Will it be easy to install custom ROMS on the P20 family?

Hi,
I've been using Nexus phones for years, and I'm thinking of buying a phone from the P20 family. I don't really like the version of Android that Huawei ships though, and I'd like to be able to install a stock ROM. I assume that this phone will have Treble support (since it shipped with Oreo) and that, because of that, it should be easy to install a custom ROM on it.
Is all of this correct? Will it be easy to install a custom ROM on these phones, or should I go for a different phone?

I'm also considering buying a P20 Lite tomorrow, how was custom ROMs development on P9 Lite and P10 Lite ?

Judging from the ROM development for the Mate 10 series and as it normally is for Huawei phones, it is not very likely that there will be that many ROMs specifically designed for the P20 phones.
However, installing Treble based ROMs should not be a problem at all. There are several such ROMs available, including AOSP, Lineage, Resurrection Remix, CarbonROM etc. The downsize is that these are often very generic ROMs and Huawei specific features may not be available. For example, third party camera apps often have inferior performance compared to the stock camera app. Sometimes these apps are ported over though.

Thanks for your answer!

So, we can take any Treble based ROM and installed it on any Treble enabled phone, and it will work? Don't specific phones need specific ROMs anymore?

Let's say I install an AOSP ROM and use Google Camera. Should I expect it to take bad pictures, or are you referring to something else when you say inferior performance?
Probably dumb questions, but I've been out of the ROM scene for years.

Yupp, that's pretty much the basic idea. Check out the following thread for more about project Treble.

The thing here is that the stock ROM may nevertheless contain vendor specific code which is not released and may have other proprietary conditions on it. The Google Camera may thus not return the same quality as the stock one. This has at least been the case for Huawei phones, although the stock camera app has been ported over (see the thread above).

I just unlocked the boot loader on my P20 Lite, now waiting patiently for a custom recovery

Custom ROMs are not very likely in Huawei devices

Hi all
Also been using Nexus for quite some time now, and bought a Huawei P20 lady week.
1. The camera is great
2. EMUI is not my cup of tea
My goal the coming weeks is to try to understand if it's likely to see a Treble ROM and if the camera app from EMUI/P20 can be ported.
Tldr; I want to keep the camera functionality but use stock android 8.x
Anyone find anything, please post
Peace ✌?

The camera app should be possible to port. It has been done in the past for both Kirin 960 and 970. Check this out for reference. In that thread the camera is based on the one from Mate 9 but in theory a newer one should be possible.

Taken down due to multiple force closes

Thanks

Can't see build for poco.
Was it taken down due bugs?

I was worried the dev pace was slow... seems like the only ROM you will ever need if you like MIUI

There's no firmware for poco F1 for EU.

u mean no china dev rom for poco?

It was taken down due to a huge amount of bugs.

Hi,
I must say that I am surprised no Custom ROM has showed so far.
Unfortunately, it seems the device doesn't attracct devs that much... Maybe just an impression and a lot of work going on under the hood.
Regards.

No, that's not it, exactly. The kernel source is incomplete, people are still trying to figure stuff out. But people ARE working on Kernel and LOS.
It's true we're not getting a huge tsunami of amazing dev's like the OnePlus 6, but it will happen soon. Also Pocophone may have promised to give phones out to some top XDA developers to help stimulate this.

Guys, how long has the phone been available to buy? Less than one month!

back again for download

does the previous bug has beeen resolved?

They have not made any rom for poco.but you still grab the rom for poco.just download the rom for mi8 and delete getprop line from first in updater script and flash in poco

Get many FC after a clean Flash for the new version on Xiaomi.eu..

Fix: To disable force close enable developer settings and scroll to bottom and disable "force-closed apps" to get rid of the annoying pop up msgs.
I really loved the ROM but many apps like playstore ,Google ,downloads, notes crash but the best part of the ROM is the touch is completely fixed ! Super snappy and latency feels really good. Hope they fix the force close issue soon cause i really cant wait to make this as my daily driver

Why MI MIX 3 have almost none Custom ROMS?

Guys,
Why does the MI MIX 3 have almost none working custom rom built for it?
The device is so good, i thought we would have lots of developers trying to build roms for it.
Any reason for this?

Probably because not many people own one?

It's not even been out half a year so what exactly are you expecting.
There also isn't much point when it's got treble support

I would like to see more development for this device. Xiaomi doesn't sell their devices in North America, which doesn't help. Sure, some of us import them, but the good developers tend to stick to commonly sold devices that are sold by just about every retailer and carrier. It definitely is an excellent device though and one I am glad I picked up.

If you google perseus lineageos a few interesting things come up like this: https://github.com/LineageOS/android_device_xiaomi_perseus
Does this mean we may get lineage at some point?

I think more developers will working on custom roms for this device when this device will be available officially in India and maybe when our device will get bootable LineageOS builds (I saw some commits for Mix 3 but I dont know if you can build bootable rom from these sources, I am not dev https://review.lineageos.org/q/perseus ). Bootable Lineageos = "stable" device tree as base for other roms.
At least we can use GSI roms

Redmi 7 ROM issue

I don't know what happened to the developers. Especially about the Redmi 7. This device has been released for 6-7 months but no official ROM has been seen so far. All that is getting unofficial or GSI ROM. Can't we get the official ROM?

Usually, the way it works is, only devices that developers actually own get custom ROMs. If there are no ROMs for your device it is probably because there are no developers that own a device like yours.
You'll probably get a custom ROM faster if you learn to build one yourself or if you buy another device like yours and donate it to a developer to build your ROM and pay the developer to build the ROM.
Other than that, you're on your own until a developer decides to buy a device like yours and build ROMs for it.(if a developer ever chooses a device like yours)

Question Custom ROM for 12s Ultra?

Went from Mi 11 Ultra to this, and I've noticed that the custom scene for the 12s is pretty lacking aside from the EU ROM. Just curious what it'd take to get an Elixir or even an Evolution ROM these parts.

12s pro and im waiting like you
May be this 12s series didnt go global so it didnt get more attention

...and for the record, anytime anyone spends time making a custom ROM I'm extremely respectful for that (I've been using customs since Windows Mobile 6.1). In no way am I dragging them nor implying that we're owed this. Again, I just love customs and was simply curious with this.

I have heard on the telegram chanel of 12s ultra, than some people are using the rom mi pro, but I haven't find channel or source (or only for chinese users?) and which seems to be a paid rom.
I have also trying to flash the simplicity rom, but I have a soft brick even if I pass the boot but my phone show only 0% of battery and apps were not working with only access to fastboot.
So I solve it by flashing a fastboot mui 14 rom via my pc.
Anyone have tested the mui pro or the simplicity rom ?

Just some custom miui rom. And if it still miui, i recommend u to stick with xiaomi.eu
Waiting for aosp rom, it will be so much better

It won't have it since Xiaomi didn't released the source Kernel.
