GL-AR300M16-EXT stuck in uboot

Solved my own problem in the end. Not sure whether all of the steps are necessary, but sharing below.

  1. Use Firefox. Using Safari 15.6.1 on macOS was not working.
  2. Disable NAND/NOR switch. I don’t remember enabling it, but disabling it seemed to help.
  3. Flash the basic OpenWRT AR300M NOR firmware: https://downloads.openwrt.org/releases/22.03.0/targets/ath79/nand/openwrt-22.03.0-ath79-nand-glinet_gl-ar300m-nor-initramfs-kernel.bin
  4. Once that boots, use the OpenWRT firmware upgrade page to upgrade to the current AR300M16 firmware from GL iNet.
