Stuck at Huawei Logo after update...

My T2 BGO-DL09 is stuck at the Huawei screen after update.

It will not allow me to go into recovery mode.

It will not restore firmware from USB.

It’s not picked up by PC even when on.

It will not shut down but will switch on automatically when hard shutdown is performed.

It restarts but will get to the Huawei screen and stay there until battery is flat.

It will only stay off when the battery has runs down completely and the battery is charged again. But the moment you start or try to get into recovery mode it will start the boot loop / stuck screen again.

Any idea what to do or is this a lost case?
