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.
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
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.
Cheers!
