How to Change File Permissions without Root [via TWRP]

In this guide, we will show you the steps to change the permission of a file using TWRP, without the need for root. Recently, I wrote an article on how you can change the image of your device present in the About Phone section. To do so, we need to place the desired image file in the data directory using a root-supported file manager app and then change its permission to RWRR, again using the same file manager app.

The entire process was literally a breeze, however, the fact that you have to root your device was in itself a major factor that repelled the users from trying out this tweak. So I went on a thinking spree for a few minutes and realized that the entire task could easily be carried out even if the device isn’t rooted- you just need a working custom recovery. This is because the entire task was segregated into two steps- moving a file into a particular directory and then assigning it the permissions, both of which are supported by custom recovery as well.

Well, this is just one instance; there can be a plethora of other situations wherein you’ll have to change the permission of a file and doing so via root isn’t the most viable or feasible approach [due to the likes of Play Integrity fiasco, among others]. So in this guide, we will show you the detailed instructions to change the file permissions on your Android device without root using TWRP Recovery. Follow along.
