So far
In USB link package V1.63_110310, downgrade your ESC to V2.0_100518 (Version 2 firmware) OK
Then downgrade your 2 in 1 box to 101224 (V1.07 101224) OK
Then close USB link package V1.63_110310, OK and start USB link package V1.63_101224, here problem, where do you get 1124, because on HW ESC setting thread only link to V1.63 (1224) is loading version: V1.63_110105 (ignore the message about upgrading)
Then upgrade your ESC to V3.0_101224 with 110105 downloaded (1224?) there is no V3.0_101224 as an option.
You should try to instal those HW packages next to eachother on your PC (create a seperate folder before you unpack the rar file) I have already. This give you the opportunity to go any way you want.
