I have a GL-iNet AR750S Slate. I didn’t use it for a period but now it came its time.
First thing was to try and update its firmware. Last firmware is 3.104, compiled time: 2020-04-27.
Well… at “Online upgrade” section there is a line where the available pdate is 3.201. I hit Download and after a few seconds I get “Verification Result: Fail”.
I said “let’s try Local Upgrade”… downloaded the firmware from https://dl.gl-inet.com/firmware/ar750s/release/ and after I upload the file I get “Failed! ERROR: Incorrect firmware format!”
