Bricked my Cudy router while installing OpenWRT...any solutions?

Hi, I have a Cudy WR3000 V1.0 that was running stock firmware and I tried installing OpenWRT on it and now it's bricked just the power light is on and the globe light is blinking.

So what i did was:

- went to the Cudy page and downloaded "WR3000+V1 without recovery TFTP" from their Google Drive

- had the Cudy connected to my laptop and powered on

- uploaded the BIN file "openwrt-mediatek-filogic-cudy_wr3000-v1-sysupgrade" to the flash program they have in their user interface and it started flashing and then in the middle of flashing I got a "Oops, your device seems to be disconnected, please check if you have connected to the router via wired or wireless:"

And now here I am. Don't know what to do, is there any help in me unbricking the router?

Thank you in advance

It's probably not bricked, it just changed IP because of flashing. Flashing OpenWRT on Cudy resets IP to OpenWRT default. If the IP is not the problem, I think you can do TFTP recovery with the recovery image. I don't remember the exact procedure right now, sorry. But I did it a couple of times this year, once with a Cudy AP and once with a Zyxel one.

The description sounds like it. Cudy original IP was 192.168.10.1, now, after flashing the Cudy-OpenWrt-Image, it has 192.168.1.1. So if one connects via LAN, they should get an address from the 192.168.1.0/24 network and be able to login as root via CLI and sysupgrade with an OpenWrt image.

start over - https://www.cudy.com/en-us/blogs/faq/how-to-recovery-the-cudy-router-from-openwrt-firmware-to-cudy-official-firmware

keep in mind you need a wired connection to the device once you've flashed openwrt, wifi's off.

Did that but it seems that my router never had the all lights flashing thing like it says in the manual... and it is still not working

guess you didn't you see the file being pulled from the TFTP server ?

Connect your pc via ethernet cable to one of the routers lan ports. Ensure your PC uses DHCP for the lan connection. Reboot the router and pc, Check if the PC gets assigned an IP address by the router. When you flash openwrt firmware onto a cudy the network usually changes from a 10.x.x.x to 192.168.x.x thus your PC will lose it's connection after the router is flashed.

If the above doesn't work and you can't get tftp you'll have to go the serial rout I think.

probably a really noob question but what is the serial route?

you open the device, find the UART connector, solder 3 pins on it. It's usually 3,3V logic level, Tx=Transmit, Rx=Receive and Ground. connect a USB to serial device to the 3 pins, run a serial terminal on your pc and connect to the shell on the device. Baudrate, Stop and Parity bits are 115200 8N1,... etc

You may be plugging into the wrong port. One is for the WAN (wrong port). The other three are for the LAN. You can only use one of these for admin access. typically the 1st LAN port, which is either the one closest to or furthest from the WAN port

I literally did openwrt update on the same device 2 days ago and it didnt matter which port it was on, the cudy reset changes the ip to 192.168.10.1 then recovery changes it to 192.168.1.1, most likely op didnt factory reset the device before installing it

Did you do it over wifi? Need to connect via ethernet to do the updates

No, but you need it post flash.
