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


77w 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: PS3 4.21 LV2 Patcher / PS3 4.21 LV2 Patcher (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.

Following up on his previous updates, today PlayStation 3 developer JjKkYu has released TrueAncestor EDAT Rebuilder v1.42 followed by v1.45 with the changes outlined below.

Download: TrueAncestor EDAT Rebuilder v1.42 for PS3 / TrueAncestor EDAT Rebuilder v1.45 for PS3

The newest version, but for some reason some function is ripped in the public version.

For detail changes, please read history.txt in the package.

Changelogs:

v1.45
1. Fix bug in rebuilding edat version 1 files.

v1.42 Public Release
1. Batch mode is disabled in public release.
2. Compressed EDAT support is disabled in public release.

v1.41 Internal Release
1. Support rebuilding non-compressed zero content edat files.

v1.40 Internal Release
1. Fix bug in rebuild process.

v1.35 Internal Release
1. Use flatz' rap2rifkey.exe to get rifkey now.

v1.31 Internal Release
1. Fix file missing when failing to rebuild files.

v1.30 Internal Release
1. Change rebuilding method.
2. Support rebuilding compressed edat files.
3. Add generate unlock edat function.
4. Add backup files switch, default is off.
5. Add skip java check.

Finally, in related PlayStation 3 hacking news pink1 has made available an R2R+Edat tool followed by a R2R+edat v1.0.1 update with details below, as follows:

Here is a tool I put together. It's pretty much rap2rif, rif2rap and an edat fix tool for C00 type demos. Put your act.dat & idps in the data folder and you're ready for rap2rif & rif2rap. To fix C00 type demos input a .pkg from a C00 demo or the PARAM.SFO and it will output the fixed .edat.

Download: R2R+etat.zip / R2R+etat.zip (Mirror) / R2R+etat_v1.0.1.zip / R2R+etat_v1.0.1.zip (Mirror)

This is a small update to R2R+edat, it fixes edats being a byte short & should speed up pkg2edat a lot by only decrypting the first 5MB instead of the whole pkg. Put your act.dat & idps in the data folder and you're ready for rap2rif & rif2rap. To fix C00 type demos input a .pkg from a C00 demo or the PARAM.SFO and it will output the fixed .edat.

Finally, in related PS3 EDAT news from BuC (aka BuC-ShoTz 1-2013) comes some old EDAT SRC Codes as follows: going through old stuff on my pc, for learning purposes i suppose.

  • line 257 creates edat: pastie.org/8642860
  • incomplete only decrypt EDAT.cs: pastie.org/private/6k2xiyfcojuch5tg73va
  • OMAC.cs: pastie.org/private/nmsml5958fpacqp1jbyya
  • RAP.cs: pastie.org/private/hqligcidxft7h1evxwfuw
  • FORM1.cs: pastie.org/private/la7dagczv6bpgrbtcappq
  • BigEndian.cs: pastie.org/private/6dr5vvab5f2fgwccjlxow
  • Aes.cs: pastie.org/private/kik3q7oe2vvnayi40l3rdw

Awesome work from JjKkYu (as usual)!

Here are 2 tips to find the dev_klic even faster:

1- First try to bruteforce the edat against the list of known: ps3tools.aldostools.org/dev_klics.txt


2- If the key is not found above, open the eboot.bin with scetool and show the info. Then open the ELF with HxD and cut from the offset 0 to the offset of the 3rd section.

Usually this will reduce the "devklic source file" (elf) to about a 50% or less of the original size, saving a lot of time.

Following up on his previous updates, today PlayStation 3 developer JjKkYu has released PS3 EDAT Devklic Bruteforcer v1.0 followed by v1.1 and v1.2 with details below.

Download: PS3 EDAT Devklic Bruteforcer v1.0 / PS3 EDAT Devklic Bruteforcer v1.1 / PS3 EDAT Devklic Bruteforcer v1.2

To quote: This tool is used to bruteforce devklic for edat files on pc. It supports bruteforcing from binary or text files. It only take minutes to bruteforce in an elf file, no more waiting for hours or days.

This tool is based on BuC's EDAT Devklic Validator, all credit to BuC.

Update to v1.1

  • Fix a bug while bruteforce in text file.

If you meet some issue, please feedback. Thx.

Update to v1.2

Add 2 Modes:

  • Short Mode: Run only 4 rounds for binary source file. This mode doesn't try all the contents from source file. But it is enough in most cases.
  • Line Mode: Run only 1 round for text source file. This mode reads first 32 bytes in each line as devklic. It runs extremely fast for formatted text source file.
