Keep trying - do it faster... and the reflasher reports success.. you can disconnect now.
disconnect and twang the power-switch
the software fires up HOORAY!
but then immediately dies as there is zero power on the powermeter....this is despite charging it for a whole day, and plugging it into USB for a whole day a few days ago.. maybe this rebooting stuff drains the battery
Perhaps this whole episode is battery-determined?
Whooooa .. after another reboot it is now showing full battery (whilst connected to the charger)... and all my books are still there ! ??? although its lost what I was reading when it first croaked...
persistence pays off
