After upgrade firmware unaccesable

My Cloud OS 3 Personal & Network Attached Storage My Cloud EX4

After an upgrade of my firmware to My_Cloud_LT4A_2.12.127 my WD Ex only give “Welcome to WD MyCloud Ex4” as message and that’s it.
No blue lights are blinking or lightning up.
The buttons are inoperateble.

The reset button on the back looks inoperateable to.

Waiting a few days with power still no activity.
Unplug the power for 1 day still no activity.

Does anyone knows what to do or is this the end of my WD Ex4

desperate waiting for a solution,

Something similar.
After updating, in another situation, the message “Welcome to WD MyCloud Ex4” appeared.
Only by unplugging My Cloud and then plugging in did the message disappear.
But the DASH is very slow after this update.
I am thinking of downgrading to 2.11.178
I hope you solve it.

Did you ever get this working? I have the same issue with an EX4.
