Flashing from MM to N system images via fastboot stuck at google logo

All,

I am not a noob by any means, but when I attempted to manually flash the img files via fastboot for the latest N build from the factory images coming from the last 6.0.1 build I get stuck on the Google logo. I checked the commands and re-flashed again and the same result happened ( i did flash radios and BL ) .

I even tried to format data ( i had backed everything up ) , still no go and stuck at google logo still. I could access BL and able to access TWRP.

I got frustrated and flashed the 6.0.1 images including BL and radio via fastboot and booted up just fine. I then rooted, installed flashfire and used the OTA and Android N installed just fine.

Does anyone have any idea what could be causing this. I am currently on N, but wanted to do a clean install .

Thanks in Advance

fastboot flash system system.img
fastboot flash vendor vendor.img
fastboot flash boot boot.img
fastboot erase cache
fastboot flash cache cache.img
fastboot flash recovery twrp-3.0.2-2-bullhead.img
fastboot reboot-bootloader
fastboot flash recovery twrp-3.0.2-2-bullhead.img

Flashing mtc20k works successfully
Using the same commands to flashing npf10c results in stuck the google logo

In order for me to even get on N I have to me on 6.0.1 then either use the bullhead-ota-npf10c-d1785fea.zip on the root of the SD card and use flashfire OR use the following command from stock recovery
adb sideload bullhead-ota-npf10c-d1785fea.zip
The later is what I did recently, but both will work to get to N.

So why can I not simply flash the factory images like for 6.0.1?

What happens when you flash a Nougat factory image that is NOT a developer preview? Try flashing NRD91N from here:

I don't usually flash cache or user.

Try this instead and see if it works.

Instead of flashing cache.img

fastboot erase cache
fastboot format cache

(if you want to reset user)

fastboot erase userdata
fastboot format userdata

I have tried fastboot erase userdata and fastboot format userdata and fastboot erase cache
fastboot format cache and that never worked.

I tried that factory image before and resulted in the same, however, I will at sometime attempt to do the final of 7.1.1 once it is available sometime in December 2016 and hopefully will resolve the issue.
I will stay on DP1 right now as i find the battery extremely excellent, the Visual VM is back now, and i notice some notifications are coming through better than in 7.0. (I read an article earlier today about notifications and the pixel not coming through)

Thanks in Advance for the people that did come through so far and wanted to thank you for your input on the matter and if i don't have a pixel by December I will try this out. :)
