 |
I got my hands on a whitebox TL-WR741ND v2.4
So I wanted to flash usable firmware but something went wrong. Had RX/TX/GND connected loaded the firmware into tmp directory, wrote it to flash. Got success and reboot prompt but it bricked.
Now it´s in a boot loop. Lan port on laptop wont even light up.
Oddly enough is that now when I try to connect serial I dont get any output. So I detached TX and then I got this:

As soon as I reconnect TX to interrupt reboot, post stops and thats it. I can spam tpl however and reboot will be interrupted (LEDs stop blinking) but since I get no post obviously I cant see whats happening. with TX disconnected I cant tell the device what to do.
Hopefully someone has an idea. Thanks for any help. |
