Not sure what this one will end up being called, but I wanted to give some information on it.
The log file that remains on the device when I inspect the USB drive manually is and update called "update-J140001-bellatrix_malbec-006.bin" which contained
Code:
mt8110_bellatrix\u-boot.bin ( and sig )
mt8110_bellatrix\boot.img
mt8110_bellatrix\b12.img
mt8110_bellatrix\tee.img
mt8110_bellatrix\quickboot.img
rootfs.img.gz
update-payload.dat
If tee.img and b12.img mean anything to anyone, I thought this could be useful.
