Question [SOLVED] Can't root! "E: signature verification failed"

My Vibrant used to be rooted. I just updated Tmobile Froyo KA6. I try rooting using Z4root, but it won't do anything. I manually try and getting:

"E: signature verification failed
Installation aborted"

I read this could be the problem on the forum, but I don't know how to fix it:

"Android system recovery <3e>
Samsung Recovery Utils
-for BML-"

ps.don't know if this information of the phone help:
Froyo 2.2
T959UVKA6
Kernel 2.6.32.9




Can't anyone help this rockie?
Thanks

I tired both...neither works. I read something that Froyo's (legitimately.Froyo) folder structure or.something.of that nature has.changed. Not sure though...I'm a bit of a nub in the realm of.development. Can anyone confirm rooting by any.of.the normal conventional methods (z4, 1click, etc.

I got the "E:signature verification failed" message on my Motorola Defy (Android 2.1 Eclair with Motoblur) while rooting in recovery mode. It was using the SuperOneClick method connecting the phone to a Mac. Actually, that version of the software says once installed in your Mac that is for Samsung Galaxy S, but root all models. I followed the instructions here: http://forum.xda-developers.com/showthread.php?t=739304


I have to say that I tried z4root and was useless; so now I see little alternatives...

USB debugging, SD mount and everything is in the way it should... Anyone can help me please?

Edit: I saw in the mentioned thread that many are having similar problems. Someone said that manually copying the update.zip file in the SD card and then doing the whole thing in recovery mode worked. I wasn't that lucky. Now, at the bottom of the phone screen I get the following lines in yellow:

E:Can't open /cache/recovery/command
-- Install from sdcard...
Finding update package...
Opening update package...
Verifying update package...
E:signature verification failed
Installation aborted.

So I am stuck here.

Same thing happened to me when I did the kies update for 2.2 ka6 and hated froyo stock. I tried to root and couldn't. Long story short, I Odin'ed back to 2.1 and used one click root which worked perfectly. Running Bionix V now no problems .
