I'd like to know the answer to this as well. I know its all about the Bluetooth these days but I'm a fan of wired headphones. [emoji442]
As I already said at lineage thread too, my p20 pro was hard bricked when I tried to create an unlock tool for the public.
I sent it to Huawei to fix it, but instead of fixing it they went the easy way around and they changed my motherboard for free. This means that I'm locked again without any way to unlock.
So my days here ended.
If only Huawei allowed us to unlock the devices I could do some magic.
It was my first and last Huawei because I don't like having proprietary stuff at my phone , I don't like being watched and I don't like to wait for a security patch for months and I don't like the fact that they support a device for two major updates and then abandon it.
If I wanted all the above , I could as well buy an iPhone XS max.
I sold it now that it sells at a good price , got almost all my money back and I'm waiting for pixel 4xl.
Goodbye Huawei and good luck.

Sorry man, that sucks. The effort was and is appreciated.
I'm in the same mindset with proprietary hardware and software. It's why I stayed clear of apple, Huawei seemed to be pretty open with their unlocking until they screwed us.

Might catch you in the pixel dev in a few months then. All the best till then.

Hey guys. I would love to revert to stock emui. How should i go about doing it, whats the easiest way?

Thabks in advance?

Just use praetorians tool to flash it over.
There is a guide for that in the guide section.

It's a tool where you have to place the update zip.

You could also try to use the recovery to do the work for you I think.

Okay (sorry if I've missed it) I'm new to Huawei and I've looked online, apparently it isn't possible to unlock bootloader? Do I need to unlock bootloader to install this ROM? Or can it be done just following the instructions with a locked bootloader. Thanks

Yes you would, and Huawei/ Honor devices cannot be unlocked anymore. Unless 3rd party companies start up again, but I highly doubt it.

Perhaps in the future if Huawei takes a big financial hit, but again I doubt it.

Thanks for the reply

What do you mean you cannot unlock to bootloader?

How to Unlock Bootloader on Huawei P20 Pro
Connect Your Android Huawei P20 with charger and charge Fully.
Go to Settings > About > Software > Build Number.
Tab 3 times on Build Number. The developer mode will ON in Huawei P20.
After then, Go to Developer Options in Settings.
Enable the OEM unlock option in the Developer Options.


Worked like a charm. Maybe that isnt the bootloader?
Anyways. Cheers.

Haha well you're missing a massive part of the equation mate.

You need a bootloader unlock code which you will no longer get from Huawei.

Turning on OEM unlock means you are saying yes I will allow the bootloader TO BE unlocked, but that is not unlocking the bootloader.

You would need to obtain the bootloader unlock code (which you can't get)

Then using CMD you would use the code along with the unlock command.

Sorry but you are out of luck. Unless you obtained an unlock code by June 2018.

So much for that working like a charm eh?

Lesson here is, don't buy Huawei or Honor.

Period.

    !!! Flash on your own risk !!!
    We will not take any responsibility for bricked devices or lost data. So please watch out!

    If you are coming from stock EMUI:
    - WIPE data and cache in stock recovery_ramdisk
    - While plugged in, hold vol down during reboot to boot to bootloader
    - Flash TWRP in recovery_ramdisk partition
    - fastboot reboot and unplug cable and hold vol up until you see the TWRP logo

    If you are coming from another rom:
    - Format data in stock huawei recovery before flashing AOSCP

    - *if your p20 pro doesn't boot after flashing the rom, flash the stock PIE KERNEL.img to kernel partition.

    If you are already running AOSCP:
    - Reboot to TWRP
    - Flash rom, gapps (Always flash gapps because only the official builds support OTAs)
    - Reboot and
    - Enjoy CypherOS on your device!

    (in this post i will edit and add useful links and information)

    1 )
    just in case you don't already know it, when you dirty flash an update of my unofficial builds, you also have to dirty flash your gapps package too.
    Only in the official builds the OTA can survive the gapps installation.
    2)
    For Huawei camera app --> press here

    i will use this post to make announcements.
    Its easier to see announcements here.

    Keep in mind that im working way too many hours and i won't be able to maintain it daily.

    Thank you for your understanding.

    1 )
    You need firmware 9.0.0.195 or newer.
    Any firmware update since v195 has the same kernel, they are only security patches and minor bug fixes in EMUI 9.
    Currently i'm at v270 and everything is fine. If you are already on v195 or newer , there is no reason at all to update to the latest because we only need the kernel, we don't care about the EMUI security patches and fixes.

    NFC and Stock Camera are working?
    Sorry I can't test nfc with payments. For file transfer it works.
    The problem is that in Greece we are 500 years behind. Until we start using nfc payments here , in other countries people will use aeroplanes instead of cars.
    Yes stock camera app of aoscp works. Also Google camera mods work. I don't know about the Huawei camera app, I don't have time to test.

    GPS navigation has some issue but I already fixed it and I'm pushing an update.
    I also fixed aspect ratio and if you or anybody else finds a bug , report it asap with a logcat.

    Hi,
    i have a Big problem.
    I have a p20 pro with emui 8.1 and patch november 2018.
    I want test modding rom but is impossible unlocked the bootloader.
    I ask a ministry of solution but i said that impossible because P20 is totaly blocked.
    Please give me a solution!!!!
    Best regards
    You can't.
    Locked means locked. Sorry.
    There is a way to unlock but it needs an algorithm to run and test bits until it finds your unlock code.
    And since I don t see many devs here , I don t think that anyone will do that and make this algorithm.
    Only if you pay to unlock it.

    FRP navigation fixed.
    One bug remain there; After reboot we just have to disable-enable the frp navigation and it will work fine again.

    I was working on the battery styles and i forgot to revert before i share the build, but ok.
    You will just have no battery icon, or Circle battery icon. In this build only, the default portrait/landscape battery icon is broken.
    It's already uploading.
    Hi I like your roms
    but it's a little bit difficult to install
    Whats difficult ?
    You adb push in the temporary directory because whatever you push in there, it gets deleted on reboot, so you skip the step to remove junk.

    if you can't adb push inside the temporary directory, use gui.
    Plug in your device after you boot to TWRP and copy paste the rom and gapps inside.
    Hit install in TWRP and install them.

    Sorry but it's up to people to "pressure" the TWRP maintainer to fix TWRP.
    It's also up to people to practically ask for a debug TWRP build and help him fix it.
    Also i don't see people hitting any thanks button.
    If people don't care then the whoever dev is, doesn't care too since he can personally use the phone in whatever way he likes. No need for him to do "extra" work.
