How to permantly Disable dynamic fsync??

How can i permantly disable dynamic fsync??? with a init d script or something... but DONT tell me any app plz

Run Terminal Emulator in Root and Enter:
Disable:
su
echo 0 > /sys/kernel/dyn_fsync/Dyn_fsync_active
Click to expand...
Click to collapse
Enable:
su
echo 1 > /sys/kernel/dyn_fsync/Dyn_fsync_active
Click to expand...
Click to collapse
Setting/value will be lost after reboot..
Or:
1) By downloading and using Trickster MOD
2) By directly editing the file /sys/kernel/dyn_fsync/Dyn_fsync_active and setting 1 to enable the dynamic fsync, 0 to disable it (note that set value will be lost after a reboot/shutdown)

ye i know that ways... ty anyway.. but if i make a init.d script with "echo 0 > /sys/kernel/dyn_fsync/Dyn_fsync_active"? or something with busybox?

[Q] How can I disable the LED while charging?

Hello XDA-developers
How can I disable the LED while charging?
I have root access on my Huawei ascend P7.
Lightflow (lite) doesn't help, and Settings > Display > LED and disable it there doesn't help too.
Thanks for your help.

Hello !
Here it is :
Code:
> adb shell
$ su
# echo 0 > sys/devices/platform/hkled/leds/green/brightness
# echo 0 > sys/devices/platform/hkled/leds/red/brightness
# exit
$ exit
Good luck !

Hey surdu_petru, what options else are there? You say echo 0 with output at red and green....can i find the options somewhere?
My red and green/red files are on zero but i have light at charging.

I tried that now under Lollipop, but it doesn't survive a reboot. When only setting brightness to zero, the light returns after un- and replugging. So, I set the rights to -r--r--r--, now it works until reboot.
There is also a file called trigger, which I can't change at all, although the rights are -rw-r--r--. I could save, but when opening the next time, it is like it was originally.
Does anyone have an idea how to make those changes permanent? Might the reset be caused by the kernel?

How to run a script?

How can I run a script with the code that I will give on kitkat , because my touchscreen get unresponsive and this script should fix it?
#!/system/bin/sh
echo 20 > /sys/devices/i2c-3/3-0024/main_ttsp_core.cyttsp4_i2c_adapter/finger_threshold
chmod 666 /sys/devices/i2c-3/3-0024/main_ttsp_core.cyttsp4_i2c_adapter/signal_disparity
echo 0 > /sys/devices/i2c-3/3-0024/main_ttsp_core.cyttsp4_i2c_adapter/signal_disparity

What's the fastest ROM to date?

Finally got a new battery after over a year of not using my Droid 4.
Flashed latest CM13 nightly, 1.4ghz OC. Everything seems slow.
My 512mb ram single core $19 cheapo runs smoother.
Anything I do has a half-second or so delay, clean install with nothing running in the background.
Ideally I would just go back to some minimal 2.3.7 ROM, but compatiblity for new programs is getting iffy.
So, as of 2016, what has the smoothest ROM to do date been?

I'm running very, very debloated, overclocked stock JB 4.1.2 with Greenify and ram manager and it works pretty well. Even most of new games and emulators rund good.

Cyanogenmod 11 is quite good. One thing I noticed is that the virtual ROM slots are extremely slow, due to the loopback devices.
One way to go is to install the ROM to the virtual ROM slots to test if they are working correctly and then install it into stock slot for real use.

Up, same question here

I use cm11 or cm12 (i find cm13 extremely slow) But with the following tweaks made from my daily experience feel free to try it

Thank you man, this script made my droid 4 a whole lot more responsive and it does not reboot every few hours anymore.
Quite a few commands in that script don't work, probably due to different paths (sio plus as io scheduler and stock rom boot slot), but those that work, really seem to help a lot.
Oh and you should update the comment in that script about the zram size.

Was testing on different Kernels that's why the paths are wrong.. Please replace the sio plus with cfq or bfq (i forgot to change that)
I am glad that those tweaks help you

What about this one? Mentor's ROM http://forum.xda-developers.com/showthread.php?t=2122709
That's what I found on my used Droid 4... should I give it a try?

why replace sio plus? I used bfq before, but when i googled for sio plus i only found people saying that sio plus was the best of them all.

If your kernel support sio plus, of course use it.. else cfq or bfq is a good alternative

What am I supposed to do with these lines? And can somebody please explain what they are doing specifically?
I was trying to find a way to enable zram to cope with the small amount of memory. swap ram is an alternative, but i heard zram is faster and not stressing the storage like swap ram would.

No one with a basic guide

Do you have ROOT?
If not, you can"t auto turn on UPSM.

Yes I have root

@bandit250
you are still interested?

Yes please

First, Make a test.
Task:
1. Run shell [mark ROOT]
Command:
echo "2" > /sys/devices/virtual/mdnie/mdnie/accessibility
Push play
upsm should turn on.
