Debricking archer c7 v1.1

i am trying to debrick arhcer c7 v1.1 using tftpd method but after sending file to router showing this in log viewer

Connection received from 192.168.0.86 on port 1259 [11/09 16:18:52.484]

nothing happens router remains bricked.

So the tftp transfer completes, but the router rejects the firmware image, there are three potential reasons for this:

  • wrong image uploaded, factory, correct h/w rev.
  • wrong region code
  • the h/w ID in ubootenv got messed up

the former two you can re-check blindly and try again, the later would require serial console access to fix up (how did you brick it).

i am using official tp link firmware to debrick it.
i bricked that while downgrading from 23.05.0 rc3 to 22.03.5

generic failsafe/ firstboot and a factory reset should have sorted that..

Will you elaborate please?

but you're beyond that now.

Try debricking with the OpenWrt factory image, if that doesn't succeed you will need serial console access to the bootloader (but realistically you'd rather look at getting a cheap replacement device, especially when it comes to the h/w rev. 1).

This is mentioned in the wiki. Broken boot loader. Serial is the only way to recover.

Try a factory reset (erase any configuration / added packages / etc.) so it is just the firmware image and the defaults it loads. See: Reset Button

For an Archer C7 the reset button is a small, recessed button on the back that can be depressed with a paper clip.
