Thanks for the link on mobileread. I was not aware of current development in direction of secure boot / chain of trust.

Not OP, but when I was looking for an e-reader, I looked up the Pinenote. I could not find easily a lot of information on its software state. I could find a lot on Kobo hacking. I notably found https://anarc.at/hardware/tablet/kobo-clara-hd/ and this motives me to get a second hand Clara HD for less than 100$. It was way cheaper than starting with 400$ and unknown software state.
