Huawei bootloader unlock error

When I try to unlock bootloader for my device p9 I show error remote not completely ???
I have number to activate .
Enable Developer Mode(Go to Settings >About Phone>Press Build Number until a message said the developer mode is activated) then Settings>Developer Mode>Activated OEM Unlock & Activated USB Debugging. Now you should be able to unlock the bootloader.

Come on.
You will not be able to unlock your bootloader once you forgot to enable the OEM.
If your stock recovery is intact you can use the force update "dload"
If it does not work, it is because your stock recovery is corrupted or has been replaced in this case your only option is DC Phoenix.
You need 15 credits if you do not have a Dongle, you will receive a username and password. DC Phoenix allows you to flash the UPDATE.APP even with the bootloader and FRP is locked.
Fastboot mode.
Good luck!

Access S5 Mini data with broken touch screen and pattern lock

Hi Guys,
Figured I will ask the experts here. My mate dropped his S5 Mini a few days ago, since then the touch screen does not work so he can't put in a pattern to unlock the phone. New screen prices in South Africa is ridiculous, especially for a 3 year old phone. I want to help him get his photo's off the phone but the we can't do the pattern unlock and S5 mini does not support OTG cables, so we can't use a PC mouse etc. Also can't enable USB debugging obviously.
I'm thinking of trying via the Recovery loader or whatever you all it. The stock recovery does not seem to allow mounting of the various partitions via ADB from what I have read, so will I need to flash a custom Recovery like TWRP 3.0.0? Also see you need to have an unlocked bootloader in order to flash a custom recovery. I presume rooting the device with CF-Auto-Root will unlock the boot loader? I can then load the custom recovery after doing the root?
Rough process would be.
1. Boot Download mode -> Flash CF-auto-root -> Reboot | From what I have read this is safe and does not trash any data as its a separate partition?
2. Boot Download mode -> Flash custom recovery -> Reboot | From what I have read this is safe and does not trash any data as its a separate partition?
3. Boot Recovery Mode
Any help would be appreciated as I really dont want to trash his data.
Cheers
Jacques
A locked bootloader will prevent cf-auto-root from even flashing.
The rest is correct.

Greats Kralle Fuchs
FIX
Found the Problem!
The Device say's its unlocked but it wasnt so i unlock it second time and it just reboots after second unlock in to the TWRP.
Maybe it will help someone
You couldn't flash TWRP if you didn't unlock bootloader - and the phone warns you that bootloader is unlocked
If you want to get rid of the warning, you must re-lock bootloader, but it will trigger factory reset
Btw, enable Development options and check if OEM Unlocking is enabled
And in Fastboot, check does it show Bootloader and FRP unlocked

Unlocking bootloader and Install TWRP (I can't enable USB Debugging)

Lately, I had a problem with the lock pattern; I am not able to unlock the phone even when I enter the right schema!
I had this problem for the first time 3 weeks ago and happily it was solved with a simple restart but sadly this time not.
So, I am locked out of my phone.
I have:
Nokia 8 TA-1012
Android 9
USB Debugging: Disabled
Stock recovery
Phone is not rooted
After 6 days of researching to solve this problem without losing my data and trying desperately the most solutions published in internet, it still for me one solution to test before doing a Hard Reset.
The solution is described as:
Unlock the bootloader
Install a custom recovery
Install Aroma File Manager
Delete gesture.key file
My question is:
Is there any way to unlock the bootloader and install a custom recovery without the need to enable USB Debugging?
Or if there is any other solution to unlock the phone without losing the data?
Thank you.
