Just unboxed your Xteink X4? Here's what matters most: charge it for 30 minutes via USB-C, then immediately run the firmware update (Sync → System Update). This single step will save you from layout glitches and stability issues. Don't skip rebuilding the index afterward—open any book, hit OK, select Index. These 5 minutes will make the difference between frustration and smooth sailing. Your X4 isn't like other e-readers. It has no touchscreen (that's a feature, not a bug), uses physical buttons for precise navigation, and works best with a well-organized microSD card. The learning curve is about 10 minutes—just enough time to read your first chapter. We've mapped out exactly which buttons do what, how to transfer books the easy way, and which settings to adjust first for the best reading experience. This guide gets you reading in under 30 minutes. From understanding the button layout to setting up WiFi transfers, organizing your library, and avoiding common newbie mistakes—it's all here in plain English. Download the complete PDF and keep it handy while you set up. Your future self (and your X4) will thank you.

Documentation of my findings analyzing OTA file. My goal was to extract system fonts and try to re-implement external non monospaced fonts like system ones. During that I've managed to extract .bin into blocks of system images. Unfortunately I came to a wall and my current hypothesis is that system fonts are using some internal functions we can't properly use for external fonts. Further investigation is needed, as maybe we could prepare OTA file that can pass new font as internal one, which would allow us to use fonts like Bookerly as system ones.

This is documentation of my tries of getting into system files. My first try was on English 3.0.2 OTA which I assume is encrypted and hard to work with. This time I was trying to do it on Chinese version from this hub which seems unencrypted and easier to "unpack" and cut into partition segments. I've managed to do that, but because of lack of variables and documentations in those partitions, I think it would need now to be manually de-assembled. I leave all of my findings in hope someone more competent would find this useful for his own purposes.

I’m really glad you’re enjoying my EPUB → XTC converter: http://x4converter.rho.sh I’ve just added a couple of new features that people have been requesting in comments: Landscape rendering Custom fonts Higher image quality (But really slow rendering - https://streamable.com/d9gi6k) Reading progress bar Faster XTC rendering Keep in mind there may still be some bugs. For example, the chapter percentage isn’t always perfectly accurate so if it's bother you then remember to turn it off. I also spotted that during rendering phase a preview looks broken - but don't worry XTC file should be fine.
