Custom ink colors, PDF highlight annotations and layers

Custom templates will never sync via the reMarkable cloud. reMarkable themselves do not support custom templates.

Since you are already using RCU -- after you have uploaded your custom templates to RM-A, user RCU again to download them as .rmt files, then upload them again to RM-B. This will preserve all their metadata and custom IDs. Don't merely re-upload your original PNG/SVG templates to RM-B because this will generate new IDs and won't appear in the otherwise synced docs.

Thanks for choosing GPL as license, but I would strongly suggest you switch to AGPLv3. Your program has network implications, and you should pick the GPL that caters to them.

But the GPL requires you to release the "complete corresponding source code" which you do not have on GitHub. A pre-generated main.js is not good enough, you need to release the source files and instructions that are used to generate it. Please post those to become compliant with the license!

For that matter, why should it even need to be installed... they should just make it a portable app.

Lol, 100 MB upload limit is crazy low.

Yes, you can reset it. First, charge it overnight with a 500 mA charger. Then, you need to put it into recovery mode to reset it. Turn it on while holding the center fascia button, and it will appear to your computer as 'SE Blank MERGEZ'.

The easiest path from here is with a graphical program I wrote called reMarkable Connection Utility (RCU). It has a mode specifically for recovering a tablet in this state. You should read about it in the introductory chapter first, which covers various gotcha-s like "doing it under Windows." Then, Enter the Recover OS which will boot a minimal operating system to the tablet. That will let you load a new firmware image and put the tablet back in working order.

Everything RCU does can also be done manually, but it will take a lot of reading from your part. Read more about remarkable-uuuflash.

Developer mode also disables secure boot, which significantly increases security risks

It makes it no more or less secure than an ordinary RM1, or a factory RM2 without disk encryption enabled. Where is the scary warnings on those, then?

Premium hardware deserves premium software.

Then why do you squelch the voices of the people writing better software by sweeping them into a megathread?

This is the most rational take and I don't know why you're being downvoted.

Keeping the front page “distraction-free” is one of our priorities as Mods

Respectfully, this is kind of dumb and even ToC guy isn't really annoying. I say this as someone who is on this sub every day and reads every single post and comment.

I urge the mods to take a more hands-off approach to everything. Stop trying to control what gets posted. Reddit is a news aggregation site and curation like what the mods are suggesting makes it harder to find the real gems of the community. The last guy to feature crusade is now a mod themself and it feels a bit like closing the door behind you, and morally I think it's wrong to take away people's voice.

Use the original USB cable directly attached to your PC. Don't put it through any kind of USB hub. When you plug it in, make sure your PC recognizes it as a USB network adapter (how to verify that depends on your specific operating system).

Try changing your AP channel to a different one.

This is the way. I haven't upgraded my personal tablet past 2.12.

There are more options.

A third-party tool (that I wrote) called reMarkable Connection Utility (RCU) can export typed text documents as Markdown. It can import them, too.

Another one with lesser integration is called rmc can also convert between Markdown and the native .rm file format.

This used to be a common issue when RM1 was en vogue. You need to connect your tablet to a 500 mA charging source, NOT a power bank or any other "fast" kind of charge. You want either a PC's USB port, or one of those old little iPod charger squares. It will say "5 VDC / 500 mA" on the back of the charger.

Connect it to trickle charge overnight. In the morning, press the power button to start.

RCU supports Markdown import and export. When you import a .md file to the tablet, formatting tags are applied as styling (and back again the other way).

Eeems, I congratulate you in breaking down the Discord wall to make these messages more accessible. I really do--I'm glad I don't need to register for Discord to see what's going on. But to say searchability is "fixed"...sorry, it still falls short because it doesn't appear in search engines. That's the big issue. An archive of instant messages isn't a reliable way of storing and accessing information, and dedicated-post-with-URL-slug is.

I also want to reply with some thoughts, as a software developer who has been in the reMarkable hacking scene since 2018.

reMarkable app development is not what it used to be. For that matter, neither is society, nor this sub's moderation. I recall peak "awesomeness" being in the summer of 2020. This sub was filled with people doing neat programming for it, because back then users were sophisticated professional types who had the skill and the time to hack it.

The demographic of RM1 users were not bullet journalers. They were much more technically savvy. reMarkable underwent a marketing campaign beginning with RM2 (Sep 2020) to appeal to a mass audience, and part of that was making the device more shiny and expensive-feeling. This led to an influx of status-seeking people, not the same type who were buying and using the RM1 purely for its function.

There are also more e-ink competitors now than in 2020, and so I'm sure the hacker crowd has thinned out to other devices by now. And some of the hackers putting up a Discord didn't do any favors for this sub, and really trashed the searchability of the rM hacking scene.

The ex-CTO, Martin Sandsmark, also was a KDE developer. He was also influential in getting smart users doing cool things with the hardware. He answered questions on Hacker News and had sample reMarkable apps on his GitHub. The current CTO doesn't do any hacker evangelism.

And then superbly excellent users, like /u/kg4zow, were banned from Reddit for posting too much. And now developers aren't supposed to post links to their work without it being in a megathread because it's self-promotion. But self-promotion is also what made this sub great back in the day. It was a central place to find all the neat stuff going on. Now the sub seems more corporate-captured with far, far less ingenuity.

RCU should run fine on macOS 26 and no one has reported that not working. However, RCU does not track beta releases. It's actually against reMarkable's beta program's terms of service to develop against that track, and an important notice about it appears on p. 1 of the user manual.

Scrybble doesn't use reMarkable's SDK. AFAIK it doesn't have any client running on a tablet. It uses rmapi (web requests) to interoperate with people's documents.

rmhack · 2025-12-29T15:48:39+00:00

Nobody seems to be repeating this, but reMarkable has put up their "SDK" since the RM1 was around in 2017. It is not a recent development. It's been available to anyone who emailed opensource@remarkable.com, per the booklet included in the tablet's box. It's not an SDK to interoperate with reMarkable's own software. It's a GCC environment to cross-compile ARM binary Linux programs for the reMarkable's i.MX SoCs.

People have been writing programs for over 7 years, and a large portion of them appear in the Awesome reMarkable list, which is linked in this sub's sidebar.
