PS3 Having problems getting the syscon error codes form a dead CECHL model

[Kuppi]

I've done this already a few months ago on a CECHC04 and CECH-2504B, and everything worked fine.
I followed NSC Modz's video guide and a written guide with the same things.
On this one, I can connect to it just fine, but all the error logs seem to be empty. Every code is just 00000000 FFFFFFFF FFFFFFFF.
I tried to boot the ps3 again, got the YLOD of course, but the log was still empty. What can I do?

Also, when I try to boot the console with the FT232RL connected, and then run the errlog command, I get this, but not sure what to make of it. Couldn't find a clear answer.

I have the exact same problem, CECHL console, YLOD, empty codes etc. Bringup shows the same. Did you find a solution?
