Ram0396 If the bypass charging is working after a software update then the required hardware was also present from the beginning but was disabled for some reason. During bypass charging the current doesn’t go through the battery to power the device, it draws power directly from the charger, and it requires a specific hardware to do that.
I remember similar type of thing happened with Nokia Lumia phones back in the days. After a software update some Lumia devices got FM Radio, and for FM Radio there should be a seperate chip, it’s not just a software thing. So, those phones already had the chip but disabled due to some reason and a software update enabled that.
