3.41 NAND Preloaderdumps downgrader patches

Venix Autopatcher
Warning
| Warning |
|---|
| This tool is known and proven to give false positives on bad dumps that lead to permabricks.
Use this method: Validating flash dumps to make sure the dumps are in crisp condition. You cannot recover from bad flash without proper dumps (e.g. bricking the console beyond repair). |
Intro
Some portuguese dude (somehow venix name reminds me of a fake bricker CFW and highly hyped and never released manager long time ago) apparently never found ps3devwiki guides or used flowrebuilder/winskeet autopatcher or hexeditor with autopatch scripts.
Versions

Tests
Time for some tests, like I did with E3 Nor dump checker.
Quick bulletproof test
does not test:
- bad region - not detected, user not warned -> result = brick file
- bad A9 wire - not detected, patch file created -> result = brick file
- bad A10 wire - not detected, patch file created -> result = brick file
- bad A11 wire - not detected, patch file created -> result = brick file
- bad A12 wire - not detected, patch file created -> result = brick file
- bad A13 wire - not detected, patch file created -> result = brick file
- bad A14 wire - not detected, patch file created -> result = brick file
- bad A15 wire - not detected, patch file created -> result = brick file
- bad A16 wire - not detected, patch file created -> result = brick file
- bad A17 wire - not detected, patch file created -> result = brick file
- bad A18 wire - not detected, patch file created -> result = brick file
- bad A19 wire - not detected, patch file created -> result = brick file
- bad A20 wire - not detected, patch file created -> result = brick file
- bad A21 wire - not detected, patch file created -> result = brick file
- bad A22 wire - not detected, patch file created -> result = brick file
- bad boardID - not detected, patch file created -> result = brick file
- bad bootldr - not detected, patch file created -> result = brick file
- bad cCSD unreferenced area - not detected, patch file created -> result = brick file
- bad cISD unreferenced area - not detected, patch file created -> result = brick file
- bad EID unreferenced area - not detected, patch file created -> result = brick file
- bad header - not detected, patch file created -> result = brick file
- bad header asecure loader - not detected, patch file created -> result = brick file
- bad header cISD - not detected, patch file created -> result = brick file
- bad header cvtrm - not detected, patch file created -> result = brick file
- bad header eEID - not detected, patch file created -> result = brick file
- bad header metldr - not detected, patch file created -> result = brick file
- bad metldr - not detected, patch file created -> result = brick file
- bad/missing bootldr - not detected, patch file created -> result = brick file
- bad/missing cCSD - not detected, patch file created -> result = brick file
- bad/missing cISD0 - not detected, patch file created -> result = brick file
- bad/missing cISD1 - not detected, patch file created -> result = brick file
- bad/missing cISD2 - not detected, patch file created -> result = brick file
- bad/missing EID0 - not detected, patch file created -> result = brick file
- bad/missing EID1 - not detected, patch file created -> result = brick file
- bad/missing EID2 - not detected, patch file created -> result = brick file
- bad/missing EID3 - not detected, patch file created -> result = brick file
- bad/missing EID4 - not detected, patch file created -> result = brick file
- bad/missing EID5 - not detected, patch file created -> result = brick file
- bad/missing metldr - not detected, patch file created -> result = brick file
- bad/missing PerConsoleNonce - not detected, patch file created -> result = brick file
- bad patterned non 00's - not detected, patch file created -> result = brick file
- bad patterned non FF's - not detected, patch file created -> result = brick file
- bad region - not detected, patch file created -> result = brick file
partly test (if user flashes that, it will permabrick):
- bad A0 wire - detected, 00 filled file created -> result = brick file
- bad A1 wire - detected, 00 filled file created -> result = brick file
- bad A2 wire - detected, 00 filled file created -> result = brick file
- bad A3 wire - detected, 00 filled file created -> result = brick file
- bad A4 wire - detected, 00 filled file created -> result = brick file
- bad A5 wire - detected, 00 filled file created -> result = brick file
- bad A6 wire - detected, 00 filled file created -> result = brick file
- bad A7 wire - detected, 00 filled file created -> result = brick file
- bad A8 wire - detected, 00 filled file created -> result = brick file
- bad header IFI - detected, patch file created -> result = brick file
does test:
- circulair reference - errors out: "The process cannot access the file '\nor-validationtest\venix.bin' because it is being used by another process." -> result = OK
Conclusion
Conclusion : USELESS, brickdumps will still show as 'valid' and corrupt patch files will be generated, not preventing the user from permabricking.
Recomendation
Recommendation: Validate flash dumps first and use Flowrebuilder or Winskeet with autopatcher instead.

Note
ps3devwiki v2 downgrader contains 2 patchsets, used on 3 offsets. Having 9 sounds like a bit of overkill to bloat the binairy.
Checks
There is not much checked in the patcher: - only size is checked - and header "oÿà" (bytereversed, like with progskeet, teensy etc) versus "àÿo" (as E3).

Thus it fails miserably in the comparison of Flowrebuilder' options like un/rescramble + de-/interleave, bytereverse, unpacking and autopatching, while checking and informing the user about possible errors in the dump.

Conclusion
USELESS, 100% valid files will be failing 00/ff check. Improper files will be failing 00/ff check too, and no detection of the root of the cause. Nothing was patched and gives the user a permanent false sense of having bad dumps without leads of what to solve.
