    Everything seemed to work as planned but when I open Superuser permissions all I see is a blank black screen. Tried uninstalling and installing update.zip again and same thing happens....suggestions?

    okay guys I'm confused. My Captivate is updated to stock 2.2. I tried the update.zip and I get the signature verification failed error. Is there an updated update.zip? I tried the toolbox but could not find the 3.0 download, only the 2.5 download which does the same thing.

    Thanks for the help.

    Thanks for the thread suggestion. I was not able to utilze his procedure but in the thread he sent another person with the same issue to superoneclick which did root the phone. I verified it by loading Titanium Backup which installed correctly.

    But then when I installed ROM managoer and tried to load CWO recovery it said it installed correctly but when I booted into recovery it still came up the the Samsung blue texted recovery. I was hoping rooting would bix these types of issues.

    Are you still able to get back to your phone unrooted? As in, unpower it, and boot it back up into Android OS? If so, i would highly recommend using Super One Click. Used it on my phone, never had an issue. E-signature verification issue seems to be a CWM issue: [Q] E:signature verification failed ClockWorkMod - xda-developers

    Whats the reason for doing the rooting in the first place?

    Method did not work on Samsung Captivate with AT&T version of Froyo.

    It says e-signature verification failed, update aborted. Apparently this zip file is incompatible with the Samsung Captivate or the Froyo version that AT&T released.

    it is compatible, bc tons of other people have done it. but i had the exact same problem when i first got my Cappy, and was trying to root. go here--> [RECOVERY] 3e Recovery Modded w/ No Verification - xda-developers and download the file, and follow the directions listed. it is to install a modded 3e recovery that skips the verification check.

    The instructions tell me to:

    mount -o rw,remount /dev/block/stl9 /system
    That gives me a response of
    mount: Operation not permitted

    Does mounting the system directory read-write require root access? I would expect that it does.

    Yes, it does.

    That's what I thought.

    The whole point of this is that I want have a Captivate running the Froyo upgrade from Samsung. It is not rooted.

    To root the phone I have to have an update that will pass verification. Bypassing verification is possible, but apparently only if you have already rooted the phone. Or maybe there's some trick to bypass such restrictions.

    So can anybody recommend a method that will root a Samsung Captivate phone running upgraded Froyo?

    We need a step by step guide of how to root the 2.2. And I do mean step by step...where files are located is always good to know. Copy to internal memory is vague- many do not know where to find internal memory. Hope someone does a write up. :)

    I know this post is dated but it concerned me and I thought it would help for anyone who decided to root with the Froyo updated (Stock 2.2) on their Captivate.

    I myself had this error:
    -- Install from sdcard...
    Finding update package...
    Opening update package...
    Verifying update package...
    E: signature verification failed
    Installation aborted.

    So delved into page 7 of this thread. Specifically this link that was quoted above for [RECOVERY] 3e Recovery Modded w/ No Verification - xda-developers. Then went to the link that the guy took it from, user untermensch and followed his instructions. Here ->recovery 3e modified to work like recovery 2e - Updated 01/23/2011
    I looked into the archived folder and simply opened the install Batch file and it opens up a terminal. I have screen shots down below.
    It's simple, follow the instructions. Make sure your phone is on USB Debugging and such and while your phone is connected to your computer, follow the on screen commands on the terminal and it will install the 3e Recovery Mod on your phone.
    NOTE: The update untermensch has attached on his post is not for the Samsung Captivates/SGH-I-987. So use the ones available here in the Captivate Forums, like Captivate Root.

    Screen Shots:
    Just opened it
    3e recovery installer.PNG
    It ran.

    Like it says, it automatically reboots. Then after that just follow the instructions like normal provided by others, again, I used Captivate Root.
