Device died after updating u-boot

Hi,

I got my Opal brick when updating firmware recently.
I was following tutorial to debrike via uboot, updated uboot at http://192.168.1.1/uboot.html, waited for a few minutes, cannot be sure it reboots or not (SSID already disappeared since it brick) so I powered off the device.
Now its light died completely when I power it on, the device seems still can communicate with my PC but I cannot access 192.168.1.1 or 192.168.8.1
Is there anything I can try to save it?

It sounds like there is a problem with the installed firmware file.

The update via Uboot does not require a manual power failure. After uploading the firmware, you just need to change the PC’s connection back to DHCP and wait for 192.168.8.1 to become available.

It seems that you uploaded the file in the wrong part of Uboot.

http://192.168.1.1 is to upload firmware to debrick the router or update the firmware

http://192.168.1.1/uboot.html is to update the uboot itself. You can upload whatever you want there, so you must be extremely careful

So please check if you entered the right URL

I uploaded the bin downloaded from uboot-for-qca95xx/bin at master · gl-inet/uboot-for-qca95xx · GitHub to update uboot.
Anyway the device is dead already, nothing I can do now I guess?
