Manually removing the parts, sure. There's no quick way such as dd'ing a clean system because the only way to get a copy of the system is to be rooted to have access to it. Unless someone has done that and then edited the resulting image manually of course.

 

adb can't flash a phone, it can restore backups but those backups aren't a complete rom. You'd need fastboot to flash /system. It may be possible to do it with root using dd on the phone but I wouldn't try that as you'd be writing to the partition you're using to write to the partition with, the results of which could be... interesting.

Why do you need to do this? Is the phone in a nonfunctional state?

 

Spoiler

Looks straightforward enough. I cooked up a script for someone to remove the 4.2 camera/gallery and put back stock, I can whip something up for you for this if you'd like.

I assume you're rooted, how else would you have installed it in the first place.

edit: There may be an easier way than that, get a stock copy of /system/etc/audio_effects.conf and replace the one on your phone with it, and then delete DSPManager.apk from /system/app. You'll need to mount /system writable for it of course. The rest of the DSP Manager can be left on the phone, they won't do anything anymore when the .conf isn't loading them.

I'd attach the conf file but I'm getting complaints from the forum that I'm over an attachment quota.

 

I updated that reply with alternate instructions. Since the forum won't let me upload a file I'll just put it in this reply hidden, copy it and save as audio_effects.conf

Spoiler

Let me know if it works, if it doesn't then I'll do it like I was going to before.

 

Done it. It sets the phone into a bootloop with no way out.

 

I'm kind of happy for you then. What didn't work?

 

Maybe, but I'd have to wonder just how good a bassy song sounded in the first place...

 

Before doing that, delete /system/vendor/etc/audio_effects.conf and reboot. Note that this is not the same file you replaced earlier.

Just for shits and giggles go ahead and delete /system/lib/soundfx/libcyanogen-dsp.so as well. After that, along with the earlier instruction to replace /etc/audio_effects.conf and nuke DSPManager.apk there won't be anything left of the CM DSP manager on the phone.

 

It kind of depends on the file you're wanting to push or pull. ADB stands for "Android Debug Bridge" and that's basically all it is, it's got some neat tricks but most of it could be done the same with some creative shell scripts and SSH access to the phone. It's kind of a glorified version of that, providing a conduit in to the built-in shell of the phone, same thing you see from a terminal app really. For instance I can tell you "adb reboot" reboots the phone, but if you type "reboot" in to a terminal on the phone itself it'll do the same thing.

Telling you the specific commands for what's already been done now won't be of much help, you'd be better served by playing with adb yourself and learning it that way.

 

With ADB yu need to be on the computer and it always starts with adb then follows with the command. I know some people dont give a straigh answer, it was the same with me so here it is:

adb pull:

Open Command Prompt (windows)

Type adb connect(if it says device not connected or offline, etc then yu need to remount it)

Adb pull /"folder name"/"folder name"/"keep repeating til yu get to desired file destination"
I.e. adb pull for System UI: adb pull /system/app/systemui.apk


Adb push:

Open Command Prompt (windows)

Type adb connect(if it says device not connected or offline, etc then yu need to remount it)

Yu need to put the destination of the file yu are pushing into the command prompt,
I.e. trying to push systemui.apk thats on yur desktop to the phone yu would need to type:
cd C:/Users/"name of yur folder which yu are under"/Desktop

After that it should be mounted, so now yu can push the file by typing in the command prompt the destination of the on yur computer, add a space and the destination yu want to put it on yur phone. If yu are on the correct path, yu can type the first four letters of the name of the file then press tab, this should finish naming the file yu are trying to push.
i.e.
adb push systemui.apk ./system/app

hope this helps and can be understandable..
