can i flash back to 2.3.5 - AT&T Samsung Galaxy S II Skyrocket SGH-I727

when i bought my phone it came with 2.3.6, since then i have rooted and flashed cwm, my question is can i still flash back to stock 2.3.5 to download the kies ICS, or will this cause a soft brick. also can i just down the ICS stock tar and flash this with odin?

Sticky topics my friend and search but im sure you can odin back to stock or through kies

I was in kdi stock. So i flshed kditar. On odin because i was getting a busy box problem. After that i enter recovery and flshed kg6 odexed.zip
but know i got stock on the boot logo. And icant go into recovery.
I can go into download mode but dont know what to do i dont want to hardbrick my phone. Please help.
Odin the kg4 gingerbread leak. Odin all the files and place them in the correct areas of Odin. Follow the directions and you will be fine. Find it in the dev section or in the bible.

Thank you verry much. It worked perfectly
after odining that leak, you may want the latest version, it won't wipe data.
Download Kj6 AOSP Style and install it.
do you know if we can get root on any of this roms 2.3.5 or 2.3.6?
Absolutely. Odin one of Dr honks gingerbread kernels. They automatically root and have cwm recovery.

Rooting question

Is there any other ways to root my phone besides the "One-Click-Root" I think it takes to long and I want to root my phone fast. Does z4root still work on.this phone or will it just brick my phone?
Sent from my SGH-T959V using xda premium
I think z4 works on froyo.....not gb. Just Odin flash one of honks kernels for root and cwm...see dev section.

Just Odin flash a modem. Like Honks.

Z4root is not going to work. Either use Superoneclick or Odin.

Read relative links on the Bible link at http://forum.xda-developers.com/showthread.php?t=1117554 , especially those relating to using Odin to flash for the first time.
Odin is at http://forum.xda-developers.com/attachment.php?attachmentid=557757&d=1301649433
GB rooted kernels are at http://forum.xda-developers.com/showthread.php?t=1194032, but you need to flash GB bootloaders through Chadsters KG4 at http://forum.xda-developers.com/showthread.php?t=1183413 prior to flashing a GB kernel if you are still on Froyo.
You can also just follow FBis251's guide for getting on GB at http://forum.xda-developers.com/showthread.php?t=1223765
Froyo kernal ( Bali3.3UV ) is at http://forum.xda-developers.com/showthread.php?t=1080871
Download and open Odin, pull battery from sgs4g, connect USB, hold both up/down vol buttons while reinserting battery....phone should be in download mode and show up in ODIN. Follow OP instructions for whatever Rom / Kernel you are flashing for which files to place where....don't change any options in Odin...just put the files in correct location and hit start. If you are on Froyo, then maybe start with Bali3.3 to get acquainted with Odin and the SGS4G
If you are not 100% on the process after reading the guides then I would advise to hold off and post your remaining questions on this thread to get the answers you need to be 100%. The whole process is very straight forward once you have done it a few times, but doing it incorrectly can cause problems.
Oh, and never, ever, ever use Rom Manager.

Odin flash a kernel. flashing a modem doesn't gain root. I'm sure that's what you meant though

Uninstall a rom and go back to stock

I flashed my phone with NexusMod ICS Beta when ICS leaked for this device. Is there anyway I can either revert back to stock 2.3.6 and then update to the official ICS or just update from where I am (4.0.3) to the offical ICS?

I really appreciate the link you sent me. But these instructions are for the opposite of what I am trying to get done. I I want go from flashed rom to stock rom. I used to have stock 2.3.6 and flashed with a custom 4.0.3 ICS rom.

Modem without ROM

My fiancés rocket got updated to the newest firmware, with the ucli3 modem and now experiences issues with connection in certain places.
My question is, can I simply root her phone and flash a new modem over her stock rom? I'm pretty sure I can, I just need to make sure... She'd kill me if I messed up her phone lol.
Thanks

those thread have the things u need to put on a custom recovery
1st post in the 3rd link has different radios for flashing.
Yup you don't even need root. All you need is a CWM ODIN tar file to flash a custom recovery via odin and then you can revert back to the old modem.

Unroot needed for upgrade to latest stockrom?

I have the ATT skyrocket rooted and unlocked when I first got the phone in 2011, and is on 4.04. I remember that the post said that I must unroot if I want to upgrade the rom OTA from ATT. Is there any other way to upgrade to the latest stockrom without unroot? I cannot find the post I originally referenced to root/unlock.

^^ what he said. Just get the .tar file from sammobile.com and flash using Odin. You will lose root after this process.
If you want to update using kies (the update is not ota. You have to use kies. ) then s long as kies detects your phone and you have a stock recovery, you should be OK.
However, I believe that you will loose your apps and data with both the methids.. So just use Odin

Thank you very much. I should be able to re-root after the upgrade, correct? Or the lastest 4.1.2 cannot be rooted yet?
I have problem with Odin before, never got anything done with it. Let me try it this time.

Yes you can root the new jb using the same procedure as before.

If your rooted why not just flash a stock rom with the newest update. That will save you the trouble of dealing with Odin.

Trouble? Odin is as simple as place file in pda and click start. I don't see any trouble there....

I meant it more of an hassle. Plug in Odin then uproot do the update then reroot. Just seems so much easier to flash a stock base rom.

Why would you unroot to do the update via Odin. I believe your logic is flawed here. Although I do agree an install would be expeditious via recovery, your argument is flawed.

Just FYI - I was on rooted stock, and just did the update with Kies without unrooting. Now i'm on JB unrooted as a result.
