Root Here's how you UNROOT your Captivate

[SGS2]

10/10/2011

method: odin 3 one click download. (i thought this was an app, but it is not an app).

long story, but accidentially deleted my stock "contacts.apk" app. needed to unroot. complete 20 hour nightmare over several days, ruined my weekend. i did not want a free contacts emulator, just my preference, and i have read every single comment on this blog, and researched google, and looked at 30 different web sites and pages to do this.

THE UNROOT SOLUTION, FOR ME, A SAMSUNG CAPTIVATE 2.2 FROYO, WAS THIS YOUTUBE VIDEO, LINKED BELOW. i wanted to put the bloat back on the captivate. this method will take you to 2.1. you will then need to do the official "samsung kies mini update" via your mini usb cable and computer to get back to 2.2 froyo and in the future, 2.3 gingerbread, when 2.3 is released, unless the person who made this video updates it. also, there may be better videos, but i liked this video, and this is again, in my opinion.

what the video did for me was to unroot, put my captivate back to stock condition, with all the crap-apps and bloatware. my captivate is a year old, and was 2.1.. if you bought your captivate with 2.2 froyo on it, this method will likely pout you back to 2.1, then you will need to do the official samsung kies mini update for 2.2, or possibly 2.3 gingerbread in the future.

there are many ways to do this, and many opinions, and a lot ofg people here are experts. i am not an expert, nor do i want to be. i just want to do what is as simple and easy as possible. i tried to download zip files, etc., etc. do what you want, it is no difference to me. i am merely and only sharing what worked for me, and what i found simple.

it is obviously not a high tech or sexy video, but it was simple and easy.

good luck..

official samsung kies update for the latest buildware, which is froyo 2.2. this is a samsung site. in the future, i do NOT know if this will or will not update to 2.3 gingerbread. as of this post, it updates to froyo 2.2: http://www.samsung.com/us/support/SupportOwnersFAQPopup.do?faq_id=FAQ00032810&fm_seq=32978

After I Reinstall Packages, I get:
"E:signature verification failed"
"Installation aborted"

Same problem. T__T

Anyone figure out how to fix this? I'd really like to unroot my phone without reverting to factory state. I'm running 2.3.3.

The Superuser app should not be in your app drawer and you can test it by opening an app that requires root such as Titanium Backup and if it says that you don't have root access then you are unrooted.

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."

I rooted mySGH-I897 in the hope of being able to bypass AT&Ts hateful policy of not permitting non-market apps. Unfortunately, I should have updated from 2.1 before rooting.

Will this file and proceedurd work for me.

Thanks in advance,
