What version of android are you using?

[PSXman_uk]

6.0.1

[2nHxWW6GkN1l916N3ayz8HQoi]

6.0.1

I was in a similar scenario before with an old phone with android 5. Nothing worked on 5, nor 6 so I had to upgrade to 7. Your device from what I can see, officially supports Android 7. Upgrade it via the official updates from settings. If it doesn't work, install a stock rom. The Python CDM dumping script doesn't work for versions lower than Android 7. And there is another dumping script that can work up to 13.
https://www.gsmarena.com/samsung_galaxy_s5_neo-6506.php

Android 5.1.1, up to 7.0
Versions: G903F (Europe); G903W (Canada)

[shellcmd]

first of all, since your device use so old Android version, you must ensure your phone has CDM, and security level should be L3, download drm info app from Google play or other place, check your phone's info.

[Attachment 77015 - Click to enlarge] Seems it is but i cant update the Andriod version

Maybe not L1 only perhaps

[shellcmd]

yes, it is L1 and you can use some scripts to force use L3. but you need update system now, if no official update, try some third-party rom, at least update to android 7 as @2nHxWW6GkN1l916N3ayz8HQoi said.

Seems it is but i cant update the Andriod version

I checked and there is no stock firmware for android 7. https://samfw.com/firmware/SM-G903F

So your best chance is a custom rom indeed (like lineage os, etc.). Research a lot in dedicated forums for android, such as:
https://xdaforums.com/f/samsung-galaxy-s5-neo-roms-kernels-recoveries.6574/

Look for your specific model. Since this is a custom ROM, I recommend just installing it to dump the CDM, and then reverting to a stock ROM, back to Android 6.0.1. Some custom ROMs have bugs (of different levels) if they aren't officially supported. Invest some time into research otherwise, you will brick your phone. Don't jump blindly into the first tutorial you find.

I have succeeded in dumping L3 CDMs from Samsung devices with Android 6.0.1 so it is possible.
Use an older frida version

[PSXman_uk]

Does the device need to be rooted or can i use another device non rooted

[Karoolus]

it needs to be rooted to be able to run the frida server

[PSXman_uk]

Which version did you use on Android 6 please i assume they need to match with the pc version im downgrading in pip

[PSXman_uk]

python.exe .\dump_keys.py

Loads the video but no output on dumpkeys window
