Root root troubles

[mohsen zubaidy]

hello..
I have tried to root my Samsung Vibrant several times....but it keeps saying signature verification failed..installation aborted..what,s the problem with this...??
it,s important to me to have my phone rooted , I have downloaded THE DOCTORZ ROM .. because it supports Arabic..but if there any other methods to install Arabic language without need to root the device ..I,d be very appreciated..
THANK YOU..

Flash Odin back to 2.1 then root. There is sign verification error with 2.2. Details under noob section.
