Thanks for the help guys really appreciate your time. But I think I'm gonna leave it! I love my OP1 too much to mess with it :)
TE must have given it a fair amount of thought - should they open up even a little to a software community, and they aren’t open but aren’t strictly shut either (by ignoring this). However, it’s all 100% hacks; not sure if the process voids your warranty, but am also not sure if there’s any way to unbrick it should anything go wrong, and there’s some bootloader mystery already. I’m only certain that there are internal revisions between the different OP1 units for which there’s no public documentation whatsoever, so anyone offering you to send you firmware would be taking on all this risk for something that’s not theirs. If peace of mind is what you’re after, you’ve just made the right call.
