As said in the title, i wanted to try a netflix root bypass as i saw on a yt video so i added this lines to the file using a text editor and rebooted the android box. It's stuck on the boot splash screen. any way i can modify the file back to normal? it's rooted btw(the cause of the mess)
What's the device?
When you say that you "added this lines to the file using a text editor"
What did you do after that? Modify the system partition by replacing the build.prop file? Or some other partition?
If so, one cause might be that the device is now failing avb2 (android verified boot).
Even if the box is rooted, if avb2 is enabled, the system partition will still be checked by android verified boot, unless vbmeta is also disabled.
Some possible solutions are just to flash the original system partition back to the device, or if vbmeta is not disabled, to flash a patched version and try booting again.
