My question is really simple: How can I make an unofficial port of LineageOS? I've read this, which is based on an article from the (now death) CM Wiki, but some files (e.g. the mkvendor.sh script) are in older CM repos/branches. According to what I've read, there's not a full guide explaining the porting process since every device has its own tweaks (I imagine that it's due to ARM's nature)
What I want to do: Port LineageOS (the latest version) to the Samsung Galaxy Ace 4 Neo SM-G136ML (codenamed vivalto3mve3gltn). However there's not a LOS port at the latest version for a similar device which I could fork, so this would be "from scratch" in some way. I've seen Lineage's android repository at github but idk what are those xml files (they are definitively not the source code of a whole OS) EDIT: I realized that I had to clone it with `repo init`
What I've done so far: Documented myself as much as I could, read about how to get the vendor files, firmwares, kernel sources (in fact I requested the kernel source code for the device to the vendor), build.prop, recovery.fstab, and recovery/boot images.
My skills: I have a lot of experience with the GNU/Linux OS and I know some Linux kernel hacking, in fact I'm used to compile kernels for the x86_64, i686 and armv7h arch'es (not the vanilla kernel itself, but the Linux-libre kernel, which is basically vanilla but without binary blobs) and also patch them, and test them, etc. Besides kernel-stuff, I know shell scripting, advanced use of git (git clone, commit, add, push, remote, fetch, diff, apply, and more), use Heimdall, install custom recoveries and ROMs, and some advanced (non-noob ) Android hacking (Idk Java, C nor C++, however)
I know that here at XDA we've very talented developers who have experience with this, and much more. The only thing I need is some guidance to help me in my way to contribute the FLOSS community, I say this because when I asked in the LineageOS IRC channel if there was an official or well documented and updated guide, step-by-step, tutorial to port LOS that I could follow, someone answered me "it's impossible to have something like this", but I believe that there's ppl here who can demonstrate me the opposite
Thanks in advance
(...) I requested the kernel source code for the device to the vendor

Magisk Patched Unofficial GrapheneOS for the Pixel 6 / 6 Pro (oriole/raven)
This ROM will allow you to lock the boot loader. Do not ever disable the OEM unlocking checkbox when using a locked bootloader with root.
This is critically important. With root access, it is possible to corrupt the running system, for example by zeroing out the boot partition.
In this scenario, if the checkbox is turned off, both the OS and recovery mode will be made unbootable and fastboot flashing unlock will not be allowed.
This effectively renders the device hard bricked.
I am not responsible for any harm you may do to your device, follow at your own risk etc etc, Rooting your device can potentially introduce security flaws, I am not claiming this to be secure. If you would like to have more security and peace of mind then I highly recommend you follow This Guide to build this rom using your own encryption keys.
GrapheneOS is a privacy and security focused mobile OS with Android app compatibility developed as a non-profit open source project. It's focused on the research and development of privacy and security technology including substantial improvements to sandboxing, exploit mitigations and the permission model. It was founded in 2014 and was formerly known as CopperheadOS.
The features page provides an overview of the substantial privacy and security improvements added by GrapheneOS to the Android Open Source Project (AOSP). Many of the past features were contributed to AOSP, Linux and other projects to improve privacy and security for billions of users so they're no longer listed on the features page.
More info:
Official releases are available on the releases page (Not Magisk Patched) and installation instructions are on the install page.
GrapheneOS also develops various apps and services with a focus on privacy and security. Vanadium is a hardened variant of the Chromium browser and WebView specifically built for GrapheneOS. GrapheneOS also includes our minimal security-focused PDF Viewer, our hardware-based Auditor app / attestation service providing local and remote verification of devices, our modern privacy / security focused camera app, and the externally developed Seedvault encrypted backup which was initially developed for inclusion in GrapheneOS.
No Google apps or services​GrapheneOS will never include either Google Play services or another implementation of Google services like microG. It's possible to install Play services as a set of fully sandboxed apps without special privileges via our sandboxed Google Play compatibility layer. See the FAQ section for more details on our plans for filling in the gaps from not shipping Play services and Google apps.
Installation Instructions: Fashing-factory-image
Locking the bootloader is Optional but does increase the device security Locking-the-bootloader
Update Instructions: simply follow these instructions Updates-sideloading to sideload the latest patched OTA update package (You can update from any previous version if using full ota update)

Builds for Pixel 6 Pro (Raven)
Always do a backup of your data before flashing any updates, just in case.
I make no promises that this works or that I will provide regular updates. I will attempt to provide updates when they are available and I have time, you may have issues with this rom, you could lose your data or brick your device (although it's very unlikely if you follow the instructions and use common sense)
#reserved
Thanks for this!

does the full system install include the android 13 boot loader? if someone was still on A12 should they do a full oem update first?

I think you should upgrade to stock android 13 first just to be safe
brilliant thanks!! can i ask a reallly random stupid question please. if i have a stock pixel 6 rom, can i just run the ota update to keep present apps/data in place and to upgrade it to graphene or would that break my phone if not already running graphene?

You must install Graphene OS first, and if you want to lock the bootloader then you will need to erase your data anyway
People from GrapheneOS will permanently suspend your account on their forums for simply telling people that it is in fact possible to ROOT Graphene and Lock the Bootloder
They like to LIE to people and tell them it's impossible, while preventing anyone from contradicting them
I flashed the oriole image flawlessy, everythings seems to be fine except for the magisk manager that keeps crashing. I need to do something in order to make it works?
Edit: my bad, i was installing a super old version of magisk Sorry.
Thank you so much for you hard work
i cant find any information if its possbile to use google pay and android auto again with a rooted grapheneos and working magisk modul.
i like graphene and the features but it sucks to use an iphone for my car and cant use my galaxy watch for paying something :/
any1 got an idea or is the only possibility to flash stock google for both apps

You cannot use google pay with official Graphene, I mean it works with loyalty cards but not NFC payment cards
So you should not expect it to work with a magisk patched Graphene, maybe you can find some magisk module and a configuration to get safety net passing and google pay working. But I am not aware of anything that works with Graphene
Why so much headache as go trough build for such simple task as resign especially for Graphene? Just get ota, follow instruction in readme.txt avbroot and that it.
I understand if you do any changes to source (patches, unneeded apps, own apps, implement of root). But just for locked bootloader? Bootloader locked or not doing it job.
If you loose and somebody stole your device how locked bootloader helps? Get your data from recovery (it stock, not custom) over adb shell if you use pass not possible. Find device or location not on graphene build. You can't pass Safetycheck or use phone for contactless payments (NFC)
So all that wind just not allow to thief reflash and use device?

If you think it's too much headache, that's fine, it's not for you.
I prefer to build it from source myself using my own keys for the whole process, it may be possible as you say just to patch the provided ota with avbroot, but I haven't tested this and don't have any plans to
I don't want to argue about the potential security benefits or downsides, If you don't believe it's secure and you don't feel safe using it then just don't use it. I like my data being secure and not easily accessible, regular backups are important
You can't pass safetynet or use google pay for contactless payments on official graphene, so please take it up with them to fix that as rooting it isn't going to make you more likely to pass safetynet
The thief can always just reflash and use the device unless you disable OEM unlocking in the developer settings
But you should not do this, because if something happened and your phone started to boot loop or something then there would be no way to fix it and you will brick your device, but at least your data will be safe if you had the bootloader locked

Read one more time my comment
I'm not said that I will or plan to use your guide to build. I said that it to much work for average person.
I saw your post where you clearly state that you wanna locked bootloader. I pointed to easiest way to do that. Don't like it? Do what you like.
For patching ota by using avbroot. I did it and tested on my own pixels(6a,2 -6, not pro) and not pushing you to do that. As all here I wanna show people another option.
I don't need rom signed you or any one else. It personal rom and I do not have time and willing to inspect it. For me enough that I trust graphene team! I already build rom for my self with implemented of root, patching some graphene code, remove some apks and replaced it with mine and settings that I need. Of cause I sign but that rom it for me and my family not for public. So no any need in secondhand roms.
I did't tell that you responcible for NFC, Saftynet pass just wanna point out that locking bootloader not helps with these issue.Not expect you fix that. You said that you didn't touch code. It's Graphene and it on their side. I used Graphene long enough to know advantages and disadvantages.
And I as you don't intend to start security discussion here or with someone else. Don't worry and have a good day!

1.I already know this, I thought this would be obvious. I think using Graphene OS at all is too much for the average person, the average person will just use their phone as it comes and never put a custom rom onto it. This was never intended for the average person.
2. I appreciate that there is an easier way to do it, But I already said I was going to do what I like instead.
3. I appreciate that you have tested this works, I will likely update the guide I have created with this information for people who don't want to build it from source but would also prefer to patch official builds with magisk themselves
4. I do highly recommend everyone does build it themself, I think you should not rely on and trust graphene to always provide updates that have not been modified in some malicious way, it's always possible they could get hacked and an update build could be silently replaced with a malicious version
5. Locking the bootloader has nothing to do with safetynet for me, It's more about the other protections that locking the bootloader enables, like making it much harder for someone to be able to access my data or use the phone without erasing the data
Thankfully there is several banking apps which work and even let you use NFC for payments, while you do not pass safetynet
6. I appreciate it, thank you. I hope you have a good day also.

I spent half of my week following your guide because with my old ass I7-3770K running Debian within VMware takes days since I didn't know there was another way. The main building part (m target-files-package took 6,5 hours to complete) Reading what boom15 said I'd be very happy if I never had to go down this route ever again.
Thank both of you gentlemen for spreading information about this, I wound't be able to figure it out by myself.
I guess I only have to download the OTA from grapheneos.org/releases and follow avbroot's readme, right? (I feel like a retard right now for wasting that much time setting up my VM, it running out of disk space, reinstalling it, etc.. )

I do completely understand and sympathize, I have already updated the guide with this simple method of patching graphene for those who are unable to or don't want to build it from source themselves
I think you have gained some valuable experience and knowledge though which will likely help you in the future with other endeavors.
At least you didn't spend a good couple of weeks trying to patch graphene with magisk manually before I even discovered AVBRoot was a thing, so glad that exists

I understand your side too, my end goal would be using only self built opensource software on every device I have, but you gotta start somewhere, right? Maybe once I'll have nothing better to spend money on I'll build myself a newer pc and dual boot linux so it doesn't take ages to build graphene.
I'm all about doing new things, getting experience and knowledge, so I'm not even mad, but just feel relieved that I'll be able to update it easily. Atleast now I'm getting familiar with Debian, which will come in handy when I'll get myself to continue setting up my VPS, so I can selfhost everything I need..
Well I didn't try that, mainly because I'm curious if I'll be able to use my banking app if I root my phone and lock the bootloader, since that sucker won't even let me use contactless payment with a stock os combined with an unlocked bootloader.
