I guess somehow I fixed it. First I set the governor to performance from adb shell like this:
Code:
$ su
# echo "performance" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
And checked the governor with CPU-Z app. Then I restarted the phone and the governor got reset to interactive. But checking cpu-z again and BOOOM all 8 cores are working.
This fixes the problem at least for a few hours. The next morning they weren't working again but going through the procedure solved it this time either.
Proof: PUBG mobile ran waaay smoother after all 8 cores went online.

edit2: If the screen turns off after enabling the cores they go offline. Any devs here who can tell why?
edit3: found a dev who has fixed this bug here. sadly the link doesn't work.

Well guys, I just found out that the issue with cpu frequencies is just a problem with displaying the frequencies in apps like cpu-z and the cores themselves are working fine.
You can find the post that the maintainer of this rom explains this problem in old posts of this forum.

All cores work fine in the first few minuts but then go offline until the next reboot
As for the post above mine please post a link to the forum you talked about

Hey, I found a bug that other older ROMs don't have. The bug doesn't allow certain apps to use their Android/data/ folders. For example, Vanced can't read its folder (I can't download anything, it gives me an error), Fasthub can't download anything either, Dashchan can't access its folder as well.
I've tested it with ViperOS and RR from this forum and they worked fine, but these are very old ROMs and they've got other bugs I doubt anyone could fix at this point.

    LineageOS is a free, community built, aftermarket firmware distribution of Android 7.1 (Nougat), which is designed to increase performance and reliability over stock Android for your device.
    It is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. You will need to provide your own Google Applications package (gapps). LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.​

    Whats up guys! Some of you may already know me, or may have heard of me, from my work in ha3g (Galaxy Note 3 exynos)... Today I come here to bring you my latest work, a fully stable and functional LineageOS ROM for the Samsung Galaxy S5 exynos variant...
    It took a lot of time and effort to bring this up to this point, when I started with this project like 10 days ago I found a device that was really broken (random reboots, bugs all over the place, missing features, terrible battery life and performance...) I entirely redid the kernel from scratch, and redid 90% of the device and vendor trees to get the result we see here today... The device works like a charm, battery life is great, it is complete feature wise, and nothing is broken (except for the two minor bugs listed in the OP bug section...)
    As I always do, i will give you THE reminder...
    *You NEED to flash this clean (wipe system, data, cache and dalvik-cache before flashing)
    *Don't use xposed/magisk/mods... these kind of mods will certainly interfere with the well functioning of the system...
    If you didn't follow these procedure, and encounter a bug, please don't report it... start over the proper way and try to reproduce the bug again before giving any report...
    Also, i do not take into consideration the reported bugs I can not reproduce in my own device... the device I hold in my hand is the same you have in yours, if it works for me, it works for you...
    This ROM is labeled as STABLE... what does this mean? It is suitable to be used as Daily Driver and has no major issues...
    What's next now? Bring up the selinux policy, get cves for the kernel, and go Official...

    Guess I don't have anything more to add for the moment... I hope you enjoy my work!
    Happy flashing!

    EDIT: Added some screenshots! Sorry for the crappy battery screenshot... I dont have a proper one... but you can tell by the screenshot that the stand-by times are great!

    Want Root access??
    Just flash with TWRP the LineageOS SU Addon zip file found on the download section... Flash it after you have flashed Google Apps!!!
    Then enable the developer options menu with this guide:
    To enable Developer Options, open the Settings screen, scroll down to the bottom, and tap About phone or About tablet.
    Scroll down to the bottom of the About screen and find the Build number.
    Tap the Build number field seven times to enable Developer Options. Tap a few times and you’ll see a toast notification with a countdown that reads “You are now X steps way from being a developer.”
    When you’re done, you’ll see the message “You are now a developer!”. Congratulations. Don’t let this newfound power go to your head.
    Tap the Back button and you’ll see the Developer options menu just above the “About Phone” section in Settings. This menu is now enabled on your device—you won’t have to repeat this process again unless you perform a factory reset.
    Now go into the developers options menu and find the option to enable root access!!

    Flashed the SU Addon and now you want to remove it from your phone??
    Just download the LineageOS SU Addon remover and flash it with TWRP...

    OMS SUPPORT HAS BEEN DROPPED FROM THE ROM SINCE 20170902!!

    Hi, thank you for this amazing Rom, battery life is fantastic. Only problem is an annoying echo in telephone or whats app calls, not in my side, but for those I am talking with. Can I do something to solve this problem or does anyone else have this echo?
