PS3 Frankenstein PHAT PS3: CECHA with 40nm RSX

[SyrianClippy]

Hi guys, I need help on a PS3 COK-002. The PS3 turns on and shows a black screen, and after 20 seconds it turns off by itself. I only notice that before turning off the hard disk's orange LED lights up, without giving a YLOD error and without giving a flashing red LED. It turns on and off, the syscon does not show any errors. Any help is appreciated. I have never had such a strange problem.

Overheating?

I fixed it by performing a clean install of the system using a USB drive in recovery mode.

Probably a dumb question but how did I just frankenstein a PS3 on 2.50? Ive always had issue with anything under like 3.42 FW and a 40nm.

It does appear to have CFW. Is it really on 2.50?

That shouldn't be possible. A firmware that low should give 1701 with a 40nm installed.

Yeah that doesn't sound right, I'm not sure CFW that low even exists. I certainly can't find any .PUPs for CFW below ~3.4X
