Hi Klaus,

I have been using firmware files datestamped 27/12/2020 6:14, from:

https://github.com/raspberrypi/firmware/archive/master.zip

I have used these, to replace ALL those files on the DOS partition in 
the 20201224 img.

I had assumed these were all the 'latest' versions. I just did a 'fc' of 
a file from the ZIP file, against one downloaded from your links above:

D:\RPi4b\RPI_Firmware>fc blob-master_dtb\bcm2711-rpi-4-b.dtb 
master\boot\bcm2711-rpi-4-b.dtb
Comparing files BLOB-MASTER_DTB\bcm2711-rpi-4-b.dtb and 
MASTER\BOOT\BCM2711-RPI-4-B.DTB
FC: no differences encountered

So I am reasonably confident I have indeed been using the correct latest 
versions.

I am happy to do any further testing, or checking on my tests if you 
feel they may have been in error.
