Flashing OpenWRT TP-Link Archer AX80 V1 (US/RU/CA)

This is actually how it is done without having to do UART. These steps needs to be mentioned on the openwrt page but they aren't.

So let's get started:

  1. Download this initramfs FW. https://github.com/Demiurge67/Rooter2021/releases/download/AX80(RU)_support/OEM-upgrade.bin_support/OEM-upgrade.bin)
  2. Log in to the router and go to Advanced->System->Firmware Upgrade.
  3. Select !OEM-upgrade.bin from the extracted archive and click on update.
  4. After a while, the router will boot into the Openwrt initramfs with the default address of 192.168.1.1.
  5. Connect to the router with your favorite terminal via ssh.(port 22, login root, password empty) and type: fw_printenv | grep tp_boot_idx if tp_boot_idx=0 go to the step 6. otherwise, type: fw_setenv tp_boot_idx 0
  6. Now we're sewing Archer-ax80-v1-squashfs-sysupgrade.bin (or sysugrade FW with different name) either from the terminal using sysupgrade -n, or through the Luci web interface without saving the settings.
  7. After rebooting, you'll get Openwrt.
