[11/8][MOD] build.prop edits

build.prop is a file in /system that sets certain parameters at boot. You can change or add to this file for varying results

Is anyone else dizzy after this?

Root Explorer is not saving your build.prop because your in R/O mode. when Root explorer tried to put you in R/W it uses the yaffs method, which will not work on a tab because of the file system method.
file manager hd works though

Thank you! I was wondering why R/W wasn't working oddly enough, I can overwrite the file by copy/pasting...

testing the scan interval change now. I remember back in the day being able to use build.prop to OC/UC a kernel on a device (still requires a kernel programmed to be OC/UC like pershoots) if you find it let me know.
ya, tested the wifi on the build.prop, no joy.

Update! Many more added, as well as better organization. Please help confirm what works and what doesn't.

i will give it try
thanks

can anyone tell me where i could change the layout for the keyboard?

[Q] Camera tweaks?

Lg Revolution Development Revival

Ok guys, im back.
I have a new project, I am going to jumpstart development for this phone.
So in post #1(this one) there is web links to development resources.
In post #2 there will be build.prop, sysctl.conf, init.d tweaks and other stuff of that sort.
In post #3 there will be links to ZIPS, with ROMs tweaks, and fixes.
dev resources:
http://www.lg.com/global/support/opensource/index
And maybe other stuff will be added later.

build.prop Tweaks For J7

build.prop Tweaks For J7​
The best build.prop tweak for J7 15
How to apply Tweaks :
1. Root your device and install Root Explorer (or any root file manager) then find build.prop located at root/system/build.prop
2. U can Use Root Explorer app or notepad++ to edit your build.prop
3. Open build.prop file with Text editor and Find last line of build.prop
2. Copy all of these lines just below the last line
3. Save the changes and set the permissions to rw-r-r (Remmeber to do that !)
4. Reboot and enjoy
Supreme Battery life (even more in idle)
- Better internet browsing & download speed (updated)
- Smoother experience
- Google DNS
- Better Microphone
- More Ram
- Better signal reception
- Wireless Tweaks
- Smoother video streaming and tweak media
- Faster Boot-Animation FPS (Just compare)
- Better call voice quality
- Game tweaks
- 3G Tweaks (NEW 2016)
- Indicator Hack(NEW 2016)
- Qualcomm Tweaks

You can also get a build prop editor from the play store. Some have these tweaks already built it and give you the option to backup your current build prop.
sent from this device using this app....

More than half of these settings are not even in the rom, are for motorola, htc or old versions of android. Please do some research before posting

Thank you for your continuous search advice from your butt .... Let the knowledge that most of the build tweek now use in the creation of Rohm and we are in 2017, such as dns ... This work is not for me ... and it is set for a workout just told me if I tried, and if he can take advantage them .... this very best to use the pick ... but not in the knowledge that the build file has a big role Thank you my brother ... so far tweek of assayed is the best

Brother should i put 3g tweaks in my j700f (4g) phone?
I m currently using custom LP rom by @Pavan l

GUI build prop

Well gang. I used root explorer to tweak build prop, but I've Ben getting apps closing down. Even tablet restarting its self! I reset tablet no change, flashed lollipop, no change, I'd like to know a default settings for the tablet. I used the following tweak,

echo "500" > /proc/sys/vm/dirty_expire_centisecs
echo "1000" > /proc/sys/vm/dirty_writeback_centisecs
can you tell me what to change kin. Order to change the apps from closing down so often or perhaps give the default prop?

Trying this Dirty Unicorn it has been great! just wondering if there is a build prop to help with the sudden restarts/ crashes?
