How to Extend the QuirkLogic Papyr’s Useful Life with F-Droid (no rooting or hacking required)


↺ How to Extend the QuirkLogic Papyr’s Useful Life with F-Droid (no rooting or hacking required)


> After reading the announcement from QuirkLogic that InkWorks would be taken offline, and, therefore, that a large amount of my Papyr’s functionality would be eliminated overnight, I went on a quest to find a viable solution. I turned to the dpt-tools GitHub repository, wherein the world’s leading Sony Digital Paper, and, therefore, Fujitsu Quaderno A4 (gen. 1), mooInk Pro A4 (gen. 1), and, indeed, Papyr tinkerers are to be found (since, as I repeated a few times in my full-length review, all of those devices are actually the exact same, simply running different software), asking if there might be a reasonable way for me to re-flash the Papyr with Sony’s or Fujitsu’s respective operating system. I wrote an email to the head of that repository to ask for his assistance directly. I wrote multiple emails to the QuirkLogic team and tried calling their office to ask for help from of them. I asked for assistance in the official Discord server of My Deep Guide, the Youtube channel and services of the well-established E-Ink reviewer Vojislav Dimitrijevic. Nobody responded with any ideas. If someone reading this blog post should have any better option(s) for extending the Papyr’s useful life than what I outline here, please leave a comment below.
