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.

What was the order you uninstalled the lag fix and unrooted? Did you "Undo OneClickLagFix V1+" then go into recovery mode and install the file you provided?
I think I undid the lag fix then the file system. Either way, unrooting has to be the very last thing you do. The other stuff wouldn't work if you're not rooted.

Successfully unrooted. Did you find that udate.zip at XDA?
I found it included with a Samsung Vibrant rooting tool. I compared it to the one that comes with the one click lag fix (I know a little bit of Linux scripting) and noticed the Captivate model number was missing from the list that checks to see if the Captivate is a supported phone!
It's the same code otherwise, so I renamed the file that came with the Vibrant tool and tried it and it worked.
Thank you for posting this. I have added it to the sticky. Also since this is spicific to Rooting, let me move it to the root section.

whats up guys n gals. i did this procedure and it seems that i am now unrooted. is there any way i can for sure confirm that i am unrooted? i stated in another thread that i had problems communicating with the att server when i try to do a software update (i know 2.2 isnt available, but i just tried it anway). before i was rooted i did the software update and the message it gave me said that there were no updates available. after i was rooted i did the software update and now it says unable to communicate with att server. i just tried the software update right now after doing the procedure up above and it still gives me the error message.
I am a total noob to the whole rooting thing, but would like to unroot my captivate. Currently, I am rooted and running a custom ROM. If I use this file to unroot, is there anything I need to do beforehand in order to prep the phone? (ie go back to stock ROM, or anything like that?)
The first thing you need to do is install ryans lag app, which you have already done. Then go into the application and choose the option "Unroot". This will unroot your phone and restart it. Then check your updates for the ATT OTA update for the GPS fix, download it and it will install. After you install the ATT update, go back into lag app and root your phone by selecting "root phone" or whatever it says. FOR ME the last step did not work. I had to go back and manually root the phone again, but since you already have the update.zip installed you just have to turn your phone off, turn it on into the boot menu and reinstall packages like you did the first time you rooted your phone.. done!
Hi, new to this forum. I have a captivate. I am good with computers but new to smartphones. I rooted the phone successfully using a one click root program from xda. Only to delete ATT bloatware, kind of an OCD impulse. There is also an unroot option. I unrooted successfully but still can not install the latest gps update. I copied this update file to the internal sd. Ran the one click unroot, the volume button option does not work with my phone. Still have an update fail. What do I need to do.
Same here I can't communicate with the update either. But according to threads at android central the oclf should unroot with no problems. Says you first need to remove the file then the lag fix and then unroot.
Have not tried yet cause I'm ok with the phone right now. When the official froyo comes out I will unroot.

I unrooted my phone (deleted the Superuser.apk) and pretty much anything else I could find. I even used the Odin3 1-click to revert my phone back to stock and still couldn't get the OTA update to work. After running Odin I installed Kies-mini and updated the firmware that way. Works great now. Hope that helps.

What up Chromag
Can you post step by step to unroot samsung captivate.
Thank You
Start Kies mini and then plug your phone in and it'll download the JH7 update (the current OTA one). After this I did the "Unleash the Beast" 1-click root and AT&T bloat remover:

Doesn't One-Click-Lag fix have an unroot option? Mine does ./.. haven't tested this yet though.
It does. I think there's a recent thread floating around that makes it sound like the unroot option doesn't work properly for the Captivate though. I haven't tried it though. I'm betting it doesn't unroot enough to allow for the OTA update though.
The more you hack up and mess with your phone, the less-likely that any updates will apply.
This is the inherent responsibility you take on once you start doing stuff like rooting, replacing ROMs, lagfixes, uninstalling stock AT&T apps, etc. There are tons of people who got themselves into your exact situation who never found a solution. Don't assume there is one.
Unfortunately, those who push people to perform these hacks rarely fully-inform their victims of the risks and ramifications.
Even with root, there are several methods and most don't "unroot" properly/cleanly/successfully.

Well in this case there is one - at least it worked for me after applying Odin. I still had to use Kies-mini to update the firmware because OTA wouldn't work though.

Indeed they don't. I tried so many different things to get my phone to update OTA and even an Odin flash didn't do it.
I updated my captivate with the unofficial Froyo update and rooted. Will any of these unroot processes still work for me or should I do something different? I want to make sure Im able to get the official Froyo update when its available and dont think I can while rooted because my OTA update check doesnt work.

I think you'll have to revert to stock using Odin:
I am finding rooting my phone is almost not worth it because I have no idea how to do it. I have read, looked, downloaded, installed, moved, unzipped, restarted, rebooted, re loaded, redownloaded---get the idea? Nothing has allowed me to root my phone. Oh yeah, I did find out that android Market will not allow me to run aps out side of the market place...how do we fix this? I mean really, rooting a phone apparently is the easiest trick in the book and this user feel like failure everytime. Need some help. simple. thats all I need.

As I told you in response to your other post, get the One Click Lag Fix, it's on the market - and just use it to root the phone. See the CapFAQ (linked in my signature below) for more information. Couldn't be any simpler. I was a two week owner of my first Android phone (this Captivate) and even a dummy like me could do it
ETA Ryan has updated and come out with z4root - couldn't be simpler! Remember to donate to this great developer, he's coming up with better and better programs all the time!

I have some type of hardware issue that is causing my Samsung Captivate to charge, but not recognize the data connection. I have tried several cables and none work. Funny thing is, I even had the USB debugging icons show up when there was nothing plugged into my phone.
Well, I need to unroot but the "One-click" unroot app doesnt see my phone ever so it cant push the update. So, I tried going to this thread on my phone and downloading the update.zip file, I used Astro File manager to move it to the SD/sdcard folder and then put my phone in recovery mode to "reinstall packages" I thought it might work, but for some reason it says
--Install from sdcard...
Finding update package...
Opening update package...
E:cant open /sdcard/update.zip
(no such file or directory)
Installation aborted.
can anyone help?? thanks so much
EDIT: ok, Im leaving this up cuz now I know you can Unroot without plugging in your phone!
I had it in Sdcard/sd
it just needs to go in SDcard,
get on your computer, download the update in the first post, email it to yourself, save it to sdcard/
then put your phone in recovery by holding the up and down volume and power buttons.
then you reinstall the packages! Bam! unrooted!
I can now take my phone into At&t to get a new one!

Another nice way to do it is to install dropbox on your pc and put the app in your phone, launch the app, download the file and done, easily found in your dropbox folder.
My SGH-I897 doesn't come up to the recovery console when I press down the volume up/down rocker switch and turn the phone on. It just ignores me. Since it IS a rocker switch, I press it squarely in the middle and make sure that both sides are actually pressed down.
The Unzip file worked perfectly and i am glad i found it.
Thank you..
A rooted phones works good but what is the idea anyway.
question in my keyboards i used to have the n with the little line on top to make words in spanish now it disappear and would like to know if there is a way to fix it.
my phone just tells me authentication failed... it won't work.. help!!!
mine doesnt work either
mine says "E:signature verification failed
Installation aborted" after i chose reinstall packages
my usb is not being recognized on my computer (and i tried it on 3 different ones and none of them work either)... i have to unroot it to have it covered by warranty
anyone have any better ideas?

I take it you're not a big fan of rooting. Now you got me worried.

Gawd, this is exactly why I am worried to Root.
The only reason I want to root is to lower the priority of all my apps that keep on waking up and everytime they do, they kill my battery life. No task killer will fix this.
