Following these instructions (Debrick via Uboot - GL.iNet Docs 3), I need to download a .bin file to get the firmware for my AR750S and then upload it via the U-boot web interface. But GL.iNet download center contains only .img files that cannot be uploaded via U-boot. How do I debrick without a .bin file?
When I look for firmware for the AR750, I see .bin files so this appears to only be an issue for the AR750S.
Thanks in advance.
Please read this manual carefully. To debrick a AR750s via U-boot you have to download the .img firmware file and upload to the NAND flash.
My U-boot interface at 192.168.1.1 does not have this option:
.How do I upload the .img to the NAND flash?
Yes, you are right, the menu looks a little different, but you dont’t need a bin file. With an img file you can easy debrick your AR570S via U-boot. I have just checked with my Slate. It works. With last firmware 3.105 I had an error, but with 3.100 it was without problems.
Sorry I am missing something. Are you saying I should use the U-boot web interface at 192.168.1.1? When I try to upload the .img file I get an error that says it is too large. Can you be specific please what you used to upload the 3.100 .img file to the AR750S device?
I used U-boot to flash a router with an img firmware.
My U-Boot menu on my Slate looks like this.
Try with firmware 3.100. It worked for me. With last firmware 3.105 I had a Problem during flashing.
By the way, you can fine a .bin file for the AR750S following this link
https://dl.gl-inet.com/firmware/snapshots/3.105_beta2/ar750sm16/
This is a last beta firmware. Before you try it please contact technical support from Gl.Inet
I am not sure it is not damage your device:)
Thank you so much 3.100 worked so I am back in business and this particular thread is resolved.
Question: do you know how I can update to OpenWRT 19.07 or later?
Thanks,
Peter
If you don’t need Gl.Inet interface and you have skills with luci you have to download an OpenWRT firmware for your Slate and install it via U-boot.
At the moment there is no operwrt factory firmware for AR750S for download and I’m not sure
is it possible to do a sysupgrade procedure via luci with sysupgrade.bin
I personally will wait for an updated Gl.Inet Firmware.
https://firmware-selector.openwrt.org/?version=19.07.5&target=ar71xx%2Fgeneric&id=gl-ar750s
That is working for me. I loaded it via the U-Boot menu.
