Cannot edit build.prop on rooted developer preview 4 - Google Pixel XL Questions & Answers

I just flashed developer preview 4 and rooted but I cannot get the build.prop edited. I've tried multiple apps but always says error saving. Had anyone gotten the build.prop edited?

I have successfully edited the build prop by using root explorer. Make sure you are rooted and allow super su to use root explorer.
You will will need to hold down on build.prop to highlight it, then go to menu and select, open in text editor.

I am rooted and I did give permission to root explorer. I am able to mount the other files and folders as read write but it will not let me Mount the system as read write. I've tried multiple apps it all says error saving.

I've tried multiple. Its not the file explorer. I've tried re flashing the factory image but still will not let me edit any system folders or files. I think that maybe it is systemless root. Not sure how I got systemless root or if it is possible to get regular root. Is there a setting is Supersu?

You may have a SUPER.img - i just learned about this myself - its a combined image containing /system - /vendor & /Product - it looks like it is similar to Systemless root or system as root... idk they are weird but i do think its possible to modify build.rpop, but it may require a PC.... Im looking for a way to edit build.prop myself and learning all this now.

[Q] Cant edit or delete instal-recover.sh

I am trying to use clock work mod to instal custom rom.... I am running the latest ics release rooted and unlock...
you need to download root explorer
then go to "/etc"
then click "Mount R/W" on the top of the screen,
and then delete install-recovery.sh
What is the question?
If you ARE rooted you need to install a file manager (Ex. Root Explorer), set R/W and either delete or Rename the file. Suggest you simply rename by adding a .bak to the end of it.
Once this is complete flash the recovery image through fastboot.
BTW .. you could have posted this in the Clockwork thread and the instructions I gave above are already there.
Edit: LOL ... I must type too slow. In 7 minutes you got three identical answers.

Make sure you mount the system as r/w.

Cannot edit build.prop P7 (B126)

So my problem is that I can't edit build.prop. Already mounted r/w and I have tried root explorer and different build.prop editors but changes do not save.

Yep it's rooted. Do you mean that try to edit with adb?
There is something wrong with root. Most of the apps works fine with root permissions (titanium, set cpu) but some apps says that they cant get root permissions even if super su says root permissions granted. At the moment root is from twrp but I have also tried rooting with root genius with same results.

[Q] Unable to edit build.prop

So I have successfully rooted my wife's TMobile D851, which was verified using joeyk root checker app from the playstore, but I am unable to edit the build.prop so I can hide the nav bar and install lmt launcher for pie control. Am I missing something? I have no issue with my Nexus 5 or any other phone I've tinkered with and I am drawing a blank on what the issue is.
I'm hoping it's something super obvious that I missed and I'll feel stupid after I'm told what I am doing wrong.

I had thought about that so before I made this post I did a adb pull /system/build.prop and edited it with notepad++, as you suggested, but then I am unable to actually push it back. Can I just put it into a folder on my phone and then use some root file browser like ES or whatever and set permissions that way?

Your description of the permissions is a little weird but I think I can figure it out. I imagine it's the same permissions the current build.prop has? My wife has now taken her phone and gone to bed so I will have to try this tomorrow. Thank you very much for your assistance!

How do I set /system as Rw?

I keep trying to edit build.prop on my 5x as I've done on previous devices in the past. Going through file explorers setting it to Rw doesn't actually change it. Does anyone know how to actually set it as rw so it can be modified? I'm trying to add eis, if anyone else has tried.
Thanks!

are you sure you are properly rooted? what method did you use?
do other root apps work as intended, which file explorers are you talking about, are you on stock?
just asking, since there are root procedures around through which you funnily enough end up with a r/o rooted device. also the more relevant information you give, the easier it is to help.

I followed a guide in November, don't remember which. All done through adb. All root apps work fine, xposed, titanium Backup, etc. I've tried stock, es file explorer and FX file explorer. Also for giggles I tried Rom Toolbox Pro. Also, in twrp it does say I'm not encrypted.
When trying to edit the file, it only gives me a cannot modify file error.

Did you mount system rw before trying to edit the file?
In ES it's under Tools > turn root explorer on, then tap it and mount rw
Same for me...

Using ES worked perfectly. No other actually worked. Many thanks!

Question LOCKSCREEN OGG FILE LOCATION

Hello I have been trying to look for the lockscreen.ogg file location. It has seemed to changed in Android 12 if I'm not mistaken. It was located in System/Media/UI but it seems that is no longer even there with Android 12. Does anyone have any idea where this is? Thank you!
Try system/product/media

That is exactly the spot I was looking for. For some reason I cant get root explorer to mount R/W to overwrite the old file. Root Explorer does have SU access as well. Any ideas?

There are one or more Magisk Modules that will make it appear for all intents and purposes that you've overwritten or changed a file. It will do what you need. Because root is systemless, you can't (and shouldn't want to) actually change or delete any system files for real. I don't know the name(s) of the Magisk Modules that will do that, as I haven't had a need, but many users in this section have suggested others use such modules to do something similar to what you want to do.
running "settings list global" on adb shell gave me this location "lock_sound=/product/media/audio/ui/Lock.ogg" I was gonna check on root explorer but forgot im not rooted right now but hopefully that is it.
I just am trying to change the sound when locking the phone.

Can you rename the stock file to lock.oggbak and then paste the new sound in obviously with the name lock.ogg?

You can not because root explorer is not able to switch to r/w. But I tried anyways and failed

you have to create a magisk module yourself and replace the file, with the one you want.
google around for a template of a simple magisk module, recreate the directory inside the magisk module where the file you want to replace sits on the phone (system/product/media/audio/ui), drop the new sound file there, zip the magisk module template and flash via magisk manager and do a reboot.
dynamic partitions donĀ“t allow for r/w mounting. replacing the file systemlessly via magisk during bootup is the only way.
