If you want to update the bootloader with JTAG, use the .rom-files.
If you want to update with the bootloader itself, use .tft-files.

Bootload.000

Bootload.000 is needed if only the uLoader was burned to flash:

mt6uloader.rom

To burn a complete bootloader copy:

bootload.000
a matching bootloader .tft-file (see above).
and a autoboot.bat with following contents:

mmc_boot mt664.tft

to a SD-Card.

Insert the SD-Card and turn the device on.
Wait until the new Bootloader got burned (See output on COM1: 38k4 8n1).
