the ota
if you're just upset about battery life but otherwise like the rom you're on now look into kobridge tweaks, and good practices for battery conservation- i.e. sync manually, set brightness low, etc... these could potentially greatly extend you're battery life

Root question with ICS on the horizon

I am running stock 2.36 with EL29. I would like to be able to tether and install an Internet unthrottle tweak I just saw and keep everything else stock. Can someone suggest the best path to achieve this? I have used the phone stock for about 2-3 months. It does about everything I need in its stock form. I miss these two things from my old Palm Pre.
Also, if I root to achieve this will I have to unroot and remove those tweaks to update to ICS?

I am not familiar with this tweak but if its more than just an app then it shouldn't be kept through such an upgrade. If it works with ICS then just redo it. There is often not much harm in trying to upgrade without wiping everything but you can face many problems with the causes of which being unknown just makes it more heartache than its worth.
Since the zerg exploit no longer works your going to be rooting the phone the same way your going to be rooting ICS. ODIN over a rooted tar for EL29. This can be done now in a no data fashion on your stock phone and you wont lose any contacts settings or apps. Once any changes are made to the system, possibly this tweak trying to allow an over there update can be disastrous.
Right now many of us are running leaked ICS roms that were prerooted and flashed via ODIN or custom recovery on EL29 or other gingerbread roms. If you have really messed with the system and even if you havent it would probably be advisable to backup your contacts and data and flash the phone with the intention of wiping everything on it, wether this is ODINing over the data destroying version of the tar or using Calkulin's format all in custom recovery.
With the tweak out of the question rooting your phone now and getting rooted ICS later is as simple as flashing a tar through ODIN. Sfhub has many "One Click" odin's packaged up ready to go in both no data and regular form. Sometimes final builds are leaked before the OTA but at worst you probably wont have to wait more than 48 hours after ICS is released to get the latest stable build from here.

Can I ROM + keep stock loaded?

I want to run leaked ics.
I also want to keep stock GB.
Is this possible?
Advisable?

Back up a nandroid of your gb before you flash ics. Or just use odin one click back to el29.
Your best bet would be to read through these forums and get a real good idea of what your doing so you don't end up with a bricked phone!
You could do a backup of your current GB setup then try an ICS rom out. That way if you dont like it you could just restore back.
Just run whatever you want on ICS, then use sfhub's one-click odin package to safely flash back to GB if you ever need to. Make sure you read up about bricking before flashing ICS.

EL29 rooted to OTA ICS update

Hi. I have rooted EL29 right now and ICS OTA download notification is up on my phone.
I'm guessing I can't just OTA as is.
What is the best way to update? Unroot it to stock EL29 then get OTA then root it afterwards?
I haven't looked at this site since EL29 release so I'm kind of behind about new stuff and forgetting lots of what to do and NOT to do....
I just want well functioned device. I have no intention to try out new ROM or anything.
The reason I rooted was to use tether. That is the only reason.
So what is the best way to go for me?
If you rooted and did nothing but tether you can take the OTA, if you removed system files etc it will fail.
You lose root taking the OTA, No root exploit available. Rooted FF18 is achieved the same way you can get to it from el29 - http://forum.xda-developers.com/showthread.php?t=1721229
No Data is the same effect as the OTA. There are problems with not wiping the phone. Swype data for example needs to be deleted for swype to work. This is one of many things that OTA users needed to do to make their life work normal.
Well I'm no expert but I flashed my phone back and forth between ICS and GB more times in the past week then I want to think about. I went from EL29 rooted stock to the ICS OTA without problems. If you want to flash to a custom ICS I would suggest using Odin to go back to EL29 rooted and then flash from there. For what I read the risk of bricking occurs when performing a factory reset on ICS OTA.
So I'm on CM9 now and here is what I did.
1) one click Odin to EL29 rooted stock.
2) D/L most recent CM9 build and gapps
3) Flash through CWM
4) Enjoy!

Will rooted stock rom with CWM get JB update OTA ok?

If my S3 is stock rom but rooted with cwm recovery loaded, will I be able to get the AT&T OTA JB update once it rolls out with no issues? I understand I might lose root, but is that it? I know it will be a couple more months, just want to be sure the phone will be able to get this with no issues when the time comes.

From what I understand, you need the stock recovery in place for OTA updates, otherwise they will fail. Which makes sense.
Ok that makes since, so closer to go time I can just put the stock recovery.img on there right?? Is it that simple?

flash to stock via Odin, so yes...

Or you could just wait until the update drops and somebody posts a stock rooted version and update it through Odin.
Ok so have to flash the stock rom itself and not just the recovery. I have only really used an older Galaxy S1 to mess with flashing and stuff and never cared about the apps and everything, just would put a rom on there and when needed put it back to stock(borrowed it for a couple months). So if I do a titanium backup of apps+system data I can flash the stock rom, I assume root again and then restore the apps? let it update and Im done, or assuming the stock At&T JB rom is available on XDA I can just flash it on there, root and restore from titanium? Those are the 2 options if I want to stick with stock right?

Right, but it's not usually recommended that you install apps+data with TiBu; better to just install apps only.
-Ryan
Got ya, I do a backup with apps and data to be safe, but you can just restore apps only from that right?

You can. Though could also just let the Play Store redownload your apps for you.

[Q] Restore or flash a new rom?

well i think that maybe it is stupid but anyway.
I was at 4.1.1 stock rom just rooted and I made a backup(just in case) but since I found the SDS topic(I have the chip affected) i updated to 4.1.2. The first days my battery was more or less normal but I was studying and I didn't used it a lot so my believes were wrong, i have a potential draining and I want to flash the 4.1.1 stock rom and put the kernel such as perseus or red pill.
It is better to restore the last backup or flash a stock clean rom via odin?
Thanks!
