Hello everybody.
I have been experiencing this problem on three different Kobo Libra2:
After the last update (ver. 4.31.19086) if I turn off the device with WI-FI disabled it will block during the next restart and it will no longer be possible to turn it on.
To turn it on again I have to connect it to the PC and hold down the power button. This problem does not occur if the WI-FI is left on.
I tried to downgrade to the previous version (4.30.18838) and the device works fine until I update it again.
Has anyone else experienced this problem?
