Custom ROM flashing via Payload Dumping & Fastbootd
k2luIf you don't want to use TWRP or OrangeFox, and would prefer fastbootd, here's a different way to flash custom ROMs to your device.
* Download the Payload Dumper tool from here for your operating system
* Extract the ROM zip file
* Dump the payload via CMD/Powershell/Terminal etc.
- for *nix: ./payload-dumper-go payload.bin
- for Windows: payload-dumper-go.exe payload.bin
* Go into the directory with the extracted images
* Boot your device into fastbootd
* Flash the images to the required partitions
* Format data (preferably through fastboot with fastboot -w)
* Reboot
