I assumed you were rooted. Yes you need to root to flash. Go to Nexus S general and sticky for root guides. Easy stuff once you read up and have a go.

I went back to GB, 2.3.6, used this as a guide: http://forum.xda-developers.com/showthread.php?t=1785672
You also have to install FOTAkill.apk before the phone connects to the network, to prevent the phone from downloading and nag you to install ICS and JB.
The end result of going back to GB, is a fast, no frills phone with very good battery life.

I don't see why you have to downgrade it back to 4.0 since jellybean is better in every way.

Hello everyone, im new to android. Ive jailbroken all my iphones but cant seem to find a way of just rooting. Im on official ota 4.1.1 ive found tons of instructions on rooting and custom roms but it seems that I need to install/flach a custom rom. I just want to root snd use my stock firmware. Is this possible? If so, how? Thanks
Sent from my SCH-I535 using xda app-developers app
Use this guide and flash the no-wipe version: http://forum.xda-developers.com/showthread.php?t=1984436. It is this file:http://www.androidfilehost.com/?fid=9390214368362234350. This will flash a pre-rooted version of the JB OTA and keep all your settings, data and apps untouched. You can stay just stock rooted at that point, or you can proceed to unlock the bootloader and install a custom recovery if you want to. Or you can use this guide: http://forum.xda-developers.com/showthread.php?t=2046439. It is a little more involved and can be more prone to errors for newer users.
Thank you, thats what im looking for.

How do I do the above options with a jelly bean baseband? I used Casual at first, when my phone was ICS and just had to get a new S3 with the diff baseband. I can't figure this out. Help please. Thank you!
For now you need access to a Windows machine and use Odin to root jelly bean. There is a thread in the development section. Make sure to wait till you see pass in all the steps before restarting especially when flashing recovery.
Sent from my SCH-I535 using xda app-developers app
No problem. Used to using Odin...I used it on my Fassy. Just wasn't sure if there was another method, because Casual was pretty cool :good:
Hi guys. I need the 4.1.1 stock that I can flash on my phone so I can see if my UI lag is just a problem with 4.1.2. And also I need to know how I can do this. I have a nandroid but I don't know if my custom recovery or bootloader works with it.

Per your nandroid question, you aren't making sense. You can't do a nandroid if you don't have a custom recovery. The status of your bootloader is moot, it works fine either way since its stock, rooted firmware. Your bootloader status matters when you want to flash custom kernels or roms.
Were you looking for the bloated stock tar for Odin which removes root? Both VRBLK3 4.1.1 and 4.1.2 tars can be found in the guide by Open1your1eyes0 thread which is in the dev section. Search and you'll see it.
If you want the VRBLK3 4.1.1 rooted flashable zip for CWM/TWRP then do a search for this in the dev section cuz its fairly old. Flash it in recovery like you would any rom.

Yeah I didn't really word that to well. I needed the 4.1.1 update because I wanted to update to 4.1.2 through Keis because it is supposed to fix lag problems with S3's that came with 4.1.2 stock. I was worried that if I were to do this, it might not be compatible with my recovery. Sorry for the confusion.

Ahh ok, well I answered you in the General sticky as well. Odin flash VRBLK3 4.1.1 or VRBMB1 4.1.2 then you can take OTAs. Any time you flash a stock tar, this removes every trace of custom software except your flash counter in different download mode.

Hi. I thank you in advance for pointers and direction. I have searched around, but want to make sure I am doing the right thing.
I have an Infuse and it is unlocked. It is running with a T-Mobile SIM card.
I downloaded Odin 3 v1.7. I successfully flashed from 2.2.1 (Froyo) to 2.3.6 Gingerbread by using this ROM/Root that I found on another thread here:
************ OPTION C *************
I997UCLB3-CWM-root-deodex-extras.rar
Features in this version
- Entropy's Daily Driver kernel
- Red CWM recovery
- Rooted
- Deodexed
- Zipaligned
- Busybox
- AT&T and other bloatware removed
- Scrolling wallpaper fix
- CRT off animation
- 8 lock screens
- Extended power menu
- Accurate battery mod
The phone is working properly on the new firmware.
I would like to jump up one more firmware to Ice Cream Sandwich or Jelly Bean. Every method I can find seems to include root, and I am already rooted. That happened when I ran "option C" from above.
What is my next step? Can I simply flash a Gingerbread ROM through Odin (after, of course, putting the Infuse in "download" mode)?
You need to flash a (ics) rom from the CWM RECOVERY of the phone not using odin and then you can flash a jellybean 4.xx rom.

Cool. Thank you! I am not sure how to do either of those things. At least now I have some research to do.

My wife finally allowed me to upgrade her phone.. So I've recently just tried out these steps it's amazing to me that jelly bean 4.2.2 cm10.1 runs better than stock gingerbread. Only down side is no mhl.

Ok, I did a little research and I am more clear on the process - (download rom, put it on sd card, flash it using Clockword Mod while in recovery mode). I do have a question. Does it matter what version of CWM that is on my phone?

When I flashed cwm it was red recovery, which is what you stated you had in the first post by choosing option c
You'll have to flash ICS before flashing jelly Bean when you flash ICS it'll change the cwm to a more current one.

one last check ...
Let me check one last time before I do something stupid:
I have a rooted and unlocked (T-mobile service) Infuse. I had stock Froyo 2.2.1. I used Option C from a thread here that rooted it and gave me RED recovery. I used Odin and flashed the "extras" package.
I currently have build #: Gingerbread.UCLB3, kernal version: 2.6.25.7-I997ruxkg3-cl366622, firmware 2.3.6.
I would like to experiment with flashing up to ICS, maybe Jelly Bean.
My understanding is that I can simply drop a ICS rom onto my SD card and flash it from red recovery. Then I do do the same process to move to Jelly Bean.
Am I correct? Am I missing anything? Thank you ALL soooo much for guidance. I am learning and will pass it on!

Its really hard to screw things with this phone specialy.....
Yeah.....its typed on Note 3.
Ok, I followed the directions provided and flashed Infinitum ICS. All works well with the rom. Recovery is distorted. I see directions which include Heimdall to correct the recovery.
Does that process just correct the recovery or does it revert me back to something other than Infinitum Rom? if so, can I repeat the process to get the rom back?
My next step will them be to move to jelly bean and be happily ever after.

When you update your phone you don't flash the gingerbread bootloaders right, you only need to flash the gingerbread bootloaders and that will fix the problem.
Sent from my SGH-I997 using XDA Premium 4 mobile app
Ok, I blew it. Flashed back to Gingerbread.UCLB3, firmware 2.3.6 with Heimdall. Recovery is still totally distorted/unreadable.
Next move? I assume I should flash a Gingerbread bootloader. Where would I find the right one? I don't want to screw this up. Then I can move to ICS and then JB with no issues, right?
I 100% appreciate your help and I SWEAR I will pass along what I am learning to a newbie as soon as I get a chance!

Hey! It looks like I corrected the issue before you messaged back. I ran Heimdall again. Thought I had blown it. Screen went all speckled red yellow and blue on me. It was kinda pretty. I booted in download mode and it was speckled, too. I followed the steps to download mode even thought I could not see the screen. I flashed through Heimdall again, it ran properly, and then booted into download mode and ran with "bootloaders" checked. It seems all is well. Recovery mode is working (no distortion) and is blue (Android system recovery 3e).
Can I follow the steps I took to go to ICS and then JB (if I decide to go to JB) now with no other issues?
Dude, I really appreciate your guidance.
