So you have used this method. I remembered the last time I checked the program needed a special key. I take it the problem has been solved. Modifying the kdz to a single bin is quite easy. I'll tell you how to make it later. Or I'll just upload the kdz you want already set.

Just curious, what changes did you make so it would operate? Just so you know, jes batch script is not setup properly for L9 kdz. It doesn't combine the bin files in the correct order. The script I put together will combine the kdz properly.


Update
I see, so this process is suppose to flash ice cream x & u with LGFlashtool but it doesn't flash the system, correct.
