Hey guys,

I have followed this guide posted here, http://ediy.com.my/blog/item/78-recover … s-n-router
And I have finally unbricked my MR3020. Sort of.

I used TFTP via USBART to save it. I flashed via these steps.

hornet> setenv ipaddr 192.168.1.1
hornet> setenv serverip 192.168.1.100
hornet> tftpboot 0x80000000 openwrt-ar71xx-generic-tl-mr3020-v1-squashfs-factory.bin
hornet> erase 0x9f020000 +0x3c0000
hornet> cp.b 0x80000000 0x9f020000 0x3c0000
hornet> bootm 9f020000

I still running into some issues. The router boots and goes into a "eth0 entered forwarding state".

However when I try to access 192.168.1.1 via my web browser it fails to connect or go anywhere.
It says connection failed or something along the lines.

Is there something I need to do? For those who have properly made Shairport work please advise!


Thanks!!!

You have flashed a snapshot image, which comes without LuCI.
Since the MR3020 has only 4MB flash, you will not be able to install LuCI now.
Use SSH instead.

How do I flash sys_upgrade via SSH or TFTP?

Copy image to /tmp

Then in ssh

sysupgrade /tmp/'your_image'

got into the first boot. was doing everything wrong, should have set the device on 192.168.1.2.
Then telnet into the device and change passwd.
Then access it via web browser via 192.168.1.1.

Then flashed the sysupgrade.bin, everything works fine with the router now...

Now how to get shairport working.... hmmm...

Any idea why I only get internet from IPV6 and not IPV4?
Am I setting something up wrong? Thanks!
I cannot get an ip address from ipv4 but ipv6 routes directly to the main router where I get internet from.

What are the contents of /etc/config/network and /etc/config/firewall?

Fixed, I had to go into the web interface and press connect on the LAN setting.

Now ipv4 works also.

The discussion might have continued from here.
