Ps4 su-30631-03

Hi, my PlayStation “died” after Sony released an update and since it’s been struggling to install. I keep getting the error code SU-30631-03 and have tried several fixes but none have worked for me. I have manually tried to install the update via usb. I’ve cleaned my PlayStation from any dusting issues not that it should cause a Software Update issue. I’ve changed the HDD to a new SSD in the correct format. Is there anything else I can try?? Before having to buy a new PS4 / a Sony repair?
