Hacking Downgrading to 11.3 with sysdowngrader not working?

[lisreal2401]

I'm always getting "did not find known firmware files" - CIAs are in the updates directory, I'm running A9LH Luma and don't want to use 3Down because I don't want to CTRtransfer a firmware. Does sysdowngrader just not have integrity checks for 11.3 since the last build was from last year?

I believe th only way that you can downgrade on 11.4 is if you had made a NAND backup on an earlier FW version.

sysDowngrader is/was just for 9.2 downgrades. Use the sysUpdater .cia instead: https://github.com/profi200/sysUpdater/releases
