@mhoye what was the failure mode? Which model is it?
@mhoye ah, sounds like recovery mode when something crashes like a watch face. Though could be another underlying problem. Maybe try http://pebble-help-legacy.rebble.io/help.getpebble.com/customer/en/portal/articles/2520035-sos-screen1677.html and reflash using gadgetbridge or maybe rebble (I've only used gadgetbridge to flash). A bit of a dance, but might extend its life by a bit
@keverets thanks - I have another one here with a broken screen and I might be able to salvage it.
