Issue updating Intellitouch Firmware from 1.051 to 1.190

[ogdento]

Hey folks,
I just updated the firmware on an Intellitouch system for a fellow TFP member @riverlvr ... his system had an Indoor Unit at T1.051 (Service/Trainer version), and an outdoor unit at 1.130. I updated both to 1.190.

The problem is that he had 1 VS pump set up - but after updating the firmware, the VS pump had changed to a VF and he is unable to change it back to VS... cycling through the types (VF > VSF > VS) and selecting VS has no affect.

The release notes specify a procedure when updating from a version 1.070 or below to a later version... basically they have you:
- update the indoor firmware
- clear the indoor unit's eeprom and allow it to load programming from the outdoor
- clear the outdoor unit's eeprom and allow it load programming from the indoor

That procedure ensures that you're loading your "old" programming into a device running the updated firmware, and it's supposed to mitigate any update issues. I've done dozens of updates to 1.180 and never seen a VS change to a VF... but I haven't done too many to 1.190 - especially on a system running firmware older than 1.070.

Does anybody know of any issues related to the 1.190 update from older firmware?

- update the indoor firmware
- clear the indoor unit's eeprom and allow it to load programming from the outdoor
- clear the outdoor unit's eeprom and allow it load programming from the indoor

Isn't there a step missing here, namely update the outdoor firmware?

Anyway, I'm no expert in these systems, as you are. But I know that some devices end up with errors if their firmware is updated and then settings re-loaded from a much older version.

The device I'm most familiar with is home network routers. Many of them will error if a saved configuration file is restored after a major firmware update. For those devices, the best approach is to do a factory reset after updating the firmware and re-enter the configuration by hand. This means you have to write down or capture images of the old settings prior to updating.

Squirrel you're absolutely right on all fronts - first, I forgot to add the "update outdoor firmware" step to the list!! I did do that bit though

And your router analogy is spot on... I guess it's hard to expect that you won't lose any data when updating a system that is so old.

I just found it interesting that their procedure has worked for all the 1.180 updates I've done (many which were <= 1.070), but not this particular 1.190 update.
