My Galaxy S (indian version) is giving me lots of trouble after I installed froyo using Odin. Right now I have baseband version xxjp2 and kernel 18.104.22.168. I want to downgrade my phone to 2.1 or to official firmware but I am not able to do so using kies as it says this version cannot be upgraded. I have no record of my official firmware and find it difficult to pick the right one from samfirmware.
The current versions activity launcher is crashing frequently and the phone has very annoying lag time.
Well without your original Values the best you can do is get the next best thing.

Since you want the Indian Firmware, I believe it would be in the same protcol as Asia so you want to get the newest Eclairs or Froyo,
If you scroll down to Asian Roms,
For Froyo the Latest is I9000ZSJPE, and
For Eclair the Latest is I9000TGYJH1, and
These are official Roms so this is as close to your old Firmware you can get, maybe even same.
ya.. but problem was solved few days ago.....
