Model: M7350 V3.0
Issue:
Router was working one day, and since the day after it is no longer possible, to start the device.
Pushing the power button results in screen showing TP-Link logo, but then it stuck.
Tried to push internal reset button, but no change.
Tried to remove battery for 24h+, but no change.

Menu button does not work, most likely because the OS is not (fully) up.
Also, device does not show up when being connected via USB cable.

Warrenty has ended month ago or so, TP-LINK support did not respond to my email.

Any suggestions?

PS: searched the forum, but nothing seem to fit this situation
