I tring to connect console, and find 5 pins try out 3 pin for Tx Rx and GND.
But here are some problem happend.
Using 115200 8N1,I got correct output but always send wrong input.
For example I press "1" the console will get "1g" or "2" get "23"(and enterkey) and arrow, enter key will not work.
Enable local echo for checking my KB not broken, connect RPi console checking my dongle run well.
Trying every baud rate or other option be sure in the right config.
I using Winddow Putty, Linux screen,minicom but get the same result.
What's problem about this situation?
I just want to install OpenWRT onto E7350
I am wondering if we need to move this discussion to the "for developers" area for better exposure? There is a older thread for this model in that area already but it closed in September. Maybe that could be reopened instead of starting a new one?
I see the hint in this thread said "New replies are no longer allowed." I thinkg I can't reopen that thread
I will get a try, but in console show that firmware will verify GPG sign,and the public key store in the runing firmware (or online URL) not uploading firmware file.
There is my secend problem,the console not works well.
Get the right output but wrong input,I can't choose the option I want in U-Boot menu as I mention at first post.
Cool. I have a different 3.3v usb serial adapter so a diagram where to connect the Rx, Tx, and Gnd will work. I am holding on a bit though to see if there is another workaround rather than having to open up the unit.
This is the usb-serial adapter cable that I have:link. It comes with a Tx, Rx, and Gnd connector which connect to the serial header on the router circuit board. Hopefully the router serial header is populated?
so installing factory.bin via web interface does not work, tried both available rt1800 firmware.

My RT1800 arrived with "Current firmware version: 1.0.00.005"
Updated it with FW_RT1800_V1.1.00.016_Prod_20210723_code.bin
Web interface showed "Firmware Version 1.1.00 build 16 Jul 23, 2021"
Then upgraded it with -factory.bin first, then finally with -sysupgrade.bin (built with Luci) using scp/ssh.
