Nougat sytem patition read only - Help needed - LG G5 Questions & Answers

After the flash of V20a EUR-xx I would like to change my bootanimation and make some changes in my build.prop.
But it's not possible because the system partition is read only and it's not possible for me to change.
Root explorer did not work.
For this reason for example the use of faster GPS is not possible
Any help to make the system partition writable would be great.
Regards

Edit: Found solution by myself. Flashed no-verity-opt-encrypt-4.1.zip and now it works.

looking for help with that too. Nothing works: terminal on android; app mount system rw; adb shell; root explorers.

Same here ...
Tried TWRP 3.0.2.1 - Beta 1

SuperSU v2.78

Normal wipe, Format data, etc. etc. ....
Can´t get the system to R/W
FX File Explorer lets me turn system to R/W with root but nothing is permanent ( build.prop entries ) and deletes are overwritten and not permanent
SD maid wont let me delete bloat apps ....
Anyone an idea?

Hey guys. I know how to mount system as R/W (It's not forever but you can operate on system files).
App "Root Explorer" can mount system. Thanks to @marco_wack

[Q] Cannot mount system folders as r/w

Hi,
I'm rooted yet cannot mount system folders as r/w. I am definitely rooted (confirmed by using su command in terminal and the fact apps that require root are working) and noticed this issue when trying to install busybox pro.
It warned me that there was an existing busybox in /sbin and would remove it before trying to install in system/xbin but the installation failed.
I tried to remove busybox from /sbin but the folder would not mount as r/w in root explorer OR solid explorer.
I managed to remove the file in TWRP recovery though.
Weirdly, I've been using titanium backup to uninstall system apps without any issues.
How can I fix this? Repair permissions int wrp?
I presume you followed the same instructions as I. I am on the 621 and currently have the same issue (also rooted). But on my end it is actually worse. I cannot mount the system partition in TWRP either (I mean I can mount it but when I try to delete or move a file I get error messages), and something happened to my download manager (which basically means that for the time being I cannot download apps from Google Play or from the internet, etc). I have a good download manager apk, but when I try to install it it asks me if I want to update the existing app, and the operation fails - I have to try and find a 3rd party alternative for the time being). It is kind of a problem.
(to update, I have very limited r/w permissions in TWRP. If I get lucky I can make small changes.)

I don't think so. I tried this, and I eventually was able to view/attempt to edit file permissions inside of X-plore file explorer (don't know if it is a coincidence, but I first had that success opening X-plore in 'mount system r/w' mode after changing the i/o scheduler to cfq). Anyways, it consistently shows all 755/644 permissions, so the permissions are not being re-written upon boot from what I can gather. But if I try to edit permissions or copy files to System folders, I still got error messages to the effect of "you cannot do this,' even though it is a root file explorer and the system partition is purportedly mounted as r/w.
Try flashing this in recovery: SonyRICDefeat by dosomder.

Thank you for this. Has anyone ever tried this on the Z3TC? Mine is running smoothly enough such that I am reluctant to fix what isn't broken. It seems that early issues I had with freezes, TWRP, etc, probably had to do with my SD card and the Android media scanner.
I've tried it on the Z3TC SGP621. Thus the recommendation.

I have the exact issue in lollipop and I have tried flashing RICDefeat and I get errors.
Sorry for the Hijack :/
Use my RICDefeat from here and run it from terminal. Works only if you are rooted. Afterwards you should have r/w access.

Problem with root file system and with supersu binary update

Hello, im having a couple of problems regarding my filesystem as well as the app supersu and its binary file.
To start, i rooted with kingroot and switched to supersu using terminal emulator commands. There are still kingroot files in my xbin which i will attatch a picture showing the contents of my xbin folder in attatchments (i also have .tmpsu in xbin) please ask if you need more pictures or information of files located in my directories.
The problems i need help with is:
1. I cannot mount /system or any foler in that directory as r/w, i feel that there is a file located somewhere that is preventing me from mounting /system as r/w.
2. I cannot update the su binary, i have tried normal and twrp modes neither work. Ive also tried flashing the UPDATE-supersu-2.78.zip in twrp and that doesnt work either. It says that it installed but nothing changes once i boot back into system, i feel that me not being able to mount /system as r/w is preventing me from updating the su binary.
I need help on how to regain conrtol of my /system and how to update the su binary. Any help? Thank you

It says i have properly installed root access. Something fishy is going on with my root and my system.

I did try that too, it took around 15-20 minutes to uninstall then when i rebooted the app was gone but my device still had root. I did get it to uninstall root 1 time then i went and flashed the zip file and the same problem occured again. Maybe kingroot just f-ed up my device so root will never work properly again? Maybe a virus? Idk whats going on with it.

Your device does not have twrp/cwm port ?
It does, i have twrp(touch) 3.0 for blu vivo xl. Thats the only way i got my device unrooted one time. What i had to do i had to boot into recovery, mount /system, reboot into system then root explorer would allow me to mount /system as r/w but i believe theres a script or something somewhere that is locking the /system into read only mode cause after a short period of time (around 5 minutes or so) i can no longer modify or delete anything in that folder even though it still says its in r/w and if i close root explorer and reopen it it shows that its back in read only mode even though i didnt change it back to that.
Edit: if i mount /system in twrp and boot into system when i boot back into twrp system is not mounted anymore, idk if its supposed to do that or not.
These are the only possible solutions ive been able to find that do kinda make sense.
"It's because you need a boot.img with r.o secure=0 in the build prop" i went and looked and my file says r.o secure=1 that would explain why my system will not mount as r/w.
Another post i found said -
"I've found the source of the problem asking in the MIUI forums, the boot image will not accept a modified /system.
You have to use the adb interface: adb devices then adb disable-verity.
Disclaimer: I'm not responsible for any damage caused by these operations."
The second solution seems more reasonable and alot easier to do. My question now is: will one or both of these solutions possibly fix both my problems? And the second solution disabling verify should that be okay to do without messing up my device? I do have that recovery i could flash but dont wanna do anything that might make the phone not boot into recovery.

I just remembered something. I think i know what bugged it. I was trying to do an ota update for my device and it wouldnt let me. I found another app by chainfire called flashfire. I tried to flash the ota update and i had the option "inject supersu" enabled even though i already had supersu installed and everything else i needed for root. I guess doing that messed up all my su files ect.. But how do i fix it? I cant uninstall root cause my /system folder is locked into r/o. If i press full unroot in supersu it will remove the app (although it takes a while!) but all the files needed for root stay.
Guess there just no fixing this phone. Someone really hacked it good i guess, problem is still there and nothing can fix it...
Update - thread can be closed
Problem fixed, to fix the problems i was having i had to download the stock system files for my device and flash them, after that just installed the latest supersu 2.78 zip and remount problem is fixed.

system files not can edit

hi guys, i not can edit the system files
i try to edit(i'm using X-Plore and is with superuser + write mode) and not can edit, i got a error
i not use other explorer because i not find the root options on the aplication
Most likely your system isn't mounted r/w. Try and use root explorer, it has the option to quickly mount and unmount system.
hi, u can say how to do this? sorry for questions, i dont find the option to mount

Mount /system RW / RO Android 7.1.1 Lenovo Tab 4 10"

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.

[help] Redmi Note 9 pro [rooted] [magisk] file explorer

I run into following problem. I have successfully rooted my phone and installed magisk. Now what I try is to replace the bootanimation.zip...
But it fails at permissions. I granted superuser access via Magisk to the app (Es file explorer) and I also toggled the root option to in in this app. But whichever I try it fails neither can I delete or write to the system. I also tried different root explorers facing the same issue.
Those someone know how to solve this?
Thanks in advance
Graru1
Same issue here.
Sadly don't know an solution
Your /system partition where you want to replace the file is read only. Flash a custom rom or use this automatic script from this thread to rebuild your /system partition as read-write and you will be able to replace the files.
