Seems like your bootloader is locked and you are either trying to downgrade of flash a custom image. You will need to unlock your bootloader first.

[Q] Confuse about Booloader & Rooting

Hey Guys, I decide to unlock the bootloader and root my Moto G so i start to read about it and preparing everything to do it in my pc (drivers, etc)
But when i start to read de Resource Guide Thread in the General forum i read something that confuse me specifically in the Root part that says:
"If you do not have or do not wish to unlock your bootloader then you can opt for @oasoas014 's method ( http://forum.xda-developers.com/showthread.php?t=2583652 ) of bootloader downgrade. You may also visit @Cooptx's more detailed guide ( http://forum.xda-developers.com/showthread.php?t=2585755 ) . Note, with the most recent recoveries, you do not need to downgrade your bootload"
But reading the @Cooptx's method says that need unlock bootloader, i really dont understand the @oasoas014 's method but reading all the comments says also that i need unlock bootloader.
So im kinda confuse here, is that im not reading well? or i just need to unlock it? someone can give me a strait answer?
You must unlock bootloader if you want root, there is not other solution for moto g atm. Maybe in future there will be an exploit to root bypassing bootloader like on moto x but not now.
Thanks you, the info is kinda confuse, im gonna put me in to work. Hope eveything goes well

It's not that much work and Motorola makes it really easy to unlock the bootloader If you still need some help or run into trouble let us know!
hey
i tried to unlock bootloader via motorola web site but it says my device does not qualify for unlocking
tried flashing recoveries, root zips and updated to official kitkat, but still does not work
phoned motorola support and they said motorola doesn't guarantee bootloaded getting unlocked, it depends on luck
any suggestion?

HELP My Razr is bricked (?), can I unlock the bootloader and unbrick it?

Hello, I'm kind of a noob on these things but here we go:
My Razr is stuck on the red Motorola logo (the boot animation when you turn on the phone) I believe this is what you call "bricked" (?).
I found out some methods here about downloading an XML file and replacing it but where can I find this file? And where do I need to replace it, it is on the firmware file, right? I wanted to get a USA firmware because in my country (Mexico) the KitKat update hasn't been liberated for us and I want to be able to update it.
A friend told me that if I put a firmware from USA it would ask me to update but to do this I need to unlock the bootloader.
I saw a tutorial on unlocking it with Motopocalypse but to do this I need to put the phone on Debugging Mode and I can't do that since my phone is bricked.
Is there a way to unbrick my phone and being able to install KitKat?
If not, of course my priority is to just unbrick it asap regardless if it is with KitKat or JB :/
Thank you so much in advance.
First, you need to tell us exactly what you did that "bricked" it. And I say "bricked" because if you can get to the Motorola logo, it probably isn't really bricked.
Either way, your friend's advice sounds like a bad idea to me. The US firmware is meant for the xt926, which uses Verizon's network. You should either wait for firmware to be released in your region or use a custom ROM (something you can do if you end up unlocking the bootloader).

When I turn it on it is stuck on the red Motorola logo, it goes like that for hours until battery is dead.
I can go into the bootloader options (when you press vol +/- and power) and I have tried wiping all the data to factory settings but the result is the same.
Sorry if I'm using the wrong terminology.

Can I do that even if I have never unlocked my bootloader?
Update:
I tried flashing with my carrier firmware and deleting the proper lines on the .xml file, then opened with RSD but it shows:
"Failed flashing process 14/21 flash boot "boot_signed" -> Phone returned FAIL"
And on the Fastboot manu on the phone it shows:
"Partition (boot) Security Version Downgraded"
"preflash validation failed for boot"
Please help me

If you never upgraded to KK you don't need to have unlocked bootloader, but why don't you unlock your bootloader? I see only benefits with.

Is not that I don't want to, it is that I can't. I'm having trouble flashing the firmware.
Just follow the tutorial http://www.grupoandroid.com/topic/71673-instalar-un-firmware-por-fastboot-en-imágenes/ and use Claro Puerto Rico firmware, then take the OTA

I did but it got stuck on the "boot_signed" step (RSD lite), deleting that line on the XML file and then it showed the "system_signed" step error, deleted that line on the XML and it apparently flashed successfully but the phone is back to where it was before, stuck on the red Motorola logo boot animation.

What root method were you attempting? Kingroot?

Yes i was using kingroot without an unlocked bootloader. Idiotic really. Do you have any solutions ?
Just see this thread, -

Another user had the same problem. The only difference in your case would be your firmware (XT abcd 1/2gb) and no. of sparsechunk files present (must flash them all).
