Many thanks for the help from all! I made a few mistakes but I got rid of the IDEXX firmware and am now happily running the latest WRT. I wound up having to use gtkterm on Debian in order to send the break character to uboot and get its prompt. Then I was able to get to work and have success.

Thanks again.


Hi, I have a 600dhp with idexx firmware too Sad
Can you help me with the steps to remove that idexx firmware?

I want to install stock buffalo firmware or dd-wrt
Thank you!!

Does anyone have a simplified method for updating the firmware for these IDEXX locked units? I can understand things up to a point, but the method described in this thread gets a bit complicated for my veterinarian mind. I have ine I could really use in my new clinic and a straightforward, non-technical approach would be nice to utilize.

Thanks,
Doc

For one, the link Malachi posted redirects to a self-hosted GitLab which requires a login. Luckily, someone sent the link to web-dot-archive-dot-org wayback machine:

This procedure requires serial recovery; I don't think you can just TFTP a properly edited file. I have no way to offer another simpler method without one of these in hand.

I used the link Malachi posted to de-brick my
wzr-hp-ag300h which is an older version of your router.

The serial pinout for yours is the same as mine.

Correct serial pinout

I'm wondering if doing the TFTP flash method like the WZR-HP-G300NH would work here using an unedited factory-to-ddwrt firmware image. But the fact remains that Doc is looking for something much simpler than serial recovery:

I just received a similar item. I called IDEXX tech support and they told me the default password: "Idexx123"
the user name is admin.

This worked and I was able to upgrade the firmware to standard DD-WRT.


The Idexx default router address is 192.168.222.1 . admin/Idexx123 is the username/password. Password is case sensitive. Just used this information to upgrade one of these to r49492 tonight to coordinate my pis.
