Hi.

Check that HD is properly seated. Take it out, reseat it. Insert screw to lock it in position and try to boot again.

(Also this should be posted in pro section)

It’s already seated properly the screw wud never go in if it’s not in line any suggestions?

Try to get some washers and put them under the cpu clamp and try again. if this does not help u might have to do more serious work on the console. BGA reballing stuff.

Wat I have heard and from wat videos I be been watching on YouTube this clamp thing works only with the fat models, they don’t work with slims or the pros

This happen to me today
