Hi @swinglify
Which fuse blew, in the router, router's power adapter or the house mains supply?
Do you have a DMM (digital multimeter) and know how to use it?
Can't see it too well on the images you posted but could you post another image showing the designation of the two points shown by the red arrowhead in the image below?
If you have a DMM, connect power to the router and check if there is 3V DC on the test point (TP_3v3) shown by the blue arrowhead
