macbook pro stuck on boot after installing 10.12.2

My mid 2010 17" MacBook Pro is stuck on reboot after I installed 10.12.2

It just repeats

SmartBattery: finished polling type 4 over and over.

The type 4 changes to type 2 if I unplug and plug in the magsafe power cord.

I have tried:

Resetting the NRAM

resetting the SMC

booting with option and running disk repair

doing a safe boot (shift)

disconnecting and reconnecting the internal battery

booting with cmd R and reinstalling Sierra over the internet.

booting to a USB Sierra install disk which will then boot the machine and give me basic repair options including Terminal

Nothing has worked so far and I have the same problem.

Ant suggestions short of backing up, reformatting the drive and installing from scratch ?

MacBook Pro (17-inch Late 2011), OS X Mavericks (10.9), Belkin F8T067 bluetooth keypad

Boot on recovery mode and restore your device from Time Machine to the previous Sierra version. I did it and got rid of the problem. Some people are suggesting to enter your password even on the black screen that appears after loading bar get stuck. I don't like that work around. By the way, I had not any of those third party extensions some people are commenting neither use Onyx or AVG or whatever. It's simply an issue Apple should fix. Let's stop wasting time and prompt Apple to do it as soon as possible and send a new update.

The point is that my last TM back up is almost year old. I would not bother guy here if I had it :(

I need to get to know why it fails and bypass that :(

It was the two HUAWEI extensions in my case. Would like to know what extensions I have to necessarily keep.

Hello domdias,

I just went to Library/Extensions and took out the .kext file by putting it at my desktop (needing administrator password). That was enough to be able to do the update.
