PS3 USB Custom Firmware Loader v0.3 Released by JaicraB!

You could try it, however I think you will just end up with a 3.50 system.

No, with the Infectus chip you can downgrade the fw.

I doubt infectus works with latest FWs ...

Correct, it has been confirmed as not working at PS3 Firmware 2.20... with some users reporting it hasn't worked even a bit before that.

So right now I'm running firmware 3.15 on my PS3. I just copied my dev_flash to my USB drive (and made a few backups). If I now update to 3.41, should I still be able to load my 3.15 firmware from the USB drive?

I don't think you can run 3.15 via the loader, just end up with a black screen.

Please do correct me if i'm wrong here - I've got 3.41 on my PS3 and have a copy of 3.15 dev_flash so would be really interested - just haven't had time to test it any further than the first failure.

If JaiCraB is listening - is there any chance you could change the loader so that the dev_flash can be a folder on the root of the usb device - I use my USB stick for other things and try keeping it tidy

cheers,

I think you're correct. I'm still on 3.15 and tried to use the loader on my dev_flash backup, and it went to a black screen, then back to the XMB.

Yea because we use a custom payload to be able to do something in the background was normally wouldnt be possible. And this isn't simply turn on the dev modus of the ps3. This can happen in case of that the custom payload have get a new systemcall that define to swap the given dir with the dir from the /Dev_BDVD/ or the /App_Home/.

[let us say someone have added the syscall: "sys_lv1_systemcall_Jailbreak" and when this syscall comes into action it will do: replace %1=%2]

Even with CJ´s patch to the Backup Manager there for that also debug user can install and run the hb app you will not be able to boot backups with the programm.

Douring reboot back into the xmb the magic is done and two variables will be swapped with each other.
The Backup Manager set up the following variables:

set /v gamepath=%1
set /v drivepath=%2

and after that he will call "sys_lv1_systemcall_Jailbreak" to the HV and your Backups will be playable.
