How to become Maintainer for Lineage OS?

Hello,
I want to become maintainer for Lineage OS for specific device (I will buy the device to maintain).
Could someone plz explain me the process of becoming the maintainer and pre-requisites for it?
I had a look at teamoctos/join-our-team/ but it will be helpful if someone explains all those steps in it.

Thanks

I'm not sure about this but however:
First of all you will have to build device tree for that device (I guess that device isn't supported at the moment, if is than you can contribute to that repo on github via pull requests and wait for them to approve change) and that device tree works without lethal bugs. Also you'll need kernel that won't make you much troubles because manufacturer probably published sources (they had to). And when you make it work than you can try to conntact them about joining team, if they accept new devs, because I read somwhere about how to make CM support device officialy they mention only they support devices they own, they not mention anything about joining team if I remember well. It's best that you conntact them and ask I'm sure there is way for that.

Unless a specific thread states otherwise (which will provide you with the individual or location to do so), the XDA Forums isn't where you request this.
Regarding the Official LineageOS, though, the XDA Forums isn't where you request this either, here's the only location (at this time) to where you can find what you're looking for.
1) Go to the following link:
http://wiki.lineageos.org/faq.html
2) Scroll down to the following question (without quotes):
"My device is not officially supported, but I’d really like to give LineageOS a try. Can you support my device?"
3) It is there that you'll find the information you're looking for as well as the E-Mail address to where you can send them the information.
Good Luck!

General Color OS on Non-Chinese (LE21X0) variant 9R/9/9Pro

I contacted the staff of OnePlus to inquire about this question. They said that the degraded conversion package is only for CN variant. They don't think it's a problem and won't solve it.
So I'm trying to port it into the non Chinese variant of the device, because I don't have enough money to buy the EU variant OnePlus 9 (I need it to study the difference between the Non-CN variant and the Chinese variant, because the European variant is cheaper, so I plan to buy this variant), the research progress will be very slow.
At present, I have designed three plans:
1. Make changes to the firmware on the device to fit the degraded package.
2. Using the MsmDownloadTool of ColorOS to flash. (I'm responsible for remote operation, so it can't be used as a long-term solution)
3. Extract the ColorOS firmware out of the raw image to flash. (may die in partition problems, and should not apply to 9R)
4. (This plan has been abandoned, because the signature can not be forged, and it is too troublesome to adapt to each different model) Make changes to the degraded package to adapt to the hardware of different regions.
Due to the above reasons, I can't test and implement plan 1 and 3. I have found a brave 9 Pro India user to test plan 2 and wait for the good news.
I'm going to launch crowdfunding in the near future. If you have extra funds and want to try ColorOS, please support me.
If you want to provide the device for testing (it doesn't necessarily succeed and the device will not be returned regardless of the results), you can also contact me.
If you want to apply for the remote test scheme, I will be happy to accept it. However, please note that no matter what the result is, I am not responsible for any impact of the remote test on your device, and the device may lose its warranty; Since I am still a high school student, I will only provide remote testing service in my spare time (China, GMT+8, Asia/Shanghai).

I put the package in the update channel. It seems to apply only to LE2120 CN variant. That's why I need a EU 9 to study the differences

It's not msm tool for unbrick. It's just downgrade package.

On your telegram channel you only have the downgrade package. In your OP you suggest you have the MsmDownloadTool for ColorOS. Would you be able to publish that?

Turn AT&T into a the global variant

After a bit of experimenting (and a lot of fights with the bootloader since it always decided to relock itself preventing me from simply using fastboot) I managed to get the global fw to run on an AT&T device.
TLDR: You can just dd the global partitions while rooted and then restore through adb sideload.
Guide: https://github.com/filiphsandstrom/surface-duo

quick question.
for step number 2 "Use payload_dumper from the rooting guide to extract the partition images", am i extracting the partition images from the Global version or the AT&T version?

So does this mean anyone using this firmware has sim unlock? I saw on the GitHub you mentioned it works on another network outside of AT&T

The global version. The script will then dd those to the correct place

I had great success with this and have relocked the bootloader as a normal duo device thanks, if anyone has any questions about how i managed it let me know. Thanks so much @filfat

I just wanted to thank the OP for making this process easy with the instructions and for the new life given to this phone. Now that the phone has been converted to the global version what happens if another update comes down the pipe? Do we flash the global version, at&t version or sit tight and await further instructions ?

@Draco32 or @filfat
First:
1|duo:/data/local/tmp # chmod +x globalify.sh && ./globalify.sh;
./globalify.sh[7]: syntax error: unexpected 'newline'

Why error?

I have the same question when the duo announcing the newest OTA. The at&t Duo which turned to a global variant can update by OTA or must flash the new images by this method.

copy and paste what commands exactly? are you saying do each .img 1 by 1? or something else? i copy/paste the commands from the github but i got stuck at 47% same as the other guy.

I just received a OTA update and it failed. I followed this method to unlock my At&t version.
How do I go about updating, but more importantly which OTA should I be looking to flash, At&t or Global?

run sideload to 94% already but still locked sim. how to know if esim is working?

I make no promises this will work successfully on your device and take no responsibility for whatever may happen. My Duo (I want in on that 3/ds and Windows 11 action) is in the mail and I'm going to be trying this myself.

A bit of googling found the repo https://github.com/kenpc-git/surface-duo
I wonder if updates worked after this? would this be a way for AT&T users to get the latest 12L update?
Anyone who used this and is running it still? Any issues?

Worked for me, flashed it to global and it automatically upgraded to 12L

When I try the adb sideload I have the following message:
------------------
E:
(adbd status 5)
Install from ADB completed with status 1.
Installation aborted.

Can someone help on this ? Thank you.

Gen5W for HKMC root access

Hello guys! I am a bit tired today to explain all the details, we will be writing a better post soon. But for now this will have to suffice.
TL; DR;
We are going public on how to hack the headunit for HKMC vehicles. This applies to pretty much all Gen5W models, requires no soldering, and yeah, its fun I guess.
This is pretty much for devs tho, so if you expect to run youtube with this today, sorry, but not yet. It will be possible tho, but so far we were focused on getting the access.
What is all this about?​This project aims to give users ownership of the headunit on their cars. You paid for your car, you own it. That includes its computers. With this project we aim to provide you with the ability to extend your stock functionality on certain korean models.
We are not on this for commercial gain, however, you can use whatever we've learnt so far to build and sell CFW if you wish, that is up to you. I only ask that you contribute back and share your findings. Basically, open source mentality between us here. We all want the same at the end of the day, which is completely owning our cars and the systems on it.
We do not sell the access to the hack.
We do not sell the tools to get access to the system.
We share our knowledge.
You can:
Build and sell your CFW using the tools / knowledge that comes from collaborating. (Please, strongly consider sharing how things are done so we can attract more developers when we decide to go "public")
Also, consider safety first. Let's try not allow non-technical people to drive while watching netflix. But this is completely to your discretion.

Just to be clear, did you extract a key already from the unit? I haven’t included any decryption binary nor key on the gitlab, the files you see there (DecryptToPIPE & the .DER file) are just placeholders, read te contents of those files for details

Not entirely sure. Nobody has yet found the key besides me (or haven’t spoken up) so I can’t compare if keys are unique across units. But the key in your unit will be able to decrypt all gen5w updates up to date. To get the key you don’t need to dump the whole software, it’s enough to just rename a program in the unit, put a shell script where that program was , once called, get the args passed to the script (you’ll have one of the args as a path) copy the content of that path to your usb and then lastly call the original program so the process works as expected for the headunit. (Man in the middle).
The reason we don’t share the key (or the DecryptToPIPE software) it’s because that might be copyrighted material, and we are avoiding any copyright infringement.

Hello guys, I want to tell you my story, and I need a little help from you also :
My car : Kia Sportage QLE Gen5 navi, updated to sw : 211029 fw : 210930
After update , no way to find pin for engineering mode, only dealer mode with pin 2400 and 7,3,1 volume combination. But with navigation hack, showed in this thread I managed to enter engineering, and managed to make adb to work on ethernet, but the only way to do adb to work was by installing an USB to Ethernet converter into USB, connect and ethernet cable between converter and my laptop. Don't know for sure if it is necessary or not, but after installing everything ( usb, cable, etc) I made an Reset to factory . Connected the wifi of unit and phone to house router, and finally was able to install apps with Easy fire tools.
I manage to install boot hack and now when I press 2 times on SETUP is going to engineering menu, and from there I can access all other applications that I have installed ( file manager, soundabout).
So I hope someone else who wants , can now get adb to work and install what he wants.
Now I want to ask the ones who already managed to install apps, if they can help my with some apps that are tested and working OK : I need an IPTV software, I installed GSE IPTV, with was working ok before upgrade, but now it does not start playing, only loads m3u list, you can select channel, but .. not start. Youtube working has anyone? I installed an older version, but it say it can not work without google services. And last, is there a way to add shortcuts to apps in oem menu? or a way to quick access them? or something like task manager? not to be forced every time to go to all apps and start app from there?
Thank you, end if someone needs more help with adb to work, and did not understood complete what I said, please fell free to ask, if I can I help with pleasure.

I downloaded the my20 update for xceed, but the installation checks update files section gives an error at %30 and I still could not update. Can you help me?

New updates on this guys ? Is this project abandoned ?

Galaxy Watch R815F - need help with region change

Hello guys,
I have seen a lot of topics on this subject and honestly i don`t know were to start. Yes, i am a old guy and total noob on flashing roms and so on...
Recently my carrier in RO, Vodafone has implemented an option that allows using ESIM on other devices. that being said i proceed activation the option and trying to make my trusty companion R815F to work. Went to Samsung care and they told me that the watch is using an UK region code and will not work with my RO carrier. ( bought the watch also in Romania but .. well apparently it was destinate for other country code)
My watch :
Model number: SM-R815F
Serial: RFAN31FSY2E
SW version: R815FXXU1HVG1 SM-R815FZKABTU
Tizen version: 5.5.0.2
What have i done till now:
- developer mode on
-debug mode on
-download ODIN
-download SDK
-connected to watch via CMD
-tried launch_app csc-manager.csc-pre-configuration - getting an error " internal/external comand ... etc"
Now, being a total noob i don`t understand the next steps:
- do i need combination file and firmware rom for changing the region ?
- do i need to downgrade to tizen 4 in order to do something ? ( how to ?)
- where to find stock firmware - which one to choose because i found something that is paid and i don't want to waste money on something that is not working
Please if anybody can help me or give me a hint were to start it will be much appreciated.
Thank you,
A

Code:
COMBINATION-FT40_R815FXXU1ATA1.tar.md5
Risk because untested...
ATA1 could be dangerous outdated...
No idea from where to download this file... for free...
I will do some search...
Best Regards

Thanks for the feedback. i will wait for your findings.

Hi,
Sorry for being so impatient But did you find something?
Thank you,
A

Sorry.
I have nearly nothing on my HDDs... only really old files.
My suggestion for you.
Search for Firmware Files in Internet...
You can post here what you found. BEFORE you try,,,
For instance start with this file:
Code:
COMBINATION-FT40_R815FXXU1ATA1.tar.md5
Sorry I have my own problems and limited time and energy...
So you at your own...
Good Luck.
Best Regards

I finally made it work thank to user: Jon199102 on Reddit.
He point me to a "hidden feature" of Galaxy Wearables - hidden menu to activate QR code searching/integrating -> auto or manually set up the ESIM. after enabling it i scan my qr code from VDF Ro and 10 minutes later everything was working
I don't really know if it is allowed to post the link to Reddit but here it goes :
