Not able to boot after uploading wrong image (TP-Link Re305 v3)

Installing and Using OpenWrt
1

Dear Community,

During firmware update, I've installed wrong version and now my extender (TP-Link Re305 v3) is not booting, it is restarting while red LED is blinking. I connected via serial interfaces and following is the output of my serial. BTW, ethernet is not working, my laptop doesn't recognize that it is connect.

Even though I connected with serial, I'm not able to select a boot option, it is always going to 3 as default.

This is repeatedly printing. I'm not able to select other options to install new firmware. I'll be appreciated if you can help me to fix the issue.

What file and how you uploaded?

It was months ago, I forgot those details, I recently got the serial setup and wanted to try with serial, but apart from viewing the logs I cannot do anything:(

Have you tried option 1 or 2? For option 1, you'd use the kernel image. Option 2 would use the factory image.

Alternatively, you could attempt to install the vendor firmware again via option 2.

Iā€™m not able to select other options:(

It instantly continue after printing options. Even I cannot select any options:(

Is there any other way to stop at options and wait my response? Or any automated firmware uploaded which uploaded using the serial, since Ethernet is not getting connected?
