Ebay R710 cannot connect via SSH or browser. NMAP reveals several ports open after factory reset

john_sutherland — Wed, 14 Oct 2020 05:23:00 GMT

Just received used R710 from ebay auction. Plugged in to 12v power, factory reset, tried the phone app to try Typical Install, get the "Great you are connected to Unleased factory WiFi...." but when I hit start I get Unleashed Unable to fetch default configuration from the AP. So I try connecting via wire to 192.168.0.1, nothing, not SSH not HTTP or HTTPS. Nmap reveals:

Discovered open port 53/tcp on 192.168.0.1
Discovered open port 9999/tcp on 192.168.0.1
Discovered open port 18301/tcp on 192.168.0.1
Discovered open port 1883/tcp on 192.168.0.1
Discovered open port 8099/tcp on 192.168.0.1

So, is there anyway to fix this? Can I put Standalone or fresh version of Unleashed on it using the USB port? Can you upgrade the firmware using the USB?

Thanks in advance for your help,

John

Hi John,

I think we have already discussed this issue on another thread.

Sorry John, like so many before you, you've been sold an unsupported AP, and likely something that was bricked and damaged. I would submit to get your money back.
Also, on your NMAP, try using the -A switch. you'll likely find nothing 'listening' on those ports.

I had the same issue. Solved by flashing a new firmware via tftp and connecting the onboard spi-pins.

@jside Could you share some info about the pinout and connection settings?

Did you use a standard serial cable or something like an Arduino TTL serial cable or what??

I used a cable similar to this one: https://lawicel-shop.se/elektronik/kommunikation/rs232/usb-to-ttl-33v-serial-cable-for-rpi/

But basically any 3.3V serial to usb cable would work.

Using mincom in linux to connect 115200 8N1

Pinout something similar to:

(Not my picture, borrowed on internet)

You need to setup a tftp server. I used my laptop with the same ip range as the AccessPoint, and had a tftp server running locally on it.

Then you can flash by:

fw set host <TFTP server IP address>
fw set proto tftp
fw set port 69
fw set control <image file name>
fw update
reboot

image file name is the firmware you want to flash onto the ap, which should be located on your tftp.

@jside Thanks very much, I will give this a shot tomorrow.
