I am on latest hekate and atmosphere (1.10.2), I accidentally updated my sysmmc to 22.0. I know, that I wont be able to boot into sysmmc right now, that is not the point for me.

However, my emummc is still on Firmware 21.0.0

When I try to launch emummc, I get this message: "failed to match warmboot with fuses. if you continue sleep mode won t work"

What can I do to boot into my emummc with Firmware 21? The latest hekate and atmosphere should still be compatible with that.

Just as it says sleep mode won't work, just going have to wait until Hekate get updated.

Can I do anything to boot into emummc with firmware 21 without this message?

When going to standby, my switch totally hangs up.
