I have a problem with making a /system folder into read/write permission. I made root (TWRP 3.2.3, SuperSU-v2.82 - in TWRP is unchecked read-only) and the problem is tablet freezes EVERY time a make change from RO to RW.
I used Root explorer, ES file explorer, Root file manager, Super manager... Every time when I change it and press "ok" tablet freezes. Also I try via terminal "mount -o rw,remount /system", nothing, a download apk "Mount system RO RW ROOT" and apk said it did it, by when I check in file explorer it is still read only. (also I try via fastboot and comannds pull and push and it said that file is read only)
I really need to make changes in /system/build.prop and I'm out of options...
Anyone?

Hey have you found a fix for this???
I have the same problem.
device x00id os 7.1.1 (downgrade from aosp 9.0 > 8.1 > 7.1.1 because everytime i upgrade i had battery issue)
twrp 3.1.1.0.zip
supersu 2.79.zip (i've tried to use magisk.zip before)
1. flash twrp
2. flash su.zip
3. reboot system
4. open root explorer
5. copy folder /su to sdcard or internal storage. (my device doesnt freeze when copy file from root to sdcard, but my screen freeze when try to switch 'ro' to 'rw')
6. reboot to twrp again
7. mount system
8. advance > file manager
9. copy all item in /sdcard/su to /system/xbin and /system/bin (i only copy file su to /system/bin)
10. tap every files that you copy and click 'chmod 755'
11. reboot system
now you can try to switch your 'ro' / 'rw' button in your root explorer. i think screen freeze while access root happens because root method (twrp and magisk) doesnt instal root as system ('respecting encryption' or whatever)
but i hate to see my device forced to keep updating apps like fb, messenger, ig that i dont use it. a lot bloatware that forced to instal in customer device that drain battery.
i hope this help you or whoever that has same problems. good luck.

Hi,
I tried changing file permission on one of the folders where I saved my photos to read-only using "Root Browser Lite".
The following error message came up: "Changing permission was not successful. Please note that some file systems do not allow permission changes".
I tried using ES file explorer but it also failed.
Could someone please tell me how I could change the file or folder permission. I wanted to prevent the photos from being accidentally deleted by my children when I let them browse their photos..
My phone I9300 was rooted using CF Auto Root.
Thanks
Get root explorer, it's much better.
Simply long press on a folder and the permissions option is there.

Don't forget to set to rw at the top of root explorer before attempting to change permissions
If you're talking about the internal memory, you can do chattr +i /data/media/[name of folder] to set the immutable bit. EDIT: You need BusyBox installed for the chattr command
This works because /storage/sdcard0 (JB's usual mountpoint for the internal eMMC) is a fake FAT32 file system Google created for compatibility; the internal eMMC can really be found at /data/media, which is of the ext4 filesystem.
For the external memory, you can try SGS3 Easy UMS and set the read only property on the folder using your computer. (I can't find mattrib for Android.) There is no guarantee that Android/Linux programs will obey the RO attribute, however.
The reason why Root Browser Lite & ES File Explorer didn't work is because they work on UNIX file permissions, while a file system formatted using FAT obviously doesn't understand them - it would expect DOS/FAT attributes. That said, though, have you already backed up the data you consider to be important?

=============
Thank you all for your advice. The file system explanation betw FAT and ext4 fs makes sense. I have BusyBox installed.
Via Terminal Emulator, when I did "chattr -i /data/media/DCIM/Camera", I got a "permission denied".
Is there something that prevented me from this?
I'm running ICS.
Thanks
Did you type su before the command..
Just asking..

Thanks Zoot1.
I did that.
Image Gallary is still showing /mnt/sdcard/DCIM/Camera as "writeable".
What is the difference between two folders /data/media/DCIM/Camera and /mnt/sdcard/DCIM/Camera?
Thanks,
Note that I used +i in my example invocation of chattr. - removes the attribute; + sets it, which is what you want

Thanks qwerty12, after 'chattr +i folder name' , I return to root browser lite to change permission on mnt/sdcard/DCIM/Camera, I still get permission denied. What did I do wrong?

Mount System RW
The problem is that your system is currently in RO (Read-Only) mode.
Even if you are root, can't mess with system files if the setup is like that.
ES File Explorer works because it has an option (that DOES work) to mount the system in RW (Read-write) mode.
On my ES File Explorer Version 3.0.0 it goes like this:
Android menú button--->Tools---->Root Explorer--->Mount R/W.
Set: /system (or all of the options) to: RW----->OK.
Now, explore your files using the ES File Explorer interface on your phone and you should be able to erase every file and apk you want even if they are system files.

How can Install the Camera apk on the rooted stock with writable kernel DNA? I replaced this apk with the original stock camera apk, changed the permissions to rw--r--r--. Then, rebooted. But, I don't get the new camera options.
thanks.
Did you mount the /system partition as read/write? This is in addition to the writable kernel, and must be done each time you want to change /system while booted. Most root capable file explorers (i.e. ES explorer) have an option to do this, or you could use this adb command
Code:
adb remount

I have a problem getting full write access to my system folder, and all other folders / files which are in same path where system folder is.
I have just rights in SdCard Folder..
THis is the path where i dont have any permission to change something: is this normal?
If yes, so how can i push an apk to system folder then, if i need a new keyboard for instance...?!

Are you using adb or some Android based file manager to copy the file?
If it is adb = use adb remount, this normally solves the problem. If you are using some file manager - make sure system is mounted in RW mode..

i guess you want to acces those folders with a file explorer? afaik it is normal that you don't have acces to other folders than sdcard, you have to use a file explorer with root capability to acces/write the other folders.
I'd recommend you to use ES File Explorer, very good app for me.
To grant root acces for it:
open the app -> press menu -> Tools -> Root Explorer (now the app should ask for root acces) -> Mount R/W -> set the paths where you want write acces to RW
now you should be able to write to the other folders.
If you want to use adb push (USB Debugging mus be enabled):
- copy the desire file or apk to your adb/fastboot folder
- connect your phone to your computer, open command line, navigate to adb/fastboot folder on your pc if necessary
- type "adb devices" (to see if your phone is recognized)
- type "adb push <name_of_your_file.file_extension> /path_of_your_destination_folder/<name_of_your_file.file_extension>"
Example: adb push example.apk /folder1/folder2/example.apk
I installed [ROM] [4.4.2] CyanogenMod 11.0 from here
everything runs fine,but i cant write files to the internal storage.
For instance if i start the gallery app it tells me "No internal storage available",another app tells me it "cant write to the cache folder" because the sd is full,mounted,or write locked.Root explorer sees all the files but cant delete,move or copy/paste anything.
Apps that save/download files like podkicker or reddit act normal when trying to save the file but after the download starts the notification disapears and the file is simply not downloaded.Apps that stream content work fine,like youtube,or the stream feature of podkicker.
I have over 2gb free space so its not that,and if i plug into my pc i can move and delete files no problem.I like the rom and like i said everything else seems to work fine.
Thanks in advanced for any help.

run cmd and get adb going
type
adb shell
stop
rm -r data/*
mkdir data/local
mkdir data/media
exit
then push the rom file with [adb path]/adb push [rom path] /mnt/storage
when the push finished type adb reboot hold the volume down button and press enter
once rebooted into sde go to dev menu remove android kernel if necessary then choose flash kernel and initramfs
copy the files over

Its weird because i can write to the root directory but not any folders in it.Root explorer and es file manager say that its read only but neither will let me switch to read/write.
I made a logcat from boot[at least i think i made it rite,never had to do one before]
But i cant post the link because i dont have 10 posts just add this rpqjxGhG to pastebin
This all also happens with external sdcards as well it turns out,i just tried to make a new file with the built in file manager on the external sd and it said it requires elevated permissions,
root explorer just says file creation failed.
I also get constant "unfortunately,Trebuchet has stopped" messages when doing any thing.
I have also tried terminal emulator for kicks.
I gave it su then tried
# mount -o rw,remount -t yaffs2 /dev/block/mtdblock0 /system]
didnt change a thing
then i tried
adb remount
this said error: device not found
Im pretty sure its not my tablet as i can can go back to stock/stock root and write files perfectly fine,ive also re-downloaded the rom twice just to make sure it wasnt bad,and ive probably flashed it around 20 time by now all with the same result.
I hope someone can figure something out.

When installing the CM11 firmware, did your format/reset your "android+storage" in "format device" recovery menu?
Storage files should be /mnt/sdcard/ (internal storage) and /mnt/media_rw/sdcard1/ (extern sdcard).
I'm able to create files in both directories as well on the file explorer.
If you want to "unlock" the root ( / ) partition you have to use this one inside the shell:
Code:
mount -o remount,rw /
but this don't have some effects to the mounted storage files.

I was updating by putting the firmware file on the the device then rebooting and flashing the zimage and initramfs,
The reason being if i reset the "android+storage" dosnt that mean the firmware is deleted?
adb dose not see the tablet when its in recovery,it does see it when its on[am i doing something wrong there?],so i cant push the files,and if i export the data partition in windows a pop up and says it needs to be formatted before it can be used.so how am suppose to get the file to the device if i format everything?

Hi,
I tried to rename root's .ogg files on my Samsung Note 9(Oreo) and unable to do it. I found limited information here. I can rename the .ogg files in the older Android though.. What I have tried so far from these app and failed;
1. ES explorer
2. root explorer
3. mixplorer
4. total commander
Permission for "RW" only can set on "mixploer", and "root explorer" but after tried to copy over the root folder, it prompted failed to copy. Although I can set ES exploere to "RW" mode but it fools you to believe it has rename the file but in reality it was unable to, what a screw up.. Anyone has successfully rename files in root folders?
I did not try this in "safe mode" though..
If you had Magisk rooted phone, try ExSDcardEnable module. Or can you move file to internal storage for rename?

I was tried to rename the files at internal storage but not able to. I can copied files out to ext memory card or pen drive. After that I was not able to move back to override the current file/files.
Magisk is installed but can't find "ExSDcardEnable module".. Is it in the Magisk manager?
This file ".ogg" is at "system\media\audio\xxxx.ogg" and unable to edit. Looks like the ownership of Oreo harder to make change now..

Well, at least you have remount /systen as read/write with "mount -o rw,remount /system" or in TotalCommander is easier.
Yes, it is downloadable module in Magisk Man. Latest is ExSDCard Write Access Enabler v3.5 (Sorry for bad name). The new access path for our externals SDCards: /mnt/media_rw/SDCARDNUMBER/

By running from Magisk Manager -> Plugins -> sign "+" -> choose *.zip plugin, after automatic install, reboot phone.
Or MM -> Downloads -> search for ExSDcard -> Click on ExSDcard write access enabler -> Install then reboot.
@Hi adeii,
I installed the "ExSDCard Write Access Enabler" by download through the Mgisk manager's download and wonder if correct. I attached a screenshot here.
I tried to use the total commander to rename the ".ogg" files but failed after I have re-mount the R/W. I wonder if I did correctly by adding the folder as shown in the screenshot.
Did anyone successfully overwrite the files in Oreo? I run out of lucks... Not much information about this issues also.. From Jelly Bean to Marshmallow I have no problem to overwrite files(I did not try on Nougat). But Oreo, until now I still have no way to overwrite a simple file like .ogg.. :crying:
