Flashing stock rom has nothing to do with locked/unlocked bootloader, do you get any errors or what happens while flashing ?
Why it happened ?
Are you trying to flash latest update september's one? If not then try with it (see guide section for steps, download and more info)

yes, unfortunately i flashed gpt.bin and bootloader.img earlier.. i cant factory reset since my phone is stuck at the bootloader screen itself.
your screen shows the moto logo???
hold power button for some time the device will shutdown. then press and hold vol down and power button after the decuce boots into bootloader use vol buttons to boot into recovery...then go to recovery and factory wipe

no..it doesnt show the moto logo....even i tried doing the recovery....but after i start the recovery the same problem arises the phone restarts and stops at the bootloader screen.
someone had this same problem see how he solved look for see post 9 http://forum.xda-developers.com/member.php?u=7015800 he eventually solved it.
Maybe you have to reflash the Marshmallow "fastboot flash partition gpt.bin" and "fastboot flash bootloader bootloader.img" from the Marshmallow rom again.If you followed that downgrade guide this wasn't happened.
I would try flashing everything except the 2 lines for the bootloader and see if the works. I had the original moto x from 2013 and people would hard brick their devices by flashing back to an older version of Android. You may have a paper weight
a question, your device has unlocked the bootloader ?
try this code
fastboot oem fb_mode_clear

How did you managed to flash the ROM since your bootloader is locked, which means no custom recovery installed ?
Does
Code:
fastboot boot recovery.img
works ? (BOOT, not FLASH)

Hi casual_kikoo,
thanks for reply!
I tried to do fastboot boot recovery.img, but not worked. No customer recovery.
I fixed it, following this guide. ( after a lot of windows's driver problems )

Strange problem with Re-Locking bootloader

Hi guyz, i've a little problem here.
I've to Lock my bootloader. Now i did it several times, with different tools too. Now:
If i use correct droidboot version (lollipop one) and flash it, the bootloader is not (secure), so not locked.
But if i try with a tool and it flashes the KK fastboot, it works, it's relocked.
Can you tell me why? Thanks!

Seems the Lollipop fastboot doesn't have the signature check that kitkat fastboot has.
But, even you can flash custom files with locked bootloader and lollipop fastboot, the system don't boot, stucks at USB logo, so it means the bootloader is locked.

Yes, I tested in my phone, flashed custom kernel with locked bootloader and fastboot from Lollipop .87, flash sucessfully, but when I try to boot... USB logo.
Only KitKat fastboot has signature check.

Yes, same on my device. I think it's normal.
Yes, fastboot mode of lollipop firmware on ZenFone 5 / 6 is able to flash custom kernel / recovery, but it won't boot until bootloader unlocked.

Turbo 2 Soft Brick

My friend just sent me a soft brick DT2. It was bricked because he downgraded from Nougat to Marshmallow. I've tried flashing it using RSD Lite and minimal adb command still resulted in failed. It won't boot to normal. Stuck always in fastboot screen. Any ideas to get it fixed? Any helps will be much appreciated. Thanks in advance.
You can not flash Marshmallow without unlocked bootloader, try to flash stock Nougat again.

so your bootloader was looked when you tried to "update" rom?
if so thats your issue. you can try to connect to pc and put phone in fastboot mode and unlock bootloader.

No they cant. Fastboot oem unlock only works with the T-mobile variant (unlock works without a key but is missing flash commands) and the us unlocked us996 can unlock by flashing a key from lg but can actually flash roms.
@uccfar is using the term rom when meaning stock firmware, and if this didnt happen when rooted or trying to root it could easily be a hardware issue.
