TP-Link RE450 v3 bricked

Hey there
I installed openWrt on my RE450, I noticed it didn't have an gui, so I wanted to return to the stock firmware.
I tried to return to the stock firmware the normal way from the commandline but I did something wrong and now all the leds are flashing and the device is powering on and off. Does someone know how I can debrick it?

Is the only way with a serial connection? and does someone have a guide on how to do that?

Did you already tried failsafe mode ?

See https://openwrt.org/docs/guide-user/troubleshooting/failsafe_and_factory_reset

Follow entering failsafe modus and factory reset, soft or hardware factory reset.

All the best, samoth

This might help down the road
