Noticed none of the current builds have the CRT animation enabled, thought I'd share how to turn it on. Please note that it is at times a bit buggy. For me it works about 8 out of 10 times.

What it is:

Note: 1 - This will work on any device and on any version of Android back to GB. (Obviously the Nexus specific tools wont work on anything other than the Nexus)

Note 2 - You will have to redo this every time you update your rom.


Here's the quick rundown -

First, you'll have to pull the framework-res.apk from your tablet.

This can be done via adb, but the easiest way would be to either use WugFresh's Nexus Root Toolkit or mskips Google Nexus 7 TOOLKIT.

When asked what file to pull, type in "/system/framework/framework-res.apk" (without quotes)

Once you have that pulled, install this tool: http://forum.xda-developers.com/show....php?t=1432152

Follow the directions on how to use it in the thread.

Once you have decompiled the apk, you'll want to edit the "files-to-edit\framework-res.apk\res\values\bools.xml" file.

The value you want to change in the bools value is the "<bool name="config_animateScreenLights">true</bool>" change "true" to "false". I reccommend downloading Notepad++ to edit.

Make sure you save it. Once saved, recompile the apk using the tool you install, then create an update zip (I renamed mine to crtanimation.zip for ease).

Reboot into recovery, flash the zip, clear cache, reboot.

Tada!

Why would someone want to put a custom rom on N7?

They most likely don't know what CRT animation is, NOT why they might want to make changes to the system.

Nothing in the OP provides a hint as to what that is or what it does. To be honest, I'm not sure I know what it is. A quick search shows that it is enabled in a lot of ROMs but not what it actually is or does.

OK, makes sense, I was assuming most knew what it meant.

I'll make a quick video.

Just made a video, uploading it.

If you don't know what it is then you obviously haven't flashed many roms and therefore should probably not even attempt this...

Thanks OP and sry for the ungrateful ones here.

updated OP with a demo vid

I guess the CRT animation is more obscure than I thought.

Okay... I get it... It enables animation effects when turning the device off, rather than just blanking the screen.

I get the same effect turning on and off with
https://play.google.com/store/apps/d....turnoffscreen

You can select from a number of effects, sounds for both when the device is turned on and off via the button. You have to hit the button for it to do it, but for the risk of modifying system files, this is easy and safe to do.
