No you don't need to have Unlocked bootloader but If you are just flashing Stock rom and if your are going to flash any custom recovery and root it then you need to have Unlocked bootloader !

Hey I need help "fastboot flash system system.img_sparsechunk.5" not working for me
Please help
can you write down the error you are facing while issuing this command
Forget it, that command was not necessary.
I had a bootloop problem but now my 3G is working.
Thank you so much!!
I mean Moto G 3rd gen
Update of Marshmallow on G3 sucked. Had to rollback to Lollipop in legit way. This worked. Thanks (:
yeah !
Man, I just unlocked the bookloader and my phone got on normally and bootloader is unlocked.
Now i installed TWRP.
Til here everything is okay, but as soon as i tried to reboot in system through TWRP it asked me to root my device, so i swiped and rooted it and from that moment my phone is hanged on that bootleader screen which says "WARNING BOOTLOADER UNLOCKED".
Please let me know if by flashing stock firmware will my problem be solved?
BTW I'm having Indian XT1550 model of G3.
FYI I'm running on Marshmallow.
you can download the stock rom zip file and flash it through recovery no need to follow above steps that one will be easy and fast and next time don't swipe in twrp to root it will go into bootloop.
i am having the same problem, stuck on bootloader, i can use twrp recovery, but cm12.1 is not flashing, the conidtion is the same. i am downloading firmware for x1550 as we speak, let me see if it works out or not.

I rooted my moto g 2015 xt1550(osprey) and tried few Custom ROM's.
Then I switched back to stock rom to marshmallow with the help of the file which was provided by lost101 . I did exactly how it was written every thing went well, my cell booted normally. Then I replaced the recovery by TWRP file. After that I installed SuperSU file from TWRP and when i restarted in system it got stuck on boot loop.
1. I tried installing ROM again and TWRP that time it started well but as i install SuperSU it gets stuck
2. When i install TWRP and just boot after some time wen i try switching to TWRP it says no command.
PLZ help i really want my root privileges back. I am unable to understand how to resolve this.
just restore the latest stock rom and then flash latest super su zip file from recovery.Hope so it works for your !
I min a bootloop or my device is bricked.
When I flash commands it says
Preflash validation failed
FAILED .
I ignored and started putting next command at the end my device powered off but not rebooted.
Please help me to prevent preflash validation… Please help me I am in a really bad situation.
Thanks .
just flash twrp recovery and install any rom then you are good to go !
This is what I got. please help

What am I doing wrong?
Can I use this to downgrade from marshmallow to lollipop?
If I follow the steps correctly?
Yes! I did.
I'm facing some different problem, i got OTA update for android 6.0 on moto g3 (xt1550) i installed it and my phone is stuck in bootloop, then i tried your method, again and again i'm flashing android 6.0 but everytime it stuck in bootloop.
I cant even unlock bootloader because usb debugging is disabled so can you tell me is there any other way to flash stock rom without getting into bootloop. THANK-YOU…
Right now I am using cm12.1, thinking of switching to stock 6.0 Now, i wanted to know 1) whether i will get future OTAs after flashing stock 6.0 and 2)which recovery it will be after flashing stock twrp or stock ?

I DID ALL THE STEP U SAID NO ERROR FOUND IN ANY STEP BUT STILL MY MOBILE IS NOT BOOTING. ERROR IS "FAILED TO VALIDATE SYSTEM IMAGE, ERRROR FAILED TO PASS VALIDATON, BACKUP TO FASTBOOT"
FASTBOOT REASON: FALL-THROUGH FROM NORMAL BOOT MODE
i used kingroot app to root my moto g 2015 indian variant with 2gb ram 16gb internal.Now my phone is stuck in fastboot startup loop.Plz help.
It's weird to say but, yesterday I was using "kingroot", after an hour of doing some processes, my Moto G 2015 with 1gb ram, 16gb and dual-sim started to restart. Few minutes before that, I could see that the phone was to slow, so I decided to restart it. Due to that as I said my Moto G3 started to restart but there were two problems. My net and my wi-fi are not working. This morning I decided to hard reset, everything was okay. No bootloop or brick, but my net and wi-fi still not working.
I don't know what to do. I'll try to install stock rom lollipop and see what happens
same here…ysteday i was rooting my phone with kingroot but failed nd my phone restarted and stuck with no command error
motorola xt1540
