I would suggest you install Blackberry Desktop software, then any firmware for it.
Then follow the instruction to upgrade firmware.
I think it should be ok then

Perhaps try a new battery. Or clean the contacts on your current battery with a pencil eraser. Then charge the battery for several hours with a wall charger.
