/system is read only - Galaxy Note 4 Q&A, Help & Troubleshooting

Hi!
It's about an N910C, 5.1.1 Stock with ROOT.
I'd like to edit platform.xml to enable camera sound [on|off] option but I realized my /system is read only.
I already tried the remount option in console and also in ES File Manager but nothing works.
Does anyone have another idea?

[Q] How to replace files in filesystem

Hello,
i need some help.. the gps in my phone takes alot time to lock(?)...
someone created a gps.conf to replace the original file in system folder.. however i cannot replace the file neither edit it (i have root and tried it with ES Explorer)..
am i doing anything wrong? and how can i access the filesystem by usb? i tried booting the phone with power+vol up/down.. but there (pink screen) no drive was mounted..
thanks and sorry for possible english errors!
if you are using ES File Explorer, you need enable 'root' option and 'mount / /system as read/write' option to replace the gps.conf file
I have same problem.
I had rooted and flashed CW to get 2.2.1 -> Official 2.3 -> ICS
But on step 2. what needs to root and CW to get ICS it is impossible to get the system rooted and flashed again.
When going with + - on boot to magenta screen, Windows (Or Linux) does not recognize any drives to be mounted. Were there a external MicroSD card in slot or not.
I have now rooted device two different way and both say that device is rooted. Even the phone itself says that it is rooted. But no sudo is working so I can not even enable SE Manager root functions or to re-mount any partition as read-write mode because applications does not have root rights.

when i am in the pink screen and connect the usb shouldn't i see the 3 drives (fs, internal sd, sd)?
No, only image folder.

How to Edit build.prop file in Nexus 4

Hi ,
i like to install My galaxy app in my Mako running on lollipop - unable to edit build.prop tried multiple tools.
Can some one help me to edit the file .
Thanks in advance
You need root, and a root file manager like root explorer from play store. Mount the /system partition as r/w, open the file, make changes, and then save and set the partition back to r/o.

Can't mount /System as R/W

Hi,
I recently rooted and installed Cyanogenmod 13 on my S5 however I've been having issues with the battery. I lose around 20% on idle in an hour. Under clocked my CPU to about min 900 and max 1000MHz and its gotten better, however, still got battery and a little bit of over hearing issues. (gets a little warm on idle which shouldn't at all)
I'd heard its the NFC that's causing these issues so wanted to delete that but I'm unable to mount the system as read and write and I've tried with many programs and the terminal.
Any suggestions? Thanks

I have previously set root access for both apps and ADB. However, still cant mount the system as rw.
What are you trying to set it R/W with?
Just use ES File Explorer, enable Root access in the tools left side menu, and edit whichever system file you want

I tried ADB, root explorer, Solid Explorer, Mount /System RO/RW, etc ... and even as you mentioned ES file explorer, however so far none has worked :/
With ES file explorer when I try to mount as RW, it fails to do so for only two folders in the device. both /system and /firmware-modem which I find odd and yes I have enabled root and granted permission.
Any other suggestions? Thanks
System is already RW with ES File Explorer if you have granted Root permissions to it
What are you trying to do?

So basically I'm trying to delete system/app/NfcNci folder. I have attached a photo on how my es file explorer looks for mounting rw and ro. I can mount anything to rw except for the 2 that are ro and remain ro even after setting them to be rw. I have granted root through superSU and the developer options
Thanks
I wonder if it's because you've flashed SuperSU, when CM13 doesn't need it, maybe it's conflicting with the developer options root toggle
When I flashed CM13, I didn't flash SuperSU, I just went straight to developer options, and enabled root for all apps
What happens if you just go ahead and try to delete that file/folder with ES File Explorer (After enabling root in ES left side panel) ?

Yea unfortunately I didn't know cm13 had such option only after flashing with SuperSU
When I do so it just say the file is read only and doesn't delete.
I'm updating cm13 atm. If that doesn't get me anywhere I might full unroot through SuperSU then root with cm13.

I'd just wipe SYSTEM & CACHES from TWRP - flash the latest version of CM13, root from Dev options, and see how you get on there
By doing that, you don't touch your data, installed apps, or anything else, they are on separate partitions - so they'll still be there when you boot back up
So I couldn't just delete caches and system. Because after doing so and flashing CM13 it wouldn't boot up and I tried multiple versions so I ended up wiping everything except for SD data and then installed the latest version. Then rooted through CM13 itself and then was able to give system RW permissions. So all is good now including the battery life. Thank you for your help Detection
Good stuff

Do you think this will work with my hard bricked phone?
so if our system is still ro, all we have to do is mount rw every time? I was hoping that we would only need to mount it like one time, because im basically doing the same thing I was doing before.

test this. you might need to rename the zip file to bootanimtion.zip.

Hello sir,
My phone is running B25. Will this cause issues? Do I need to downgrade?

I use ES File Explorer. Open the app, wait for su to grant it access, then change the system to RW. I've noticed that the phone will freeze if I tried to switch to RW before the File Explorer was granted su access.

I noticed that too. I also tried to see if root explorer would mount rw after I used es to mount rw, and it turns out that u still have to mount system separately in both file managers. Bummer because I was looking for a way to always have my system mounted as rw between both file managers.

I'm guessing once a custom rom is available, the whole system RW situation will be situated. Is there an advantage of root explorer over es explorer?

I personally use root explor to chmod files, I dont think es can do it, however es has its own perks as well, so I just keep both just in case

Lol, actually you can put init.d scripts in /sbin/.magisk/img/.core/service.d/ and they will do it on boot.
Try my attachment.
