Is OEM unlock toggled in your settings screen? That is an option that must always be on if you intend on messing around with any device. If it is, try unlocking your bootloader again the official way. If OEM unlock was toggled on before it should work, then flash stock again.
If it doesn't work, have you been able to enter recovery mode?

Yes, oem unlock is toggled. and i tried the official way but i was unsuccessful. i unlocked oem before and it is unlocked. but the problem is "flashing_locked" in fastboot mode and i'm unable to flash anything via fastboot.. i already installed twrp before and using it..i can flash any ROMs via TWRP but not via FastBoot.. i wanted to give my mobile to my bro but before that i want it to be like how it was when i bought... if any solution plz help..

Hi, I have the exact same problem "flashing_locked" in my Moto X4, did you solve this problem?

In my case I do not have TWRP anymore and I do not have to boot the system ...
I can not enable the USB debugging option...

Sorry for the late.
just to be clear but could you still get in the bootloader?

Sorry for the delay in replying.
I sent my device yesterday for the warranty.
They said it was necessary to change the plate and the guarantee will cover.

I could get into the bootloader, but I could not do any flash files, as I requested to enable USB debugging, but since there was no system and no boot, it was not possible to enable this option.

The Flashing unlock options did not work.

Thanks for the help.

You can just type "flashing unlock" without enabling USB debugging.
And What did it say in the command prompt?

Pessoal que está tentando com o "BOOTLOADER BLOQUEADO" esquece só fazendo reparo via EMMC, tem que abrir o aparelho e regravar a ROM direto na memória CHIP, muitos técnicos falam que é problema de memória ou terá que fazer a substituição da placa mãe, agora se vc já tem o "BOOTLOADER DESBLOQUEADO" é só mandar o comando no adb Fastboot desbloquear o flash que já será necessário, o pessoal fica repetindo as respostas como se nós chegassemos até aqui e não tentamos nada, já tentamos de tudo mas infelizmente é isso! achei um rapaz que faz esse procedimento só que ele cobra 250,00 no Paraná
