Community firmware for the Xteink X4 e-paper reader

Oh this is very cool. I've bought one and plan to use it to show some kind of status around the house.

Be aware that Xteink is locking down devices sold for the Chinese market (which includes those being sold on e.g. Taobao). If you want to run crosspoint, you should probably order your reader direct from Xteink.

I ordered the Xteink X4 not knowing about CrossPoint and I was so disappointed with the included firmware:

- Almost no formatting on the ebooks you upload (no bold text, missing glyphs, no images/cover art) - The book had to be rendered before being uploaded. I suspect they were uploading series of bitmaps. - This meant if you wanted to change portrait/landscape or change font size/type you had to re-render the book - Bitmap fonts were very ugly.

Overall it was barely workable. More of a proof of concept. The CrossPoint firmware on the other hand:

- Actually renders books as you would expect, in a pleasing manner, formatting and all - Much more reader configuration on device: font settings, margin, spacing, alignment, progress display - Update via USB or OTA - Multiple ways to get your books: Connect to your Calibre library to push or pull books (thanks for introducing me to Calibre!), USB, Wireless file transfer - Sync progress via KOReader

It's the best gift the community could give to the manufacturer. With only the default firmware my X4 would have been in the junk drawer within a week, but now I carry it every day, I've shown it to so many people. It's a marvel. With the news about them attempting to lock it down I can't recommend it anymore. Why would they do that?

I’m running Crosspoint on the X3, and am quite pleased with both the software and hardware. It even supports reading progress via Koreader sync, which I use on my main eInk devices.

I wish there was a framework style open e-ink device.

Really nice device, I'm just waiting for a version with front light.

I'm quite frustrated to hear that Xteink have decided to block firmwware being changed on some devices. I can only imagine the reason would be consumers who look for support after something went wrong but it's frustrating for those of us who just want an open eink device.
