PS3-HW My PS3 won't read ant discs even after a blu ray drive swap

Hi guys, I'm new here. I bought a PS3 with a non-working Blu-ray drive, a CECHKO4 model, because I wanted to try to fix it. So I bought another PS3, model CECHL04, with YLOD (non-backward compatible) to use its Blu-ray drive. replaced it using the logic board from the PS3 with the non-working drive, but despite this, the PS3 still won't read discs. Now I'm wondering if it's a problem with the logic board of the PS3 that's working, or if I'm just unlucky and the PS3 I bought with YLOD also has a non-working drive. Yet the disc spins inside the console and doesn't stop and start like it usually does when it has a faulty lens. Can you help me?

If you've changed the BD daughterboard, then you must remarry it. Use Evilnat's CFW Tools (it's easier that way).

There are tutorials here on the forums.

No i actually reused the daughterboard from the previous BD drive as the one from the drive that i pulled from the CECHLO4 had a smaller connector

What do you think Is the problem?
The disk spins and never stops so It can't be the lens right?
