How to remount system using SuperSU

- I already rooted my device using supersu but my device won't boot because I changed some files in system framework.
- Have access in adb and there's a su binary
- I tried to copy files to /system/app but it requires permission.

some stock recovery have mount /system

unfortunately I can't boot to recovery..
I tried to adb reboot recovery but it won't go to the recovery ui

You via ADB can run any command as superuser:
Code:
adb devices
adb shell "$(which 'su') -c '<YOUR_SHELL_COMMAND_HERE>'"

Hi, thanks for the reply!
I already tried in shell, su -c 'mount -o remount,rw /system' but still it didn't change into rw

you are rooted?
this is kinda sound stupid but it might work download "fx file explorer" from playstore then give it root permission then access this directory from fx file explorer "System (Root) > System" then while on that folder access upper right options then change to rw

just be careful with fx file explorer... one wrong move and you might accidentally delete whole partition lmao

Yes, I used SuperSU to root my device.
My device hanging in the bootloop so running an app is not possible.

Maybe SELinux is enforced, also maybe AVB 1.0 and/or AVB 2.0 is enabled ( AKA bootloader is locked ): both deny to operate on /system partition

Unable to write to system folder while rooted.

Hi everyone,
Are there any custom ROMs that will allow me to write to the system folder? More specifically, I have a few files that need to go into /system/bin/ for a tasker task.
I have tried while rooted the classic way with the Stock rom, but every time I reboot, the files get erased after I place them.
I have tried it on LineageOS as well, and get the same result.
I have an Android Device, GPD XD+, with CleanROM installed, and I am able to write files to the /system/bin/ folder for my Tasker task with no issue. I just want to be able to replicate that on my Pixel 4A.
The furthest I have gotten on my own is to try to disable verity, but that doesn’t work on any of the ROMS.
Without trying to install every ROM and testing, is there a ROM out there that will allow me to write to /system/bin/ without it erasing it on the reboot?
Thank you all!

try
Code:
adb shell
mount --remount / -w
this should allow you to write to the system partition. copy the files you need onto any folder on your phone first and then move them to their destination.

I left something out of my post, whoops. In the process of trying to reflash the stock image after LineageOS, I accidentally made it so my phone does not boot after the fast boot screen. I can fix it when I have some more spare time this weekend, but for the time being my phone isn’t useable without more flashing. I was thinking I could post here and have a brainstorming session before I dive back in (since I spent half of Saturday trying to get it to work).
I will try that command first thing though once I get my phone up and running again. If it was that simple, I’ll be kicking myself for sure. Thanks for replying so quick!

oh no! well, best of luck then. crossing my fingers for you!

Recovery Disappears

I bought a phone (ZTE 2050) that has next to nothing as far as development goes. I have tried to install TWRP recovery but it had never actually worked. I have tried using various tools that port recovery to MTK devices. None of them have worked. I have been able to achieve root through Magisk. However, when I do, I no longer have the stock recovery either. There are several other problems that happen as well, but nothing I cannot work around. What could I be doing that is causing me to lose recovery? The chipset is MTK6771 and it is an ARM-V8 64 bit and it is running Android 9. Literally the only things I'm able to find online regarding this phone is the sites that I believe only copy and paste from other phones whether the root method actually works out not. Almost everything tells me to use MTK Tool but that definitely doesn't work. I have issues with Smart Phone Flash Tool working as well despite all drivers being installed correctly. The only way I have been able to achieve root is through unlocking the Bootloader and flashing. And even though I follow the instructions on commands, I still lose the stock recovery. Any help would be greatly appreciated.

I have flashed the stock system at least 50 times by now. I have tried flashing everything in different orders as well. When I have root, it always removes the recovery. When I open my file manager, I use Solid Explorer, it tells me there is no root file system. I have tried other root file managers as well. They all tell me the same thing.

Android is rooted if su cmdlet is present in Android's filesystem

I've got a $100 Chinese MTK phone and the one redeeming feature is that once the bootloader is unlocked, you can fastboot over USB (bootstrap).
I used SP flash tool to backup the ROM and WwR_MTK to extract the partitions allowing me to make my own custom recovery to boot with fastboot. Briefly, I found a twrp recovery online for another MTK phone and just played around with zImage & initrd.
Shell commands, dmesg, cat /proc/partitions & blkid on the phone come in handy to track down in partition layout. No need to flash anything so don't get issues with /system/bin/install-recovery.sh

I got it to hang on to the stock recovery. However, the bootloader remains unlocked. If I lock it again in fastboot, it will not allow me to boot the phone. When I try to flash vbmeta, it tells me there is no such file on the system.

I'll give that a shot. I just tried to open my root file system and it told me that BusyBox isn't installed. I thought I had read that BusyBox wasn't necessary with Magisk. Last time I tried to install a BusyBox, it screwed the whole system up. Is there one you would suggest? I've seriously messed with this phone 1000x's now and it's made me giggle shy to do anything to it at the moment.

Some devices have 'toolbox' or 'toybox' as a limited replacement for busybox (ls -al /bin/ls should reveal what binary the sym link points to).
I've used the ru.meefik.busybox app from the play store.

"cmdlet" not found. Yet Magisk is installed and I am able to access root.

If you can successfully apply su ( read: Switch User cmdlet ) then it got installed by whatever method.

Busybox is just a tool / binary executable command to replace missing
linux commands. You don't need it installed on the phone, just access to the binary to run commands in the shell (copy it from /data/app/....) - its statically linked so should run without issue in the shell.

Ok, I understand that. What I don't understand is why I am now being told that vbmeta cannot be found and installed and my bootloader must remain unlocked. Or why I cannot install recovery without losing recovery.

Question How to pull Build.Prop...

Here's where I'm at. I've got the system to give me the Mount /System option in recovery, now i just need assistance getting the build.prop pulled to my PC. What's the procedure for pulling the build.prop from the Android to PC via ADB while the system is mounted in recovery? Why am I getting one of these two ADB errors?
Error 1: Connect failed: closed.
error 2: Failed to get feature set: no devices or emulators
OR, am I approaching it wrong?
Thanks in advance,
K0mraid3

you dont need to be in recovery to do it via adb....
adb pull /system/build.prop
that will pull it to where evr you run the adb command
which would be
C;\adb more than likely
or you can choose a destination with
adb pull /system/build.prop c:\buildprop
if you create a folder called "buildprop" in the root directory of c:\
at least thats how i remember doing it many years ago, ive been away for a while at her majesties pleasure, so i cant try it currently as im not rooted

Thanks, so far, its still for some reason denying me permission when OS is booted. So i just cant quite figure out where im supposed to execute these commands, is my issue. I can boot directly to BL from recovery menu, but i can also mount system. i think maybe i need sto send command for r/w.. will try that now.

Another question, when i mount /system in recovery, does that carry over on boot?

no you can re mount system via adb though
Code:
$ adb shell
$ su
# mount -o rw,remount /system

1.Needs root for this command. If he have rooted device then why so much trouble needed. Simply use root explorer to copy
2.Since long Samsung have removed system from proc/mounts still magisk system_root can be used
3.Even with system in mounts you can't do system rw on S22 because of Samsung have implemented extra layer of protection. Even not with magisk system_root too
Indeed as of now there is no method available to make stock system/vendor/product/odm rw on S22 even with root access.
4.To copy file from system rw mount not needed, ro is fine

So my device is strange. It doesn't have root, but it indeed shows options in recovery to apply updates from ADB, SD Card aswell as boot directly to BL and to Mount /System, but when I'm booted, the OS is denying me permission to "Su" . I have verified that USB debugging is activated. So I'm trying to see if there's a way to pull the build.prop from Recovery since the Mount /System option is available, but my computer refuses to recognize the device in while in recovery, but easily finds it in Download, BL mode. No FRP lock. No accounts on device. But also no option to unlock bootloader. This device in particular is/was a development sample so I have no clue what the current state of the bootloader etc is in terms of being unlocked prior to me working on it.

It'd also worth noting that this device was loaded with Android 11 when I received it. I'm not kidding. So idk what's going on with this FrankenGalaxy

These options are normal in stock recovery and can be used only for flashing official zip (OTA), To have root access on your recovery, you needs custom one (TWRP) which is in development stage on S22
Without twrp, You needs to root device (must have oem unlock option in development option) to access system files while you are booted to android.
Android 11 on S22? Can you show me screenshot of settings - about phone - software info?

Thanks for the clear answer, that's kind of what I'm working on is trying to gain root access, but like you said, I need oem unlocking, which isn't on this device. So I'm trying to find a backdoor/vulnerability that will take me even one step closer to atleast finding a way to set ro.secure. prop. Something VERY interesting I did find, is that if you put the device to Debug medium or high via device keystring activity, and play with the key combos, you can get booted into a mode called RDX, if you plug it into your dev system with the right drivers, it's treats the phone as if it were a Disk and shows a bunch of VZW upgrade software ment for PCs. I've installed it but haven't got it working quite yett.

No idea what you have shown in screenshot, I'd asked something else.

[GUIDE]How to install Bromite SystemWebView without Magisk (Android 12+ included)

This has not been tested on any other version other than Android 12.1. If you have issues please report them here or open an issue on GitHub.
I just upgraded to LineageOS 19 from 18.1 and as usual I want to apply my own modifications on top of it but the NanoDroid script that I previously used doesn't seem to work on 19. I couldn't find an answer neither on r/LineageOS, r/fossdroid or even XDA so I wrote a way to install Bromite SystemWebView in a way that's a lot more elegant and doesn't need Magisk or root.
Method 1 (preferred):
Download the flashable package and install it in recovery mode either by placing it on the SD card or by sideloading, then reboot:
Bash:
adb sideload BromiteSystemWebViewOverlay.zip
Download the latest Bromite SystemWebView release and install it as you would a regular app.
Navigate to Settings > Developer options > WebView implementation and select Bromite SystemWebView.
Method 2 (legacy):
Enable Rooted debugging by navigating to Settings > Developer options > Rooted debugging.
Connect your phone to your PC and type
Bash:
adb root
Mount the vendor folder:
Bash:
adb shell mount -o rw,remount /vendor
Copy the package downloaded from here to the overlay directory:
Bash:
adb push treble-overlay-bromite-webview.apk /vendor/overlay
Mount the system as read-write:
Bash:
adb shell mount -o rw,remount /
Copy the OTA survival script to the appropriate location:
Bash:
adb push 99-bromite-webview.sh /system/addon.d
Make the script executable:
Bash:
adb shell chmod 755 /system/addon.d/99-bromite-webview.sh
Reboot the device:
Bash:
adb reboot
Download the latest Bromite SystemWebView release and install it as you would a regular app.
Navigate to Settings > Developer options > WebView implementation and select Bromite SystemWebView.
For a more in-depth explanation check the GitHub repository.

It is worth mentioning that after installing Bromite SystemWebView, developers will not provide any support when their banking applications are not functioning properly. Proven in practice.

I never encountered a mobile banking app that uses WebView (at least for the main functionality), but your mention is most welcome.

I've been debloating and degoogling and old HTC 10 running android 8. I've been wanting to get bromite installed because chrome is installed as the webview. I'm rooted, but unfortunately the webview manager magisk module fails to install.
I just found this thread and would love to give this approach a try.
I have the /system/addon.d directory. I have /vendor but not /vendor/overlay. I have /mnt but not /mnt/system. The scripts I have in /system/addon.d (fdroid and minmicrog) only reference the system app and priv-app directories so no help there, unless those locations are fallback options. Can your instructions be adjusted for android 8?
I also have a rooted microg LOS 19 moto g7 that's served as a reference with my debloating/degoogling effort. I looked at the contents of /vendor/overlay there and found that all but one of the apk's in there had "vendor" in the name, so I searched recursively from / on my HTC and didn't find any apk's with "vendor" in the name. Do you have any other ideas on how I might identify the equivalent directory on my HTC?

Yeah I've seen that. It's a bit complicated, which is why I was hoping to either do it via the magisk manager module or via these steps. Ultimately if all else fails, I may give that a try. Hoping @arovlad will have the magic touch here, but I totally understand if there's no desire to invest time figuring out how to do this on an old device and android version.

I am all for supporting old hardware. The thing is I actually thought every device running Project Treble (TL;DR Android 8 and above) use overlays of some kind.
I have the following ideas:
Do steps 1-3 as explained above and then make a folder called overlay inside the vendor partition:
Bash:
adb shell mkdir -m 755 /vendor/overlay
Do step 4 and then run the following command:
Bash:
adb shell cmd overlay enable com.arovlad.bromite.webview.overlay
TheShanMan said:
The output from that command is nothing.

Does it output nothing or does it output cmd: Can't find service: overlay? If the service cannot be found then the device may not be Treble-enabled. Please check if it is.
If it is try running:
Bash:
adb shell cmd overlay dump
and paste the output here.

Thank you for your patience and investing time in this.
Edit: added link for Treble support

It outputted nothing, and the treble check app says it's not enabled. Does that mean I'm out of luck or is there anything else to try? Thanks!

You mean the first command, the second, or both? Please use quotes accordingly so I can know what you're referring to.

You may be. You mentioned earlier that the Magisk module fails to install and that may be because your ROM is not Treble-enabled.

Have you tried creating the overlay folder manually and then enabling it via ADB as I wrote above?

Sorry, when I said it outputted nothing, it was in response to your question about the command "adb shell cmd overlay list". I tried creating the overlay folder and enabling it. The enable command gave no output so I don't know if it worked or not. I tried rebooting and then checking the webview setting in dev options, but it's still not there.
I'm guessing you assumed I would also then do steps 6 and 7. Is that right? If so, I'll have to try creating a magisk module to put the script in that location and hope it runs. I can't touch the actual system partition because doing so causes VoLTE to stop working on my phone, so I'm doing all my debloating/degoogling through magisk modules. I don't mind giving this a try, but since my phone isn't treble enabled, I'd like to verify that you think I ought to before I spend the time creating a magisk module for it.
Appreciate the help!

Run the following command:
Bash:
adb shell dumpsys webviewupdate
and if it outputs org.bromite.webview is NOT installed then it works.

If your phone is old and doesn't receive official updates anymore, there's no need for addon.d, so no.
May I have the contents of the / (root) folder? Is there any partition called oem or odm? If so, what do they contain?

I'm a little confused by you saying it works if it says "NOT installed", but no, it doesn't say anything about bromite. Here's the output:
Current WebView Update Service state

Yeah, it's a little confusing, but if the overlay was successfully installed it should output NOT installed.

Then it doesn't work.
TheShanMan said:

Then try putting the overlay package inside, enable it (even if there is no output, just in case) and reboot the phone.
If it doesn't work, then you are out of luck as far as I know and your only option is to patch framework-res.apk manually.
Edit: clarification

Not only did that not work, but the /oem directory got wiped out after booting up. It must get populated by something during boot. Thank you very much for putting in this much effort to figure out how to make this work in my case. I wish I could've reported victory, but maybe I'll get it figured out via framework-res. I've tried one approach with that unsuccessfully so far (which hung during boot). I'll try more things and hopefully get it figured out! Best of luck with your project and thanks for offering it to people!

If you actually DO find a way, it would be awesome if you could report back. Maybe it will help others in the same situation. Good luck!

Hi. Thank you for that step by step process of installing Bromite Webview.
I am a little confused about the 'vendor' part. What does that mean and why is it there? And as a consequence of that, I do not understand steps 6 & 7 beyond adb 'push' or 'shell'.
Any help is massively appreciated!

This has not been tested on any other version other than Android 12.1. If you have issues please report them here or open an issue on GitHub.
I just upgraded to LineageOS 19 from 18.1 and as usual I want to apply my own modifications on top of it but the NanoDroid script that I previously used doesn't seem to work on 19. I couldn't find an answer neither on r/LineageOS, r/fossdroid or even XDA so I wrote a way to install Bromite SystemWebView in a way that's a lot more elegant and doesn't need Magisk or root.
Prerequisites:
adb
Rooted debugging or a custom recovery
Installation guide:
Enable Rooted debugging by navigating to Settings > Developer options > Rooted debugging.
Connect your phone to your PC and type
Bash:
adb root
Mount the vendor folder:
Bash:
adb shell mount -o rw,remount /vendor
Copy the package downloaded from here to the overlay directory:
Bash:
adb push treble-overlay-bromite-webview.apk /vendor/overlay
Mount the system as read-write:
Bash:
adb shell mount -o rw,remount /
Copy the OTA survival script to the appropriate location:
Bash:
adb push 99-bromite-webview.sh /system/addon.d
Make the script executable:
Bash:
adb shell chmod 755 /system/addon.d/99-bromite-webview.sh
Reboot the device:
Bash:
adb reboot
Download the latest Bromite SystemWebView release and install it as you would a regular app.
Navigate to Settings > Developer options > WebView implementation and select Bromite SystemWebView.
For custom recoveries: skip the first two steps, enable ADB from recovery mode and follow steps 3-10 replacing /vendor/overlay with /mnt/system/vendor/overlay and /system/addon.d with /system/system/addon.d.
For a more in-depth explanation check the GitHub repository.

Hi, @arovlad thanks for this workaround. I'm running the exactly same LOS version than you on a OP6. But at step 5 i'm getting the following error : /dev/root is read-only any idea what can i do ? Thx for your help !

Starting Android Oreo, the vendor partition is a separate partition containing proprietary manufacturer code not part of AOSP. This separation ensures that the Android system can be updated without recompiling the device-specific software. The vendor partition is typically overlayed over the system partition, making it easy to apply tweaks and modifications without actually touching the system. These modifications are typically named systemless.
Did you install Bromite WebView successfully?

Try the following command instead of step 5 and see if works for you:

adb remount
