Did you have any lagfix installed by any chance? If yes, did you remove it before attempting to upgrade to Froyo?

Want to revert back to official Galaxy S i900 Software, what do I need to do? I'm running the JPH Beta version with Ryanz lagfix. Do I need to undo the lagfix and root before I precede? Will I need to flash the stock version with Odin?
before you do anything, you need to first UNDO the lag fix
go to Ryzaas topic to learn how
once you get that out of the way, you can flash back to stock firmware
but first you need to download the correct firmware you want to use, and the correct pit file, it could be 512 or 513 or 800 something....
Before you downgrade from Froyo, be aware some people apparently had serious issues doing so on JPC.. My recommendation is to stick to Froyo from now on, and upgrade to final Froyo when released

I see. But when final Froyo comes out will I be able to upgrade through Kies? An if yes, will I have to unroot and un-Lagfix my phone?
The reason I upgraded to Beta Froyo is I let Kies upgrade my phone software and it almost bricked my phone. At the time I was running the official software but rooted and with lagfix.
So how do you go back to official then? all i get told by kies is that im at the latest version (XXJPK)
Hi there guys.
I can't remember whether my SGS had the JF3 firmware out of the box or not. And, since both JM7 and JM8 are not cutting it for me, I'd like to revert back to my phone's stock firmware. Is there a way to find out what the firmware "out of the box" used to be?
Thanks in advance.
europe = JM2 latest stock
Thank you for your reply.
So JM2 is basically the latest non-beta firmware version?
Also, should I use the "usual" method to flash JM2 and should I get the files at samfirmware?
Please bear with me as I am very new to this flashing stuff.
samfirmware is fast and easy
or you can do it via Kies but it's a challenge dealing with Kies as most people can tell you

Kies would not update me past JM1. I flashed an old firmware to my phone and as expected Kies prompted me for a firmware update. Only to JM1 though and after JM1 was installed it said my phone was up to date, idk if this is the same for everyone else just letting you know ...
Is it even possible to "downgrade" by using Kies? Cause I can't seem to get it to work, even with all of the registry hacks described in several threads, here on XDA.
Guess I'll have to use Odin after all...

I have encountered the same in the past. Not sure on which productcode JM2's available.
Hi all,
I was wondering where I can get the official JM1 ROM for GT-I9000HKDDBT and how to Flash it onto the I9000?
I want to try the 2.2 ROM but only if I can restore the current JM1 ROM on my phone just in case the 2.2 is not good.
Thanks in advance.

You can actually get (and flash) this via Kies (at least as long as Froyo isn't out officially) by changing everything back to JF3 in your registry.
Hi all,
I am on the current official JPO firmware and latest Kies. I was wondering if there is a way to force Kies to reflash the same firmware back. My GPS was working great when I initially upgraded to JPO but something's happened and now its just crap
Thanks in advance
I have a very dumb question for you guys. Do i have to downgrade to eclair everytime i need to update to the new froyo version? Coz its really confusing like which pit file i need to flash for different type froyo. And what about single files and three files? My phone was doin fine evrytime i upgrade to new froyo without downgrading to eclair. But yesterday after flashing the new i9000dxjpe, my phone just showing sgs i9000 galaxy s. What did i do wrong? For examples do i need to downgrade to jm8 if i want to upgrade my froyo from jpa to jpe? Please guys help me on this. Coz its killing me just to find the ultimate froyo firmware.
Thx God Speed
having same problem too, still no one have answer on it?

No. If you use ODIN it should work without downgrading. At least it does for me.
