Custom Roms/LineageOS on SM-T505

[SanHelios]

Hello, everyone.
I noticed, there are many custom roms, but not that many for the SM-T505. Is it because it's newly released, or are there other reasons?

Yes, this is a new device and many people are probably waiting for the Black Friday/Cyber Monday deals to grab one. I just grabbed one for $150 on Amazon, a steal compared to something like a Fire tablet IMO. This is a low-end tablet, so there won't be as much focus on it as say a flagship phone. But thankfully it's already been unlocked and rooted, so the next step will be to get TWRP on it, and then custom ROM development can start to pick up on it. Don't expect any updates before the end of the year for custom ROMs though, it will likely take time to have TWRP up and running on it, but I am hopeful that we will see good things on this tablet in 2021

Without kernel sources it won't happen. See https://opensource.samsung.com/uploadSearch?searchValue=sm-t505 and https://opensource.samsung.com/uploadSearch?searchValue=sm-t500.

You can request them on that page. I did it a few times but no response so far.

Interesting... is it just me or is there no button to start an inquiry?

EDIT: Found it... just posted an Inquiry.

Just got an answer from Samsung, but don't get to excited. It was just an automated answer, that they received my inquiry. So stay tuned...

https://opensource.samsung.com/uploadSearch?searchValue=t500 gives you a 514mb file with kernel and vencor files.
Maybe both 505 and 500 are similiar enough to get you started

Sources are available: https://opensource.samsung.com/uploadSearch?searchValue=sm-t500

They include a toolchain in kernel tree, broken KConfigs and a lot of junk. I will try to clean a bit a mess and update a lean kernel tree to github

Will you also do a diff against the upstream version so we can see what they changed?

Sure, but I'm going to remove the toolchain from the kernel tree since the beginning. It takes About 1GB alone and I don't want to have it on git refs because it will still take a lot of space even if removed.

The rest of changes will be available on github.

It's been a long time, since i took up building custom roms and forgot about it for a while... if the kernel is cleansed from all the BS no one needs, that would be awesome.

There are a lot of small changes to comments and changes of 2 characters in a line. Wonder if they backported stuff there.

 

[SanHelios]

Kernel of the SM-T505 was just released...

If this is of any relevance, the download is 'just' 200MB... i wonder why.

 

[selemine]

The Platform Archive is mostly identical, just a few text files with notes and copyright were missing.
The Kernel Package as well, just small changes to netfilter and
a new defconfig file.

Defconfig for both devices also is more or less the same

gta4lwifi_eur_open_defconfig is missing one line compared to gta4l_eur_open_defconfig

CONFIG_SAMSUNG_FREECESS=y

Guess the difference comes from the toolchain mentioned above.

@paziusss
How far have you come?
Would be great if we had something clean to start a twrp and easier rooting
