Mi 3 router boot mód váltás

Sziasztok!
Egy Xiaomi Mi WiFi R3 routert próbálok helyreállítani, de elakadtam a boot mód váltásnál. Nekem az egyes opció kellene.(  1: Load system code to SDRAM via TFTP.)

Próbáltam nyomogatni a reset gombot indításnál, de nem vált át. Hogyan tudom átváltani?

Please choose the operation:
   1: Load system code to SDRAM via TFTP.
   2: Load system code then write to Flash via TFTP.
   3: Boot system code via Flash (default).
   4: Entr boot command line interface.
   9: Load Boot Loader code then write to Flash via TFTP.


3: System Boot system code via Flash.

Ha jól értem, hogy mit szeretnél, akkor az nem lehetséges:

"Writing to the console in the factory firmware is only possible during first boot; afterwards it is disabled by the firmware."

Tehát esetleg factory reset, aztán az első boot-nál újra próbálod az egyes opciót?

For whatever reason, I did manage to do so the following way (I have no clue why this works, I've just seen it works accidentally and continued to it the same way):

  1. Disconnect everything.
  2. Connect the dongle to the computer, and connect the router to the dongle except for the Rx wire (for whatever reason, but otherwise the router won't start with dongle connected).
  3. Connect the router to the power source, and when it starts blinking its lights, quickly connect the Rx wire and start the console as fast as possible.
  4. You'll see the option selection countdown. Press 1 while moving at the speed of light.
  5. Voila.

This is tough to perform as you have to act very quickly. The whole connecting things and pressing buttons sequence has to happen in 2-3 seconds. You can attach so buttons to the wires to make it simpler.

De lehet csak scifi. :)
