cannot root - error message - have tried several methods

---

I have searched the forum, and google about this error message, and have found a few other people who have gotten it but no one has responded to them. So if there is a fix out there, I'm sorry, I was not able to find it before posting. Thanks for helping me out!

This is my phone information, out of the box:
Firmware version: 2.1-update 1
Baseband version: I897UCJH7
Kernel version: 2.6.29
jetaek.lee@sep-11 #2
Build number: ECLAIR.UCJH7

I tried the One-Click Root in this thread:
http://forum.xda-developers.com/showthread.php?t=739304.
It gave me the Superuser permissions app (with a android skull-and-crossbones icon). I could open this app, there were no apps listed within it, and I could access the settings, but if I tried to access the log screen it gave me the following message:
"Sorry! The application Superuser Permissions (process com.noshufou.android,su) has stopped unexpectedly. Please try again [Force close]".

I unrooted it with the same One-Click method, and it removed the Superuser App. Then I tried the method listed here: http://forum.xda-developers.com/show....php?t=736491#. this method gave me the Superuser permissions app (with a ninja icon), but this time I can't even open the app. It gives me the same error listed above as soon as I open it.

I then tried to unroot again, using the One-Click method that worked before, but it did not remove the Superuser App.

So where am I now? I'm not exactly sure what has happened to my phone at this point.

have u checked at any time if u had superuser rights??? I've rooted my cappy several times and had not opened once the super user app

download terminal emulator from the market and type "su" (without "") and see if it gets permission...

I downloaded the android terminal emulator, and typed su as directed, and got the same error message as listed in my OP.

Use the one click method again. Download something harmless like drocap2 which us an app that requires root to take screen shots. Open app. If you are rooted the app will ask if you want to grant super user permission.

Excuse me? I thought the whole point of rooting is to get superuser permission. That is, like an administrator in Windows. With superuser permission, you can use apps that are otherwise blocked, such as titanium backup. And you can use custom recoveries to flash other custom roms.

When I rooted my phone, I got superuser app with the skull and cross. Anytime I use an app that requires superuser permission, it will record so in the superuser app.

I think you already had root the first time. Now, I don't know what you have done to stop the phone from being rooted again.

Did the One-Click root again, this time it said it couldn't find the update.zip. I really don't understand what's going on.

Edited to add: When I go to Settings-->Applications-->Manage Applications - Superuser is not listed there. It is on the main applications page, but I cannot open it - it gives that error message.

Tried to do the one-click root again, for the I-don't-know-how-manyieth time. I watched the green dos screen very closely, and it said something about not being able to update root... then it quickly went to the blue screen that said I was rooted and the phone would be rebooted, select reinstall packages, etc.

Hoping the more information I can give will be helpful.

Why don't you test the phone. Go to market and try to get an app that only works if you have root (i.e. with superuser status). I would suggest getting Titanium backup. If you can get it and can get it to work, then you have root.

Edit: Just read your last message. I think you did not do the last step: Get the phone in recovery mode (holding updown volume switch and on switch at the same time). It should lead you to blue screen and then you have to select update.

I did get to the recovery mode. The one click program reboots the phone directly into recovery mode, but I also used the volume and power key method to get it to recovery mode when I tried the manual copy of the update.zip method.

But on recovery move (blue color), did you use vol down to move the highligted line to "reinstall packages" and then use power key to select it? Otherwise, I am at lost as to what you did.
