Debrick TP-Link RE350v1

Installing and Using OpenWrt

Hi All, I have a TPLink-Re350v1. After accidentally flashing the factory image instead of sysupgrade via LUCI, the device became dead. The device only flashes blue once instead of the symptoms like this Debrick TP-Link RE650 v1 using Raspberry Pi

I tried to connect a TTL to a USB cable. I measured the voltage between TX/GND and RX/GND, which were both 3.3V. However, no matter what bitrates I picked, there was nothing shown on putty. I need some help.. Is it possible that the bootloader is corrupted?

Tx should fluctuate during boot, unless it's completely bricked, or TP-Link killed serial on purpose.
