I've tried the Juffo ROM but don't like it and want to return to the stock ROM. Funny thing is whenever I use Odin 1.85 to rewrite the stock firmware downloaded from the initial link in this thread, I end up with a bricked set. I'm using the I9100G. I reach the part where it says something about Write failed after a line which ends with LOKE. I then have to flash with the original kernel to get the set working but I'm still left with the Juffo ROM.

Any ideas why?
