How to update firmware (still on eclair) to latest firmware

Hey Shaun. Sorry for late reply.

Basic guide to flashing 2.3.3 OR 2.3.4:

1. Make certain you can get your phone into DOWNLOAD mode by switching the phone off, hold vol down + home + power buttons at the same time for roughly 3 seconds until you get the download mode screen which is a black screen with a yellow triangle and a little android shovelling or something. And also battery should be charged. Most people ask for fully charged, this is so the battery can be reset and optimised to run with the ROM.

2. Once you've accomplished this, fire up Odin (download if you don't have it already but some zip files have it with them) and insert PIT into PIT, PDA into PDA, CSC into CSC and PHONE or MODEM into PHONE.

3. Make sure RE-PARTITION is ticked and connect the phone using Samsung cable.

4. Once you've followed these steps, you should have:
    a. phone in download mode & connected
    b. PIT, PDA, CSC & PHONE boxes occupied
    c. re-partition box ticked
    d. and "ADDED" in the first box by "ID:COM"

5. Click START and let Odin take care of the rest.

6. Once Odin has finished flashing, the phone will reboot. I suggest removing the cable.

If you successdfully completed this sequence, you should now be on Gingerbread 2.3.3 OR 2.3.4 (4 being newer and better). You can confirm this by: SETTINGS > ABOUT PHONE > down to the bottom and it should read 2.3.3 JVP OR 2.3.4 JVQ.

And that's it. A little notice to yourselves and other that read this... Samsung have released 2.3.5 JVR and JVS but I'm not sure whether it's official or not.

Hope this helps!
