Upload these hex files via an older version of micronucleus or some other attiny85 bootloader like fast tiny & mega uart bootloader, and when the program runs it'll brick the chip, patch the bootloader with a new version, then patch it's own interrupt vector table to point to the bootloader. After letting it run for at least five seconds, power cycle the device and it should boot right in to the new bootloader! + o I (bluebie) make no guarentees that any of micronucleus wont brick your chips.
