@perisiana: If there's an issue with the FW picking stuff up in hidden folders, it's *conceivable* that the processing of the actual KFMon/Plato/KOReader images was delayed, which would explain the "still processing" message.
I'll see what happens on my own H2O shortly

.
I assume when you say Plato still doesn't work that you mean that KFMon is still spitting out a "still processing" warning?
(In which case, since the KFMon button works, could you tap that, and PM me the logfile it'll have created in .adds/kfmon/log/kfmon_dump.log ?)
