This dump image is very very old but will bring the box up and running again. From there, you’ll have to flash the three segments again, with the informations (basically the real mac addresses) of your box.
In order to do it, you have to send a request to the gl.inet staff. They will send you the proper ART partition to flash, if you send them a picture of the label underneath the router.
I will provide you a uboot version that has been corrected, so you can upload new firmwares from the uboot GUI without bricking the router again!
Just give me a day or two…i can’t remember the uboot version without powering on my router.
