[SOLVED] Can't unlock bootloader to install recovery and new ROMs

I recently acquire a Moto G GPE, I read several post and also try with this https://motorola-global-portal.custhelp.com/app/standalone/bootloader/unlock-your-device-b and none works. See output:

When you are in fastboot mode, what does the seventh line says?
"Device is ******. Status Code: *"
Also, have you tried this code?
Code:
fastboot oem unlock

C:\HTC>fastboot oem lock

Any help ?

same error

Try "fastboot oem relock"

Why are you relocking Bootloader? It will say Relocked(same as Unlocked) when sending for repair

Hi,
You must use "htc_fastboot oem lock" to do so.
But, warning i did so and my phone was unable to boot. I had to return back to stock by using RUU mode..... :-\
Regards.

So, what should i do to relock the bootloader and make the warning message (of unlocked bootloader) disappear?
- Restore stock recovery
- htc_fastboot oem lock
- Restore using RUU mode
Is that correct?

Safest way would be to RUN A RUU BEFORE LOCK (to ensure complete stock FW).....
Make backup of any data FIRST
Run RUU
Set up phone and ENABLE OEM UNLOCK
fastboot oem lock command
profit

Does the red bits not mean it wants you to DISABLE the oem unlocking switch (uncheck the box)?.

In my case, i was root with Magisk and stock recovery (U11 can temp-boot to custom recovery see txt), tried to unroot whith the uninstaller.zip => here starts my problem : unable to boot to Android, only bootloader and download mode.
No way for me to relock the bootloader => no acces to the developper menu to switch oem unlock on.
So the only solution to save it was runninrg my U11 to RUU Mode and restore it, following this thread : https://forum.xda-developers.com/u11/how-to/guide-htc-u11-how-to-return-to-stock-t3628452
Got it with success, after that i could switch on oem unlock and HTC_fastboot oem lock my bootloader. (with mention ***RELOCKED ***)
I perfectly receided and install lastest official OTA from HTC : 1.27.405.5
I recommended to
- backup all your data.
- restore whith RUU method (This will flash recovery, boot and system to stock).
- Relock bootloader.
- And have fun with the best smartphone ever made !!!

I shouldn't need to unlock bootloader in order to flash stock rom

go to developer options and check the option - enable oem unlock.then reboot and run the command.
Also how can your phone be bricked with a locked bootloader?It does not make sense .YOu cannot flash ROms on a locked bootloader and if your phone is bricked then that means your bootloader has to be unlocked!!!

You do not want to relock the bootloader on the HTC U11. Everything works with it unlocked. If you lock it after rooting with TWRP, you could brick it. That's what I did.
DO NOT RELOCK THE BOOTLOADER

Don't do it! Read my post on the posted thread. My U11 got bricked when I decided I wanted to "relock" my phone and that was it. It is now at the HTC repair center in Texas.
Just wondering why are you attempting to relock the bootloader?
