Actually that sarcasm was wel placed if you look at the facts:
The starting question is about a Moto G4 that won't turn on.
Then a service employee asks to turn it on (even if it isn't regular booting)...
I understand the frustration and thoughts about it may be automated answers.
Luckily i always use Sony: turn it off (maybe with button near sim/sd) hold volume down while connecting usb to pc then press software repair and it gets done.
All phone companies should use a similar mode/possibility.
I am trying to repair a G4 also, but also only reaction is the white light flashing.
-USB tester sees some ampère getting in, although not much.
-Installed a new battery, old one looked puffy and charged with only 7mA max then stopped after 21mAh (so it was broken).
-Was able to use it 10-40sec then it froze with dropmenu halfway open.
-After reconnecting battery, which is already hell to perform, it tried booting a few seconds then turned off.
Haven't been able to turn it on since. Tried everything.

Good luck. The phone is probably bricked. That's exactly what mine started doing. I replaced battery, screen, digitizer, - each time I could stumble on getting it to start. Then, at some point, WITHOUT WARNING, it'd be back to flashing white light only. The next step in their scripted replies that they will tell you is "service/repair", likely a new motherboard. Throwing good money after bad.
I repaired mine by putting it on the shelf and getting another brand of phone. No more Motorola/Lenovo/. Had it. Done. They are utter junk. I lost count of the number of times I pulled the phone out of my pocket and it was flashing white light only. It was OK when I put it in my pocket, but at somepoint the MoBo flaked out and put it in "white light" mode. Same deal when I would pick it up off my desk. It was fine when I put it down, but pick it up 20 min (or whatever) later and it's in white light mode.
They are sh1t phones and sh1t support from these script clowns.
Good luck with yours - you'll need it if you keep it.

At first, just now, i thought the battery had to be disconnected and reconnected to work again to get to recovery mode.
Then i found out a most weird thing...
After huffing and puffing 18 screws, with an adjusted torx size, and taking off the frame holding the flash, it could suddenly turn on...
Earlier it also turned on without the backframe...
Why the frick is the flash causing boot issues?
I was finally able to reset with that roundabout method to recovery menu.
As long as i don't connect the flash flexcable it works again.
Gonna make a 4 year old girl happy. She doesn't use the camera anyway, just youtube or games.

Okay, maybe these phones should be checked by a priest or something...
It was fixed... Brought it to my friend and then it wouldn't turn on anymore... I walk back home much later and it turns on again...
Is this thing possessed or something?!

Now that it is working again, i will try rooting and installing a custom rom.
When i was in recovery menu, it gave errors on graphical testing. Also in developer settings, when using graphics overload showing, it didn't give stable readings.
Coupling this to the fact of black screens and impossible boots, the kernel or android may very well be corrupted.
I will tell you more when i am done.

Btw, i am not naive or anything, this is a learning experience for me. What better than such mysterious example.
Besides that, i don't let myself be beaten this easily.
Never go down without a fight

I applaude your tenacity. I lost patience with the G4 during all of the undependability because I didn't have a second phone and was trying to do work and run a volunteer organization with a phone that I never knew whether it would work or not. Impossible.
Since it's not your primary phone - by all means, have at it.
That's the best way to learn!
(I still hate these phones and the company that made them.)
