Amazing work, I'm going to try and replicate it with mine. The ReMarkable has an amazing writing-feel and the software is just enough to fulfill its core function but it could be so so much more. Disappointingly the company doesn't want to open-source their code and isn't focused on the software side of their product so we're left to patch the binaries ourselves at a snail's pace. On the plus side it's given me an excuse to up my Ghidra skills.

Another thing I've I've noticed is that the userbase is highly skilled, people on the subreddit and discord are constantly publishing hacks and patches and discussing customization options. It's a very cool community.
