Waah, I dunno where you're stuck at. This is what I did when I updated:
1. Start ODIN, selected 'repartition', chose 512 pit file.
2. PDA set to the *PDA*.MD5 file, MODEM set to the *MODEM*.MD5 file and CSC set to the *CSC*.md5 file.
3. Booted phone to Download mode (the android pic on screen)
4. Plugged in the phone, ODIN detects the phone.
5. Clicked START and waited until progress box showed PASS (green box).
I don't remember the phone ever booting up to the Recovery mode during the process.
ok can d. seems like i didnt put in modem and csc file. followed the JG4 instruction on the first page
