I purchased an LG Viper LTE (refurbished) from FreedomPop and have spent a bit of time playing with it and determining its capabilities and limitations. I want to have a central repository of knowledge regarding this phone. Some of this may overlap with other devices (LG or other), so I will try to provide links where they make sense. I intend to update this thread as I learn more information.
The phone I received came with LG's LS840ZVK (Android 4.0.4 - ICS) firmware, with a few custom apps that FreedomPop has installed, and a ton of bloatware from both Sprint and LG.
Rooting: (I started with a similar guide and forged my way from there.)
Downgrade your Viper (from version LS840ZVK to LS840ZVI). This will also perform a factory reset.
Root the phone after the downgrade (with the Bin4ry Root tool - If you use Bin4ry v36, use option 3, "New Standard-Root").
Backup root (with Voodoo OTA RootKeeper).
(Connect to WiFi and) Apply the System update (your phone will notify you about this - it has an OTA update for you to install).
Since the OTA update did not wipe (factory reset) your phone, use the Voodoo RootKeeper app to restore your root.
I also updated my Profile/PRL (in "Settings > System Updates"), and I believe this restored my 3G/4G data connection.
For FreedomPop, make sure you install the FreedomPop Messaging app to connect your device to the service.
Bootloader:
Unfortunately, I have not been able to unlock the bootloader. Perhaps, if I downgraded the phone to a pre-ICS firmware, I could do so, but I have not tried that yet.
System trim: (requires root)
I mentioned that the phone came with a bunch of bloatware, which seemed to cause tremendous unnecessary battery drain. With root, I was able to remove many of the junk apps. (Make sure to mount the /system partition as writeable: mount -o remount,rw /system) The list of stock apps I removed:
CameraTestApp.apk
CameraTestApp.odex
LGEmail_Native.apk
LGEmail_Native.odex
LGExchange.apk
LGExchange.odex
MLT.apk (some LG debug app that reports data back to LG and drains battery like crazy)

SprintHiddenMenu.odex
SprintID.apk
SprintID.odex
SprintMusicPlus.apk
SprintMusicPlus.odex
SprintNASCAR.apk

SprintNBA.apk

SprintVVM.apk (Visual Voicemail)
SprintVVM.odex
Sprint_Installer.apk
Sprint_Installer.odex
Tag_na.apk

WIFIOffload.apk (Sprint Connections Optimizer - removing this will cause Settings to crash when you navigate to "Settings > More... > Mobile networks > Connection optimizer", so remove only if you can live with that)
WIFIOffload.odex
Zone-Sprint.apk
Zone-Sprint.odex
LG has not only locked their bootloaders on their newer phones, but has also implemented some system check on every boot, so you must TAKE GREAT CAUTION when attempting to trim your system. If you remove an app that the software deems system essential, your next boot will result in a "Security Error", past which you cannot boot. To recover from this, you will have to reflash the firmware. (See the "Rooting" section; whenever I have put my system into this "Security Error" state, I have just downgraded my system and started the rooting process all over. In any case, you will lose your data.)
I don't know which app caused it, but removing one of the following apps will result in a "Security Error":
BooksTablet.apk
BooksTablet.odex
Magazines.apk
Magazines.odex
Talk.apk
Talk.odex
Videos.apk
(I remove apps by moving them into a backup-type directory, and then I can restore them by copying the files back to the /system/app directory.)
Minor annoyances: (I would hope eventually to resolve all of these and indicate the solutions in "Tips and Tricks".)
Camera shutter sound: I cannot select a silent setting for the camera shutter sound. I have I identified /system/media/audio/ui/shutter4.ogg as the most annoying of the four tone options, and have tried removing this file, or replacing it with an audio file of silence to no avail. Perhaps the camera app stores the audio within the app itself. I could download another camera app, but I'd rather not.
Polaris Office: I cannot remove it. It appears as a system app, but I cannot find any file that provides this app, either in /system/app or /data/app. I extracted all of my system apps, and ran a search for "polaris", and only LGHome3.apk had any match. Perhaps LGHome3 contains this app as well, which would mean I would have to reverse-engineer the app in order to remove Polaris Office.
Tips and Tricks:
Silencing the startup/shutdown animations: I located the files for the animations and simply removed them, rather than keep them and do something to silence them. The /system/media directory contained both files for the boot (bootanimation.zip) and shutdown (shutdownanimation.zip) animations, and I removed both of these files.
[Reserved for future updates]
Kingo Root
I rooted with Kingo Root and did not have to downgrade to LS840ZVI. I removed all the Sprint apps but removing any of the Google apps will apparently result in the security error. Better to freeze the stuff you don't need.
Reflashed LS840ZVK rooted and started over again.
Kingo Root works
I also used Kingo Root successfully. I removed most of the apps listed in this guide with the exception of Google apps. Instead of using OTA Rootkeeper to preserve root, I used Super SU Pro, which has a survival mode.
Magazines is not one of the apps that will cause the security error. It is either Books, Movies, Music, or a combination of the three. Additionally, if you do use any of those apps, and you integrate the updated APKs into the ROM, it will cause a boot error as well.
hi can i ask if there is still link for ls840zvk manual firmware? I am having security error on boot thanks guys.

On the german "android-hilfe"-forum the users managed to delete the default apps from the system/app folder. I'm going to translate it to english and post it here. Original thread: android-hilfe.de
All changes are done at own risk. I'm not responsible for a bricked phone. If you don't know what you do, stop reading here.
First of all you need to root your mobile: [HOW TO] Root Motorola Defy.
If you rooted with z4root: you need the androidSDK to go on with the next steps. So have a look at the link above and get the tools and information need to go ahead.
After that you need to:
1. type in the command line on your PC
Code:
adb shell
2. now you need to get super user rights:
Code:
su
3. you need to remount the system partition
Code:
mount -o rw,remount -t ext3 /dev/block/mmcblk1p21 /system
4. change to the /system/app directory and you can now rename/delete all files in there
I hope you make a copy of this folder, so you can always revert back to factory default. A hardreset doesn't restaure the deletet apps, so be carefull. Also you need to check on your own IF you can really delete a app or not. I don't know what features you use.
Successfull deletet apps:
- amazon
- adservice
- arcphotoworkshop
- arcvideoeditorlite
- bluremail
- blursnmessagingengine
- blurupdater
- cardock
- contactsunconnected

It will be great!
is it posible to replace any of the "blured" apps?
Code:
BlurAlarmClock - AlarmClock (whats special with blured AlarmClock?)
BlurCalendar - Calendar
BlurContacts - Contacts (I only want google contacts and groups)
BlurEmail - Email (what's the difference between default?)
BlurHome - I Assume this is MotoBlur launcher (Wild Guess; it's really bad idea to remove this)
BlurPhone - Dialer?
is it posible to stop services from starting?
I have this services started, I have removed ALL widgets on ALL motoblur-homescreens and rebooted my phone and using ZeamLauncher. Still I have a few services started that I don't like to have started.
FeedReciverService - Social networking (com.motorola.blur.friendfeed)
WeatherService - Weather (com.motorola.blur.home.other)
Click to expand...
Click to collapse
Considering the name of the services I don't use them. I have no Social Networking stuff on my phone and no weather widget.
When and where do services start? if apps can start services when needed (I assume they can) is it posible to track down which services an app starts?
Ok, a couple of noob-ish questions here...

Ok, so now we seem to have jumped forward a bit.
I assume by command line we're doing this on a PC, right?
If so, is there a particular mode I should select when connecting the handset?
And one last one - you list 'adservice' as something that's safe to remove, does what I suspect and kill off adverts on the handset?

If you used the rooting method I've linked to, there wouldn't be a jump
Anyway you are right, its the command line from the PC. But you need the androiSDK for this commands. The adb.exe can be found in the tools subfolder. Go to the rooting method I've linked to and just get the infos missing here.
I don'T think that adservice will kill ALL your ad's on your phone. Those are included IN the games or apps. Have a look at adfree on the marked. This will work on your rooted phone.
Thanks for your respond...I've changed the first post a little bit.
deleted most of the stuff above...

U did the remount? If not, follow all steps again. If you tried to access /system/app directly from you phone with a filemanager: it won't work until you use rootexplorer (payware).
You can use Titanium backup too (free)
Amazing how responsive the phone becomes after removing some of the bloat.
Interesting Topic, is this about deblurring or are there any more Motoblur Tasks running in the Background after the process?
I really want to get rid of Motoblur, (in my opinion it is just useless Crap running in the Background and collecting data) but I would still like to have my Android Updates. Is there any way to do this?
For you guys who have been de-bluring your phones which apps have you removed? It would be interesting to know which apps that are safe to remove and which that are not or have dependencies to other blur-apps. Thanks in advance!
Probably there's only a try and error you can do. I'e posted a list of apk's which are save to remove without going into bootloops. But there's no garuntee that this meets ALL your whishes of services to remove or to stay.
I think that you can give jboogie a try. Also you can try to make a nandroid backup befor starting to remove things. A titanium backup won't help, as it won't backup your system APKs. Don't rely on this.
If you miss a APK (cause you deleted it to fast) feel free to ask, I copied mine all to my SD Card.
Titanium backup will back up the data (edit: not apps) to your SD card and won't restore them to the system/app folder. (so be warned)
Personally I went for:
ESMusica (Didn't notice any difference)
HipHopOfficial (Didn't notice any difference)
TrueCountry (Didn't nitice any difference)
Social Networking 2.1 update 1 (big speed boost)
Social Status 2.1 update 1 (big speed boost)
Social Messaging service update 1 (big speed boost)
Social Messaging update 1 (big speed boost)
AmazonMP3 (nice speed boost)
News 2.1 update 1 (nice speed boost)
Weather 2.1 update 1 (nice speed boost)
CarDock 1.0 (Didn't notice any difference)
Sticky note 2.1 update 1 (Didn't notice much difference)
Browser Message 2.0.2 (Didn't notice much difference)
Connected Music player (nice speed boost) - Spotify + powerAMP user
At this stage the phone was running lag free, so I don't bother with anything else. (esp with custom ROMS on the horizon back then )
Sounds very interesting.
Would be really great if someone could put together a real Noob Tutorial.
I am not familiar with ADB
Here's what I renamed. I just changed the .apk file extension to .fix (just something easy to remember if I want to do a search and change them back)
AdService
ArcPhotoworkshop
ArcVideoEditorLite
blur-services
BlurDemo
BlurEmail
BlurEmailEngine
BlurSNMessagingEngine

I have not experienced any problems yet. If I do I'll post what I find.
can i get some help here? how exactly do you change to /system/app? is it as simple as typing "/system/app"? and then what happens does ADB list all the files in there or is there another command you ahve to use?
HOW TO REMOVE BLOATWARE
Step 1. Root your phone using one of the two methods listed here
ROOT YOUR LG G3
Step 2. Download and install Root Explorer
Play Store
Step 3. Create the following file structure on your internal or external SD CARD
Main Folder: RemovedApps
Sub Folders in RemovedApps:
APP
PRIV-APP
VENDOR
Sub Folder in RemovedApps/Vendor
APP
This step will give you the following folder structure
RemovedApps/APP
RemovedApps/PRIV-APP
RemovedApps/VENDOR/APP
Step 4: Open Root Explorer and use the firs tab to navigate to root/system/ (NOTE: Root Explorer will ask for SuperSU permissions - make sure to give it permission) and the second tab in Root Explorer to Navigate to your newly created RemovedApps Folder
Step 5. use the following list to cut and paste the listed files from your system folder to the RemovedApps Folder NOTE: remember to copy files to corresponding folders IE system/app to RemovedApps/APP and System/vendor/app to RemovedApps/Vendor/APP NOTE: once you try to cut the system files, Root Explorer will ask if you are sure you want to modify system files - say yes

Step 6: To be safe, copy your RemovedApps folder to your computer for backup
Step 7: Reboot phone
WARNINGS & DISCLAIMERS
Proceed with caution and at your own risk - I am not responsible if your phone self destructs, gets bricked, or melts.
Please keep in mind that both these methods will yield ROOT only - as of know there is no way to unlock bootloader on AT&T
Rooting and any other modifications to your phone will void your warranty - do not root if you do not know what you are doing.
Rooted devices will not be able to receive OTA updates. You may have to unroot and restore stock in order to accept updates.
Frequently Asked Questions
FAQ:
Q. Why do I need to be rooted to do this?
A. Because you will need access to the root and system folders.
Q. Why De-bloat my phone?
A. The manufacturer and the carrier install a bunch of branded apps that take up space and resources. By uninstalling these apps, you have less background activity, less space used and more resources to use for the apps you do want.
Q. Can I use Titanium Backup to Freeze these apps?
A. Freezing these apps will work, however freezing these apps does not free the space used by these apps.
Backup of Removed Files
Backup zip of Removed Files
Did you not follow the directions in the OP?
Did you just decide to delete everything instead of backing it up?
Are you trying to find the .apk for one of the apps you deleted?
Well you are lucky! Here is a zip of everything I told you to backup and remove!

There is no issues with removing LADDM.apk - it is CarrierIQ. It will not allow CarrierIQ to work - if you'd like you can also follow the removing CarrierIQ instructions and remove the lib files and disable everything in android tuner to completly get rid of everything. Either way - no adverse reaction to removing it... in fact its better to have one less thing stalking and tracking everything you do with your phone.

Try clicking on Mount R/W and it should ask for root permission.... Give permission and proceed... Also check to make sure you have SuperSU installed... If not installed then download from playstore, run, and reboot... Then try again

Thanks for putting up this how-to. I went ahead and followed the instructions to the "T", and then rebooted. I am a little confused as to why some apps still showed up in my app draw even though they were properly cut and moved to the new folder? I went ahead a tried clearing data for "home" to see if they would show when reloaded, however they still appeared. There were about 5-6 apps including twitter, ISIS, Lookout, and a few more than I forgot the names. I went ahead and manually removed them from the app draw, however I was wondering why they didn't disappear like the others did??
Thanks for your help!

Its probably because you had already updated these apps through the playstore... Just go to playstore and you should be able to uninstall them like any other app.

Hello everyone
I am not a developer but would appreciate any helpful feedback, preferably in layman's language, that anyone might be able to offer to a problem that I am having with my android device, running version 4.2.2, a large Hannspree 13.3 tablet. I bought the tablet about six months ago and I am happy with the general performance. However, recently I downloaded a number of streaming media apps from Google Play Store including the Sky Go and Sky Movies apps and also the All4 Channel 4 on demand app. When I tried to run these apps, I got a message saying 'These apps are not supported on rooted devices'. I am led to believe that the Hannspree 13.3 is rooted by default at manufacture although I did not know this at the time of purchase and indeed, at that time I was totally ignorant about 'rooting'. For this reason, I have not yet opted to do a factory reset of my device because, if true, then this would not solve the issue. After researching comments on a number of internet forums, I came across several suggestions as to how to resolve the issue. I opted for downloading the SuperSU app, which then enabled me, via the app settings, to perform a 'full unroot', which I duly did. By downloading a root checker app, I was able to verify that my large Hannspree tablet is now unrooted. However, when I tried the Sky Go and Sky Movies apps after unrooting, I still got an error message 'Not supported on rooted devices'. I no longer get the 'rooted app' message when I play the All4 app, but the app doesn't play, it simply hangs. Therefore, and I have been in touch with the Sky Community forums, these streaming media apps all still perceive my device to be rooted but it is not, although someone from the Sky Community forum suggested that there still must be traces of the original rooting in the OS/firmware which the Sky apps and other streaming media apps are picking up on. I tried, on advice, a hide root app but when I tried this, I get a message saying 'Cannot find the su binaries'. When I tried to reinstall SuperSU I got a similar message 'Cannot locate the su binaries and SuperSU cannot install them. This is a problem'. It seems that the original unrooting has removed the su binaries and I cannot now try hide root apps. However, there must be some trace of root that the streaming media apps are still picking up on.
Would anyone know how to remove these traces of root. I did read somewhere, another suggestion from a forum, that it was possible to manually unroot a device by using a file manager app and deleting su binaries from system/bin and system/xbin directories and deleting superuser.apk from system/apps directory. However having browsed system directory with root browser in the ROM toolbox app, the su binaries are not present in the system/bin or system/xbin which, I suppose, is further verification that my device is now unrooted. But it can't be fully unrooted, otherwise surely the streaming media apps would play.
Should I do a factory reset to restore the device to its default (presumably rooted) state and then manually delete the su as described above?
The curious thing is that the streaming media apps work perfectly on my smaller Hannspree 10.1 device, which obviously is not rooted and not perceived as rooted.
Is it possible to install the operating system of my smaller Hannspree device onto my larger Hannspree device? I tried the 'check available updates' in the About tablet tab in Settings but I get an error message on my large Hannspree device to the effect of 'Error invalid ROM ID' so cannot do an update, or check for an update.
Can any of you techies out there help?
Thanks, in anticipation.

Hello everyone
I am not a developer but would appreciate any helpful feedback, preferably in layman's language, that anyone might be able to offer to a problem that I am having with my android device, running version 4.2.2, a large Hannspree 13.3 tablet. I bought the tablet about six months ago and I am happy with the general performance. However, recently I downloaded a number of streaming media apps from Google Play Store including the Sky Go and Sky Movies apps and also the All4 Channel 4 on demand app. When I tried to run these apps, I got a message saying 'These apps are not supported on rooted devices'. I am led to believe that the Hannspree 13.3 is rooted by default at manufacture although I did not know this at the time of purchase and indeed, at that time I was totally ignorant about 'rooting'. For this reason, I have not yet opted to do a factory reset of my device because, if true, then this would not solve the issue. After researching comments on a number of internet forums, I came across several suggestions as to how to resolve the issue. I opted for downloading the SuperSU app, which then enabled me, via the app settings, to perform a 'full unroot', which I duly did. By downloading a root checker app, I was able to verify that my large Hannspree tablet is now unrooted. However, when I tried the Sky Go and Sky Movies apps after unrooting, I still got an error message 'Not supported on rooted devices'. I no longer get the 'rooted app' message when I play the All4 app, but the app doesn't play, it simply hangs. Therefore, and I have been in touch with the Sky Community forums, these streaming media apps all still perceive my device to be rooted but it is not, although someone from the Sky Community forum suggested that there still must be traces of the original rooting in the OS/firmware which the Sky apps and other streaming media apps are picking up on. I tried, on advice, a hide root app but when I tried this, I get a message saying 'Cannot find the su binaries'. When I tried to reinstall SuperSU I got a similar message 'Cannot locate the su binaries and SuperSU cannot install them. This is a problem'. It seems that the original unrooting has removed the su binaries and I cannot now try hide root apps. However, there must be some trace of root that the streaming media apps are still picking up on.
Would anyone know how to remove these traces of root. I did read somewhere, another suggestion from a forum, that it was possible to manually unroot a device by using a file manager app and deleting su binaries from system/bin and system/xbin directories and deleting superuser.apk from system/apps directory. However having browsed system directory with root browser in the ROM toolbox app, the su binaries are not present in the system/bin or system/xbin which, I suppose, is further verification that my device is now unrooted. But it can't be fully unrooted, otherwise surely the streaming media apps would play.
Should I do a factory reset to restore the device to its default (presumably rooted) state and then manually delete the su as described above?

Hi, thank you for using XDA assist.
There is a general forum for android here*http://forum.xda-developers.com/android/help*where you can get better help and support if you try to ask over there.*
Good luck.
I was installed some s8 random apps (downloaded from appmirror) by the following tricks from this forum.

These are the steps I done
1. Add a shortcut of the apk to the home screen from the my files app
2.Power off the phone.
3. Cleared the cache partition.
4. Restarted the phone.
5. Quickly installed the Apk by accessing the shortcut from home screen.
(Now it's installed )
6. But the launcher keeps force stopping.
So I cleared touchwiz home's data and cache from app manager.
7. Now it's working fine.
I also installed Bixby app through the same process.
Hope this solution works for all those who face the conflicting signature problem.

For some reason i was reset(hard) my phone (by wiping data + cash partition). After successfully reset when device is turned on i found an unexpected error like below:
Device Locked
Device Management has restricted certain features on your device.
Please contact the administrator to re-install Device Management to recover your restriction.
Now I can't access CAMERA(security policy restricted camera), SD-Card not found(showing not inserted), Bluetooth is also disabled. USB-debug is also disabled although DEVELOPER OPTIONS is enabled. Screen-shoot is also disabled. I have flashed my mobile multiple times after that occurrence with proper updated files(AP,BL,CP,CSC,pit). But my problem is still remain. I really don't know what to do. Plz help me out. Thanks in advanced.
N.B: I have also used a fresh gmail account but problem still remain. I have a backup EFS folder but i can't root my phone as usb-debug is disabled. I was tried multiple times to root my phone by CF-Auto root for sm-g930k but it stuck on KT logo and as a result i have flashed it again and again. :crying:
Sorry for my bad english.

I have followed many suggestions, but have failed so far. ONE of many difficulties is that I can not get the phone to download iRoot APKs, so did it on my PC instead, and succeeded in copying them into the Phone's DOWNLOADS (quite visible on my PC) but the phone does NOT show them when I open Downloads - so I can not try to install them to see if they will root the phone. A solution to rooting would be welcome; as also how to make those APKs visible in the phone.
I downloaded and installed File Manager App and that revealed the files copied in. One problem solved. They would not install until I had changed Settings to allow APK's from unknown sources to be installed. Second problem solved. Rooting was solved by installing iRoot. Third problem solved. But even then I could not dispose of unwanted system Apps, till I downloaded and installed NoBloat Free; Fourth problem solved. Then Application Manager offered to uninstall updates, with the warning that the app would be replaced by the factory version, but went ahead and uninstalled the app anyway. Fifth Problem solved. HOWEVER, even though Application Manager now only shows a handful of apps, the screens are still cluttered with many icons I was hoping to be rid off. Can someone tell me how to remove the already uninstalled apps from the screens ?
