I am working with an R8000 and was trying to perform the steps above to get DD-WRT (Kong or BS) into it.

I flashed OpenWRT (the second of the two files in the message a few above this one) and then rebooted the router. It pings at 192.168.1.1, but I cannot get into it. Cannot access a shell via SSH (TCP port 22 isn't responding), nor Telnet (TCP port 23 isn't responding), nor can I get to a Web interface via HTTP. Tried TFTP; it takes a few bytes of the file (whether it's the original Netgear firmware or any other) and then stops. What should I do now? I'm locked out of it.

You might try NMRPFLASH for Netgear.

Not much help for now but somebody should contact BS, as he did what seems necessary for the R8000 already for the R7000 see: https://svn.dd-wrt.com/changeset/39293

I tried unsuccessfully with the nmrpflash method, using the dd-wrt or openwrt .chk files. It was rejecting the .chk files.

I then cloned openwrt, applied the patch found here(manually)
https://bugs.openwrt.org/index.php?do=details&task_id=2009
mkchkimg.patch (2.3 KiB)

which sets the versionnumber to something high. Then I built it and could install it through the netgear webinterface without any problem.

I am having a little trouble understanding what to do with the attached file:

openwrt-bcm53xx-netgear-r8000-squashfs.chk

Do I have to flash this and then follow from instruction 12 onwards?

If so how do I flash this file?
From the R8000 directly, as with any firmware update or some other method?

Cheers.

Read it all again. Saw that was exactly what I should do Smile

Kongs latest dd-wrt build successfully installed now.

Huge thanks to all involved in getting this to work.
Most appreciated.

I made my own instructions using the ones in this thread, so credits go to the people that posted them.

Obviously ignore the parts that relate specifiably to my setup (e.g. (virgin cable modem)

1) Update netgear firmware from router gui using the file:

openwrt-bcm53xx-netgear-r8000-squashfs.chk

2) ssh into the router with Code:

ssh root@192.168.1.1

There is no password so you'll go right in.

3) Plug a network cable from your existing router/modem (Virgin Media Hub3/Hitron) that provides DHCP address leases into the WAN port of the R8000.
Then plug cable from PC/Laptop into the R8000.
Then use ifconfig to check until you see one of the ports pick up a DHCP address. You can do that with Code:

ipconfig

If no connection try different cable arrangement until it does work.
If still failure try setting fixed IP address on Laptop/PC (e.g. 192.168.1.3).

4) Assuming you get an IP and can get to the internet:

Code:
ping 8.8.8.8

from the ssh prompt will tell you, at this point we need to install and enable the web interface.

Code:
opkg update
opkg install luci
/etc/init.d/uhttpd start
/etc/init.d/uhttpd enable

5) If that worked you can access the device with http://192.168.1.1

6) Go through the initial setup prompts and then flash:

dd-wrt.K3_R8000.chk

7) Wait....... Then power cycle the device and access it via http://192.168.1.1

DD-WRT should be working as expected.

I think there is a switch to force the install of these packages but unsure. Or maybe uninstall and reinstall.
Sorry , but more than this is beyond my knowledge. Hopefully someone else will chip in soon.

opkg --force-reinstall install luci

that's the command to force a reinstall but like you i don't know if it is safe to use here.
