[Q] Problems with root [Answered!]

---

edit: I never did figure out how to backup the original rom. As far as rooting it goes make sure that your phone is in download mode and that you are using a real PC. I am using parallels on a mac and I still have yet to figure out how to get my phone connect to the VM in download mode.

Ok so I just got my galaxy S and I have spent a day and a half searching for the answer to this so if I missed it I am sorry.

I can mount the SD card, copy the update.zip (I have tried all of them I could find), reboot into recovery, flash the update.zip, and reboot

When the phone boots back up the superuser.apk is installed, busybox is in the /system/xbin folder but no "su" in the xbin folder.

My phone is an i9000 8GB
Firmware Version 2.1-update1
Baseband version I9000BGJF1
Build Number ECLAIR.BGJF4

I really want to backup the whole system before I flash a new rom.... any ideas on what could be going wrong?
