I noted that the (2) batteries are newish, but maybe their internal charging-circuitry has locked-up?
I'm not sure, but when the N900 is turned off, the battery may drain 'rapidly'.
When connected to a car-charger, there's 60 mA leaving the battery when the yellow LED glows, and 220 mA when it doesn't , so the phone apparently is charging.
The wall-charger gives a similar result, except the initial 30-second yellow-LED doesn't display.
Before trying Flasher, are there any other tests I could try? - Would RecueOS be useful?
I understand flashing the FIASCO image won't erase the /home/user and /home/user/Mydocs files, but what will it erase? /home/opt? I don't recall what is on the 240? Mb partition.
