Thanks, this is quite helpful. The constant phoning home to China is also my main issue with these devices. When talking about jailbreaking, are you referring to this thread? https://forum.xda-developers.com/t/is-there-a-way-to-root-hi... Because it looks awful, if even doable at best. I'd also ideally like to have some kind of LineageOS on there, but due to the speciality of the eink driver this is most likely far from ever feasible. Another question, is the map really usable in BW? I'd imagine a lot of information and usability being lost by the absence of color.
