I accidentally deleted the system app
com.samsung.android.MtpApplication from my rooted phone running Lollipop 5.1.1 using Titanium Backup. I had a backup but when I tried to restore it, it failed with an "App not installed" message.
I also added the app to
system/app through ES File Explorer but it probably needs to be added to the phone's apps DB (considering it didn't show up as a system, nor a user app even after rebooting) and I'm not aware of how to do that.
Now, I'm stuck with a rooted phone that cannot connect to Windows through the MTP Application, but have a backup of said app. How can I install it manually
