[MOD] Poor streaming performance-AAC audio fix

There was one hack i really enjoyed.....from my Nexus is the Fix poor AAC streaming performance http://forum.xda-developers.com/showthread.php?t=737111&highlight=stagefright
Code:
C:\Users\Mikey\Desktop>adb shell
$ su
su
[COLOR=Red]Watch your phones screen for superuser asking for permission, it you have not granted it in the past.[/COLOR]
# busybox mount -o rw,remount /system
busybox mount -o rw,remount /system
# cp /system/build.prop /sdcard/
cp /system/build.prop /sdcard/
[COLOR=red]I use root manager at this time to edit the file while on the phone, long press on the file and open in text editor.[/COLOR]
From: [B]media.stagefright.enable-player true[/B]
To: [B]media.stagefright.enable-player false[/B]
# cp /sdcard/build.prop /system/
cp /sdcard/build.prop /system/
# busybox mount -o ro,remount /system
busybox mount -o ro,remount /system
# reboot
reboot
C:\Users\Mikey\Desktop>
When the phone reboots run Visionary, for root. http://www.appbrain.com/app/visionary/com.modaco.visionary
In my case i use Enomthers Rom, located here:
http://forum.xda-developers.com/showthread.php?t=806612
In terminal, granting su permission first, then type:
Code:
/data/local/tmp/startrom
Of course you need the proper files in the tmp folder to run Enomthers rom.

can you give info on the changes to prop?! Would like to test this on my nexus and g2 when u get it figured out.

How can i disable auto brightness on Cyanogen Mod 7.2.0?

Hi! I have installed Cyanogen mod on my Xperia Play. Run nice, but i can't find how can i disable automatic brightness. Is it normal or i can install it again?
Thanks in advance!

I Find solution:
Do you need root explorer and a terminal emulator.
* Go to system/etc on root explorer and switch R/O
* Open Terminal and Write:
su
mount -o rw,remount -t yaffs2 /dev/block/mtdblock0 /system
echo "echo 0 > /sys/devices/i2c-0/0-0040/leds/lcd-backlight/als/enable" >> /etc/hw_config.sh
echo "echo 254 > /sys/devices/i2c-0/0-0040/leds/lcd-backlight/brightness" >> /etc/hw_config.sh
echo "echo 254 > /sys/devices/i2c-0/0-0040/leds/lcd-backlight/max_brightness" >> /etc/hw_config.sh
Click to expand...
Click to collapse
* Reboot and done.
With it you disable sensor and set brightness to max.

i had the same solve it with this app Brightness Level

I used this: https://play.google.com/store/apps/details?id=com.hatcyl.android.Disable_Auto_Brightness&hl=nl

Thanks forma the apps!

Sgs3 cm10.1 ums rooted (ext4 xfat)

Hi all,
since i could not use the UMS mode on my sgs3 and all of the tested Applications do not work i made 2 scrips for gscrip.
First check if all mount points are correct for you, if not correct them. Run mount, check mount point of sdcard (/dev/fuse /storage/sdcard1)
But i think on all sgs3 with cm10.1 it should be the same.
edit:
I get a transfer rate of ~8.5MB/s writing and ~ 18MB/s reading so for copying mp3 to the mobile i will still plug the card to the pc.
!!! AND DON'T FORGET TO UNMOUNT/EJECT YOUR SDCARD BEFORE ums_off !!!
And don't forget you are working as root so you can screw up a lot

ums_on
Code:
setprop persist.sys.usb.config mass_storage,adb
umount /storage/sdcard1
echo /dev/block/vold/179:49 > /sys/devices/platform/s3c-usbgadget/gadget/lun0/file
ums_off
Code:
echo "" > /sys/devices/platform/s3c-usbgadget/gadget/lun0/file
setprop persist.sys.usb.config mtp,adb
vold
Hints:
If you are using Linux and your sdcard is ext4 like mine and can't write as a user to the root of the sdcard just add a group to "/etc/group" for me it was (the id you see when you type mount)
Code:
mobile_sd:x:1023:dark-wulf
Check and Disable journal on ext4 sdcard with a card-reader
Code:
root # tune2fs -l /dev/sdXY | grep has_journal
root # tune2fs -O ^has_journal /dev/sdXY
And remove reserved blocks for root
Code:
root # tune2fs -m 0 /dev/sdXY
Thanks to http://forum.xda-developers.com/showpost.php?p=27282116 for bringing me the idea

(GUIDE) SELinux Permissive/Enforcing

SELinux Permissive/Enforcing mode changing with Termux linux terminal android.
Use root mode
$ su
(Give root access termux)
Show what mode SELinux use now
$ getenforce
Set SELinux
$ setenforce 0
(Permissive)
$ setenforce 1
(Enforcing)

Here's a magisk module that sets SElinux even after reboots, it incorporates the commands but sets them everytime the system boots. I posted a modded version of the module if u want SElinux to enforcing instead of permissive and it actually works great
[MODULE] Debugging modules: ADB Root, SELinux Permissive, Enable Eng
These modules are not meant for everyday use. They are intended for debugging and modification of a firmware. They significantly lower security of your device while active and even could softbrick it. You've been warned. ADB Root Magisk Module...

Why? What error do you get?
Try to move/copy something into /tmp folder. It should work if you're rooted (your shell shows # instead of $).
If it doesn't work, maybe you have to remount your system as rw (read and write):
Code:
mount -o rw,remount /
after you made your modifications, mount it as ro (read only) again:
Code:
mount -o ro,remount /
If it still doesn't work, we need to see the error you get (copy and paste into this forum) while moving/coping something into /tmp.

Can you verify you entered that command as root?
Please do the following:
Do this on your computer to enter your devices shell
Code:
prompt_PC:~$ adb shell
Code:
prompt:~$ whoami
This should give you either "shell" or "root"
If it says "shell" do:
Code:
prompt:~$ su
prompt:~#
It will show a # instead of $ if you're root.
If you're already root (or you are now root due to su command), do:
Code:
prompt:~# mount -o rw,remount /
Now it should be writeable and you can do your modifications.
After you finished you need to change it to ro (read only) again:
Code:
prompt:~# mount -o ro,remount /
After that you can exit the shell:
Code:
prompt:~# exit
prompt:~$ exit
(first exits su, second exits shell)
I'm sorry if you already did that but I wan't to be sure you did it correctly.
If this procedere doesn't work, please copy and past your input and output into this forum as this might help to understand what's going on/failing etc.
