I still use my Jolla 1 (JP-1301) with TOHKBDv2
The latest version of TOHKBDv2 from @kimmolindholm here is built against sailfish_latest:
Kimmo wrote me, he will look for the older version, which is build with older SDK.
I think its the version 0.29 or something like this.
If someone has the files - please share!
