If you didn't flashed custom (XVortex) CFE bootloader before, you may try to recover vi UART first. But, with stock Xiaomi CFE value of uart_en in nvram may be 0, so you will not have keyboard access to console, only read it's output.
Second option is short-pin of SPI on boot, in this case router will reset to it's defaults. You also need to put Xiaomi stock firmware on USB flash and recover from it with pushed reset on power on.
Third option is to unsolder and reprogram SPI on USB programmer.

I followed a guide, similar to the one on this page but for tomato, http://tomato.groov.pl/?page_id=78 i got the firmware here to install, using the webpage to send it (like i said similar to the one on this forum) so i dont know if i had installed the custom CFE.
Going to buy a cable, USB to TTL (should work?).
Perhaps could you give a bit more detail about what should i do?
Where is the SPI to try reset it?

I have the same problem and I have already tried for TTL with the same result. I really do not think I can solve it ....
