How to install custom rom on Samsung Vibrant (US T-Mobile)

FIRST of all,
make sure that custom rom that you want to install is compatible in your area (e.g., US)
otherwise, you might not be able to make a phone call on your device due to different country code.


1. Root the device using Superoneclick  http://shortfuse.org/?page_id=2
USB debugging mode  -->  execute Superoneclick  -->  root

2. Install custom rom using Odin3 1.85   http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0CB0QFjAA&url=http%3A%2F%2Fforum.xda-developers.com%2Fattachment.php%3Fs%3D99b3b5d0c89da26121a24a015281ffe3%26attachmentid%3D581913%26d%3D1304094576&ei=ApHETozaJOKssQKjl5G1Cw&usg=AFQjCNGclBBBtaSVwjiLJkCJwrnQis_1Jg&sig2=nbierkHZxjU5gRNa3fBx5A

(1) power off  -->  hold volume UP button  +  plug USB cable in  -->  download mode
(2) run Odin3  -->  load PIT and PDA files for custom rom that you want to install  -->  start
e.g., Simply honey custom rom   http://forum.xda-developers.com/showthread.php?t=1021383

If they provide ZIP file instead of PIT and PDA files,
(1) copy the ZIP file with filename "update.zip" into root directory of internal SD card.
(2) recovery mode -->  reinstall package
or using "Rom manager (from Android market)", reboot in recovery mode  --> install update.zip
or install update.zip using "3e recovery"   http://forum.xda-developers.com/showthread.php?t=833423

(1) download official Vibrant rom  http://forum.xda-developers.com/showthread.php?t=734475&highlight=stock+vibrant+rom
(2) using Odin3, restore
