mincg

Min. firmware version manager for Playstation Vita/TV

Description

This toolset lets you manage PS Vita/TV's SMI data which stores the minfw ("factory firmware") version.
How does it work? - Check out Moth Exploit by TeamMolecule/xyz: https://wiki.henkaku.xyz/vita/Vulnerabilities#moth_exploit

PC tool

This tool lets you find a compatible signed SMI block for your console.

Vita tool

This tool lets you Flash/Dump the SMI data including per-console SMI decryption keys.

Usage

1) Download and install mincg.vpk on the console.
2) Open mincg and press [CROSS] to dump the SMI data.
3) Copy the _SMI_ files from ux0:data/ to your PC
	- Please consider sending the dump to skgleba@gmail.com to help out other users.
4) Copy the [.SMI_KEY] file to the mincg/pctool/ directory
	- Rename it to something short, i.e "cur.key".
5) Run the mincg pc tool with the key-file name as the argument
	- i.e "./mincg cur.key".
6) If there is a match - congrats, you are lucky (there are only 3/256 chances)
	- If your own, previously contributed SMI got a match, you can remove or rename it from the /keys/ directory and re-run the tool.
7) Copy the "TSMI.SMI" file from /mincg/ to ux0:data/ on Playstation Vita/TV
8) Open mincg and press [CIRCLE] to flash the new SMI data.
	- If it fails, please send me "ux0:data/mincg.log" and your _SMI_ files
9) Thats it! You just changed your minfw version.

Notes

- You do it at your own risk, i take no responsability for whatever happens to your console.
- The PC tool requires OpenSSL (enc).
- mincg creates a log in "ux0:data/mincg.log".
- You should NOT downgrade below 3.60 there may be some hardware differences on lower firmwares i.e: no slims support on 2.00.
- You should NOT update to 3.74+ when it gets released, sony may patch this exploit.
