Ya, I tried this awhile back with a non BC 80gb phat ps3.
I didn´t have much luck with the games I tested. they booted but were unplayable. Unfortunately the laser died before I could do alot of testing.
I tried it with OFW 2.52
It would be great and alot more pratical if it worked on 3.55. well it does but you need cobra. So we know it´s possible. maybe with a payload on a dongle and some minor tweaks in the CFW? lol, theories are easy, it´s the getting it to work that´s the hard part.
I´m not up to date on some of these apps but wasnt there a FW loader app?
Would it be possible to load FW 2.5 and then run the boot_ps2emu.pkg app that svenmullet mentioned? avoiding the need to be in Service mode and downgrading.

what model of ps3 do you have? Unless it's a phat or very early model slim, you're not gonna get 2.50 working on it Mine's a CECHP01 and I can apparently go down to 2.45 at the lowest, I think the first slims shipped with >=2.80? Try installing 2.60, it still works for me to play ps2 games (anything after that was a no-go) Also, are you QA flagged? Makes the firmware installation easier. (just go to recovery instead of FSM)

I don't think anyone updated Jaicrab's firmware loader to work on 3.55 though
Maybe try loading Lvl2_kernel.self from 2.50 on 3.55 using the Rebug tool that was just released? I'd try it, but can't figure out how to fully extract the PUP to get the needed file(s) I dunno, just tossing out ideas

[VIRGIN KLM]

You need to patch something on vsh.self on higher firmwares than 2.50 for it to work.
You could try with the "pst" selfs, inside the Cobra CFW if you want too...
pst must stand for Playstation Test.

Has anyone tried using jaicrabs loader with 2.50 OFW dev_flash on slims? i suppose it could work

[svenmullet]

Okay, I managed to extract Lvl2_kernel.self from the 2.50 PUP, and loaded it in 3.55. *beepbeepbeep* led flashed yellow a couple times then blinking red. I even tried setting app version to 3.55 with Lordself, still no go. I just don't understand enough about the firmware to accomplish anything here, and I still don't know how to extract the ps2emu files from 2.50. There is a script that completely extracts the dev_flash from PUPs out there, but it's for linux and I'm not installing linux just to get 3 stupid files. Could someone who's capable *please* fully extract the 2.50 PUP for me?

sven, do you have a flasher? do you know what you just did to your console?

i'm gonna guess you do cause you aren't freaking out like i did when i had something like happen

No, the console is fine, I used Rebug's Lvl2_kernel loader

Further updates:
-Tried making a 2.50MFW with PS3MFW Builder, it gives an error
-Making a 3.41MFW right now to use Jaicrab's FW loader to load 2.50 dev_flash (when the kind person above gets it to me)

This seems like a ridiculous way to get PS2 games booting right now, but there is a method to my madness

@OP

Do you have some video proof?

[JOshISPoser]

sven, if you can get it to work, it'll all be okay.
i'd be in your boat constantly working on trial and error if i could (no accessible computer)
