After update boot hangs. After grub entry selection no change of screen output. Last update on Jan 03 had been successful.
Not even success with older kernels in grub menu. I assume the update process created buggy initramfs images.
Tried Live ISO and manjaro-chroot and “mhwd-kernel -i …”, but the command seems to support uefi boot configuration only (no targets found …). My boot disk sda is still MBR style. So I restored “/” and “/boot” from fresh backup.
I hesitate to change the boot type to UEFI, including conversion of disk type from “dos” (MBR) to “gpt”.
Would have there been the possibility of choosing MBR based handling from Live ISO environment?
At least you could try to boot from your firmware the non-UEFI entry to boot the live ISO in BIOS mode. By the way, I have a BIOS/MBR triple boot system and can repair what I want with all recent Manjaro live ISO’s (not often needed though).
