Unable to upgrade to GL-AP1300 3.203

Hi,
I have a GL-AP1300 in version 3.105. I can’t upgrade to 3.203.
If I try automatically or by importing the img file, the problem is the same:
The update bar reaches 100%, the router restarts…but remains in 3.105. I have no error, but the router remains in 3.105

Did you try a different browser?
I upgraded a GL-MT1300 today and had to use a different browser than whichever I started with to get it to work. Can’t remember which I started with or which I changed to but it worked fine with the second browser. The first browser just hung on the update page.

Did you install adguard home? If yes then this may be a problem. Pls uninsall adguard home and try again.

Alternatively, you can upgrade manually. SSH to the router and do the following

Upgrade with config reserved

cd /tmp
wget https://fw.gl-inet.com/firmware/ap1300/release/qsdk-ap1300-3.203-0701.img
sysupgrade -c qsdk-ap1300-3.203-0701.img

If the above failed, upgrade without config reserved

cd /tmp
wget https://fw.gl-inet.com/firmware/ap1300/release/qsdk-ap1300-3.203-0701.img
sysupgrade -n qsdk-ap1300-3.203-0701.img
