I just purchased 3 GL-iNet mini smart routers "shadow", model GLL-AR300M16-Ext. and I cannot seem to get the ARDEN firmware to take.
When I upload aredn-20250928-dadf66e3-ath79-nand-glinet_gl-ar300m-nand-squashfs-sysupgrade.bin the router accepts the firmware with warning, displays the keep settings slider, and presents the "install" button. I press install, router reboots back to GL-iNET firmware.
