  I hope I can help with this so that the repeater image can be adjusted.
  Steps I've tested so far:
  
  #update System
  sudo apt update
  sudo apt full-upgrade
  
  # update firmware pi4 ver. 16. Jul
  # show current and latest version of bootloader : in my case (critical) current and latest 000137ad from 16 Apr 2020
  sudo rpi-eeprom-update
  
  # change FIRMWARE_RELEASE_STATUS chanel
  sudo nano /etc/default/rpi-eeprom-update # set "critical" to "stable"
  
  # shows current and latest version of bootloader : in my case (stable) current and latest 000138a1 from 16 Jul 2020
  sudo rpi-eeprom-update
  
  # rpi-update needs to change /boot partition from 96 to 256 MB
  # gparted change size /boot from 96 to 256 MB
  # i use a Debian GUI and install gparted decrease /rootfs partition and increase /boot partition
  
  #update firmware and kernel - reboot system
  sudo rpi-update
  sudo reboot
  
  #install the new bootloader - reboot system
  sudo rpi-eeprom-update -d -a
  sudo reboot
  
  #check firmware
  vcgencmd bootloader_version
  #or
  sudo rpi-eeprom-update
  
  
  At this point I tried to boot with the SD card via USB. Unfortunately, this does not work.
  The same procedure with PIOS from 2020-05-27 works without problems.
  
  Copy all the *.dat and *.elf files from the /boot (piOS) to /boot (repetier-server sd-card) -
  unfortunately, it doesn't work either.

  Will try that. Seems to be working only for a short time when i read this and that it requires recent versions.
