Hey so recently I played around with my twrp on my Samsung Galaxy Note 4 and I accidentally clicked fix contexts and when I rebooted my phone I found that I could not download media, take pictures, screenshot, videos and unable to access files in video/photo editors and I typed in the code
ls -alR > /beforeperms.txt
Only to find that it says
File system read only
I used termux for it.

So I went across a thread on another forum thst fixed my problem and I used Android terminal emulator to type in he codes.

this has been in zero-reply long enough, plus i've seen an identical post on another forum...
this is not the right forum, you really need to look at
