@NiLuJe - back in August 2016 (before your hiatus) there
was an issue with the KOA. If it was ever rebooted while plugged into power or with the battery cover on it would restart in Diagnostic Mode. The workaround was in
the last post of the thread. Is that fixed in the latest snapshots? If so, was the fix indeed in the CRP?
EDIT: Does the Kindlet version of KUAL work now? Running 5.8.5
