"Failed to apply 'nosigchk'" after update to HATS-2026-07-11-f4dc3b1 and contextual FW update

[GDT1978]

Hi,
I just updated to HATS-2026-07-11-f4dc3b1 and to FW 22.5.0 and now I got the error from HekatOS at startup.

"Failed to apply 'nosigchk'"
Press POWER to continue.
Press VOL to go to the menu.

If I presso POWER the switch loads to Atmosphere.

What should I do?

Delete the existing bootloader folder and re extract the new one. It should fix the issue
