Proprietary Lib Cleaner (PLC)
Linux shell script that allows you to silence certain lines from chatty proprietary binaries/libs which makes logcat actually readable, instead of it getting spammed by binaries such as mpdecision or thermal-engine.
Made with intention to be easily extensible for end-user. (would love to see a big database of hexxable strings)
Why I have created it.
I have made this shell script because I have experimented earlier with replacing hex strings in proprietary files, which worked out very well. I have had a lot of hassle trying to make the hex string replace work. But I found this great tool called Swiss File Knife that allows you to make hex replacements by just entering the string. Because of this it was very easy to create a template system so that users can easily add more entries to the database, rather then needing to adjust code of script every time.
![]()
The template system works like this:
Every binary/library is placed in the corresponding directory but in a virtual replication, in these files are the lines that need to be hexxed out of the binaries are present. nothing less nothing more.
![]()
![]()
Example 1:
~/ProprietaryLibCleaner/dbs/system/bin contains mpdecision which is a regular text file with the following strings inside it:
Example2:
~/ProprietaryLibCleaner/dbs/system/lib/hw contains sensors.msm8960.so which is also a regular text file since its a patch, it only has a simple reference inside (but a very annoying one)
These 2 examples are listed in the shell script, when more is added it is automatically appended in the 'database'
![]()
![]()
Last but not least is the patching process which is done on a 'fail-safe' method, it first checks whether its actually applicable before making any changes, if not it will skip it, so it won't make your files unusable

Instructions for normal usage:
1. Download latest release
2. Unpack somewhere on PC
3. Run script with ./PLC
4. Install ADB + ADB USB Driver if not installed
5. Install Swiss File Knife on Phone if not installed
6. View targets & patches
7. Set target and patch
8. Profit
