I got a DS down, but finally, after research, I wonder if it is not simply bricked.
The guy who I recovered from told me after an exchange of large files via Bluetooth between the tablet and DS, this one was completely blocked until turn off.
Since then, it has never turned back. But now that I have connected it to the PC or charger, the indicator (orange) battery lights up.
This is a good sign? or nothing to do?
Thank you for your help.
