if huawei stop the bootloader unlock program, no custom roms will come over to the p20p.
LOS is the only one until now, but without stock cam, what I've heard.

THey did not stop, you just have to write to support and ask for it. Worked for me and for many others
Write down:
Model : CLT-L29
Nr seryjny: xxxxx
ID prod: xxxx
IMEI: xxxx

Official they stop after 60 days with bootloader unlock codes.
if it stays that way, the custom scene will take even more distance from Huawei or EMUI.

I think it's quite likely they'll change their minds about bootloader unlocking. It's generating a lot of negative publicity at a time when they don't need it - withdrawal from US market.
As far as more non-Treble based custom ROMs coming ... the kernel source isn't out yet, which helps. Huawei usually take 4-8 weeks to release it. It's now been about 6 weeks. So hopefully it'll be out in the next couple of weeks ... unless they've decided to stop supplying source code as well as unlock codes.

Is it possible to flash a treble enabled GSI ROM when you have a locked bootloader?

Excellent. Looking forward to it
On en.miui.com it is said that bootloader can be unlocked at request like in latest miui versions of other models. For me this choice makes perfect sense: if you are good enough you can unlock it, otherwise they don't encourage it

"If you are good enough..." - What does that mean ? As is in if you are a tech head or ?
EDIT:
Until someone actually uses it and proves it does it job, ideally Xiaomi themselves. Don't trust it.

It will be locked - http://en.miui.com/thread-231030-1-1.html
and receiving unlock code from xiaomi will take months if you are just a normal member of miui forum. Even after that, it is possible you are stuck by some weird errors .. just take a look at redmi note / 4c forum.
Thought to but MI 5 on first day.. but not anymore.. have to search for other alternative.

Will it be possible to flash the rooted global version on locked bl? That's all I ask at least for months
"Will it be possible to flash the rooted global version on locked bl? That's all I ask at least for months" I'd really like to know that as well
You need an unlocked bootloader to flash roms
As long as xiaomi dosent make unlocking bootloader complicated ...I am ok with it ...but if we have to get codes ,permission etc for xiaomi it will be a hassle ...
either way this beast has to be unchained ...sooner than later I hope

Because if the bootloader was unlocked by default, people could hack into your phone or access it's data by bypassing the code on the lock screen

not like a locked bootlocker is synonymous with encryption, nor that it makes a phone unhackable. so if that is really their argument, i call bull****!
I dont get this locking at all, be it xiaomi, samsung or whoever. If I buy a smartphone, I want to own it, having full control over both hard- and software. Anything less is unacceptable to me.
If I buy a computer or laptop, I can always install another OS on there and am not forced to use the software that came with it. Why can't smartphones be the same?

Well see that is the thing. There are not opensource bootloaders for Android that could completely replace the bootloader on the device. If you did remove all the OEM software on a device you would have to load even the base bootloader by a jtag device before you would even flash an OS to the device. The bootloader is under the TOS you agreed to when you bought the phone. The hardware you own. The software you buy a license to use. You dont own it.
As for why they do it. One guy got an email reply when he asked and it is simple. They didnt like people removing their services (which is how they make money) So they locked the bootloader so you could only flash MIUI roms with their inbuilt services. Anything else they say is just more BS to come from them.
Also for your PC comment. That has recently changed. The windows 10 32 bit computers come with a locked bootload as well, you have to go through a TON of bs to get it unlocked.

Why? They've been out over a year right? If anything that pattern is indicative of a pretty long wait for mi5 sources.

Mi3 was launched in late 2013. I bought it on like September 2014. No custom ROMs were available. Some months later Ivan (he is not official Dev). But his work is closest to official ones. So hopefully he may release AOSP ROM from official sources (he doesn't share them).
About Mi3 kernel sources, they were delaying it. And it was said that once Mi4 will launch they will release. After launch more delays. And finally after months passed of Mi4 launch they released the kernel source. (it may not have all the modules)
But for Mi Note, it's relatively quick.
Similarly it may take few months.

I'm guessing Ivan will make AOSP rom (based on Marshmallow) for Mi 5 like he has done previously. Should be good

In Terms Of Custom Roms & Kernels What Can We Expect ?

Is this influenced by Project Treble ?
You'll be able to run a stock rom via treble just like you can with the p10/mate10. That said, why would you want to? The camera will be straight trash on a custom rom.

It depends on what you take from this question:
1) Custom ROM based on EMUI, or
2) Custom ROam built from source.
If the P10 or Mate 10 series is anything to go by, there won't be many if any options of EMUI based customised ROMs. However, with the work that PHH is doing, he has stated earlier today (to a question of mine) that he will be looking to have his treble builds support the P20 Pro.
On Source built custom ROMs, you might loose things like the camera however there is also a potential that this could be ported over. Again, PHH has done some work to port over the Huawei camera to the Mate 10 etc but he also said he wouldn't be looking at this for the P20 Pro. Might be that we have to hope for someone else to try this task, I know I don't have the skill set for it.
Treble will definitely make it easier. However, it would still be helpful to get kernel sources released in a timely manner and encourage Devs to get this device / encourage Huawei to give devices to know quality developers.
In the meantime I would ask that people tweet or otherwise get in contact with Huawei to release kernel sources ASAP.

Expect nothing. Sell that crap and buy Nokia 3310. There is latest CM for it every day.
I'm not too concerned about a full custom ROM to be honest. Root is my main concern for minor tweaks and ad blocking etc

- How does PHH's builds differ usually from Stock EMUI ?
Hopefully there will be a kernel or two being developed with any luck ?

Any phone released with Android 8.0 or later (this will have 8.1), has to support treble as standard.
No idea what updates will be like but I hear that the bootloader will be unlockable and phh plans to support the P20 pro from a treble ROM perspective.
No idea about kernel sources being released by Huawei and therefore how long it might take for twrp and/or custom kernels to be built.

It never lack updates. Even mate 10 has plenty of updates.
What it lack is, an easy way to modify something.
Example,
I havent jump to this phone yet, because there's no root method available yet.
And android without root equal to : too many pain in the *ss, lol
Excuse me for being a paranoid Android, but with Huawei's past reputation on updates ..
Would it be possible for somebody to do the adb check and paste the results back here please

It supports (checked on p20 pro c432 dual sim)
So the question is.
Has anyone successfully flashed a treble ROM on the P20 Pro?
Did it everything work?
How did you do it?
I've flashed several via twrp, flash system image.
None worked.
I've read that the twrp versions we have are incapable of wiping completely.
Not only that but if you've modified the phone, IE: root etc it won't work.
Obviously you need to be able to flash the system IMG but by what method is it going to be successful?
Had tried los, dotos and cosmic all booted fine. Haven't had time to play with these roms though. I like the dotos design but I can't set-up fingerprint.
I flashed the images via fastboot.

Dev's Requested

Hi, does any Android developer own a Nokia 8, to start porting ROMs and developing suchs to it?
I believe we as a community can also provide founds for him/her/them if they need. Not much, but something.
I hope we can attract some devs for our terminal to rise !!! Lol
I already have some experience with creating custom ROMs and would like to make a LineageOS ROM for the Nokia 8 Only the problem is that I do not have a Nokia 8 to start with
I think the Nokia 8 will continue to struggle and attract Devs because of the lack of bootloader unlock.
Until the device can easily be unlocked any roms that are developed will only be useful to the small amount of users who have managed to get thier bootloader unlocked.
Until then, rather spending our time and effort attracting rom developers, we would be better off using that time and effort coordinating all the Nokia 8 users to apply pressure to HMD to provide an official bootloader unlock method.
An official version of TWRP has recently become available for our Nokia 8 and it is now time for a custom ROM. As a developer, I would like to bring the first ROM to the Nokia 8. I want to start with LineageOS and after with Resurrection Remix OS. How much I want to make these custom ROMs for you, just do not have Nokia 8 at my disposal. So that's my problem.

MIUI update UK model

Hi there. I have a Xiaomi Mi 8 (from Three) which I have currently got the region set to India, mainly so that I can use Face Unlock, Theme Store, etc.
What I'd like to know is, if I continue to use the Mi 8 under the India region, will I still get the MIUI 10 update when it's released, as its not set to UK?
Thank you for any help on this matter.
Unlock your BL, install MIUI EU and you can freely choose any themes you want without any stupid restriction from Xiaomi.

Thank you for your response, but I haven't a clue how to unlock the BL and where I'd get a non hacked version of MIUI EU from.
I'd probably end up bricking the phone. lol
I'm just worried that if I keep using it under a different region, I won't receive the update.

Usually updates are pushed to phones based on the build number. If yours is a UK variant then it'll have a UK variant build number (most likely). I wouldn't have thought the region setting you put in when first starting & setting up the phone would make any difference. But don't quote me on that...

I initially bought this phone as a work phone, but I actually enjoy using it more than my S8+, plus I've heard that MIUI 10 (plus Android Pie) is way better than MIUI 9.6.

I can confirm that MIUI 10 based on Pie is WAY better. Just the "OK Google" hotword detection to fix and it'll be pretty much perfect.
I'm in the UK, use mine with both my work and personal SIM in - I'm running the latest ROM from Xiaomi.eu (MIUI 10.2 - Weekly 8.11.23).
It's great.
Also have installed the custom GCam for it, which is superb! I use the Xiaomi cam for video and portrait mode and the Google Camera for everything else - night mode is seriously impressive.

I bought my daughter the Honor 10 for her last birthday. It's a great looking phone with a very good camera/cameras. The back of the Honor 10 (blue) has to be seen to be believed, it looks amazing.
I must admit, the Xiaomi does have the edge when it comes to the screen, but it is a close battle.
I do love the camera slightly more (it's very close) on the Xiaomi too, but everything just seems a little more stable with the Honor 10 and it's EMUI skin on Android 8. I've had a few older apps that have refused to run on the Xiaomi.
That will hopefully change on the next Xiaomi update.

As no one is not giving a answer, so I'll try to help you out.
It's no matter what you have chosen, if you have the stock recovery, you'll always receive OTA updates. You can not change the stock recovery without an unlocked bootloader which can be achieved by the official tool provided by Xiaomi, for further information, use Google.
Unlocked bootloader gives you access to all functions of your device, and this means that you can use even a Pixel device Android "mod", and it's the closest to the native Android.
If you are using IM apps too often, you'll notice that your notifications are not being delivered just in time. also, MIUI has tons of bloatwares and limitations that won't allow you to use your device freely, and appearantly Xiaomi is collecting some "not innocent" data from your phone, so you might want to consider your privacy. These are just my perspective as an user that was on Android for 7 years, I hope you will enjoy your device.
Have a great night.

Perhaps you will need to update it manually. Get the very first Android 9 release from official forums, and try to sideload it.
