I have a rooted Galaxy S5 SM-G900V, lineage_klte, ARMv7 Processor rev 1 (v71), Kernel: 3.4.113-lineageos #1 SMP, Oreo 8.1 that a friend asked me to modify.
I need to modify the platform.xml file to allow the system to write data to the external sd card. I need the ability to modify this file. The current permissions are: rw-r--r-- 1 root root, however I am unable to save any modifications.
I am unable to modify the file permissions and would like to know how to do so. Note, I am looking how to change the file permissions and not how to or what syntax to use in the xml file, or if it will allow me to have the system recognize the external sd card for saving data. I am perplexed on why I am unable to modify this file.

So, how do I change the file attributes for platform.xml allowing it to be modified? I thought that there was a hidden immutable attribute on the file but there is not(at least that I can determine).
Related question, is there any other website to post this question? Any help is most appreciated.
