Custom Firmware Looking for custom firmwares? There is a dedicated directory for that.

98 Upvotes

Hey everyone.

I constantly see questions popping up on the sub about where to find custom firmwares, which one to choose, or how to get specific features working on your device.

Instead of digging through months of old threads or dead links, I just wanted to remind you that there is a dedicated Firmware Directory over on ReadMe.club.

We actually just crossed a cool milestone: there are currently more than 10 different firmwares listed and categorized.

This includes everything from the latest official stock updates to community favorites (like CrossPoint) and specific niche patches. You get all the release notes, features, and safe download links neatly organized in one place.

If you are a tinkerer and want to browse what's possible with your device, you can check out the full list right here: 👉 https://www.readme.club/firmware

(Also, if you are a dev or just know of a custom firmware/tweak that isn't on the list yet, please feel free to submit it via your account! The goal is to build the most reliable, centralized library for everyone).

Happy tweaking!

Image Introducing the X3 to my mini EDC family

Post image
141 Upvotes

I got the X3 a couple months ago and have used it a lot. I've read from start to finish Stoner by John Williams, excellent book, a good book if you want to get back into reading. Since then I've also been jumping between books.

I'm currently reading "American Hagwon" by Min Jin Lee, came out a little over 2 weeks ago! I only started reading it yesterday and the story immediately sucked me.

I'm in love with the X3, I've gotten a few people asking me what it was, or they've recognized it from an ad somewhere and asked me questions about it. I've convinced 3 of my friends to get either the X3 or X4 and they love it so far!!

For those interested, my other devices are:
- RICOH GRIII: A really compact camera with an APS-C sensor, takes high resolution photos, great for hiking and street photography. I'm using a carabiner as a handle that's surprisingly comfortable and cheap. I love it because it comfortably fits in my pocket, easy to pull out and take a photo, and easy to transfer to my phone using their app.
- FunKey S: VERY tiny handheld console that runs games up to PS1 and some N64 games like Super Mario 64. I actually beat SM64 and Silent Hill for the first time on this little thing, and a number of Pokémon Rom Hacks too. I don't play it too often these days but when I do I'm either playing Pokémon Lazarus (an Emerald Rom Hack) or Tetris GB.
- iPhone 12 mini: bought this refurbished back in 2022 and still using it to this day. No point in upgrading it since there are no good new phones these days. They're all way too big and upgrading to a 13 mini seems to be only a small upgrade.
- AirPods Pro 2: It's nice :)

Discussion Built my own page turner

Enable HLS to view with audio, or disable this notification

• Upvotes

I have a X4 Pro and wanted to get a page turner. But i thought maybe i could make it myself (for context, i have no background in electronics at all. And this is the first time i have made something like this. So i followed a couple of tutorials).

Here are the materials i used:

ESP32 C3 (With bluetooth)

Wires

Cherry MX switch

Keycap

Tools:

Solder & soldering materials

Firmware: Crosspoint bluetooth page turner (beta).

This was the only firmware i could find besides the stock firmware that has bluetooth for X4 pro.

This built isn't finished. I'm planing on adding a battery and make a 3d housing so it looks finished. This built is very, very cheap compared to a Free2 page turner.

DIY More pictures color of the X4 Pro Type-C case!!

You guys asked about the case colors in my last post, so here’s what they actually look like in real life.
I’ve also got two new transparent colors: white and moss green. So far, we’ve only tried them on the X3 case, and they already look pretty cool
Now I’m going to try printing the X4 Pro Type-C case with these colors and see how they turn out. If they’re transparent enough, I think you might even be able to see the Type-C plug through the case when a cable is connected.
I’ll share the results once I’ve printed them!
You can take a look of it here:

DIY Just wanted to share how I saved myself from buying a new light

Yesterday I had received the clear case for my X4 (which I will be using with the folio case by slowly stretching the hinges) and some magnetic rings

If you have a booklight that isn’t able to stick on to your reader, just use the little end bits of the magnets provided!! (I had three so the extra one on top could be used with the folio case)

I superglued mine on, and they have a super strong hold so it doesn’t shift when lying on the side :)

To be honest, I wouldn’t have gotten a new light but it would have definitely been a pain trying to figure out how to use the current one with the clear case

I’m already in the habit of reading on my Kindle Paperwhite before bed, but I’ve managed to make that habit even better with the X4

Now, every time I reach for my mobile, I pick up the X4 and start reading, even if it’s just one page. Another thing that’s helped is that on my Kindle I’m only reading books in English (my second language), whilst on the X4 I’ve only got books in Portuguese, so I can read two books at the same time without breaking my immersion.

So, this is just a personal experience that might help anyone who hasn’t yet decided whether it’s worth having both a Kindle and an Xteink.

Question How to go back to the original operating system on a X4 pro?

Post image
5 Upvotes

My Xteink X4 Pro arrived today, and I immediately tried to download Crosspoint. I struggled quite a bit because my e-reader was locked, but when I finally managed to download it, I wasn't entirely thrilled. When I wanted to go back to the original system I got stuck, I try to do it following the instructions of a page but I think there is not .bin of the X4 pro yet I think. Can I factory reset it? Is it possible? will that solve the problem? I don't care of the content it has because I can upload everything back I just want the original system back.

Troubleshooting Always annoyed when reading

Post image
• Upvotes

My xteink is x4 pro. First 2 or 3 weeks, the words are sharp and can read cleary. After 1 month, the words are becoming faded and need more effort able to read. I don't like complex. So i don't change another firmware and used original stock firmware. I am now frustrating and thinking about going back to my 9 yr old kindle.

Ps. I can only order chinese version xteinkx4 pro in my country. I heard some that chinese version may not install crossink or ... I don't know much about that tech. So I still stay with original stock firmware.

Inspired by posts showing off their EDCs with their little buddies. I get way more external reading done with it always on hand. I keep multiple notebooks and at the end of the day I hardly realise how up-to-date I feel with my work with time left to spare for hobbies like gaming and tinkering. :)

Discussion The X4 Pro has highlighted what I really want in an eReader

22 Upvotes

I've used eReaders since the 2nd generation Nook and I've always been chasing what the perfect eReader would be. I think the X4 Pro and particularly the community around the software has finally allowed me to put my finger on what a perfect eReader would be for me. I want something with the build quality and hardware features of the newest Kindle Paperwhite (aluminum shell, 300 ppi screen, etc.) but none of the Amazon ecosystem. I want to be able to use open source OSs to tailor make the software experience to me. The X4 Pro is literally the closest to this right now and I'm actually hoping that XTEInk decides to expand into full size eReaders but focuses on feature rich hardware but the freedom of supporting open source software. If I'm ignorant of an already existing option then please let me know!

Question Firmware that allows comic book/manga

2 Upvotes

I'm looking for firmware that allows comics and manga easily, currently using crosspoint and I like the minimalism but converting for instance a .cbr file to .epub doesn't seem to be working. I'll also take suggestions for converting files if need be, but I've tried a few times and it seems to result in blank or images with lines instead of the comic/manga panels.

TIA

Troubleshooting Unable to Revert X4 Pro Firmware

0 Upvotes

I recently bought the X4 pro in China.

For experimental purposes, I flashed crosspoint via the unlocker tool. Originally, I had hoped to find a CJK supporting fork to then flash onto the device for Chinese books. In the end I decided to revert back to the stock firmware.

However, I’ve realised that I am unable to connect to the pc with the usb connector (serial port not detected) and can no longer install the stock again. Does anyone know how I can fix this?

I’m a dedicated Kobo Stan now and forever. Have a KLC and a KCC, and I love them both.

I wanted a small BW ereader, and of course, this pops up on my feed.

I was on the fence until Amazon discounted it to $58 and was like why not?

No kidding I got my gray X3 in mere hours lol.

I initially didn’t like it. It was the horrible stock UI. It was terrible. But when I installed CrossInk - holy moley it was transformative.

Once I customized the fonts and layout, I was falling in love 😍.

If they made a backlit model, it’s likely an instant purchase.

It’s so cuuuute 😍😍😍

Question New to small e-readers and looking for font suggestions

6 Upvotes

Just grabbed an x4 Pro and I'm really liking the compact size compared to my bigger e-readers.

I’ve been using Crosspoint on it and it's mostly great, but the constant AA loading on every page is driving me crazy! I thought I’d get used to it, but since I’m turning pages way more often than on a physical book or a larger device, it’s getting really distracting.

I’m turning AA off to save my sanity, but I'm wondering if there's a specific font setup that works better for it? Or a font that works better without AA?I’m using Bookerly right now, which I side-loaded myself.

Thanks for the help!

My main ereader is my Pocketbook Verse Pro Color. It’s portable and light enough but with a case + pouch for protection, it became heavier and bulky. Ever since I got the X4 Pro, I’m happy that I can leave my Pocketbook at home because the Xteink is so much lighter and so much more compact. It’s also my first ever experience with a b/w e-ink screen ereader and first experience with a flush screen. Great experience for both. Here’s to wishing xteink will come out with an X4 Pro Color in the future 🎉 (for those of us who like to see our covers in color 😁)
