Do other rom projects have Device Support Requirements like LineageOS? - General Questions and Answers

LineageOS has Device Support Requirements to make sure hardware works well. This is one of the reasons why I daily drive LineageOS.

I wonder if other rom projects have such strict requirements.

Essential prerequisites for X2 Android development [Crowdsourcing]

There is 3 packages needed for any device for an original Android development:
Android source tree, preferably the original as with OEM devices but CyanogenMod or independent ports are enough too. Aka device
Kernel sources for the device. Aka kernel
Vendor proprietary drivers, which make the GPU and various sensors work. If not explicitly available for download they need to be extracted from a running device. Aka vendor
If these three packages are all available, making new roms will be easy for developers. Please co-operate to gather all of them here to be a resource for android developers.
If we could achieve this goal, I would port the Ubuntu OS for Nokia X2 and share it here with you
====
Progress:
Android source tree
No known instant or effort.
Can anyone contact to Microsoft mobile and get the Android source tree for Nokia X2 and upload it to Github?
Kernel sources
here is kernel source code for Nokia RM-1013 2.0.0.11: https://github.com/danialbehzadi/Nokia-RM-1013-2.0.0.11
Due to Microsoft mobile statement, there is no difference in kernel between 2.0.0.11 and 2.1.0.13.
DONE! :good:
Proprietary drivers
Thanks to T4ufik_Hidayat, Here is vendor packages: https://github.com/cm-nokia-x2/proprietary_vendor_nokia_ara
DONE! :good:
Nice effort
You are our only hope
As we have no real devs for this device and the device wasn't released globally, u r our only hope. I request u to build the kernel with device tree that we need so much to port any real android rom like AOSP , please. Frozentears was working on that, You can contact him as well.
Again, I request you, please make us a custom kernel so that we noobs can start porting KitKat/Lollipop for our beloved X2DS, u r our only hope because we see no other developer here for this device.

Here is for proprietary https://github.com/cm-nokia-x2/proprietary_vendor_nokia_ara
for Android source tree, try to use CyanogenMod.
maybe you can help people to make the complete rebuild of CyanogenMod with full fixed from bugs

Xperia 10 Plus added to Sony's Open Devices program

This means that developers are able to build and flash their own version of Android Pie on these devices.
The Open Devices program is our way to provide access and tools to build and test your custom software on a range of Sony devices. You can access all the resources you need through our Open Devices page on Developer World. We value our open source community and welcome you to participate in our projects via GitHub. Feel free to provide feedback on further resources you may need and where we can improve.
To get started on how to build AOSP for your device, use our build guides for instructions. Please note that this software is meant for developers and can be unstable due to its early stage. As part of our Open Devices program, the project for the Xperia 10 Plus are now available via GitHub where you can contribute and take part in our open source community.

Great stuff

List with devices having official releases of TWRP, LineageOS and other roms

Dear community, I think this list is the first of its kind.
Purpose
The main purpose of the whole project is to help newcomers find the relevant TWRP and Roms for their devices and ultimately make the installation process as easy as possible. This list also serves the purpose of giving an overview of devices which can run custom android roms for people who do not have such a device yet and would like to buy one but don't know which ones to choose from.
Goal
Its goal is to contain as many devices (with name, model name and codename) as possible which also have official releases of TWRP, LineageOS, Resurrection Remix, Omnirom or Carbonrom. The list also contains some working TWRP builds and roms that I saved to a personal archive some time along the last years - mainly for older devices without newer roms and for good roms that just did not made it to an official release.
The Free-Droid project
The creation and continuous update of this list is tied to the Free-Droid project, mainly because it is scraped and put together by the same ruby code that is used inside the Free-Droid One-Click Rom Installation Assistant.
Why only these chosen roms? Can another rom be added?
The choice of roms showing in the list is constrained by these factors:
free and open source (no google apps included)
The website with the official releases can be scraped (programmatically read and evaluated) with ruby code down to the individual download links for the roms
(Preferred) The rom zips have signature spoofing support or are patchable with the NanoDroid patcher
A lot of roms fail at one of these constraints. I tried to add crDroid, but their website is pure javascript and can't be scraped easily. AospExtended was added by using the OTA API, but it turned out that the API server is way too unreliable. What might be possible and get added are mokee and /e/.
Updates
The list is automatically updated weekly and should always point to the latest available roms.

Question bootloader unlocked?

Somebody managed to flash a generic system image. No idea whether the device is based on qualcomm or hisilicon. And seems that it isn't repeatable arbitrarily due to potential efuse writing.
Yes,it's a Huawei P50 prototype
And it can run Windows 11

General [info] Xiaomi 13 (fuxi) Open Source Kernel and Lineage Device Tree

Hi all,
For those of you, like me, who are interested in learning more about developing for custom ROMs, the following links will be helpful for finding .
First is the inclusive list of open source kernel releases by Xiaomi: https://github.com/MiCode/Xiaomi_Kernel_OpenSource
At the bottom of said list is the Xiaomi 13 (fuxi).
Second is the device tree (based on Lineage OS and said to be WIP) by YuKongA: https://github.com/YuKongA/device_xiaomi_fuxi
What is the primary difference between official xiaomi 13's device tree https://github.com/MiCode/kernel_devicetree/tree/fuxi-t-oss and https://github.com/YuKongA/device_xiaomi_fuxi ?
YuKongA's contribution is for Lineage OS, or instead of MIUI it's AOSP. I think.
To give additional information, the Lineage-derived device tree likely originates from: https://github.com/imasaru/android_device_tree_template
Also, the kernel includes a lot of stuff for the hardware and is accompanied by a kernel device tree, which is a kind of 'table of contents' (unless I'm mistaken about the analogy).
"The 'Open Firmware Device Tree', or simply Devicetree (DT), is a data structure and language for describing hardware."
Linux and the Devicetree — The Linux Kernel documentation
I imagine a lot of compatibility issues are lining up the system image and the kernel+device tree.
...
(At this point, I'm really just spouting off some things as I'm learning, so feel free to correct or ignore me as I'm going along!)
