Hello:
I've been having some problems to have KOReader working on
Boyue Likebook Mars (Android 6.0.1 based e-reader, firmware v2.3.0), since installing the currently available version v2020.03.2 (from
GitHub) didn't work on the "Mars"... and the version installed from Likebook App Store is v2015.11; a working version for this device, to be sure, but rather dated.
However, what
did work was installing GitHub's v2020.03.2
on top of the already installed Likebook App Store's v2015.11; after a reboot, the overwrited/updated KOReader is now working perfectly on the "Mars".
As "recipes for installation" go, this wasn't so bad: I'd like it to be more straightforward, for sure, but it is simple enough; for the forseable future, I'm content with the results and I hope that this will help other people in similar straits.
Kind regards,
[INCANUS]
