Update Failed and Phone Cannot Start. Only Flash Blinks When Charging, NO START/Boot?

[TrueUniue]

I got an update notification. And clicked to update.

When restarted the phone, the phone went to die. I could not start my phone.

I tried these:
1) Kept my fingers on VOL Down and POWER buttons for 2 minutes (even more), but NO USE.

2) Tried to open screws but my screwdrivers could not fit for them.

I bought it 3 months back, but in Flipkat and no service center near me. Any solution for it?

What update did you flash, and what OS were you on?

What device did you have, and was it charged up when you accepted the update?

* I got June update I guess.

* My device is moto g4 plus 1643 model India variant.

* When I connected charger, LED light blinks that was near Fingerprint zone.
* Tried device manager software, it helped nothing.
* Tried to put my fingers on POWER and VOLUME DOWN buttons, but no use.

Really disappointed as it was a gift from my brother.

Just to clarify - you installed the update and then rebooted or just accepted the notification to begin the update (and then rebooted, after which your device failed to boot)?

Did you have TWRP/root and were you on the stock ROM prior to flashing (or a custom stock ROM)?

The update was downloaded, when installing it went blank and never started up.

* I have TWRP custom ROM before it.

Did you flash a stock recovery before attempting to update? Having TWRP might be causing the hang; try these suggestions from abhi212b https://forum.xda-developers.com/mo...date-build-t3584982/post72114657#post72114657

Can I ask which custom ROM you were on? You won't be able to flash stock OTA updates with TWRP/customised stock ROM.

My phone is in blank screen. NO start up. No fastboot or recovery mode available. Only light blinks when charger is connected. Then how can I do your suggestions? You didn't understand my problem.

My apologies - I looked through your post history and was wondering if the TWRP/rooting performed previously might have prevented your device from booting.

What is your device detected as when you plug it into your computer, is it Moto G4 or is it Qualcomm HS-USB- 9008 (or similar)?

When I connected to laptop, it took detected and installed port Qualcomm HS-USB- 9008. But I didn't see special drive detecting beside my other drivers.

Right, 2 things to try:
1) Try holding the power button down for 2-3 minutes, this may force a hard restart which might break your device out of whatever state it's in.

2)If 1 doesn't work, you may wish to look into trying a blank-flash (here: https://forum.xda-developers.com/moto-g4-plus/help/solved-unbrick-hard-bricked-dead-t3585016 or here: https://forum.xda-developers.com/showpost.php?p=71405834&postcount=23 ) Depending on what happened with the update, you might be lucky. You may wish to have a look at these blank-flashes too, heed the warning: https://forum.xda-developers.com/showpost.php?p=73151763&postcount=6

3)If 1 and 2 don't work, then unfortunately you'll have to locate a repair centre (or try to find a Motorola service centre) that you could send the device to, or ask Flipkart for assistance. Alternatively, save up for another device. Currently, we don't have another option, though it appears that a member is trying to patch a blankflash for the new update: https://forum.xda-developers.com/showpost.php?p=73152979&postcount=21

I think, if any one can find new blankflash, I can fix my phone. I think those blankflases are old. I'm on April update, and failed when I tried for June update.
