I bought a mr-3020 but this was not working. I was able to get connection via serial port, an have a look with "screen" on the router. When i press "f" and enter at the right moment, I get into the failsafe mode, but I can't get connection via LAN. I can ping it on 169.254.171.194 but get no conection via telnet or ssh. How can I get a SW on it to flash it new?
But the connection with TFTP should work over LAN or? I Think I don't get connection over LAN.
And who to start this TFTP. In the instruction says "type in tpl, when Autobooting in 1 seconds" is to see.
But I don't see this, because, there ist not the OEM SW on it.
The output for TFTP instruction in the Wiki comes from the serial console.
Assuming you serial cable works intended, you should be able to interrupt the
boot loader, and reflash the unit using TFTP.
The loader kicks in before the OS, in our case OpenWRT.
You need a physical network connection to transfer the image, but there's no
relation to the unit being unreachable once OpenWRT's booted.
But it was not possible to type in tpl. So I testet something different. I bootet again, with´the WPS-Button pushed, and then it should be possible to get a file via ftfp
Hello
I had success. When You know how it works, it is quite easy.
What I did:
-connect the Router via a switch with a Windows Computer
-installed tftpd64 as portable version
-set computer IP at 192.168.0.66 (sub 255.255.255.0)
-rename the SW (openwrt 17.01) to „mr3020v1_tp_recovery.bin“ and put in the same folder like tftpd64.exe
-open tftpd64, check the path, set the correct ip
-push/hold the WPS button on the router and plug it in
-lay back and look on screen how it works, it reebots itself and then the router accessible on the ip 192.168.1.1
The serial connection is not necessary for this, but interessting to look at.
