I work part-time for my university&#x27;s help desk and I was both impressed and disappointed the first time I came across one of these--one the one hand, its highly customizable and supports SSH access. On the other hand, there is shockingly no way to get the MAC address without connecting via SSH, even though this is popular among academics who often need to get onto MAC filtered networks.<p>In hindsight, we probably could have connected it to the guest network, gotten its IP and then had the networking group look up its MAC on their logs. What we wound up doing is telling the user to go home and check their own router for the MAC, which is obviously less than ideal service.

Not trying to shill too hard, but it&#x27;s rare I fall in love with a device the way I&#x27;ve fallen in love with my Remarkable 2.<p>I can&#x27;t say it was 100% worth the price (half was paid as a gift), but everything about it is refreshingly elegant and simple.<p>Great to know recovering from a brick is possible too.

Oh boy do I have opinions with this one. This seems like a lot of work to avoid using a perfectly good package manager <i>on the device</i>.<p>They could have used rsync without installing rsync on the device. The target device doesn&#x27;t need to have rsync for rsync to be used.<p>They could have installed the package manager and left it. It doesn&#x27;t run anything in the background on my device. It&#x27;s easy enough to verify you don&#x27;t have a systemd service or timer running it. (cron isn&#x27;t installed, iirc)<p>They could have compiled rsync with all of the libraries bundled with it. (Maybe this is beyond their expertise?)<p>Their solution is using Docker to use the package manager and then <i>overwriting system files</i> on the device in the worse possible way, without understanding what they are doing. At that point, they verified in Docker. Should be safe to run it on the tablet then, yes?<p>What attack vector are they worried about? :&#x2F; Toltec is actively worked on, odds are someone would notice someone else fucking with repository.<p>The cherry on top was completely not understanding how the remarkable works. There are two partitions for a reason. The inactive one is used for software updates. When the reMarkable downloads an update, it downloads it to the inactive partition. When you &quot;install&quot; the update, it flips which of the two partitions is active. If the update fails to boot, it flips back to the known good state. All they had to do was switch the active partition, the next update would overwrite the broken partition. <a href="https:&#x2F;&#x2F;github.com&#x2F;ddvk&#x2F;remarkable2-recovery&#x2F;issues&#x2F;6" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;ddvk&#x2F;remarkable2-recovery&#x2F;issues&#x2F;6</a><p>This looks like a bad case of tunnel vision, combined with a lack of understanding. I&#x27;m glad they managed to figure out how to fix it.

This just points out one of the more amazing things about the reMarkable 2 is just how hackable it is. I have never had to do this level of surgery on mine but I do enjoy the community support for interesting scripts and such.

My only regret about this device is that it seems to lack full disk encryption on the device or any meaningful privacy (encryption) for documents stored in reMarkable Cloud...which is all of them if you want to use features like Screen Share (f.k.a. LiveView). ReMarkable should not be able to access contents of docs backed up from my device without my password or recovery key, but AFAICT, there is no such protection whatsoever against internal threats.<p>Other than that, I love my RM2, just can’t use it for as much as I’d like because of the above.

Isn&#x27;t `bricked then recovered` a contradiction in terms?

Back in the day “bricked” meant it was actually and permanently about as useful as a brick - no chance of recovery. These days it just seems to mean “can’t boot and can’t be fixed&#x2F;reflashed easily”.<p>Having to plug a resistor into the device to put it in any sort of recovery mode does walk a very fine line between “not really bricked” and “dude you squeezed water out of a stone, you are a demigod”.

BTW There are rumors about reMarkable requiring paid subscription for some features available for free now. <a href="https:&#x2F;&#x2F;goodereader.com&#x2F;blog&#x2F;electronic-readers&#x2F;remarkable-is-working-on-a-paid-subscription-system" rel="nofollow">https:&#x2F;&#x2F;goodereader.com&#x2F;blog&#x2F;electronic-readers&#x2F;remarkable-i...</a><p>I love my rM2, but there are decent alternative eink note taking devices on a market nowadays.<p>Maybe I’d buy subsidized rM3 for $200 with backlight, and also nice for it to be waterproof with subscription, but keep asking money from existing owners of rM2 who paid hefty price of $500-600 for device is too much.

I had a very similar problem, although the root cause was a drained battery. After finally charging it, the device was stuck in a boot loop.<p>I wasn&#x27;t able to create a proper connection via the pogo; but the community was amazingly helpful (and appropriately critical of my poor soldering skills).<p>Since the device hadn&#x27;t synchronized to the cloud in some time, I had to send it out for data recovery. The cost was worth it for me. Happily, the data was fully recoverable and I was able to simply get a drive image and work with it locally using a mix of traditional OS tools as well as tools provided by the Remarkable community.

I love my remarkable 2. The only thing that&#x27;s missing for me is a backlight, it&#x27;s unusable in terms of reading and writing if the room is dark. I would instantly upgrade to a RM3 with a backlight.

&quot;The USB-C breakout board with the pull down resistor connected on the bread board&quot;<p>Actually, it isn&#x27;t. The resistor is in row 16 of the bread board, the cable to the connector is in row 15. I&#x27;m sure, you just wanted to test whether we&#x27;re paying attention.

now now, it&#x27;s a kinda obvious screwup, but with big footguns like this there should be an easier way to re-flash the thing though... it really should have a shadow-copy of a partition that can restore it to factory. It wouldn&#x27;t be to hard to implement.<p>it&#x27;s just lovely to seen an open device... this made me want to buy one.

I ran into a similar problem as the author: trying to easily extract highlights without having to go through ssh.<p>I ended up building a cmdline tool to solve the problem and have been using it for a while: <a href="https:&#x2F;&#x2F;github.com&#x2F;sabidib&#x2F;remarking" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;sabidib&#x2F;remarking</a>

That&#x27;s easy comparing to reflash a pocketchip and setting up a pinning kernel because if you upgrade the NAND will bork out as MLC+ubifs it&#x27;s a recipe for a disaster. On similar ARM devices, I own a wm8850 netbook (armv7l) and I coudn&#x27;t reflash it with a custom Uberoid &quot;ROM&quot; but oddly enough I could boot a custom kernel and config with a Slackware 14 rootfs. Some port from PostmarketOS exists (Tokio techbook), albeit is not for the same model, but setting up a similar u-boot woudln&#x27;t be too difficult. My major issue is that that device is now semi-bricked and I think I could restore it with PXE, as it doesn&#x27;t show anything on any reflashing trial.

I got one for drawing sketches&#x2F;designing stuff, I love the drawing feel on it due to the textured surface. Light and lasts a long time, I have a Surface Go 2 as well.<p>R2 with eraser pen and folio was not cheap though.

I bricked the reMarkable 2 within a day or two of receiving the device. And since then it&#x27;s been laying in the cupboard. I&#x27;m grateful for the recovery write up by ddvk, but I&#x27;d really wish Remarkable would make it a bit easier. I understand it&#x27;s not their problem, but looking through the physical recovery flow is sadly utterly confusing if one isn&#x27;t already a seasoned geek. They really should provide the SSH password printed and an easier way to reset the device.<p>I&#x27;d love to give it a try soon. Unfortunately couldn&#x27;t source the required parts from any European online shop. Can anyone help here or is AliExpress the only viable option?

Can I use this as an ssh terminal to login to my development machine? I wonder if the display latency would make it non-starter for this usecase.

Can the reMarkable 2 be used as an extra display for a Linux Desktop machine?
naikrovek超过 3 年前
is it bricked if it can be recovered? bricking, the way I learned the term, means unrecoverable via any software means and almost any (or actually any) hardware means.

So, I guess I&#x27;ll give my (sadly) negative experience with these things.<p>First, I sort of ordered it on a whim. I liked the idea and thought it&#x27;d be cool to use for work while not having to use my personal iPad even more.<p>This is their decision, but they ship with DHL, which is absolutely godawful in literally every experience I&#x27;ve had with them. I learned after ordering that the device doesn&#x27;t allow searching within your handwritten notes, a feature I use regularly in GoodNotes on my iPad.<p>So, I looked at how to return the device before I even got it. Their support said to just tell DHL to return to shipper. I called DHL they said &quot;sure, we&#x27;ll do that&quot; for the next two days I kept getting text messages from DHL saying they hadn&#x27;t managed to ship it back yet, they&#x27;d update me the next day.<p>Then the device shows up at my doorstep and DHL skipped requiring a signature and just dropped it on the porch. Great.<p>So I email support back and get the process to fully return from them started.<p>They send me to a &quot;returns&quot; website that doesn&#x27;t see my order. Great. Email them back and ask for how to workaround this.<p>The next email they send me a second returns site.. they have two apparently. Then this time their instructions are about returning for a replacement device. Email back after that and clarify, I am not returning for another device, I am returning and getting a refund. They said oh sure, our mistake.<p>Their returns site (2nd site) was about as unclear as can be. In fact their instructions in their email were, yet again, for returning for a replacement device, the site said to print 3 copies of one sheet, another one copy of the label to attach to the box. I did so, finally got DHL scheduled to pick it up.<p>DHL says &quot;nope, we need a different sheet of paper&quot; which was not provided to me until I went searching for it in the returns site. At this point DHL is gone with the box.<p>I write some feedback to Remarkable about their incredibly terrible instructions and they just keep apologizing but referencing my replacement device despite repeating 5 times at this point that I&#x27;m returning for a refund.<p>DHL has had the package for over 10 days now and it&#x27;s not moving. My luck, Remarkable is going to get the stupid thing at some point and then ship me a replacement device instead of refunding me and I&#x27;ll have to do this stupid insanity all over again.<p>The device itself seems fine, I opened and used it while I was waiting for Remarkable to figure their shit out on my return as each email takes over a day to receive a response. So I have about a week of waiting to return this thing just in waiting for them to send me appropriate return instructions. Another 10 days of screwing around with DHL and no movement of the product.<p>I would really recommend NOT getting one of these devices unless you are 100% sure you&#x27;re going to keep it. If you have any inkling of an idea that you may utilize the return process, just don&#x27;t, it&#x27;s not worth it.<p>This has been the single WORST customer support experience I&#x27;ve ever had at this point. Their support people simply regurgitate snippets, and sadly they can&#x27;t even use the correct snippets, and for that they take over 24 hours to get back to you with those incorrect instructions.<p>Run, just run away.
