(adsbygoogle = window.adsbygoogle || []).push({}); I'm in the middle of downgrading my ps3 and following the step by step guide and I got to the part were you plug in the usb stick and it should be on and black screen that took hours flashing green light then its supose to turn off after that for me it dident then my power went out for like 5 mins when it came back on I turned on the pse and it just goes on for about 5 secs and turns offf.... Help?

No yellow light just goes form green to red.

Wish i could help. Have you tried booting up the ps3 in service mode with the jailbreak? If that's not possible then i really wouldn't know what to suggest.

I guess that you have wrong .self file. ( 201kt is right one)

1.So you need to Install firmware again like u did before.

2. After it turns of make sure that it is 3.41 (still in Service mode)

3.so now put Lv2diag.self (File 2) to your usb. (delete all other files from usb)

4.After your ps3 turns off-->start without usb stick and enjoy =)

Well, I willl try using the files with the link provided.

It wont turn on so there is no need to start all over again with the downgrade if I cant see screen.. Lol. I may have put in older file.

I also used the one in the E3 Reader guide. I used those files.

Nothing worked.

It's stuck on not loading. It will turn on then power off.

No flashing lights no beeping just turn on 5 secs goes off to red light soild.

I'm starting to think they did patch 3.50 from being downgraded.

??

Maybe it's the ps3? 3.50 cant be downgraded I guess? Thet patched it?

Still would like some help on this.
