hey so i was in the middle of reformatting my thumby when the screen just turned black... i have since then tried to put games on it and it recognises that the thumby is there but wont make any modifications to whats on it. it wont delete any games or install new ones. i have also tried the manual way of reformatting it with turning the thumby on while holding down on the d pad to open up file explorer and pasting the reformatting software on there. it does so successfully but nothing comes of it the screen is still blank...
