Error message I get when I r un the update.zip is:
E:ERROR in /sdcard/update.zip
It starts to run and looks like its trying to identify the phone , by looking for "I9000" and falls over with the above message
Then I got brave ( or may be follish ) and took the update.zip apart and drilled down and found the string I9000 twice and edited it ti I9000T , the re zipped it and put back on phone.
Now when I run the update.zip it got further but just stopped.
I'm way out of my depth now.
Where can I get the right update.zip to ROOT my phone ?
