So far the boot loader is unlocked and you can flash on top of it, although I don’t know why you’d want to since you’d have to rebuild an entire OS but it would be possible. Our waveforms were easy to get right so it’s not as simple as driving the eink displays with OSS drivers.

To add a book you can use a mobile app or text directly since we’re manually buying the books for now. Once we have a book marketplace it’ll be self serve on the mobile apps. We are planning side loading capabilities so you can use the mass storage device, but there’s a bit of preprocessing we’re doing to the epubs that we’ll have to replicate for self serve epubs. To get around that you can email an epub to add@solreader.com and we deliver it directly to your device. Handy!
