Awesome!

########## IMPORTANT UPDATE ##########

There is an APP available that makes this much simpler

* No Console Commands Needed

* You still MUST HAVE ROOT

* It must be installed on internal memory to work correctly

* Be sure you know what a system app does before you remove it.

* If you remove a vital app you could mess up your system completely.

The APP is Called: "System APP Remover"

Here are the console commands for installing/removing system apps in android console emulator, very easy ; )

You must have ROOT and console emulator, I found this very helpful, so I hope it helps others as well...
_____________________________________________________________________________________
Install App to System:

Place APK file in the root folder on your sd card.

Open terminal and enter these commands:

# su
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
# cat /sdcard/filename.apk > /system/app/filename.apk
# mount -o remount,ro -t yaffs2 /dev/block/mtdblock3 /system
# reboot
_____________________________________________________________________________________
Remove App from System (Be careful what you remove):

# mount -o remount,rw /system
# rm /system/app/Filename.apk

[Optional, to make read-only again]
# mount -o remount,r /system

[When Finished]
# reboot

_____________________________________________________________________________________
****KEY****
"#" means root command will follow
[Notes are in these brackets and aren't commands]

- ENJOY

ALSO...

**** I'm new to Android APP creation, but if anyone can automate this script to make a simple One-Click GUI APP that would be awesome, all I ask is that you put my name in the co-dev/"Thanks to" list for the app, just so I can say I helped ;) ****

Thanks for that, really helpful, also there is this very neat app that can do almost everything app related given you are rooted (ROM Toolbox Pro)

anyone can check it out, although I'm sure most of you already know it (well worth buying the Pro version)

All the best!

You can, but many proprietary apps from OEMS require a lot of framework, often a big job

than, it mean I can't just push the app to system/app??
one thing that I love in my srock JB is the clipboard option in message app.. something that I didn't meet on message app of cust ROM 4.2.2..

You can try, just push it and set permissions. If it doesn't work than it may just need libs, check the stock ROM for any libs that are associated and push those to (fix permissions) if it still won't work then you would have a lot of extra work and probably not worth it
Oh, may be nice to make a backup first just in case, but you probably won't have any issues other than some fcs

Then become one yourself :)
But for future reference, if your phone has its own forum on xda there should be many helpful people there that know the specifics of your device
Happy flashing!

Hey guys, I tried to follow the instructions to install the Background Defocusing app on my rooted Xperia Z1 Compact (http://www.xperiaguide.com/2014/01/...ocus-camera-app-apk-install-rooted-xperia-z1/) but nothing seemed to happen. After pressing enter following each command, it felt like nothing happened. And then after rebooting, I couldn't find the app (which should be inside the default camera app). Can someone give me a hand?

Try re-flashing your rom. Make sure you have back-up.

Hi,

I have made an app that can uninstall system apps in a similar way, but just like your method, it requires restarting the OS.
I've noticed some apps that can do it without restarting. How do they work?

I used terminal emulator and did exactly what it was said here. Then i reset my phone from the settings to see if it really has worked but now my phone keeps rebooting after showing the logo and then going to the factory resetting logo. I cant acess the recovery mode too. Please help.

I tried a lot of system removal apps like Root system app uninstaller and all , nothing worked. Tried piriform's ccleaner with root permission, didn't worked for me. But finally found a maid that can do the job. YES , SD MAID FREE OR PRO , YOU CAN USE ANYONE OF THEM ...WORKS..GIVE IT ROOT PERMISSIONS AND IT UNINSTALLED MOTO CAMERA THAT I FLASHED IN SYSTEM WITH TWRP.

SO THERE U GO...SD MAID IS THE ANSWER;)

    It will work. Check the following:

    * All shell commands are CASE-sensitive, so if the app is called Vending.apk you can't type vending.apk

    * for the command to work you must have the apk on the root of your SDcard, not in sub-directories.

    * if you have a copy of the rom you installed you can unzip it on your PC and find the system app folder, which you can use to cross-refference with the system/app folder on your phone to see if your missing something else.

    in terminal you can list system apps like this:

    # su
    # cd /system/app/
    # ls | more

    [that will allow you hit space bar to navigate through app list if it's longer than a page,press ESC when done to go back to prompt]

    * If all else fails you can backup your settings to your sd card and re-install your rom (as a last resort)

    -Good Luck

    yaffs is nand flash filesystem
    yaffs2 is more elaborate updated version
    yaff2 has greater support
    so if your device isnt supported by yaffs1, it may not work.
    it's best to follow the commands as they're written.

    apps still appear as apks in system/apps folder after installation.
