[Q] Replacing build.prop?

hi!
in order to test something, i need to replace the build.prop in root/system with a modified one. but trying to delete this file with astro manager displays an error message, and just copying the modified build.prop over the old one doesn't work too (nothing happens).
so my question is: how do you replace such a file?
thanks in advance for your help

are you serious!?!?!?
If the build.prop is located on the Android folder IT HAS TO BE A SYSTEM FILE !!!
if you mod the system files you could break android or the system just won't let you do it, you will need R and W privileges to do that.
edit the system files from your PC or just boot up in to windows mobile.
use some common scene next time.
hope it helps!

Do you use a cyanogen build?

yes and there is already a cyanogen rom posted with the proper build.prop fixed, so you won't have to edit anything, just search for it.

mmmh actually cyanogen made things easy to replace a system file, just copy your file into sdcard/android/root/system and reboot.

thanks for your help / posts. but unfortunately they're not helpful.
yes, i am serious! and yes, of course it's a system file. i know as well that modification might brick android.
there are reasons for modifying this file. some people seem to be able to, e.g. for chaning screen point density or modify the data passthrough.
so, please tell me, how can i edit/modify a system file from pc or windows mobile when its within the data.img-file?
thanks for any tips / hints on this.

use root explorer

Thank you VERY much for your help - I finally got it to work by listening your instructions. It is simply different if you have HD2 and plus CM mod. That figures why it was going back all the time to 180 instead of changing it - because it runs from sd card and that's where it needs to be replaced as well ...

system notifications

I see my system notifications are stored in /system/media/notifications but even with root Im not able to drop a new file withing this directory. I would like to do this because Handcent doesnt give me the option to select a different directory.
Any suggestions on either dropping a new sound file in the /system/media dir or using a custom sound file for Handcent?
Thanks

You should be able to put something in /sdcard/media/notifications

You have to mount system with root explorer, ADB, etc. It's read only by default.

I've tried a root file manager without success. Is it possible to change the directory permissions using ADB?

If you use root explorer, there is a little button in the upper right that toggles read write permissions.

Sweet
For the next person, I can confirm this does work, you just need to make sure the permissions are correctly set on each file and the phone (or SMS) app needs to be restarted to take effect.
Thanks everyone.
P.S. I hope you guys get a commission!

How do I edit my egl.cfg file?

Ok so Ive searched around to try and find a solution to my battery issues and it seems that if I edit my egl.cfg file to take out the android line it may get some better life so I wanted to try it.
Well I figured you couldn't change a system file while it was in use, but I cant seem to find anything that say how to change it. Everything I see says just go in there and modify it. Well again the OS will not allow that. I change it and it doesn't save, it just goes right back to having the android in it. Like I said I figured you couldn't do this, but then again I cant find proper instructions on how to actually do it.

Use root explorer and mount system as r/w. Then edit the file.

Accidently uninstalled stock messaging - impossible to get system/app to r/w?

Is there no way to get system/app to r/w? Been trying every app and terminal command to let me remount so I can reinstall my backup of the messaging apk and it just doesn't work.

I use Root Explorer and have had no problem using"Mount R/W" in system/app.

Hopefully, this is the right one.

Bleh. Copied to system/app, still get application not installed. Reboot with it in there and it doesn't show up either. At a loss here.

Any chance you can toss me the matching .odex file to that apk?

Here you go. You'll need to rename the file to delete the .zip extension.

Yep, they're set correctly

Now it's giving me the option to update or new install this system app. Problem is I don't see an already installed version obviously.

try downloading a custom rom for your cellphone, just for extracting the messaging app

have you tried to use adb to install it?

[Request] Verizon Visual Voicemail APK

Is there anyone out there who is still running the stock version of lg g2 24A that could pull the VerizonVVM.apk from system? I have my phone on cloudyG3 and I really don't want to have to restore all the way back to stock just for this one apk. it seems like a waste of time and internet. I just was wondering if there was anyone kind enough to take the time to do this for a fellow user.

Here you go sir...

Thanks man, now I don't want to sound dumb but when I put it in /system/app and changed the permissions to rw-r--r-- and rebooted nothing happened. Is there a specific way about installing this

You have yo install it using a PC , copy the .apk file and plug your phone using USB (as media sync) and paste the apk file right inside the download folder.
Next , unplug your phone , go to play store and install "astro file manager" then browse through the download folder inside your phone , and simply install the app.
I hope I helped
