PS3 4.21 LV2 Patcher is Now Available, Sign and Run Homebrew


Sponsored Links
104w ago - Following up on the PS3 4.21 EBOOT Resigner SCETool Script, today I am releasing a PC tool called the PlayStation 3 4.21 LV2 Patcher.

Download: [Register or Login to view links] / [Register or Login to view links] (Mirror)

Basically what this does it disables lv2 from using the appldr to check homebrew. This will allow you to sign and run homebrew.

Just for a heads up. This has about no use to the average user because you need the lv2_kernel decrypted for this to work.

How to use:

  • Press the big button in the middle.
  • Located your file.
  • Open it and you're done.

Finally, those looking for some more PS3 4.21 CFW homebrew may wish to check out Comgenie's Awesome Filemanager v0.06 for PS3 4.21 CFW, BlackB0x FTP V1.2 for 4.21 CFW / ReActPSN Rogero Fix for 4.21 CFW and Several PS3 CFW 4.21 Homebrew Ports.

Here is a follow-up from his blog today as well for those following: nwert.wordpress.com/2011/11/29/about-spu-channels-64-72-and-73/

If you are reversing the PS3′s isolated SPU modules, you will eventually notice channels 64, 72 and 73. Here are some C functions, that roughly describe how they work:

About SPU channels 64, 72 and 73

It seems that lv1ldr is storing it’s version into a special storage area.

And e.g. isoldr reads the version from the storage area and compares it to it’s own version. If the check fails, isoldr will just stop execution.

I wonder what else is stored in the area and how long the data in it persists, so my next idea is to code an isolated elf, that allows me to specify the value written to channel 64 and then dumps the data from channel 73.

Yep. WE mortals don't do nothing with this stuff. But i suppose it's an advancement about a free solution...

Oh, some news: And no, I won't release eidtool. If you want the algorithms, you'll have to start reversing

Cool, we can close this chapter too
