Newbie asking question and saying thanks

I am a newbie at this stuff. I crossflashed my 111d to a 111(shows in Device Manager) using the firmware A11 from TDB and everything works great. Now I would like to say from this newbie to TDB.

Thank You VERY VERY much

Now for the question. What is the difference in crossflashing my drive to a 111L and crossflashing using the A11 firmware.
