Hi,
Since some people seems to wait for a safer downgrader, i did one in a few hours. This is a fork of sysupdater, with a few things added which should prevent some errors (wrong region downgrade pack, corrupted downloads...) :
- automatically load update information (needed files, md5) based on your 3ds model and region
- md5 check all the cia update files before downgrading
- can check your update files without actually downgrading
To use it you have to :
- Put SafeSysUpdater.3dsx somewhere you can launch it...
- Put your downgrade pack as usual ("/updates/*.cia")
- Launch it multiple times until it pass the black screen (hax)...
- Pray
Notes:
- If it freeze just after you press (Y) to downgrade or "init ->" more than 1 second, restart..
- The 9.2 JPN package is in fact a 9.1 package, no problem with this..
Changes :
- v1.0: add new hax for FW > 10.3
- v1.0: downgrade browser and homemenu last (but before native_firm)
- v1.0: few bug fix and improvements
- v09: add downgrade logs ("/SafeSys.log")
- v09: only md5 check downgraded files
- v09: remove sysupdater dependency
- v08: fix JPN files path..
- v07: finally fixed the input freeze... by removing this second confirmation screen.
- v06: try to fix input freeze... again
- v05: minor input fix
- v04: added japan support (with bad title skipping)
- v03: big improvement in hax success rate
- v02: Add simulation mode to check your update files without actually downgrading
- v01: Removed the config files, just put the ".3dsx" file somewhere and downgrade... and pray.
- v01: Added a CIA version to downgrade from emunand so you don't need to try hard to get the hax to succeed (so it's just for testing/reporting bugs). Testing this will ensure the MD5 for each regions/models (only o3DS/n3DS USA/EUR for now) and downgrade process is correct/working. Thanks for reports !
