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.

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.

Credits to KaKaRoTo for sharing the information.

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.

Hello, first thanks for your work, about actual (and discontinued) homebrew, somebody knows how to resign to work in 4.1; What i mean? a software or procedure to take a pkg, decrypts, resign (or do the required modifications to work in 3.6+ FW) and encrypt again to be able to install and full work in 4.21 CFW.

Thats the private key for appldr from firmwares 0.92-2.36. And

might be correct, as 3.56 was the last version with the ECDSA fail from sony.

Hmm nope, I was wrong, 3.55 was the last time we could get the private keys for games. We don't know any private keys from games that got encrypted with the 3.56 keyset. We can only decrypt them and ONLY encrypt them for FWs up to 3.55.
