Not installing the BPFs/LPFs shouldn't cause a problem.? You should disable TX for those bands in the band config menu, otherwise it is risky.? Accidental TX when the band is selected or running any of the Hardware test tools or SSB Calibration on those bands may cause failures, since they won't be terminated correctly.? So I hope those bands weren't included in your SSB Calibration; in its beta condition who knows if it is honoring that TX disable setting.

I purchased a couple of very inexpensive (Ali express) "USB&DC Digital Tester"s (mine are Atorch brand) that I always connect inline with a new power source before and while initially using it with my QMX.? It shows voltage and current, and also the PD and QC protocol triggering status when on a USB port.? It has both USB and 5.5/2.1 digital in/out ports.? So I can be confident of the voltage before I plug it in, and watch the current while it starts up.? I highly recommend something like this.? It sounds like the combination of your trigger cable and that one charger were not doing what was expected.
