What I was able to verify as long as you don't install an update in the config mode AND your VPX is in communication with the MFD (vs the PFD) you can turn off each circuit in the VPX to help with the install as needed but with 9.51
True. But if not in config mode you cannot monitor progress of each LRU update so you don't know when to tell VPX to turn on the remaining LRUs in sequence.
 
G3X Touch v9.51 is now available here. This update includes an improvement to the LRU software loading process that will resolve the slow/failed LRU code loads a few people were experiencing.
Thanks Justin, I assume installing this is unnecessary if we were able to get 9.50 to load?

Data point - I had to pull all G3X Touch LRU fuses except the GDU-465 and GTR-20 to get the GTR software to load. On the bright side, it took me a couple of tries to disable *all* the power paths to the other core G3X Touch LRUs (ADAHRS and EIS) so I feel a lot better about my electrical system design! :)
