We recommend Freifunk-Communities to link to the following documentation instead of publishing their own Instructions to avoid fragmentation of useful Information. It does not contain Community-specific quirks.
Download the needed images for your device and put them beside this script.
Remember to eventually turn of NetworkManager or place a dumb switch in between so that the link stays up during repowering the FritzBox. For the 7520 I had good experience plugging the device in, waiting until all LEDs are lit during boot, and start the script directly after this.
Using network autoconfiguration with privileges (uboot images must be in the same folder too):
wget https://downloads.openwrt.org/snapshots/targets/ipq40xx/generic/openwrt-ipq40xx-generic-avm_fritzbox-7530-initramfs-uImage.itb
wget $GLUON_URL_avm-fritz-box-7530-sysupgrade.bin
wget https://downloads.openwrt.org/snapshots/targets/ipq40xx/generic/u-boot-fritz7530/uboot-fritz7530.bin
sudo python3 fritzflash.py --dev eno2 --initramfs ./openwrt-ipq40xx-generic-avm_fritzbox-7530-initramfs-uImage.itb --sysupgrade ./gluon-ffac-v2022.1.14-1-avm-fritz-box-7530-sysupgrade.bin

Using self configuration for other devices:
wget https://downloads.openwrt.org/releases/22.03.5/targets/ipq40xx/generic/openwrt-22.03.5-ipq40xx-generic-avm_fritzbox-4040-squashfs-eva.bin
wget https://downloads.openwrt.org/releases/22.03.5/targets/ipq40xx/generic/openwrt-22.03.5-ipq40xx-generic-avm_fritzbox-4040-squashfs-sysupgrade.bin
sudo ip a a 192.168.178.2/24 dev eno2
./fritzflash.py --dev eno2 --sysupgrade ./openwrt-22.03.5-ipq40xx-generic-avm_fritzbox-4040-squashfs-sysupgrade.bin
Make sure to replace eno2 with the correct name of your ethernet adapter

- disable Wifi
- allow incoming port 69/UDP or disable Firewall
- run script as administrator, so that it can change the current ip address and open Port 69/UDP
- enable Firewall
- enable Wifi again
For other devices than the 7520/7530/1200, less privileges are needed (no TFTP) if the initial ip address is set manually in the network adapter configs.
