[Q] Editing /system/etc/hosts file - restores itself after reboot

Hi
So I am looking at blocking a number of websites - no, I don't really want to do this through app's as a mere uninstall can undo the blocks.
I've rooted my phone, I've given +rw mount to /system/ and I'm able to etc hosts under /system/etc/hosts just fine.
However, as soon as I reboot, the system restores the hosts file to it's original state and all my edits to that file are undone.
Is there anything I can do about this? Please be a bit more specific than just "flash the kernel", thanks.

any time i edit anything in system folders i copy it to sdcard do my edits then copy it back and make sure the permissions are set correct i think it rw-r--r-- reboot and it should be good to go... for some reason i cant edit them in that folder but moving it to edit then move it back works for me maybe it will work for you too...

I can edit it no probs. I do my changes, test them out and they all work OK.
As soon as I reboot, everything becomes undone. AFAIK this might be some kernel protection.

The system partition is write-protected.

[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.

the build.prop is huge for the lg g3(to big for some apps) try copying it to your pc and editing it there with notepad++ end then placing it back and set permissions(important or you will brick)

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?

place it in /system then in es enable root explorer then click your newly added build.prop long click it then select properties then change permissions to
Code:
yes yes /
yes / /
yes / /

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!

[GUIDE] Increase Your Headphone Volume

If you are like me and like your music loud then you are also pretty disappointed with the low headphone volume of this model phone. V4A and Atmos improve things a little but even with them the volume is lower than most phones are factory stock. Alsa Mixer works to increase the gain from 12 to 15 (max) but only temporarily so I spent this morning finding a way to manually edit the mixer paths for a more permanent solution, which after searching all over had yet to find. Im no developer so it took me a while to find what I was looking for and was surprised to find out there's no less than 8 files that reference headphone L and R gain but I gave it a shot and now the volume is much better than it was.
I have attached a zip with the edited mixer_paths and mixer_volumes to save the time and trouble of going through all the files individually as I did. Just goto /product/etc/audio/hissc/ and copy/backup each of the following files to somewhere on your internal storage or SD card :
mixer_paths_BERLIN.xml
mixer_paths_hi6250.xml
mixer_volumes_BERLIN_ce.xml
mixer_volumes_BERLIN_cmcciot.xml
mixer_volumes_BERLIN_gcf.xml
mixer_volumes_BERLIN_normal.xml
mixer_volumes_BERLIN_unicomiot.xml
mixer_volumes_BERLIN_hi6250_normal.xml
Once you have made copies then move the files from the zip to this directory and change the permissions to rw-r-r with a file manager of your choice. Restart your phone and enjoy your music 20% louder all the time.
*This is only for headphone volume.
**I don't know if other builds are different but it works on B360

Nice, I'll test this as I'll have time! Sometimes i just think: "if only it was louder..." so i hope to gain some after this one

Bro all mesed up, snd me the original files pls

Please elaborate ,bro all messed up tells me nothing. What exactly is wrong? Are your permissions set correctly for the 8 files once you copied them to the correct location? If the instructions were followed it should work fine.
The only things that have been changed in all files are the values of HISSC_SMT_HSL_GAIN and HISSC_SMT_HSR_GAIN from 12 to 15, just like alsamixer does however this is permanent. In both of the mixer_paths files the strings are found only once, in the 6 mixer_volumes files I only changed the values under media-headphones and media-headset.

Nice, i will try
Can you explain me "and change the permissions to match those you just renamed, rw-r-r."
Thanks!

Always have a backup of original files before copying pasting anything. OP has shared the file though but it may not be the case all the time so always have a backup plan

You need to use a root explorer (like MiX, Total Commander, ecc.) to reach the folder listed in OP (/product/etc/audio...) and then modify the permissions of the new copied files to allow them to correctly works (long press on a file and then click on modify permissions -> flag the permissions as stated by OP, there will be dedicated boxes to click on)

Thanks for the explanation. Just a heads up to anyne using ES file manager the permissions are under properties when you long press on a file.

I followed instructions but after copy and pasting the files when i went to permissions it says they are already at rw-r-r Does that sound normal? I used Root Explorer Classic from JRummy Apps. I tried first with X-Plore but it gave me an error that I am not allowed to change the permissions or something like that. But regardless they all show it as rw-r-r before I did any modifications whatsoever
I rebooted but volume does not seem very much different. Its still not loud enough for me, when I get drunk I like to hear the music REALLY loud for head-banging

This really helped me out man, thanks!

How do I increase the volume of the main speakers?

Bootanimation - I changed the correct file, but it's still showing a different one

Latest April update and I have magisk 16.3 with 5.64 manager version. Everything works fine, but now i've hit a snag.
I wanted to change the boot animation, I changed the file /media/bootanimation.zip and set permissions 644 (rw-r-r) using 1)solid explorer 2)root explorer 3)adb shell (using mount-wo remount rootfs / to make the /media partition writable. multiple reboots of course. the files I set are "sticking" after reboot.
It's still showing stock animation.
I found an app that would change it though: https://play.google.com/store/apps/details?id=website.olivermillers.customboot2
I don't know what file it changed but it made a backup of my stock animation, and it was my stock animation (not the one that I had set for /media/bootanimation.zip). I tried to restore the stock animation manually, as described above, but now it just shows the boot animation set by that app, and I can't change it.
Questions:
1. What am I doing wrong and what did that app do correctly, that it was able to change the boot animation?
and/or
2. Is there a substratum module with a black pixel 2 animation? That's all I really want and I can change animations with magisk easily and reliably. Just can't find the one I need.

I did it using the root browser app and the bootanimation changed.. it's system/media I think

Like EnlXmA said, it goes on system/media. Using root explorer, I just place my new bootanimation.zip in that folder, add a .bat to my old animation, and just reboot. No need to change permissions at all. Here's a dark pixel bootanimation if you want/need it :good: https://drive.google.com/file/d/1zStFsJiqq5bLTp5krQnpwlztoJfK_B33/view?usp=drivesdk

Thanks so much guys. I feel so stupid. i've read your posts on this before, BAdger, even saw that same screenshot and download that same file from your drive. And yet I still thought it was /media, not /system/media. Thanks for the tip that I don't need to change permissions, too, I did not know that.
:good::good::good:
Would you mind posting a copy of the .bak file (the stock boot animation)? In my stupid attempts, I deleted mine.)

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 don´t allow for r/w mounting. replacing the file systemlessly via magisk during bootup is the only way.
