Installation notes
- Already running OpenWrt or ImmortalWrt: flash the sysupgrade image from LuCI (System → Backup / Flash Firmware) or with the sysupgrade command.
- The kernel / initramfs image boots from RAM without writing to flash — useful for a first install or for recovering from a failed flash.
- Verify your download against the published checksum before flashing:
