Root Debloating the stock system

I've been working on removing apps that I have no use for. I wanted to share what I've been able to successfully remove without killing the phone. This is not all bloat! Some of it is just stuff that I know I will not use, so why have it on the phone?

Warnings:
While both keyboards can be removed, doing so will cripple the stock launcher in safe mode (however, if you make another keyboard a system app, you'll be fine).
Removing LGATCMD Service and/or Software Update will prevent PRL/Profile updating.
Removing NFC Service will completely block NFC functionality.
Removing Qremote will disable use of the IR blaster. There are NO other apps that can be used on this phone at this time.

If you don't want to go through the whole list, a basic summary is that anything that you can re-install from the Play Store or LG App Updates and anything that the stock system will let you disable can be removed.

Another option is to run this debloat script:

Do you have any idea what dlna, multi photo and tags is for?
 
#2 donjuro, Sep 24, 2014
Never mind. Found out dlna is a sharing server and multi photo is a live wallpaper, but I still have no idea what tags is.
 
#3 donjuro, Sep 24, 2014
Multi-Photo lets you have a different wallpaper on each screen of your homescreen. Tags is for use with NFC stuff.

DLNA is that tap to share stuff...you know, because security isn't important. :p

***UPDATE*** - Did a factory reset in stock recovery fixed it.

I am now bootlooping. Disabled, stopped, cleared data and cache before uninstalling in link2sd. Next I cleared all app caches, cleaned up dalvik and rebooted now it's bootlooping (re-booting after boost mobile logo animation).

Why? What can I do now?

Everything worked fine EXCEPT, I could not move any apps to the real SD in link2sd. Partitioned with minitool and mounted 4ext.

The only app I uninstalled that is not on the above list was google search and that was yesterday.

**Currently rooted on v3 and have not updated**

Not sure what you did to your phone here, but it sounds like you're going to have to flash a new ROM. Have you tried booting without the SD card in? Having it formatting ext4 might be confusing it. ?

http://androidforums.com/volt-all-things-root/861292-how-restore-phone-dl-mode.html

Also, Google Search is listed above...it is included with 'All Google apps except Play Store and Services' ;)

When this bootloop happened I did remove the SD but same bootloop. After factory data/wipe in stock recovery it fixed the bootloop. I don't know what could of possibly happened inside the phone its brand new. The first thing I did was towelroot it bought a fresh new sdhc card , partitioned for link2sd and that's when I discovered my problem I didn't want: not being able to move apps to SD .

Also, im pretty positive 4ext is the only option for link2sd to work on the volt. This is what I need to do achieve .
 
#7 Complainter, Oct 26, 2014
ive noticed once i start removing apps that show up in the settings (like LG backup) my settings APK crashes. i cant open my settings menu. and the only thing that fixes it is a restore of a previous backup. ive tried reinstalling all the deleted apps and also tried reinstalling the settings app itself!!! debloating is giving me a friggin headache
 
#8 SPHM900, Dec 23, 2014
When removing system apps, your phone is likely to freak out occasionally. Clearing dalvik cache and the cache partition should resolve the issue (can be done in cwm). Sometimes a factory reset may be needed, depending on what you have removed.

Always proceed with caution when messing with your phone.

The reason removing things like LG Backup is whacking out settings is because its controls are provided within the settings app. Once you wipe dalvik and cache, the settings app will adjust to it being gone and not display the options anymore.

see i really want to download http://androidforums.com/threads/zv4-de-sprinted-and-de-lged-mostly.876451/page-6

however reading through it eduardog131 removed the activation app. im not so much concerned as about the radio, or totally bricking my phone because i have so many backups and ive basically perfected the V3 restore method lol. im just trying to figure out which APK to backup so i can insert it into his ZIP before i flash it

EDIT:

reread thru the post. downloading the new version now. little worried about radio problems as i have those with stock recovery. this is irreverent to this your tho lol

Fyi- the second list in this thread is everything that he removed from that ROM.
 
#12 bg4m3r, Jan 4, 2015
I'm posting here because I found a fix for an issue I had resulting from trimming a little too much...

One of the apps you listed:
-LGATCMD Service

and another you didn't:
-Software Update 3.0.0.0

I found out at least both of these are required to be installed in order to perform a PRL/Profile update. If you have Software Update and not LGATCMD Service, and try performing a PRL/Profile update you'll get an error saying "LGATCMD Service has stopped.". I restored the service (app only in Titanium Backup) and still got the error, but when I reset the cache+data in settings->apps->all it was fixed.

I'm not 100% sure but here's some other apps that I believe might be associated as well, but haven't tested if they're required:

com.lge.lgfota.permission
com.lge.permission
 
#13 phillk6751, Jan 7, 2015
Those are from the second list, which is what is removed from eduardogs ROM. I will add a note about that to the post. Thanks for the info. :)
 
#14 bg4m3r, Jan 7, 2015
So Removing these apps, we just delete them from the file system?
 
#15 Krisoliver8, Jan 10, 2015
Well, no, you should use something like Titanium Backup, Ultimate Backup, or Link2SD to uninstall them.
You also need to be careful because removing some stuff, particularly in the second list can remove some functions.
You need to be rooted as well, these are mostly system apps.
 
#16 bg4m3r, Jan 10, 2015
Alright, I wasn't sure, I don't know how much I'm gonna get rid of at this moment, I was just asking because there was nothing in the first post as to how we go about this(i.e. Programs or apps), and i don't recall in any of the other LG Volt root pages giving any reference to the tools we should use to "De Bloat". (I'm not being nit picky, just thorough for first timers like myself).

Also in my case as I stated in another LG Volt Root section I'm rooting an LG Volt that I have no Desier to use as a phone, are there any suggestions as to what phone functions could I remove without bricking it?
 
#17 Krisoliver8, Jan 10, 2015
The reason you won't find details like how to remove an app is because in the root forum, a certain level of familiarity is assumed. How to uninstall a system app is considered to be general knowledge, and if someone has to ask it lets us know you are very inexperienced or a complete novice. No disrespect intended, we all were completely clueless once, but it tells us you may need a little hand holding or extra explanation. In the mean time, it prevents you from driving your phone off a cliff.

Everything in the lists above can be safely uninstalled without bricking your phone. Some of the stuff in the second list will disable some functionality, like removing the LGATCMD app will disable PRL/Profile updating, which isn't a concern for you since you aren't going to activate it (it may have other negative effects that have not been noticed yet though). However, if you were to uninstall the NFC Service app, you will lose all ability to use NFC functions due to losing access to the hardware. The phone will still work, it just won't be able to do that anymore. Conversely, the DLNA app can be removed because it is just a protocol and can be replaced with a different app.

I add notes as issues arise so people know what to expect when they drop a given app.

Just be careful when removing apps. Make sure you know what it does, and if you aren't sure, either leave it alone, just freeze it, or make a backup of it before uninstalling.

Many of these app are tied into other apps or functions and suddenly removing them can make the phone freak out. Go slow, and if something starts acting weird, reboot and see if it stops, otherwise you might have to wipe the system cache and/or dalvik-cache, or do a factory reset.

So dumb question that maybe someone knows the answer to:

I finally rooted my volt to zv5 and came to this thread for debloating advice. After the removal of what I considered unnecessary programs with system app safe remover, I no longer have the ability to switch fonts in system settings>display>font type. I tried other methods of changing fonts, like the apps ifont and Hifont, but neither change nearly as much text font as the stock font settings. Which program did I delete that did this, and can I redownload it? Or maybe I didn't have that option to begin with in zv5?

TL;DR: rooted, debloated, can't change stock fonts. What do wrong?
 
#19 bumpymind, Jan 21, 2015
Probably fontserver.apk
 
#20 kwknott, Jan 21, 2015
Unfortunately it isn't that apk, I still have that one downloaded. Could someone confirm that this functionality works on their version of zv5? I don't want to reflash if it doesn't work to begin with.
 
#21 bumpymind, Jan 21, 2015
I dirty flashed over zv4 I can still change the fonts
 
#22 jothe 1, Jan 21, 2015
