Moto G4 Play doesn't turn on disconnected from USB, can't boot into recovery bootloop

Today I was remembered of an issue I had already faced with my harpia, it's an weird state of bootloop in which even a full firmware flash won't solve anything.
If your harpia has the following simptoms:

1. Doesn't turn on, but you notice you can access the bootloader when it's connected to a USB cable(charging, with the other end either on a computer or on a socket)(If you only connect and don't press Power + Vol - it goes into bootloop again);
2. Bootloop (when connected) - doesn't even vibrate, only shows the Motorola boot logo for some seconds (sometimes a little bit longer for some reason) but then reloads it and keeps bootlooping;
3. You can access the bootloader (when connected via USB) and flash but it keeps bootlooping;

Then you might have the same issue I had!

One could think the problem is a faulty or old battery, but it's not - SOLUTION: Change the daughterboard.
Yes. Weird, right? I don't really know what it is but some problem with the daughterboard (the little second board that has the USB port, also called 'charging board' I guess(?)) causes harpia to bootloop.

I also noticed that harpia doesn't boot at all without one of those, at least my model (XT1603.)
I'm posting this here because I saw some old posts on lenovo's forums which had the same symptoms as I found in my harpia but didn't get any help from Lenovo, aside from the good old "send it to a repair shop".
Hope it helped!
