Root Didn't disable lagfix before install. What do I do?

[klims]

Hi Guys,

I got a little too excited when I downloaded a new ROM and tried to flash before I had removed the lagfix. Initially the ROM installed fine but when I tried to apply the lagfix to the new ROM everything fell apart.

I tried a few things to try and get a new ROM to install but nothing has worked. I have done a factory reset to clear data and wiped the cache but this seems to have made things worse. Before I broke everything I was able to disable the lagfix but now I can't access the lagfix conf file from clockworkmod!

I am getting the following errors when trying to install new ROM:
can't chown/mod /data/app operation not permitted

What have I done? How can I fix it? I want my phone back!!
I have read on another post for another phone that I will have to restore using Odin. I can't seem to find any information on restoring to stock for the Galaxy S.

Any help or advice would be greatly appreciated.

thanks


EDIT: I'm in Australia and the phone was originally locked to the carrier Virgin Mobile.

I am not sure, but I will tell anyway. It is up to YOU to try it or not.
Enter the recovery mode, format your internal sd and flash a new rom.
I don't think it has to be original, but you can find at samfirmware.com, or something like that.
Hope tou can have your phone back.

me too i forgot to disable the lagfix and everything is screwed now. I even flashed my stock 2.1 firmware with odin, and no luck. I searched all over and im not a noob but i couldnt find any solution for it, thats why i just returned the phone to Bell and theyre gonna fix/replace it for me.
