GL iNet-AR300m16-EXT Flash Problem

I have the above unit and downloaded the software.   When flashing to AREDN Firmware from stock, using the Update procedures, I get the following error "Failed! ERROR: Incorrect firmware format!"

Tried on two different machines, using Stable and Nightly builds.  Any one have a clue how to proceed??  The model appears to be supported, best I can tell.

GL iNet-AR300m16-EXT Flash Problem


To be sure, please post the exact .bin file you are uploading and that the md5 checksum matches.

I have an AR300M16-EXT and have loaded and and nearly every Nightly Build inbetween.


So I obviously do not know
So I obviously do not know haw to complete the initial flash.  Could the error be from the sha256sum data.  How is the Chksum used and what is the file the flash is looking for?

The on-line information leads me to believe all I have to do is download the sysupgrade.bin file, go to Update, select the downloaded file and do Update.  That's where things come apart.  I feel like a step was left out.

The file I am trying to upload is:  aredn-317-232d7bf-ar71xx-gl-ar300m-sysupgrade.bin

sha256sums is

GL iNet-AR300m16-EXT Flash Problem

The file I am trying to upload is: aredn-317-232d7bf-ar71xx-gl-ar300m-sysupgrade.bin

That is a valid file for the AR300M16.
The checksum is used to ensure that your downloaded files is an exact copy of the aredn-317-232d7bf-ar71xx-gl-ar300m-sysupgrade.bin
The (ensurance) action taken is to run a checksum program on your downloaded file.
The md5sum program will return a value.
I ran md5sum on my downloaded copy:
md5sum aredn-317-232d7bf-ar71xx-gl-ar300m-sysupgrade.bin
3af52b0731716544d8daafec41ed6476  aredn-317-232d7bf-ar71xx-gl-ar300m-sysupgrade.bin

The on-line information leads me to believe all I have to do is download the sysupgrade.bin file, go to Update, select the downloaded file and do Update. That's where things come apart. I feel like a step was left out.

The on-line information
Be sure to uncheck the Keep Settings checkbox
, since GL.iNet settings are incompatible with AREDN® firmware.

You omitted this step in your post.

I hope this helps,

The option to uncheck the box
The option to uncheck the box is never presented to me.  I know about the check box but have no opportunity to uncheck it.  I have flashed the iNet devices before and have seen that box

I am also familiar with the purpose of the chksum, but grasping at straws I thought maybe the firmware flash was somehow checking it.  Never had any flash before doit but again, somethings amuck.  I flash router firmware all the time..  I have tried on 2 Windows machines and a Mac with the same results andbaffled.

Uncheck 'Keep settings'

Hi, jb:

 I am baffled too.
Withing the last few months, I purchased and loaded AREDN firmware on a GL-iNET-AR750 (Creta),
but I have no recollection of when or where I may have seen an 'uncheck settings' box.
I have GL-iNet devices USB150, AR150, AR300M16-EXT. AR750 (Creta), and MT-300N-V2 (Melon).
The MT-300N (not supported by AREDN) has the GL-iNET firmware.
The GL-iNET-MT-300N-V2's 'Advanced' -> 'System' -> 'Backup / Flash Firmware' page has a 'Keep settings' box.
...attaching images...
I hope this helps,

I am concluding that the latest GL-AR300M16 routers do not allow non-GL firmware to be flashed.  The AREDN img must not be compatible with the new boxes.  I really am "bummed out" since I wanted ot get some experience with AREDN.  

Maybe I can swap it for a TP-Link device.
