How it works

It downloads
- Ubiquiti EdgeOS 2.0.6 stock firmware with new bootloader e51_002_4c817
- OpenWrt 18.06-snapshot-r7911 initramfs factory with small enough kernel for flashing through EdgeOS
- OpenWrt 21.02.1 sysupgrade image
Ensures that only one firmware image is stored on device
Installs EdgeOS 2.0.6
Checks bootloader version and upgrades to boodloader that enables TFTP recovery in case something goes wrong

- boot md5sum : 91ac6bc5084f78bc3f8cabd859460c0f
