Root [Guide] Root for Official 2.3.5 With Guide

I was having some issues (tethering message and short battery life) with the 2.3.5 upgrade via Kies Mini, so this morning I decided to do a factory reset via the system settings. Interestingly, my phone stayed rooted after the reset. I was expecting to lose root and having to re-do the root via your instructions (which I used the first time). Is this normal behavior?

Yes that is normal.

"Factory reset wipes the /data partition, which holds user data.
Superuser resides on /system partition, which isn't wiped, and the fresh system after wipe will retain root access. Superuser app might be installed on /data, but the actual SU file will be on /system.

To remove root, you need to unroot - or flash non-rooted stock ROM."

Basically you lose user data and does a software reset, but not system data. A factory reset is not a repartitioning of the phone as a whole.

Thanks again for these great instructions! I ran through the process yesterday in about 10 minutes.

I backed up all my data, but it was not necessary; I lost nothing.

At the end of the day, I'm glad I have root back and could wipe all the bloatware. I still get the tethering error message when I boot or connect as mass storage, but it just a minor nuisance. Also, no real improvement for GPS, but that was never promised, I was just hoping :)

Again, perfect instructions; thanks again.

so if i backup with titanium then upgrade to GB via Kies, do I have to reroot to restore titanium? Or just upgrade to GB with no backup (sounds like I wont lose contacts, texts, etc), reroot and all is good? sounds too easy am i missing something?

So far no one has reported losing info on the update. I would still backup though! Yes you will lose root and have to reroot 2.3.5 to use Titanium and restore your backup. Were folks are losing user data is factory reset to stop the tether manager error, but it would seem some are using Titanium to get rid of the error.

I dont get it. I cannot connect to a PC. I have read a thousand forums. I have 2.2 and I am rooted. My phone is a mess because I tried to go to GB. I cannot get it to connect to a PC. Is there a way I can install a file on my phone then boot to it. Question will this take me to stock so I can possibly connect to a PC and move forward?

I read about it here, "Here's how you Unroot your captivate"

"The One Click Lag Fix app rooted my phone, but -- and its developer is aware of the problem -- it cannot unroot it (this is Captivate specific). I did a lot of research and couldn't find a good way to do it. I found this Update.zip file that is actually works (it unroots). It worked for me. I'm posting this information and file here because it was a painful process and I couldn't find this information anywhere on the web.

Just follow these steps (Usual disclaimer: I am not responsible for any damages):

1- Copy the attached Update.zip to your \sdcard folder
2- Turn off your phone
3- Turn on your phone, while holding the Up and Down buttons simultaneously on your volume control. This will take you to recovery console
4- Select the option to reinstall packages. This is it it will reboot and unroot your phone.

Note (Dev talk alert): Someone needs to tell the One Click Lag Fix developer that his script for unrooting is missing the SGH-I897 conditional in the assert statement. That's why his Update.Zip does not work on the Captivate. I found out the hard way."

Sorry if this question has an obvious answer...lol

I just updated to 2.3.5 via kies with no issues. This is my first attempt in rooting any phone. Will I lose any data/texts/apps/photos/etc. while rooting?
Thanks!

EDIT: Oh, and at what point can I put my simcard back in?

EDIT #2: I just went ahead a did it! Everything worked great, nothing was lost! Re-entered sim card after final reboot. Thank you very much for the detailed write up for idiots like myself!

So how to get the stock kernel file with mega upload shut down?

Hey,

Thanks for this great info. It seems very easy to do. My one question though, will this only work for AT&T captivates, or could my Canadian Rogers Captivate work also?

Thanks!

Thanks!

1) the first post, I have attached the downloads in .zip.

2)Not sure about Rogers, you may have to find the Rogers stock kernel to flash back to, (not sure the version as I am not on Rogers) over at XDA.

3)You will not lose any info at all, you may have to redo your WiFi settings, but that is about it. It wipes nothing at all when you root. (not saying a backup wouldn't be a good thing, or pulling your pics and contacts at least)

Thanks for this. Easy cheesy! I was rooted on stock 2.2 before. Upgrading and rooting was as simple as it could be. Didn't lose a thing and the whole thing took about 20 minutes, including root. Not sure if I have to install busybox though-Tibu is working, as well as a few other apps that require root. All I have installed is superuser

I installed a custom rom for gingerbread 2.3.5 I897UCKJ2 a few months ago can I root it with the download in this thread even if it's not the official version?

You will just need to track down the proper stock kernel to put back on it. I am not sure how kj2 modem etc will like the kk4 kernel. I am not at a PC to post a link, but look on XDA for a stock kj2 kernel and use it instead of the kk4 I have attached. The instructions will be the same.
