FRP unlocked but 'OEM Unlock' still disabled

Hi there,
I bought me a new Huawei P9 a few month ago and installed the android 7 update first. I also unlocked bootloader (fastboot oem unlock <key>) and in the fastboot menu phone and FRP is unlocked. Every attemp to install a recovery like twrp e.g. failed. I get the black/orange boot-message that I cant trust my device because its unlocked. Navigating to Developer options and took a look onto the OEM Unlock entry: Its disabled and grayed out. Any ideas what to do? My main target is just to root that device...
Please help me
Best Regards,

Purchased Used P20 Pro with unlocked bootloader

Hi all,
I've purchased a used P20 Pro from a friend which has an unlocked bootloader and has been previously rooted. I normally keep my phones stock so I want to lock relock the bootloader (I have the code) but despite trying to follow various guides I have been unsuccessful.
Would anyone be able to guide me through the process of relocking the bootloader please?
The main reason I like to keep stock is manufacture updates etc and I don't have the knowledge to maintain a rooted phone.

I don't believe that an unlocked bootloader will prevent you from getting updates. As far as I know the only difference is the warning you get when you boot that "you can't trust the phone."
IF YOU BRICK YOUR PHONE IT'S YOUR RESPONSIBILITY
Don't know if there is another way but of you have fastboot and adb you can do it:
1. Make sure developer options are enabled
2. Connect your phone to the computer using USB cable.
3. Open a command window and type 'adb boot bootloader'
4. Once the device has booted into the bootloader mode type 'fastboot oem lock'
This WILL ERASE all your user data and you will have to configure everything from scratch. You will need the unlock code if you ever want to unlock it again so make sure you don't loose it.

can we unlock the bootloader

It ws esy unlocking the bl in g5s+ , what about the z3 play, wife surprised me with this phone, im liking it already, but would like to unlock the bl and eve tually gain root/custom recovery ?
Anyone?

Depends on the model you have specifically, certain ones cant be unlocked such as amazon version. But the steps are the same as all other android phone bootloader unlocks, Steps can be found on motorola website:
https://motorola-global-portal.custhelp.com/app/standalone/bootloader/unlock-your-device-a
The basics consist of:
enable developer mode
enable "OEM Unlock" in developer settings
fastboot into phones bootloader and run OEM unlock commands
copy unlock code from phone that you get using oem unlocking commands into motorola website
receive email from motorola with unlock "password"
enter password into adb terminal
phone will be wiped and bootloader unlocked

Thats what i thought, i went there just to see , looks the same as for my G5S+ , ill likely do this. Is there guide somewhere on instally magisk as im outdated ( an old chainfire guy) just need some hints , doesnt look like twrp works , what about clockwork mod? Thats fine as well, , any good roms? Think 9 is comming?

Magisk root is straight forward. You can either get a working boot.img for your device from a firmware package and patch/flash it yourself. Or boot NOT flash the twrp images from the twrp website and install the magisk zip that way. The twrp for this device hasn't been compiled for flashing. It boots but flashing it to your device will boot loop it. No custom ROMs that I know of but I'm just using stock with magisk and it's fine once you have root to delete the bloat ware apps and install tweaks from magisk.

How to unlock bootloader on Oneplus Nord N100

Hello everybody
I need to know if there is a method to unlock the bootloader for an Oneplus Nord N100 but the BE2015 model (Metro PCS by T-Mobile) because I have not found out how to do it in this Forums
My smartphone is running Android 11 by an update (version 11.0.9.BE82CF).
My goal is to unlock the bootloader in order to install TWRP for a future custon ROM
Thanks to everybody and excuse my English.
Happy 2023

If I understand correctly you have to have the phone for 180(?) days and then "OEM unlock" will be available in developer settings. Then you have to request en unlock token from T-Mobile. (I don't have an american phone, I'm not 100% on the method)
You can get an unstable TWRP for this phone, but it will have very limited functionality. And custom ROMs is basically a forgotten dream on this phone.
Basically what you can do is sideload Magisk through TWRP (you have to use adb sideload command) and some people have installed GSI ROMs.

Really I bought the phone already unlocked, it has the "OEM unlock" function in the "Developer options". Because I didn't buy the phone directly from T-Mobile it's impossible to request the unlock token, so better I continue using it normally until I can buy another phone (I didn't comment but I live in Cuba...)
Thanks anyway for your answer...

I think you might be able to load a European/Global ROM through MSM tools. Then you can use OEM unlock command without token. Rummage through the N100 forums here and you can find guides.

I already searched and the ROMs are for BE2011/BE2013 models and mine is BE2015. My fear is to brick the phone in the process because it has a modified ROM especially for T-Mobile, thanks anyway

If all you want to do is unlock the bootloader I think you can just do this.
** WARNING: YOUR DATA WILL BE WIPED **
1. enable developer options -> oem unlock
2. start adb
3. adb reboot fastboot
4 fastboot oem unlock
if step 4 fails then try
5. fastboot reboot fastboot
6. fastboot oem unlock
The phone will show a screen to confirm unlocking. YOUR DATA WILL BE WIPED.
7. fastboot reboot
The phone should reboot. Unfortunately It will display an annoying message warning the bootloader is unlocked for quite a while before it boots into system from now on.
BTW: I had problems with twrp 3.5 for Nord N100 floating around these forums. Latest is twrp 3.7 which I'm still suspicious of. All of my flashing using TWRP on the N100 has resulted in bricking.
My successful flashes have been with fastboot.
I use TWRP on another phone and it works like a dream.

Hi,
In step 3, do
adb reboot bootloader
This will reboot in the ancient fastboot, not fastbootd. This is in this mode that you can unlock the bootloader.
