Help! Onyx Boox
T76ML Carta+ "
No device Connected"
After the upgrade it's impossible to start my T76ML Carta+
Now my device doesn't work anymore, Windows 10 doesn't recognize it (no drivers?), so it's impossible to start the process with mfgtool2 tool (it says "No device Connected", when T76ML is in "download" mode).
I tried to install the ADB-tool, but it just says: 'device not found' with the adb command 'adb reboot':
C: \\ adb \\ adb> adb reboot
error: device not found
I don't know what to do now
