Did you find any bugs on the AOSP ROM?, I'm thinking of flashing this now
Also, Did you tried the treble RR 6.0.0 ROM?

No bugs for now , all working fine.
I have not tried it yet.

I don't understand ..
I followed all the steps, but it installed stock EMUI 5 with Android 7..
Now, at boot, it says "Failed verification", and it won't let me install twrp, even if bootloader looks unlocked

This is the reason why i don't give support to rebranding . I tried so many times before getting the final result. Hope you will achieve that.

I successfully installed oreo on my device but now i have a problem. I can't install working gapps. I used amr64 8.0 opengapps but they crash when i try to put my google account so i can't use google play store or any other google service. I also tried GSM install but it's not working. how to fix?

Error 1 after reflashing ROM, can't (un)install Magisk

Hello, so I decided to reflash my ROM because I kept running into issues, and I didn't uninstall Magisk before doing so.
Then when I tried flashing Magisk it showed me error 1. Flashing the uninstaller gives the same error. Magisk Manager shows that it is not installed, Root Checker states that the device is unrooted, and so far the only app that mentioned my phone being rooted is LastPass.
What can I possibly do to reinstall Magisk so it's back on my device in its full grace?
I checked other posts and either they are not related to my problem or didn't help
Phone: Xiaomi Redmi Note 4 Snapdragon, Recovery: official TWRP non-treble, ROM: latest build of official AOSP Extended

Maybe try dirty flashing and flashing Magisk again?
Not Sally when Magisk is already installed, I can flash it again with no problem. Weird that you're having these issues. ?

Did you wipe everything? Wipe system and data before re flashing your rom.

@LennyTheCat To be absolutely sure what's going on you're going to have to provide the recovery log, saved after you've attempted you flash Magisk.

well, it has installed no problem, but then my phone got stuck in a bootloop after rebooting. I have to reflash everything now, will tell if it worked later

@Didgeridoohan when I install Magisk, the phone keeps running into bootloops. Clean install of the ROM and Gapps seems to work fine. Tried 16.0 and 16.4 packages

Well... You're using a Treble ROM, right? So I'm assuming you're using a Treble modified Magisk version (since there's no official Treble support in Magisk yet)... If not, I'm sure you can find the relevant information in your ROM's thread.
Always go to the source...

Guide to install Android 8.1 or 9 custom ROM?

The question speaks for itself,I cannot find really any accurate ways to get started because I once tried to install Oreo beta (before official was out) and flashed a Oreo recovery onto Nougat and bricked my phone,and the only way was to use DC Phoenix so for now I have kept my phone on EMUI 8 stock.
So if anyone can tell me the steps to install let's say an Android 8.1 Treble ROM or Android 9 when it gets good as a daily driver,I know that you need to do the following things:
-unlock the bootloader
-install a recovery
-flash a ROM through fastboot or through recovery and after that flash Gapps and a modded version of Magisk
That is pretty self explanatory,but I have seen like that you cannot use TWRP since there is a problem when wiping data and that you need to have Huawei stock recovery and some important things to consider since I see it is pretty easy to brick these phones if you don't follow instructions but since there isn't really clear instructions to do some of these things,I am asking here if anyone can explain to me.
And yes,I do have my bootloader unlock code since as I stated,I tried to do this before.

And if I have downloaded a zipped ROM instead of an GSI,I do the same steps but in TWRP I flash the ROM with the Gapps and Magisk,right?
Also,can I use NoCheckRecovery for Oreo when I need to wipe data instead of stock recovery since I think it would come in handy if I would need to re-flash something through that without Huawei checks and it seems to be easier to find?
And I flash the recoveries to recovery_ramdisk,just to be sure,I know some things did change with Oreo so I am asking?

Oh,I thought Pixel Experience ROM was meant to be installed through recovery,bloody hell pardon me.

Ok, it clearly says that that Rom is discontinued, read the last post.
Use a gsi from the treble enabled device development forum and flash it with fastboot (yesyou can use android pie 9.0 gsi's as well as long as they don't say sGSI on it.

Pie gsi
Hi all,
I have installed Pixel Experience (Oreo) gsi ROM no problem. But if I try to flash any Pie gsi ROM it just goes into a boot loop. I flash system via fastboot and seems OK. Reboot and it just boot loops a few times and goes to the recovery screen that prompts to download and install the standard system.
Has anybody come across this or have any suggestions. I have tried a few different Pie gsi ROMs and same thing happens.
Thanks
Mick

The official TWRP????
If not, please provide us the link of that TWRP which doesn't require this zip to be flashed after flashing stock ROM. I am planning to upgrade my device from Oreo to Pie, but I read somewhere that flashing decrypt.zip of Pie is erasing MAC IDs of wifi adapter. Can you please confirm that this zip is not erasing MAC ID of wifi adapter?

dang it, I got system corrupt notice after unlocked bootloader notice. Then it goes turn off.
After that I got that notice again while using pie firmware, any suggestions?

Should that be 'fastboot flash recovery' ??

Hey, I ran into the same problem today. If I find a solution, I'll let you know. I would be glad if you share too.

I tried again yesterday to install Pixel Experience, and again it just boot loops when booting into recovery mode. I've now reinstalled stock Miui and will try again.

There no recovery partition so it shouldn't. I'm on this ROM currently and have no problems with installation. The guide says that you need to be on latest global a11 miui (12.5.16.0.RKLMIXM). You didn't miss that?

I've no idea what version of the bootloader I'm on as getprop ro.bootloader returns 'unknown'
But, as I'm on "latest" v13 Miui, I suspect the bootloader is the wrong one. Do I have to downdate to 12.5 before installing PE?
Edit: I've downdated the device to 12.5 RKLMIXM and have flased the PE recovery image, all okay. It's now installing the PE zip, so fingers crossed that's it.
Edit edit: I have PE on my device! Thank you at @xuser_0 for highlighting were I'd gone wrong.
The key @JohanGriman appears to be to ensure your device is not on the latest Miui but the latest 12.5 version.

Is there any instructions on how to install Magisk on this? I've tried to usual ways (via apk and flashing .zip thru adb sideload) but it fails to repack the boot image. Will a manual patch of the boot image and reflash work?
Edit: I've been able to directly patch the PE recovery image (as used in the installation process) using the Magisk apk on my device. Can I now flash this patched image to the device?
I don't want to try it as other instructions I've found talk about a vbmeta image that needs to be flashed too, and I don't know if that's necesary.... and I don't want to trash my device again!

Just flash it but it will break safetynet. To fix safetynet enable Zygisk, add google play services to deny list and install shamiko.
