Revert Here4 Moving Baseline Firmware?

Hello, I recently upgraded the firmware on my new Here4 to the latest and greatest from ublox, but I missed the part where it says that upgrading it might break support for moving baseline.

Can you tell me where I can download the special moving baseline firmware and if there are any special instructions on how to revert to it? Thank you!

You can’t do it yourself. It can only be done by Cubepilot (possibly also by 3DXR and IRlock/NwBlue)

So are you saying that I just bricked my Here4 for any ability to use Moving Baseline in the future?

Yes you can use it as GNSS but without moving baseline. If you are not that far from one of the companies i mentionned, i suggest to ask a quotation for a fresh flash of your unit.

The reply by @Julien is correct. It’s important to follow these directions (copied below).

Nothing is bricked. But if you flash the firmware from Ublox, you won’t have the moving baseline feature.

Thanks for the reply via email @Thomas! As I mentioned in my email, my understanding of that message is that it would disable support for moving baseline while I was on the factory firmware (makes sense), but it was not clear to me that it would permanently disable it. I just assumed I would be able to re-load the original firmware and I would get the functionality back. This seems to be a fairly major difference in the way firmware works on this device vs others, so it probably makes sense to be hyper-clear about the difference in the documentation.

Anyway, as I mentioned in my email, I think maybe a small change to the documentation would probably clear it up for any future misinterpretations from customers. I’ve submitted a PR Denote that upgrading firmware may permanently disable support for moving baseline by jheising · Pull Request #42 · CubePilot/cubepilot-docs · GitHub if you think it might help. Thanks again for the help.

@alphamacaroon thanks for the change request, we have made changes to the text to make it extra clear that reversion is not possible, once updated. Here 4 Manual | CubePilot

@alphamacaroon
Thank you for your reply.

I believe we already have an email thread with you. But if not, you can always get in touch with IR-LOCK support at the link below.

There should be instructions in that email for shipping to the IR-LOCK tech. If you need anything else, please let us know.
