Bricked Note5. In TWRP Recovery 3.0. Need to delete folder in /system/app. Error:1

[SOLVED] - Apparently, I lost the ability to *read* also. When I went into TWRP, I must have clicked the "keep the system read-only" button. That would prevent me from deleting files/folders. I hereby select one card from the Smacktard pile.


Evening all,

Sprint Note 5, Rooted.

Tried to manually make an application a "System App". This is what happens when you give a monkey the *tools* but not the *brains*:confused:. I'm plenty technical, but I've not done this before.

I installed an app, then went into the data\apps directory and copied the entire application's folder into \system\app.
When I rebooted, the phone gets stuck on the Sprint LTE screen.
When I boot into TWRP, and into Advanced / File Manager, then go into the offending directory, I get the following:

File Operation Complete
Failed
rm -rf "/system/app/com.incorporateapps.fakegps.fre-1" processes ended with ERROR: 1

I get similar messages when I chmod, delete, move, or rename.

Any assistance you could provide would be MUCH appreciated. I'm bricked and cannot work until I get my phone back.

Thanks!
Pete
