Well I managed to download the latest BIOS from the lenovo site, which
includes an ME update now the issue is that I can't seem to figure out
how to extract it from the .FL1 and .FL2 files.

Those might have a length too long to fit a flash so you need to trim
those down before using ifdtool on those (If they contain and ifd of
course)
so depending on size of rom
dd if=FL1(or 2)file of=vendor_bios.rom bs=1 count=xM

and then ifdtool -x vendor_bios.rom

It didn't work :( after that still "no flash descriptor found in this image"

These are the files and the flash chip on the board is 8M
8523776 '$01CB000.FL1'
8523776 '$01CB000.FL2'
8523776 '$01CB100.FL2'
All of them have different hashes, but I do not know what makes them different (maybe it is for various board revisions?)

I would also like to know as to how I can re-flash the EC firmware if
that could potentially cause problems, I of course do not know if it
has DMA.

Only existing tool to flash EC is using vendor tool.
EC are only accessed trough port mapped IO (or on newer ones also via
memory mapped IO). EC itself does not have DMA afaik.
