GL-S1300 personal firmware issue

Hello, I have two GL-S1300 devices. After flashing the firmware via the page (, I found that the devices cannot boot up. There are no LEDs lit, no network connectivity, and the reset button doesn’t work either. Could you please advise on how to restore the devices to working condition?

I have to try use reset button ,It doesn’t work and can’t access the U-Boot page.I also tried using TTL with a baud rate of 115200 to retrieve the boot information, but it still didn’t work.

Please refer to this:
