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,
LongBeardHagrid

Hi all, I need your help please.
I've recently rebranded my CLT-L04 P20Pro to CLT-L29 emui 9 using Funkyhuawei.
After the rebranding the bootloader is still unlocked but FRP is locked
ADB and fastboot commands will not work. I can use fastboot to check bootloader status etc etc but not push commands to write recovery or whatever.
Does anyone have a solution to maybe go back to CLT-L04 ? Thanks
Enable OEM unlock in dev options ? (to unlock FRP)
Or you can't log at all on the phone ?

oem unlock is not unlocking frp...
frp is Factory Reset Protection... only google account delete unlocking the frp
My redmi 4x (santoni) have twrp installed and I it is running on miui pro rom. But it's bootloader locking automatically after enabling usb debugging and switching off the phone. I can't boot into recovery and system, can only boot into fastboot mode, and I have to use mi flash tool to unlock bootloader again.
If someone face this problem, is there any solution of this. Please reply.
Thank you.
Bootloader can only be locked on all available official MIUI ROM, it can not be locked on modified MIUI versions.
There is no way that it'll get locked by itself by turning on USB Debugging and switching off phone. to lock unlocked bootloader one has to clean flash from Mi flash tools and needs to select lock bootloader before flashing.
I don't know how are you able to unlock bootloader on Mi flash tools because to unlock it official way one will need Mi unlock tool with permission from xiaomi(depending on region)
First make sure you are not on fake MIUI if so then flash official one through mi flash tools and then unlock it by mi unlock tools.
Once it is unlocked as i said earlier there is no way that it will get locked itself unless you choose to lock via mi flash tools.
about unlocking again
sorry for mistake, I have to use mi unlock tool again with my mi account signed in to unlock the bootloader again. And can't unlock by fastboot command "fastboot oem unlock".

I still do not get it what exact issue you have and what version of MIUI you are on.
You are saying you are on MIUI Pro and that confirms bootloader is unlocked and now you are saying

Please share exact and more details if you wish to resolve your issue and possibly some screenshot(s) of about phone and errors if any.

I have a similar issue and came across this thread, usb debugging suddenly stopped working, it was working perfectly till yesterday. So when I went to developer options, I saw that the OEM unlocking option is clickable now ( it had remained grayed out ever since I unlocked the bootloader ). The Mi Unlock status option tells me that phone is locked. Toggling usb debugging is not making it work. When I restart the phone, I definitely see the unlocked padlock icon on the boot screen. So I am not sure what is going on. also, magisk is working fine.
In the screenshot you can see that it shows the device is locked. But from the status bar you can make out that exposed is working. I'll have to get another device though to get a picture of the padlock icon though.

Toggle OEM unlock enabled doesn´t mean that the device is unlocked, it only means that the bootloader can be unlocked, there is other item just lines after to check it; Mi Unlock status, enter to it and confirm it.
Also, you can confirm the bootloader status through fastboot with fastboot oem device-info

Yea as I mentioned, the mi unlock status tells me that phone is locked.
Just check via fastboot, and it shows that phone is unlocked.
So do I just believe fastboot, or wait a month and then try to again unlock the bootloader via the mi unlock tool?

You said "In the screenshot you can see that it shows the device is locked" but unfortunately the screenshot didn´t reveal that, I wonder, what exactly it says in the Mi Unlock status apart.
In older days, users share an aboot image, this served to unlock bootloader automatically without make the official process to unlock it, it could be that you flashed the official stock images, and it got re-locked. Anyway, we don´t know what happened with the fastboot command or with the Mi Unlock status section, so no respond to those points.
For the part you say to wait a certain time, definitely, no, the bootloader process is not monitored any more, for older devices, they can be unlocked instantly.

My phone is about a month old, so it does tell me to wait. Contradictory screenshots attached below. After the boot unlock, I did flash flash a magisk edited boot.img and vbmeta.img to disable it. If I remember correctly though it was fine after that.
I dont know how ( i think i did it when i open oem lock [unlock]) but my FRP lock status is "FRP Unlock"
Can it cause to prevent me to install new roms on my phone and if yes, how can i lock back?
Thanks....

If you don't have Bootloader unlocked just go to Settings /System/ Developer options and switch off OEM Unlock (=FRP Unlock)
Btw, there is no need for panic because of unlocked FRP (and/or because of its warning while booting

You didn't state here but from your another post (you installed RR), you unlocked Bootloader and therefore obviously you had to unlock OEM/FRP
If you don't like unlocked FRP, then you first go back to stock Nougat, re-lock Bootloader and forget about rooting, installing custom ROMs, etc - for all that you must have unlocked Bootloader AND unlocked FRP
i need do UNLOCK FRP but on OREO i cant find setting UNLOCK OEM...
EDIT: sorry i read now "Chinese Brands dont have FRP." so i can install directly OPENKIRIN rom without FRP check . My bootloader is unlock

On the 'Chinese' Oreo there is no OEM unlock option in Developers Options, and OEM/FRP always stays unlocked - please consult HWOTA7 OP instructions.
OEM/FRP stays unlocked also if going to Open Kirin ROMs and back (if f
the required installation procedure is followed)
Check in Fastboot, maybe only your Bootloader is locked, and you just need to unlock Bootloader again in Fastboot

Ok, be careful to follow OpenKirin installation guide
Btw, there was a trick to re-enable hidden OEM Unlock option in Oreo, post in the HWOTA7 thread:
https://forum.xda-developers.com/p9...date-tool-hwota7-p9-eva-t3820849/post77296996
With root, open from eg MiXPlorer:
/hw_oem/prop/local.prop
find and uncomment the line (remove trailing character #):
ro.frp.pst=/dev/block/platform/hi_mci.0/by-name/frp
Then reboot, open Settings/System/Developer options and find the belowed OEM Unlock option (see attachments)
I've looked at every guide I can find but nothing works when trying to flash TWRP. It always fails because I'm guessing the bootloader is still locked. I clicked the "OEM Unlock" button in dev settings but ODIN only ever tells me that the secure check failed when trying to flash it. Can anyone help out? Thanks.
You have to get the unlock codes from AT&T. There is a form for that.

Hi Guys
Need your assistance, its a complete mess here.
I found android 14 pre releases in developer options -> DSU Loader -> Installed GSM+ARM64. Thought it will install android 14 pre release (Saw in one of youtube video -
).
Post restart phone it went to system has been destoryed.
1. OEM unlock option was not checked (Bootloader locked)
2. Only booting in fastboot mode.
3. Flashing through EDL/ Flash Auth not working.
I can only think of unlocking bootloader may fix this issue but problem is bootloader is locked. Can't unlock it because oem unlock is not enabled under developer options.
Please help me bypass OEM unlock check so that I can unlock bootloader & probably flashing TWRP or Orange recovery will fix the problem
Thank you
This tutorial is for those who have the bootloader unlocked (see the video at 3 minutes 38, the padlock is open).
What did you want to do?
The phone is bricked, nothing to do with the locked bootloader, see a Xiaomi repair center.
Hi
I missed that it is for unlocked bootloader.
So if bootloader is locked, it should not update the partitions & if so it should roll back to original miui if it fails.
But instead it bricked my phone.
So if someone can help me unlock bootloader I can try flashing recovery & then rom.
Or suggest better option. service center people asked to replace motherboard.
hi!
If there is any way to fix it, unfortunately it is paid.

It is imperative to unlock the bootloader with a xiaomi account where unlocking is authorized and associated with your smartphone. Without it, not worth it...
So unlock the bootloader and apply one of those countless FAQs that you'll find on XDA or youtube.
For me, settled in an hour.
Good luck,

What is the use of this post since the user has the bootloader locked?
