Get rid of CRT screen off animation in 4.2

[xaueious]

For some reason the CRT animation always has felt slow as sin, so I usually keep it off. Changing animation settings in developer options no longer works for some reason.

Workaround:

Put debug.sf.electron_frames=1 in either local.prop or build.prop.

echo "debug.sf.electron_frames=1" > local.prop

Remove this to re-enable. Default is 24 frames.

Requires reboot.

Steps:
Root required to do this. This assumes that you have no local.prop. If you do, you probably don't need this guide.

1) Get into adb shell
2) su
3) cd /data/
4) echo "debug.sf.electron_frames=1" > local.prop
5) reboot

Thanks for making this post. I'm a little confused though. Mostly by the "echo" portion. Mind explaining it in different terms?

My N7 doesn't have the CRT animation after updating to 4.2 I just figured they removed it.

It's that white line that 'folds' down into the center before disappearing when turning off the display.
Replicates what you used to see when turning off a CRT monitor/TV.

Personally I'm a fan.

Nexus 7 4.2 comes with a quick fadeout instead of the crt animation off.

my GN is not on stock so I can't report on it. i rather liked the crt off too, felt kinda neat.

Echo repeats whatever you type in quotes. The > sends it to local.prop file.

The key is to have the line in one of your props. Should work on all Android 4.2 AOSP builds. If it didn't work, Run 'getprop' from shell to see if the setting worked. If it didn't, you might have another script overriding it.

Also works on 4.1 but be careful how high you set it, hehe. I set mine to 72 and it worked, but wouldn't unlock again afterwards.

It's shown in getprop, but it still doesn't work. I hate this CRT effect, really wanna make it go away.

same thing here. I added it to build.prop, it is showing correctly on getprop but the effect is still there

push in search of a working method to disable this

I tried 'setprop debug.sf.electron_frames 1', and I was able to get [debug.sf.electron_frames]: [1] from 'getprop'. But, it is still not working.... help?

Update: I even try the app "build.prop editor" and manually create debug.sf.electron_frames (value:1), and it is still not working. I go to /system/build.prop, and yes debug.sf.electron_frames=1 is there. My phone is rooted, newly flash with stock 4.2 on Gnexus. It wouldn't because I have BusyBox installed, right?
