For the past few days i had been postponing a 40mb security update that came on my Moto G4 Plus. Finally today i decided to do it and it was downloaded as usual and the phone rebooted and it started installing the update. It was all going fine but as the progression bar filled all the way through the phone black screened and has not yet booted up. When connected to a computer the white notification LED light keeps blinking continuously. Please help.
Moto G4 Plus didn't boot up after official security update installed itself

- Start date
Please give more details,.. Have a look at here https://forum.xda-developers.com/mo...-question-noob-friendly-t3526598/post73395955 and read ahead!
He bricked his phone and its also blinking. Did you do the same with your phone?
If your phone had been modified in any shape, then that's the result. You need to start by flashing a standard ROM in fastboot (or rdslite if fastboot mode is not working), maybe directly the last one:

The phone was fully functioning before the small official update. The bootloader is unlocked. It's running the official Android N for Moto G4 Plus. There is no custom recovery installed.
Boot issue
My issue is somewhat similar but whenever i connect the phone to a computer and hold the power button or any other combination for few seconds the computer recognizes the device for few seconds and then it disconnects due to unsuccessful boot.
Even a custom logo will trow a stick in the wheel.
Try to enter fast boot first. If that doesn't work, tray the RDSLite path.

I visited the local service center for Lenevov/Motorolla and they have checked the phone and come to a conclusion that the motherboard indeed has malfunctioned hence the battery power and the software isn't working properly. I've been asked to replace the motherboard. Thanks for your help.
It means that your battery is not functioning well. In case if it is not a hardware problem
Try the below step.
Plug in a charger of another phone with current output greater then 1. And then press volume down key and power key simultaneously. If the device woke up in fastboot mode then you are lucky. If this does not work leave the phone in charging for at least one and half hour. Then try the button combination again.
Battery working fine
The guy said the battery and rest of the parts are functioning well and do not need replacement and i don't think using another charger is gonna do anything in this case. Thanks anyway.
i faced exactly same pbm today. ditto. i just gave it to service centre, hope ghost screen n boot both be fixed 
Today same issue happen to my moto g4 plus as well after downloading security phone went for installation and never turned on after that.. anyone solved this issue or service center is the only option??
Have you read the whole tread already? There are solutions provided. Or which issue you are meaning exactly?
Did you downgrade or flash an older stock ROM at any point? Which update was this, and what stock firmware did you previously have on your device?
If you plug your device into your computer, is it still recognised or is it detected as a Qualcomm HS-USB 9008 or similar? If so, you may have hard bricked your device. Try this blankflash in the following link to repair your device bootloader and then flash the latest stock ROM (September 2017 patch) to fully repair your device. https://forum.xda-developers.com/moto-g4-plus/how-to/moto-g4-plus-hardbrick-solved-guide-t3657761 for the blank flash, https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138 for the September 2017 stock ROM.

In my case the phone didn't turn on because the motherboard died for some unknown reason while the update. I did take it to authorized service center and he told me it was the motherboard and would require replacement.
