OpenWrt installation instructions for Arris TR4400 v2 / RAC2V1A

openwrt-tr4400-v2's Issues

Installation on devices with an active secondary OS slot

Hi! (Hope this is the right place to raise this):

After the tricky business of opening the case, soldering tiny wires, getting a serial console...

I'm stuck installing openwrt on my RACV21A version Arris TR4400 v2. There's a whole bunch of differences flagged up by check-svn1418.sh (see below).

Does this mean there's a problem with check-svn1418.sh, or can I safely ignore the errors?

This script checks the current state of your router in depth.
If all checks pass, you are good to go on installing OpenWRT.
The router USB port should be empty when running this script.

TR4400 v2 / RAC2V1A

I am curious if this also applies to the SAC2V1A. I found one of these in the trash - It's branded Spectrum (thus the "S" in the model?)

The internals look the same. I was able to setup a serial connection, but never get a root (or any) prompt. At the default bit rate of 115200, I do see characters on the terminal screen. If I change the baud, sometime the correct characters are printed and sometimes not. I assume that means the serial connection is working and the characters are making the round trip to/from the router. Correct?

When the Router boots, it flashes blue for ~30 seconds, then slowly fades blue in and out at 1 - 2 hertz. then after a minute or two it fades red in and out at the same frequency. I am wonder if the problem is that it never completely boots. I've tried connecting to the web interface, but it says and will not let me connect. It does auto redirect from http to https. I plugged it into my spectrum modem in the hopes of it getting updates, but nothing new happens. Same colored light pattern.

Now What?
