[Moto G4 Plus Guides, News, & Discussion] graphicsxp:
Hello,

Hoping to get some help here. My Moto G4 Plus is no longer booting since it crashed yesterday.

First here's what I did recently. I was still on Android 7.0 and when I checked in system settings, I had the option to upgrade to Android 8.1, which I did.

It ran perfectly well for 3 days. Then yesterday I received a system notification to let me know about a new feature. It was something about keeping the screen on while the user is looking at it. I was given the choice to activate this option or to be given a demonstration. I touched the "Demonstration" button and ... the screen went blacked and the phone rebooted.

The problem is that I get the red Moto logo on blue screen, then the screen goes black, and I then get the Moto logo on blue screen again and so on...

So I pressed the Volume Down button to get into fastboot. Then I tried the Recovery mode, but I get into the same boot loop. I then tried a Factory mode, but again the same boot loop.

Next, I plugged the phone to my computer and tried to reinstalled the Firmware (ATHENE_RETAIL_8.1.0_OPJ28.111) using RSD Lite. It reinstalled successfully, but again same boot loop...

Next, I opened the phone and unplugged the battery to force a reset. Again, same boot loop.

I'd like to reinstalled the original firmware (ATHENE XT1642), but my phone is locked and obviously I cannot unlock it since I cannot boot to activate the option in the developper options.

Any idea what else I could do ?

Here's the output of fastboot getvar all
