is there a workaround without perl?

You could replace the byte with a hex editor, EPiC-APOC, but I'm not even sure this is a valid solution. I still don't get mpeg2 or vc1 enabled. shrug

BTW, "sudo -s" is usually the way to get a root shell. (but is also frowned upon. just prepend sudo to your three lines of code. ;-)

Mount SD on Linux , i used a virtual machine with an Ubuntu dist and used perl there.

Last version this works on is Apr-15-2020:
https://github.com/raspberrypi/firmware/tree/9e3c23ce779e8cf44c33d6a25bba249319207f68/boot

The latest files all show the following after the 47E933363248 string:

start.elf: 0918
start_x.elf: has two locations, 0090 and 1D18

Hopefully someone smarter than me will be able to make it work.
