Yes the copy from 0x80000 worked for me too! There's a block of just over forty bytes starting at 0x80000 (hex address) that is surrounded by zeroes. Just had to copy that across. But, weirdly I had to hack the 0x80017 value back from 05 to 00 to make it work (otherwise, it just wouldn't boot). I don't really understand how this stuff works, but still seems weird to me that it would be 05 in the Kobo img when it should be 00... Unless I was doing something else stupid! Like I say, total noob, but thought that might help a few people...
This is an amazing setup, it's so much better optimized for the e-ink than was the original Kobo rom! Very grateful...
