How does it work? - Check out Moth Exploit by TeamMolecule/xyz: https://wiki.henkaku.xyz/vita/Vulnerabilities#moth_exploit
This tool lets you find a compatible signed SMI block for your console.
This tool lets you Flash/Dump the SMI data including per-console SMI decryption keys.
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 firstname.lastname@example.org 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.
- 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.
