I was already to sleep yesterday, so I didn't see your post. You have to put them all on the root of the sd-card and then do the toothpick method. If everything is alright you should see the picture of the droid with a spinning wheel in his body. If you are still on TWRP it will not work. Then you have to install the recovery.img first from TWRP (if I remember correctly) and then do the toothpick method again.
If you are not sure you can do following command in a linux terminal: cat factory_update_param.aml
It will show you the text inside of the file. With a little imagination, you can read what files the update needs and what it will do.
You can do the same for the aml_autscript: cat aml_autoscript (make sure you cd to the folder where the files are located).
I did figure this out by looking way back on some Freaktab posts. However, the Tronsmart rom failed via the SD card method. Luckily the box still booted into recovery, as the Beelink firmware was damaged/cleared when trying to boot the Tronsmart ROM. I'm a bit worried to try the USB Burning Tool method, as I am not sure if I will brick or not. I installed an old ROM, 115K4 which was what I was using. Tried an LE 7 rom which would not boot. So a long day spent getting nowhere. Its raining today so perfect day to try again.
