[ROM][10.0][OneUI-2.5][UNOFFICIAL][EOL]LineageOS-17.1 for samsung M51 - Final

[myghi63]

well, thanks for all the support LahKeda! your work is amazing

if i flash this rom then back to stock, dual apps feature will not work?

I will test it right now, then I'll flash the newest lineage rom to see if the recording problem is fixed or not. I hope i'm wrong about the dual apps feature. (Spoiler that everyone knows: I was wrong.)

I restored my system and tried dual messenger with telegram. It works! I was wrong!

Proximity is partially broken. the screen doesn't turn back on until the call ends.
Adaptive brightness is working, but it takes a few seconds until it detects the light changes.
for the screen recorder, did this problem appear in the latest build or all the builds?
For network doesn't reach LTE make sure that in network settings that the preferred network type is LTE

So I installed the latest build to confirm and yes, it seems like all your builds are lagging while recording the screen, no matter what screen recorder I use. All the major animations seems to be lagging so much, and if you go to the developer options -> show taps, EVERYTHING lags, like 20fps.
My workaround for this: I'm now using KISS launcher, which is very light on GPU resources, and I disabled all the animations (I do this on basically all my devices), so the recordings are now acceptable.
Thank you a lot for fixing offline charging and gapps!
On my device (M515FXXU1BTK4) the speaker sound is a little bit louder now, not too much improvement but thanks again!
I also found a Dolby Atmos that works for this rom, on a telegram group for A10 devices. I coudn't find who actually created this (no one on this group knows), and I don't know how to create a thread about that, so i'm attaching the .zip here. Please make a thread about that!

Thank you very much for testing the ROM. I'll try to figure out why the ROM is lagging while recording it.
I'll put dolby atoms in one of the reserved comments.
If you tried other mods that work without problems then please, post it here!

If my Galaxy m51 using 730 chipset (Not 730G). Can i flash your rom.?

There are verients with different chipset?
How do i check my?

 

[kry52]

Unfortunately, the combo of Magisk and Gapps brings a reboot in 1 minute after OS login. I flashed the stock ROM via Odin and the current build after it and it didn't solve the problem either(

I'm not sure. But using 730G chipset is the most popular version of the m51. Only certain regions (like me, in VN) use the 730 chip version.

yes, you can. I'm using one with 730 chipset + 6GB ram + 128GB ROM, from brazil, model: M515FXXU1BTK4 (ZTO)

Install AIDA64 and see "Processor".

Please try installing it and then go to wipe -> format data, and then reboot.
Also, the "Magisk Hide" feature is incompatible with LineageOS, so if you're using it, the random reboot will probably be fixed if you disable that feature.

 

[myghi63]

Does it increase m51 performance?
Does it improve gaming...

It does improve the performance A LOT on my samsung m51. Everything feels way snappier than the stock rom and gaming performance is great too!

I guess Nepal's variant also use 730

Of course, I format data every time I flash the rom supporting encryption. It is mandatory for any phone. Thank you for your advice about Magisk Hide, I'll definitely try it today, however, SafetyNet won't be passed without this option activated...

If you find a way do make safetynet work without MagiskHide (since it does not work with lineage) or a way to make MagiskHide work properly, please tell us. I did never bother of that problem since I don't use gapps and DRM-based stuff, but I guess that a lot of people who use it will like.

I found a way to turn SELinux from "permissive" to "enforcing". It did not required any code modification, just configuration. I also noticed that the lowest frequency of both CPU and GPU was not the lowest that the chipset supports, which can decrease battery life without improving performance at all.
The way I found to fix these problems was using an open-source tool called "hKtweaks": https://github.com/corsicanu/hKtweaks/releases/
It does need root access (I'm using magisk for that). Open app -> Miscellaneous -> SELinux State -> Enforcing -> Apply on startup. The kernel already supports, it's just not enabled by default.
To save power without affecting performance, go to CPU -> Minimal CPU frequency -> 300MHz (both big and little cpu). Do the same on GPU at 180MHz (at least on snapdragon 730, probably will be the same on 730G).
I also set the CPU governator to "conservative", which can affect a little bit of performance in some scenarios, but also helps to save power.

I can set SELinux to enforcing, but I left it permissive until we fix all selinux denials.

Is it play certified and safety net passed?

First of all, thank you @LahKeda for your efforts! Really appreciate this positive shift in M51 development. I'm looking forward to buying you a cup of coffee as soon as I get my salary later this month.

Secondly, how can the average user contribute to debugging? I'm about to make the jump from stock, though I hope VoLTE, in-call-Bluetooth and SELinux will soon be working as intended. What kind of information might be valuable to you (logs, ...)?

Lastly, how's everyone's performance and battery life compared to stock? Has it been comparable or even better?
