Im trying to do an in UI upgrade from the latest supported firmware (4.5.19) to the latest 4.7 beta with keep settings on. I can upload the 4.7.x firmware (I notice it takes more time than other GL routers) and kick off the install but nothing gets upgraded and it stays at 4.5.19.
In that case, you need to reset your settings (or don't keep them).
Sometimes the upgrade process isn't compatible with custom settings and will stuck then.
If this still does not work, go using U-Boot
Resetting settings ended up working. I didn't have a complex setup though since I just got the device and set the network range and default admin password before upgrading. You may want to update your automation testing scenarios.
Which network range did you set?
192.168.28. was the range i used. I basically logged in, set up the timezone, set up the new admin password and language and then upgraded it then connected it to the Flint 2 running the op24 beta firmware.
Ran into the same issue, something to do with too much memory in use
