I have been trying out different firmwares to see which one suits my needs;
Official GLinet firmware 4.8.6 (OP21), 4.6.6 (OP24) and bare bone OpenWrt 23.05.5 that is written for this router.
I followed the instructions several times and I can't get to the recovery mode on the router anymore. It did work once when I first time setup the router, but now its gone. I get an error in the web browser: "Page Not Found", I tried 2 different web browsers.
These are the instructions I used. Debrick via Uboot - GL.iNet Router Docs 4
I have rebooted and reset the device several times, power cycled, reflashed the firmware several times, wiped all the settings, set it up from scratch. Still can't get to UBoot recovery.
Router does work and I can access internet via lan and via wifi.
Currently running:
OpenWrt 21.02-SNAPSHOT r15812+1076-46b6ee7ffc
Kernel Version 5.4.238
