I cant do anything. It doesnt even show up. Right after device boots the popup says Pixel Setup has stoped working. After that i cant get it to setup. I rebooted my Phone but still no luck.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] LuK1337:
Yeah that looks worse than it normally is. You can always remove pixel SUW from /syetem lol.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] MikeYT22:
How can i do that? Im new to this stuff
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] LuK1337:
Eh, mount /system and use TWRP file explorer to remove it somewhere in /system/system/*app.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] MikeYT22:
Ok so when ill do that The pixel setup eont bother me and ilk be able to bot into the los16? Everything else will function correctly?
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] LuK1337:
Probably.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] MikeYT22:
Will give it a shot later. Atm im using Cypher os without a problem. The pixel setup worked, but only 1 thing bothers me that it doesnt have stock camera that los16 has.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] LuK1337:
Lineage doesn't ship with stock camera tho.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] MikeYT22:
Oh. It has less bugs tho. Will try and i hope my best i make it to boot succesfuly.

Does this ROM has screen record option like we see in EMUI 9.0
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] Digital Angel:
Hey Luk, Cheers for all your hardwork on making this rom available to the Masses. I got it flashed successfully and *almost* everything seems to be working perfectly, However the Pixel Navigation Gestures cause a reboot when attempting to enable them, even with the pixel launcher working just fine, and trying to watch videos also causes a reboot, Regardless of where I try to watch them, in youtube or just in the browser or facebook causes the phone to shut down and restart, do you know what might be causing this?

I am using the CLT-L29 Running on the EMUI 9.0 Firmware base. I have tried factory restores and even flashing the 2 of the older releases available but they all yield the same result, thanks for your time mate. If you need me to post any logs or files just let me know what you need and how to get them and I will be happy to provide
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] LJAM96:
Do you know the specific version of EMUI 9 you flashed over. When I initially had issues with things not working and the ROM rebooting it was due to the EMUI 9 base I flashed over.

Also "If it is a random reboot, grab /sys/fs/pstore/console-ramoops and /sys/fs/pstore/dmesg-ramoops-0."
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] Digital Angel:
Its flashed over 9.0.0.168(C636E2R1P12), and I will reflash the rom and get you that log file after forcing it to reboot. Thanks again
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] LJAM96:
I'm on a L09 device and flashed over .163 and never had random reboots and videos worked fine, except Netflix error codes but pretty sure that's a known issue
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] Digital Angel:
I am just first booting now, so I will get that log and maybe you may be able to see what is causing it, if not I will just stick with EMUI *Shudders* until further notice

---------- Post added 14th February 2019 at 12:01 AM ---------- Previous post was 13th February 2019 at 11:35 PM ----------

According to both ADB and the TWRP file explorer these files dont exist, I guess they have to be retrieved with root while the phone is booted?

[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] Digital Angel:
So for anyone who is having the Issues with media playback or Pill navigation causing a reboot, Roll back your EMUI Base to 9.0.159 (Below may work too, however I have no intention of testing it) I will post the links you need to roll back along with some bare bones instructions, however a decent knowledge of ADB commands will be required. Once you have rolled back go throught the process of flashing TWRP as per the original instructions and installing linage. I can not promise this will work for everyone, but it did work for me, tested on my CLT-L29

I take no responsibility if you mess this up and brick your device

Instructions

Huawei Firmware Database

Nocheck Recovery

NOTE: The nocheck recovery linked is for the BLK-LO4 model, Please ignore this as it is what is needed to do the roll back.

Big thanks for LuK for taking the time to help me get this issue sorted with me
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] LuK1337:
Builds starting from `lineage-16.0-20190217_125340-UNOFFICIAL-charlotte.zip` will abort the installation on firmware versions known to not boot when using my kernel. If any of you are on ~ unsupported ~ FW you're free to manually remove the assert and replace boot.img with stock kernel.img so that it'll boot up.

BTW the known working FW version that I can vouch for is `9.0.159`. I don't really recommend downgrading if you're on too new FW as you might end up bricking your device. Maybe soon I'll be allowing only new FW instead of old one but first I'll have to wait for Huawei to release kernel source code that'll allow me to do that.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] kzqg:
Hey, was really surprised to see this phone on the list for L16 and is the primary reason I'm considering buying one now.

Is it reasonable to assume I can buy a new one now and get everything setup with the aforementioned firmware and working right away (also assuming no user error)?

Also, any outlook on how long this phone might be supported? I realize this is a tough question given Huawei's uncertain kernel releases, but just wanted to get a general idea of how realistic it is for them to eventually release things and an idea of how dedicated [MENTION=5075128]LuK1337[/MENTION] is to the project. Would be glad to do my part to support it.

Thanks for any insight.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] josdehaes:
You can not unlock the bootloader anymore on any Huawei device. (Unless you buy second hand with already unlocked bootloader).
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] kzqg:
Even with a paid service? That's what I assumed I'd have to use.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] josdehaes:
That may work, no experience with that. I unlocked in June.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] SUPNYUS:
Some websites like FunkyHuawei or others can provide you bootloader codes :P for around 30$ I think, but I personally couldn't install this rom in my P20 Pro, my personal thought is that Huawei is the most complicated brand in term of installing firmwares, a real shame for me !
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] forever_lol:
Currently there's no, not even paid, unlock service available.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] kzqg:
Well that's a downer. Was hoping to escape the NSA-owned Qualcomm for the PRC-owned Huawei (only because I don't live in China), but I guess that settles that.

[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] Bryski:
Currently on the 5/12/18 build, to upgrade is it just a simple flash ROM and Gapps via TWRP over current version and reboot or do I need to flash stock recovery again then wipe in there and reboot?

Cheers
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] LuK1337:
You shouldn't need to wipe anything.

( don't wipe cache or anything like this either, wiping that stuff is a placebo anyway )
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] Bryski:
Cheers Luk.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] josdehaes:
I see the p20 Pro is now official. Can we dirty flash official builds on top of your unofficial builds?
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] silencer07:
Will this work on normal P20 devices?
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] LuK1337:
Who knows.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] Lineot:
Is there a way to allow to upgrade to the official builds without reinstalling?

IIRC when there was the CyanogenMod -> LineageOS transition there was a migration version which would support the transition by doing something like disabling key checking and updating the keys for app data.

Is something like that feasible?

EDIT: I found a zip called "lineage-migration-signed.zip" that might be able to accomplish that, but I have no idea if it would work in this case, and might very well screw up things severely

EDIT: that zip contains an updater binary shell scripts that updates /data/system/packages.xml by replacing "test" key strings with "release" key strings. I'm not sure if the appropriate keys are the same and if that procedure is still enough for LineageOS 16.0, but it seems quite promising. Any Android development expert willing to chime in?
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] macolinob:
LuK,

Have the procedures changed to install this image or are they the same as before? If I go to the LineageOS page and follow those instructions, it seems to not work. I mention this just to make sure others do not go down the wrong path.

Thank you,

Bret
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] LuK1337:
Define 'not work'.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] macolinob:
Sorry for not providing more detail. The instructions at this link https://wiki.lineageos.org/devices/charlotte/install

Do we follow the LineageOS instructions or yours?

Not work refers to what recovery to use and if you use TWRP and follow all the instructions the phone does not boot.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] LuK1337:
You still didn't provide more detail. Both instructions are pretty much the same although you may still need to wipe data with stock recovery instead of TWRP.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] lululala:
does the official build still require vendor base .159?
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] dferferfer:

[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] LuK1337:
If you look at history for that file you'll see what happened there.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] LJAM96:
There is something to see... IMS is listed there and thats the only real issue atm
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] Giraff3:
Installed fine with wiping using stock recovery. Seems to run great, no real bugs so far. Google's giving me a hard time backing app data up but that's probably a problem on my end.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] depl0y:
Hmm, I updated my TWRP to the latest official version. Sideloading the Lineage OS zip fails with an error 7.

"E3000: This package expects the value "_a" for "ro.boot.slot_suffix"; this has value "".

I wonder what is wrong here. I am on the latest EMUI version (9.0.0.195). It's a CLT-L29 C432
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] LuK1337:
Your firmware isn't supported. If you want to use LineageOS you can remove slot_suffix assert and disable boot.img flashing in updater-script but don't report any issues on official bug tracker and when reporting issues here please mention that you did that. Also you'll have to use MindTheGapps instead of OpenGapps because of that.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] depl0y:
Ok, would downgrading to an older version help? Or is it this exact type of P20 Pro that isn't supported?
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] LuK1337:
I don't know if you can downgrade.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] otonieru:
i think you can extract vendor, system and other image from the last supported EMUI (.168 probably) using update extractor and fastboot flash it prior to installing LOS. It should be fine since you wont need it to boot to EMUI anyway
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] lululala:
.168 causes random reboot.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] LuK1337:
That won't work. It's about the firmware itself, not like 'vendor' image.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] xchatter:
I also get the same and I am wondering what is not supported? The version is the recommended one - .195 and the model is L29 C432.....
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] LJAM96:
The firmware you are on is what is not supported. The recommended version is 9.0.0.159, you are on on 9.0.0.195
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] xchatter:
Ah...damn.... sorry then for the confusion. I will retry with proper version.

[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] josdehaes:

[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] Angelgmr:

No~
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] xchatter:
I couldn't downgrade to .159 so I will be on EMUI .195 for now.

It would be nice if the supported version is added in the first post.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] kzqg:
I'm not sure why this is an "official" release at all. It is limited to unlocked devices on an unlockable device and even then, on a very specific version of firmware. It's a nice thing to put on your résumé as a dev, but it's misleading to a lot of people who would otherwise love to use it.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] LuK1337:
Ask Huawei to release updated source code for the kernel and we can support latest FW. BTW like 2 pages ago I posted a workaround for too new FW, you can use that until we get new kernel.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] depl0y:
Yeah, thanks for that! I haven't had the time to test it out yet. But will probably get to it this weekend.

In the meanwhile, my phone got another update, running 9.0.0.203 now... dang it!
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] lululala:
would be nice if there is a GSI style system.img file so that we with the newer FW can skip the twrp and kernel steps altogether
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] LuK1337:
No, I don't find that worth it if one can just remove two lines from update-script.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] kzqg:
Yeah, I'll get right on that asking Huawei for anything. Their phones are locked down for a reason. That's why I was surprised this project was getting "official" recognition given it is a novelty with a very small audience with no room for growth. A feather in your cap but a disappointment to most everyone else.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] depl0y:
Just this line right?

getprop("ro.boot.slot_suffix") == "_a" || abort("E3000: This package expects the value "_a" for "ro.boot.slot_suffix"; this has value "" + getprop("ro.boot.slot_suffix") + "".");
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] LuK1337:
I said 'two lines'.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] depl0y:
Of course depends on the wrapping in your editor ;), but jokes aside.

Maybe enlighten me and tell me which one also? This is the last assert in there and mine fails on this.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] Vedrick:

You can upgrade or downgrade to any version you need. I had to downgrade to get this to install. Worked without issues. You can get pretty much and version from Here

There are instructions all over xda on how to do this.
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] otonieru:
you need to modify the updater-script in the zip, just like what the developer said,

you need to remove the line responsible for firmware version checking and boot.img flashing,

and, nobody can assure you hmthat everything will work,

btw, i wont suggest downgrade. this phone is pretty hard to unbricked in case things gone wrong,

if i were you, i would just stay on EMUI and update to latest version instead (.247)

i can't find much benefit of using LOS on this phone,

even if there's performance benefit it can't compensate the hassle you need in getting the camera fully works, losing the stereo speaker, and elses.

magisk and xposed installation also doesnt do any better on LOS. (and the only reason i use LOS on my any other phone is because i want to easily mod other stuff, like xposed and substratum, but that doesnt happen on this phone)

so yeah, its good for fun and experimentation,

but if you need stability, usability and fully functional phone, stay on EMUI
[Huawei P20 Pro ROMs, Kernels, Recoveries, & Other ] Manuele83:
