Ive tried normal boot.
Frozen 1 red 1 blue light.

Ive tried reset button , power on , 25 second hold reset.
Frozen 1 red 1 blue light.

I then researched what the nexq6go is, and found this
https://openwrt.org/toh/zbtlink/we-826

I tried the first option, power on, then reset for 15 , same results.

Im currently acquiring all my tools to try the second method, accessing the serial port on the board , to try to replace the bootloader.

I am familiar with PIC and microchip products, so i know how bootloaders work, ive written some. I am pretty sure I used the wrong option in the chinese bootloader, to load my firmware backup, and like a dum dum went and overwrote the bootloader cause it didnt want the backup , but the actual firmware to work right.

This should mean my router is technically ok, but i need to replace the bootloader, to service it again. And the serial port I see on the board should provide for that.

Any guidance so i can get this fixed?

I would connect to the uart/serial pins over usb and see what the serial terminal shows is going on. It might have a failsafe tftpd server/client flash recovery.

I've honestly never done it on this router. Not much help. :(

Proper bricked it. No joy on serial. need to get my hands on the bootloader and manually load the chip. Is the booloader available?

I think I can copy pretty much anything off a live one. Let me see.

What tool are you using to flash with?
