Afoundry AF-EW1200 Bricked HELP Please

[Radiotech]

Hi Hopping someone could lend a hand on this router I have it's an Afoundry AF-EW1200 which the manufacture have no longer supports, but lucky enough OpenWrt doe support it so the first firmware I flashed was 21.02.0 with no problems then up to 21.02.3 which still went without a hitch, then to 22.03.3 and deserter struck, all I have now is the power LED on and a slow flash ( 7to 10 seconds) on any of the LAN LED’s depending on which LAN port the computer is plugged into, windows reports identifying network than network cable unplugged (this also happens with a static IP address in windows) I’ve tried all the usual holding down the reset button before switching on hopping to find some kind of recovery mode, so I slid the cover off and connected a TTL (3.3V) Serial adapter and I have PuTTY on the computer (I'm not really into SSH) but I found on the internet to use a speed of 115200 but all I got was a continues roll of letters so I tried 57600 and I got this:

If I chose any option 1 to 9 the LAN LED will stay on, now that’s where I'm stuck what to choose and also how to upload the original factory firmware, from a USB drive plugged into the router or upload it from the computer using something like TFTPD64 any help would be really appreciated.

Please choose the operation:
1: Load system code to SDRAM via TFTP.
2: Load system code then write to Flash via TFTP.
3: Boot system code via Flash (default).
4: Entr boot command line interface.

Someone started to help me on another forum but gave up.
This was the instructions.

Connect an ethernet cable between your router LAN port 1 and PC
Set the IP on your PC to static 10.10.10.3, subnet 255.255.255.0
On your PC start TFTPD64 (server), copy the firmware to the same directory as the program. Name it openwrt.bin.
Power on the router with the serial console. Press "1" to use option 1: Load system code to SDRAM via TFTP.
Input device IP (10.10.10.123) ==: 10.10.10.123 (Router)
Input server IP (10.10.10.3) ==:10.10.10.3 (PC)
Input Linux Kernel filename () ==:openwrt.bin

This is the result:

The Files that are being used is:
openwrt-22.03.3-ramips-mt7621-afoundry_ew1200-squashfs-sysupgrade (I original flashed which killed it. and
openwrt-21.02.3-ramips-mt7621-afoundry_ew1200-initramfs-kernel (the file renamed and used in option 1
Has anyone got any idea how I can get this router working because I use it in AP mode connected to my Flint to extend the range in the house.
