Lineageos 16 with device-specific files from 14.1? - LineageOS Questions & Answers

I have an old Samsung galaxy tab S sm-t805 (chagalllte) which is still working fine.
Lineageos abandoned the chagalllte in release 15, and only supported the chagallwifi version.
I'd like to update it anyway (yes, I know this operation is not supported)
In the build-yourself process, I saw it needs device-specific files. Can I use them from a 14.1 release (eventually with checking new kernel options) to install the 16 version? Or are chances too high to brick the device?

Android 9 Pie / LOS 16?

Any chance we'll see LOS 16 or other ASOP Pie 9 ports to Galaxy Tab S? I have unofficial LOS 16 on my 2013 Nexus 7 tablet and it works quite well.
To get Pie, someone (read - me) should invest 2-3 months of spare time to make it production. The team is basically silent, and I am more concerned about my paid job and keeping N security up-to-date. I am also building 16.0 internally but it is not even alpha for me (like, not completing boot on chagalllte)

Anyway to help out ?
I've just put Exynos5420 LineageOS 14.1 vanilla onto a tablet.
Also just setup a build environment, grabbed the Exynos5420 git repo's source code and built successfully the cm-14.1 branch.

Difference between klimtdcm and klimtlte

Does anyone know what the difference between the two is? I stumbled upon kyasu's Github Page: https://github.com/kyasu/android_device_samsung_klimtdcm
There is already a LineageOS 16 out which is newer than the current for the SM-T705 which I have (klimtlte) so I am wondering if I could go along with the one from kyasu despite being klimtdcm....
I'm kinda looking for the same information. I have klimtwifi (T-700), which is still back on 14.1. I know I can't just install the klimtdcm images, but I'm hoping I can at least build my own. I just started getting set up for it this morning, so I don't know how it'll go. If you find out anything, I'd be interested to hear.
Thanks!
klimtdcm = Qualcomm Snapdragon
klimtlte = Samsung Exynos
So no, you can not use nor adapt it to work on you Samsung Exynos device
What about SM-t700 klimtwifi? Anything newer than 14.1 (7.1.2)?
17.1 is available for klimtdcm at :
Download and Install Lineage OS 17.1 for Galaxy Tab S 8.4 (Android 10 Q)
Now you can install Lineage OS 17.1 on Galaxy Tab S 8.4 which is stable enough to use as a daily driver. Finally, Android 10 Q is official

Also....what is the model number of the klimtdm?

Port new lineage os to mako(LG Nexus 4)

Hi. I want to try to build lineage os 17/18 for my old phone. I have env and I already build package for other phone. For Nexus 4 there and only some old lineage os 15 builds. How to prepare lineage os 18 based on lineage os 15? Is it possible or maybe it needs to be done from scratch. Is there any instruction how to do this?
Porting a ROM means there's a similar device with a working LineageOS on it. Which means it's already built, and only small modifications to make it stable for you.
Porting doesn't work the way you described. You can't build Android 12 on top of Android 8, every new major Android update, Google releases a new source code.
Then, manufacturers/developers modify it to their sweets. What you want to do is to build LineageOS 18/17 for an unsupported device. There's a lot of guides online about it. The context matters.
Can you share some links about building lineage os for unsupported devices? Will it help somehow when there are some old versions builds?

Samsung Galaxy S7 (herolte) - how to downgrade from lineagos 18.1 to /e os?

Hi folks,
I have a Symsung Galaxy S7 (herolte) and have built lineageos 18.1 for it and installed it via twrp.
This works fine so far.
But now I just want to try /e os because I saw that the herolte is officially supported. That means that they have a stable build based on Nougat.
According to https://doc.e.foundation/devices/herolte/install it can cause problems to downgrade from higher versions of lineageos to this build.
How can I avoid these problems?
Thanks in advance

Build LineageOS from source for Samsung SM-A500FU ?

Hi,
I'm a seasoned Linux user, but I'm relatively new to the world of free operating systems on smartphones. A couple weeks ago I bought an old Samsung Galaxy A5 (SM-A500FU) just for fiddling with LineageOS.
I spent about a week experimenting a lot and taking notes about ADB, Heimdall, TWRP, flashing ZIP files, etc. I found out that unfortunately LineageOS isn't officially supported for this phone. On the other hand, I managed to install a custom (unsupported) version of LineageOS on this phone:
lineage-16_a5_releases/README.md at master ยท DeadSquirrel01/lineage-16_a5_releases
lineageos 16 releases for Galaxy A5 SM-A500FU. Contribute to DeadSquirrel01/lineage-16_a5_releases development by creating an account on GitHub.
github.com
So much for a successful first experience.
Here's a very general question. Since there is no official LineageOS ROM available for my phone (as far as I understand the platform is a5lte), can I build a recent version of LineageOS from source for my specific device? Is this a more or less trivial task (like building LineageOS from source for an officially supported device) or will I have to jump through a series of burning loops?
Cheers from Austria,
Niki
