Post was complete, I waited 10 minutes and never showed anything but what I wrote above, then I tried to start with the reset button pressed, the only difference was that I showed at one time message that is waiting to release reset button, then continued as in the post above, here is the complete log that appeared when I started with the reset button pressed and then I released seeing the message that is waiting to release the reset button

I DID IT !!!
Very Happy
Boot sequence stops with the command Ctrl + C, at which the router begins to respond to ping. I then tried to use a TFTP server to upload the firmware but it did not work. Trying to access the web interface I had the pleasant surprise to see that there is an interface that allows me to upload firmware directly from there. Thanks to all who participated with ideas and tips

I come back with a mini tutorial for this model in the hope that it will be useful to anyone else. Thanks to all who participated with ideas and tips


YEAH !
Please upload image of soldering work. Thanks !

TP1 = to the Rx port of the serial
TP2 = to the Tx port of the serial

U can use a normal serial conection, no need for level adapter from 3,3v to 5 v

to stop the boot proces use Cntrl+C command , after acces emergency boot room via web on 192.168.1.1 (broadcom mini web server)

maybe there is a way to stop boot process without using serial connection. I mean some procedure with qss/reset button ?

what did you use to connect metal parts to pcb ?

I used solder soldering. I tried all sorts of combinations with the reset button, but no effect.

I asked you because the pcb looks burnt and there is a connection between TX and RX - that looks for me

I used something besides solder, rosin, to prevent solder to join the two points that are very close. because of rosin the PCB looks like it is burned

The circuit can be easily destroyed if you use a soldering iron that has too much power; is preferable one as small power as possible, or if you have a hot air soldering station, and work carefully as rapidly possible, avoiding to keep the soldering on the circuit too much. Also need to use solder that melts at a lower temperature and to be as thin as possible.

What kind of soldering iron did you use ? How many watts ?

Hi, please, could you tell mi which pin should I use for GND, is it one of TPx pins? or e.g. could I use GND from wifi antenna?
I have W316R and I upgraded with wrong fw, I hope there is a chance to upload correct fw. I wrote to tech support and they told me that the router is totally damaged.
Thanks in advance for help.
