Hello again
Thnx for answer..
İ think the problem is file system.. As you know gm5 plus using Squashfs file system. because of that we cant changce r/w permission for this file system. Only option is using custom rom.

Please Wait. Our Team is bringing CyanogenMod 13.0 for your device please wait.
We are at the end of success.
Give a chance like.
Take full system backup
Then copy system backup to your PC
Rename system.squashfs.win to system.ext4.win
As well as if system.squashfs.win* exists rename as same.
Format your system partition as ext4 using twrp.
Copy the system.ext4.win to your mobile and restore the backup.
Try this method.

You cant r/w system because GM 5 Plus uses squashfs file system. Squashfs cant r/w it can only ro. You can flash systemless root and xposed.

Hey there,
AirAudio has been kicked by Google because they didn't like a link to a rooting-website inside the description anymore, written 7 years ago.
Its successor is called AirMusic and allows to stream some apps (eg. YouTube, YT Music, Deezer, PodcastAddict , radio.de, Plex and more, you have to try it out) without root on Android 10+.
On rooted devices, all audio can be transmitted.

AdAway on stock nougat- copying of host file failed

hello im getting the following message everytime i try and download the lists "copying of host file failed! please read help for more information"
ive just updated to the android 7.0 through the developer program, twrp custom recovery installed with root access build number NRD90M
just wondering what could be causing this and if i can do anything to try and fix it thanks

Is your /system set to read only, or read/write? If read only, adaway will not be able to update /system/etc/hosts

i have it set to read write im gonna try to flash the systemless hosts right now ill update how it goes

flashing the AdAway_systemless_hosts_v2.zip in the recovery, then unistalling and reinstalling the app seems to have worked

you can also use Magisk now to enable complete systemless root and then the hosts file /system/etc will be forwarded to the systemless version

I didn't even install Adaway, I just downloaded a host file and replaced it in /etc/
Works good enough for me and one less app running...

In the exact same boat. Frustrating. Tried Adfree, to no avail. Adaway, to no avail. Tried the adaway bind zip file, making hosts writable, and even System to writable. Nothing.

i have fixed this by converting adaway from user apps to system apps using Link2SD, reboot and adaway working properly again

Very old thread, but I've had exactly the same problem installing AdAway on the last 3 or 4 phones -- all but one running Nougat 7.0, the other on Oreo 8.1. This was when trying to install AdAway versions 3.1 and 3.3.something.
I finally got it to write hosts file updates using one of the following, not sure which was the key:
-- Installed version 3.2 which had been running problem-free on an old phone for years. The biggest difference is this older phone is running Resurrection Remix 5.8.3 (Nougat 7.1.2).
-- Before trying to update the hosts file on this fresh install, I went straight to AdAway preferences and set "Check for updates daily", "Enable webserver", and "Start webserver on boot". After making those settings I tapped Download Files and Apply Ad Blocking, and it successfully wrote to the hosts file.
Again I don't know which was the fix. It seems weird that version 3.2 would work when a version just before and after it didn't work for me. But of course it is possible that the version is the difference. It seems even more weird that those 3 little preference settings make any difference at all . . . unless it's just the act of writing changes to the AdAway app itself.
Before installing 3.2, using Root Explorer I checked permissions on the working phone and one non-working phone, for the systems and etc folders, and for the hosts file itself. (In all cases AdAway is/was set to use /systems/etc/hosts.) I also checked Android permissions in the Apps list. All permissions were exactly the same on both phones: 0755 for system, 0755 for etc, and 0644 for hosts. No permissions assigned via Android.
Hoping this bump will also get fresh attention from somebody who might know the details of a real answer.

@Moondroid
Why the hell you trying to make some really old ass version of it work instead of installing the newest version? Lol
I've been using 4.2.7 and though its kind of weird on a fresh install I need to update and apply the hosts twice before searching for newer hosts comes back its up to date. But at least it works.

[SOLVED] Unable to read/write internal storage

My OnePlus 5 is unable to read or write the internal storage. I don't see any file in Gallery or any other app that lists media files. File explorer shows how much space is used up but it says my storage is empty. Can't download files, can't create folders or files. Sometimes it fixes itself and I could access all my files. Or sometimes rebooting the phone fixes it. I tried some command lines in adb trying to fix permissions, but got no luck out of it. Somebody, please help!
P.S.: My phone is rooted with SuperSU, runs on the latest OOS build, has Xposed installed and I haven't tried switching roms.
Update: Uninstalling Xposed solved it.

Did you install Xposed? If yes, it gives this problem for which I had to uninstall Xposed.

Even I faced this issue in my unrooted device

I had this issue on the first boot after rooting using Magisk, a simple reboot fixed it. So maybe try rooting using Magisk? I know it's not a complete solution but just throwing a thought out there.

If it's fixing permissions via terminal then sorry, that didn't work. As I said, xposed was the problem. Uninstalling it fixes the problem.

Happend to me 2 times... a simple reboot solved it.

Glad it worked for you. Sadly for me, fixing permissions or contexts didn't help. Anyways, I said it earlier, uninstalling Xposed fixed it.
@SynisterWolf please close this thread. The issue is fixed.

Yea I didn't have xposed installed you see, plus mine reoccurred. Was only trying to help.

Unable to modify /system folder

I've looked all over and I'm unable to find a solution or even what's stopping me from modifying the /system folder in the root directory. I can remove files from that folder and all of it's subfolders but I'm unable to add any files into that directory. I am rooted on the T-mobile OnePlus 6t that has been converted to the international ROM. I know my root works cause I can perform other root functions. I also cannot modify the /system folder from TWRP either which is really strange to me. Also, when TWRP prompts me to install the app, it just reboots recovery since it's trying to install it as a system app which I can't do for this odd reason I have yet to find out. This issue all of a sudden showed up after an OTA update and re-rooting after. I have tried reinstalling TWRP, Magisk and Oxygen OS itself but the issue persists. I have also tried running "reboot disemmcwp" as root in a terminal window AND using adb but I guess that command no longer works. Any suggestions welcome as this is the last place I can find an answer to this issue.
Edit: found out I'm unable to uninstall system apps for some reason. So the issue isn't space related.

Known issue that in the Newer OxygenOS versions there is no free space in /system. I'd download Solid Explorer and check the Free Space in the Root Directory.

I've thought about that before. I use root explorer and can see there's more space than needed for the files I want to insert. Is there some buffer space needed in there and how much?

I was actually able to find the issue. Space was the issue. I guess there's a space buffer needed from what a file explorer says is left and what's actually left. I uninstalled a couple system apps I disable anyway and was able to insert files/apps into system again.

I made space easy I have the new OnePlus camera apk 125mb the old one is 67mb

Error 'system' not in /proc/mounts when trying to make cerberus as system app

Hi, a few days ago I manually updated my OP6T to the latest version manually (I can't do it normally because I'm rooted and the system shows me an error)
I use the Cerbeus anti-theft application, I like to turn it into a system application to have full control of my phone in cases of emergency (theft, for example).
The point is that I can install magisk 20v and root perfectly, but when I try to make cerberus or any application as a system application, it shows me the error 'system' not in / proc / mounts, I use link2sd, titanium back up, root explorer all the options does not work, i cant mount rewrite to erase system apps but i can't make normal apps to system app, I tried to update the ROM stock directly from the official website, but at the end, always shows me that error, can anyone help me with this problem?
Thank you! if you need more information tell me
I'm so sorry if my English is not too good, I'm still learning

I've used it for a few apps that need system level access and it's worked great

Yes woked perfectly thank you very much
EDIT:
I tried a few days ago, All converted applications were removed with factory reset are they not supposed to be already in the system partition?

AFAIK Systemize Is the easiest and recommend way. About the things being removed after factory reset, that's normal as Systemize is System-Less. All changes it makes will be reverted after a Factory Reset.

Magisk modules don't touch physically system partition. It's the only way to keep security verifications green. Magisk modules are in data partition and are 'mounted' is system ram disk

Hi again guys, now im trying again to make Cerberus as system app I was able to solve the problem about mounting system, through ADB I placed the APK manually in the system / priv-app folder, I gave it permissions with CHMOD 644 i restarted and effectively became system application Up to this point everything was in order, until I did a factory reset, I got stuck in the boot animation, To solve it I had to boot TWRP and manually remove the apk from the priv-app folder, with this the system boot normally (curious because the root permission was there Despite having restarted the System)
Someone have any ideas to solve it? I don't care about magisk and if the safety net are in red
Thanks!

Help guys, any ideas ?
