a few weeks ago i flashed my ar750ext using the web page to version 4.3.7 and after upgrading it to 3.216 it did work.
Today I connected the router again and after connecting the ethernet cable, powercable, there was no connection to the router.
I disconnected router, pushed reset button while powering on, 5G flashes 5 times and I let go.
Then the 2G LED went on but still no ethernet connection.
I tried several times but no luck.
Then I followed the unbrick manual and after awhile I got on the 192.168.1.1 Unet FW page. I selected 4.3.7 and got UPDATE FAILED. Then I tried 3.216 and got the same error.
What posibillities do I have to recover this device?
I tried uboot debrick also failed.
You can use the admin panel to do sysupgrade or downgrade.
The fist step is:
When system is fully booted, press more 10 seconds to Reset Firmware.
Hello, may I ask which interface you used to update the firmware in the link https://docs.gl-inet.com/router/en/3/tutorials/debrick/,
192.168.1.1 or 192.168.1.1/uboot.html?
In addition, there are two firmware options in the interface 192.168.1.1, and the firmware downloaded from the download site https://dl.gl-inet.com/?model=ar750 ends with bin, so you need to use the firmware in the NOR flash firmware.
192.168.1.1:
thank you for your replies. After changing my W11 laptop with a Linux one, the connection remained stable and I could update/replace the firmware.
Now, after several days it remains stable on 4.3.7
