S1300 Brick :(

Hello friends, I have a GL S1300, silly I tried to update the software version by UBoot, but I was not careful and installed a version for the B1300.
In short, I lost the Uboot interface, no LED lights up, I don’t have access to anything on the router.
The question is, can I get it back?
I have a CH341A programmer, but I also have little idea that I should flash.

Can you check some post on the forum like this one
