Anyone know how to bypass the "insert a supported module" error that comes up after changing the charging port?

LOL. Who rated this as a difficult repair? Seriously? T5 screws too much for you? The only issue with the repair for this device is the adhesive between the digi and frame is a REAL pain to remove, and the plastic frame is likely to melt if you use too much/high heat. Otherwise, it's very simple. Just be careful when installing the new digi, as the motherboard needs to be slightly lifted to feed the connector.

The "home button" repair shows the physical button, but it's not actually the repair for the switch, which is what should be shown as the home button repair. The switch has a little black plastic tab that breaks off with excessive presses, and that's why the button plate cannot engage the switch when the screen is reinstalled. You will need to replace the switch, or modify it with something small enough to press the switch when the LCD is lowered.
