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:
    $ sha256sum openwrt-25.12.5-realtek-rtl839x-tplink_sg2452p-v4-squashfs-sysupgrade.bin
    edaf2b07b9a321829f1f98338e001fd7d9f3f9391abab28dd5cfa244b8ffa399  openwrt-25.12.5-realtek-rtl839x-tplink_sg2452p-v4-squashfs-sysupgrade.bin
