This could be due to stale TPM data. + +If your device continuously falls into recovery on reboots after rescue, boot to +an OS test image via USB through the recovery screen. Once booted in the OS test +image, issue the `crossystem clear_tpm_owner_request=1` command on the kernel +console. Reboot and allow the OS on disk to boot. -- cgit v1.2.1
