This is related to Odroid C2 on 11.0.1: switching tv to 24fps? where I was trying to get my C2 switch to 1080p24, even though it is not normally detected by EDID? Followed the Intel-related instructions in https://wiki.libreelec.tv/configuration/edid#intel however during boot the boot process is stopped with the error message specified in the subject and described in length in my older thread.
Has anyone on C2 been able to successfully use these instructions, in order to boot with a modified EDID file? If not, then there's obviously something different on C2 boots, otherwise I'll need some help figuring what I'm doing differently here...
