Couldn't uninstall preinstalled apps though I have root because of RW permissions

[Foryl3k]

Good morning from Spain.
After rooting SM-J530F (Samsung Galaxy J5 2017), with This Tutorial https://forum.xda-developers.com/ga...nt/guide-root-twrp-recovery-sm-j530f-t3685871 ) and flashing TWRP, I cannot uninstall preinstalled apps like Facebook because Root Uninstaller PRO says: couldn't apply RW permission on /system folder. Any Ideas?

Thank you.

I would strongly advise against uninstalling any system apps. This will not save you any space on your device. Instead go through your app manager and clear data, uninstall any updates, and disable the app. If disabling is not an option, then freeze it with Titanium Backup.
Also, I would make sure you have the proper firmware file at the ready, in case you bork it.

Please get you root checked, if yes there's no problem just use the superuser to uninstall system apps..

Yes, I used Root Checker and it says Root is correctly installed.

By the way, my binary is SuperSU.

If it's correctly rooted you can uninstall.

A LOT of Nougat OS's (even Customs) are actually RO, leaving system mods to require TWRP use to accomplish the feats
