Mount /system RO/RW [ROOT]

★★★★★ After rooting my Samsung Galaxy S3 i9300, I found out that a "root file manager" was required to access the system files where bloatware apps reside. So I downloaded ES File manager, but my ROM would not allow root access. Dumped that and downloaded Root File Manager. ROM allowed root access, but this version NO LONGER INCLUDES the ability to mount this files as -RW. I could not move any files or rename them. Finally, after spending far too much exasperating time on Android forums where no one mentions the above, I found out that my Root File Manager did not have the Mount /RO /RW feature in the Root File Manager used in 2011 on the forums. There are LOTS of posting about how files cannot be managed even after the ROM permission are granted. It seems not too many people realise that this mounting process is essential since the default is read only. A kind soul on one of the forums posted about this essential app which is needed to work with the files. I downloaded it and finally, finally, finally, after hours and hours of time spent trying to get this to work, I managed to get the youtube.apk renamed and the modified youtube.apk (listen with closed screen) installed!!!

★★★★★ Works on android Nougat!! Don't know why people keep rating this 1*. This app saved me! Thanks a lot

★★★★★ HTC Disfunction Just a note..that it didn't work for rooted VM HTC Desire 626s. It's an HTC thing. We can achieve root but can't edit the system files or debloat the HTC junk out! Thanks for the tip about editing in ADB!

★★★★★ worked like a charm! been having issues enabling root access in es file explorer and this little app fixed it! THANK YOU VERY MUCH!

★★☆☆☆ doesn't work on Nexus 5X @ Android 7.1 doesn't work on Nexus 5X @ Android 7.1, just says it's not compatible, however I have root

★★☆☆☆ Does not work on Sony Xperia Z1C on 5.1.1 rooted Android

★★☆☆☆ Not works for some Android devices The app is need a fix for some Android devices, please fix it, it says the system folder is changed access for system folder but the system folder access didn't changed, still same, can't do something in the system folder, please fix it. I hope you to fix it

★★☆☆☆ Doesn't work on ZTE ZMAX I'm rooted and on BrokenOS, but NOTHING can change /system on this phone. This app got my hopes up, but the toast message should reflect whether or not the app WORKED, not just say "/system is now R/W" regardless of the outcome. I'm not mad about it not working, but a false positive like that is pretty weak.
