If you Google remarkable hack you get the GitHub with instructions. You’ll need to downgrade to a compatible version. What I’m not sure about is why to hack. I need to do it to make extra features work on the Lamy stylus I bought instead of the remarkable official one. It offered more cloud options without a subscription. I also believe and hope, that DRM and cloud stuff will be better.
Will check it out, I’m charging it at the moment and will have a good play around with it.
