reverse bootloader - Motorola One Vision Questions & Answers

Hello guys.
I unlocked the bootloader but I can't update the Motorola One Vision anymore. Is there any way to reverse the bootloader? or can I update without reverting?
obs: I saw a tutorial to revert the bootloader with the stock rom and using a code to "restore" the OEM of the cell phone. Does anyone know if it works?
I'm a bit of a layman with that.
obs2: I'm sorry for the text it was translated by Google Translate.

If you just unlock by code provided from Motorola and just that , you simply lock bootloader from settings - developer option - lock OEM .
That's it . I've done myself some time ago . I received after , several OTA updates .

but I don't have TWRP installed on my phone, do I have to install it? because without it, from what I saw, I can't pull the OEM Deblocking arrow to the side.

[Q] Will I lose unlock if I install a new ROM?

Hello, my name is Armando. This is my first post here, and I only have one question. First of all I want to say thanks to all you guys, I've found a lot of useful stuff here for my phone Ok, let's go for it:
I recently unlocked my Huawei Y511 to use it on any carrier, and it was succesful (I didn't unlock it by myself, a repairman did it). The problem is... my phone still got all the original carrier stuff (boot animation, some crappy apps and sounds) and I want to delete all of them. I rooted my phone before the unlock (temporary root which I found in this same forum: http://forum.xda-developers.com/showthread.php?t=2130276) and I leave all the stock ROM untouched before the unlock. I noticed that the guy who unlocked it used a "unlock box" named "SigmaBox" and he told me that my phone was able to be unlocked directly, without needing to wipe and reinstall all the software (I give him the phone, then one hour later I have my phone all unlocked, and it was the same way it was before it).
Now my question is... if I install a new ROM or whatever... will I lose my sim unlock?
I don't understand how he unlocked the phone, all I know is that he did a "direct unlock" but I don't know if he used unlocking codes. All I know is that he used some kind of USB box connected from my phone to a computer, and did his magic and surprise, phone unlocked.
Do you know what kind of unlock is this? And how does it work?
PD: Sorry for my bad english, my native language is spanish but I'm trying to improve my english skills (so I didn't use a translator).
I don't know much about unlocking. But I'm pretty sure that you won't loose the unlock status if you flash custom rom

Thanks for your reply, and yeah, I think you are right.
After doing a little research, I found that a "direct unlock" is basically the generation and input of unlocking codes generated by both IMEI and carrier code, and the unlock box generated three codes which only one of them worked and the phone gets unlocked. So, my phone is
unlocked for ever and I won't lose my unlock status even if I install/update/reinstall the ROM.
If any of you guys know something else about this unlock procedure, please let us know!

Relocking Verizon Google Pixel (2016 Model)

Okay so I have spent over 2 hours looking to see if anyone has asked this, but cannot find an answer.
I have a Verizon Google Pixel it was on 7.1 when I unlocked the bootloader with DePixel8.
I have to return it and was wondering how do I relock the bootloader? Also do I need to be back on Android 7.1?
I have since unlocked the updated to android 8.0 (or w.e. the current version of Android is out.) while bootloader is unlocked.
(I AM NOT ROOTED NOR HAVE I INSTALLED ANY TYPE OF CUSTOM RECOVERY ONLY APPS FROM PLAY STORE)
Now one last thing. If I relock will I need to use the DePixel8 method again and give the command fastboot oem lock?
Any help is appreciated. And sorry for being such a darn noob. Kinda new to this.
P.S. forgive me if this was asked somewhere and I couldn't find it,
You should be able to run the command in bootloader mode "fastboot flashing lock" and then toggle oem unlocking in settings off if it isnt already.

Phone just crashed. Could it be because of an unlocked bootloader ?

I opened up the developer options on my Moto G Stylus and went under OEM Unlocking and selected the allow the bootloader to be unlocked option. That was either last week or a few weeks ago because I wanted to root it and put a custom rom on it. I didn't rooted it yet because I'm not sure what roms are good, I only had cyanogin mod roms on my other phones and I'm not sure which rom is the safest and best to use so I still use the stock rom. I turned on Pandora to play music before I went to sleep. When I woke up my phone was in some kind of recovery mode and said something like the operating system failed to boot. Two options were available, 1- to try booting again, and 2-factory reset the phone which would erase all data. I selected 1, and my phone booted up. Could this be because the bootloader is unlocked? Does having the bootloader unlocked leave it suspectable to being hacked? Could my phone have been hacked?
Switching OEM Unlocking is not enough to unlock, you then must on motorola unlock webpage paste code from your phone and, wait for unlock code in email, via fastboot with this unlock code doing finaly real umlocking...

Would selecting the bootloader option to be unlocked in the developer options make my phone more vulnerable to be hacked?
A few hours later my phone did the same thing and went into recovery mode saying that my phone could not load the OS and might be infected or something. I had the same options to either try to load the OS again or factory data reset the phone. How could this happen?
I factory data reset my phone this time. I just hope I don't have some kind of malware.
Mine was hacked like this. Changed stuff so it won't boot back to original. Got into system files and remote control my phone. Is there a way to get back to original without computer? It's useless now

Question Flash stock firmware and lock bootloader

HHello, I wanted to consult something before getting into a problem. I have the moto g100 with the challenge channel, since the Android 12 ota did not come out for this channel, I decided to install the Android 12 retail ota, Everything worked correctly, but now I want to install my original firmware which is RETAR and block the bootloader, so my question is the following, can I flash my original firmware and lock the bootloader?.
Yes if you flash ORGINAL ROM (Android Version) for your device you can LOCK bootloader for your device.
Lock the bootloader at your own risk, this forum has a thread full of people who have bricked their device after relocking.
Phone wouldn't boot into the system after bootloader locking back...
I wanted to help someone whose phone wouldn't boot into the system after bootloader locking back, phone hangs on a red warning. And in the process of experimenting myself got confused and got into the same situation. Unlocking the bootloader...
forum.xda-developers.com
The stock roms found on lolinet won't boot after relocking and you'll loose the ability to flash anything else. YOU HAVE BEEN WARNED! Also, you can't downgrade the bootloader. What this means is that if you flash older Android 11 stock image it may result in bootloop.
I have a G8 doha that was hard bricked a few years ago.. It did not show up in device manger at all, no matter how i tried. Not even the Qualcomm mode. This did happen after locking bootloader or change slot A/B. (Don't remember, sorry). The phone was totally dead, so it was just "archieved for later use".. Then one month ago i found a description on how to wake it up to qualcomm mode by shorting two points on pcb. I tried, and it did work. Phone showed up in device manager, and i flashed blankflash. After that i flashed stock rom. Phone is now working again. I had to do several tries to get it up running. The description on how to do it was not accurate, but i found a sequence to start it. Unfortunately i don't remember exactly. It is something with pushing/holding a button when connecting USB or shorting points on pcb.. Youtube link show how to do it..

Yes I relock my bootloader on the Moto g100 the North American version. Right after I did it I tried to set up my phone and it wanted my last four digit Google pin code and if you didn't do it fast enough it kept rebooting so for a half hour I tried everything under the sun Google kept asking me I want to try another way. But I have two step verification on my Google account so it couldn't send me the code over my telephone number so after a couple tries using the recover my account option underneath which asked you like personal information like your name and everything it finally gave me three options of three different Google emails I have. I got my unlock code and unlock the bootloader without using a PC or a computer. I used bugjaeger. The premium app is well worth the $10 it works super easy and super efficient

how to unlock a locked bootloader ! ( oem greyed out )

So i received a american pixel 4 xl with a locked bootloader. imei starting with 35
i was able to unlock the bootloader here is the steps i took, note im in Australia.
Full OTA Images for Nexus and Pixel Devices | Google Play services | Google for Developers
developers.google.com
the firmware on the device was american,
i flashed my countrys firmware (australian) optus/telstra/vodaphone etc
use adb side load *firmware.zip*
factory reset , booted device on with australian sim,
and boom oem was available ,
(last step is to adb reboot bootloader,
and ./fastboot flashing unlock and you will see a message on pixel.
intially with the Original firmware on the device it would not unlock.. i tried factory reset
/ fastboot flashing unlock etc and it would not work...
anyhoo i have not seen anything on here suggested flashing another firmware origin so i thought this might help those with locked at&t / verison carriers, intially it was GREYED OUT AND SAID contact carrier or connect to the internet.
Hope this helps someone ! as all the forums ive swiped thru have said this is not do-able, lol turns out it is.

The firmware does not determine whether the bootloader is unlockable.
When the device connects to the Internet, it checks its IMEI against a whitelist on Google's servers. If it has been authorized for bootloader unlock, OEM Unlocking will become available.
If it doesn't, it's likely that you have a locked variant.

What if it is already unlocked and I want to relock it? I flashed stock firmware, the bootloader is still unlocked but now I can't lock it again because the option is greyed out.

The OEM Unlocking toggle does not lock or unlock the bootloader itself. It simply allows you to unlock the bootloader when enabled.
If you want to relock your bootloader, you do this via ADB while in bootloader mode: fastboot flashing lock

For some reason I couldn't get into fastboot mode, "adb reboot bootloader" would just restart my device. If I booted into recovery, the "reboot into bootloader" option would just start up the phone. But I eventually found out I can lock the bootloader in download mode
