[Xperia Z2 Tablet General] SANGER_A2:
I used to use freezing in titanium backup to try and cut down some of the Sony bloatware. The advantage is that it is kept when flashing new FTF images, the disadvantage is that the apps still run and FC! I've made up a zip file to delete the system apps from the tablet that annoy me that can be flashed from within recovery. I have an SGP512 running the UK customisation. SGP511 devices will be the same, but SGP521 devices may not be and phone/mobile data stuff will be removed.

I've taken out nearly all of the Sony unnecessary bloatware except for those needed for USB, MHL, NFC, PS3 Controller connection, home (even though I use novalauncher), basic music playback with the walkman app (go into settings and disable music unlimited), basic video playback, keyboard (even though I use Swiftkey), Screen mirroring, themes, smallapps, I also got rid of the unnecessary google/android apps that can be installed via the play store and just kept youtube, keep and maps. I also deleted the retail demo video and several of the apps in the customisation folders. I moved the smallbrowser app into system as well as the diagnostic apps as they were stored in a random place and not actually installed on my device.

The complete list of items I have removed is here:-

I've tested it on mine and it runs fine, but before you do it for the first time I would advise making up backup in recovery and/or use titanium backup to backup the system apps. I used this excellent software as well as titanium backup to see what apps were installed and what files/packages they related to. If this breaks your device I will help you here, but I take no responsibility for your mistakes. Flashing the FTF image over the top of it will reverse anything this script does without touching your data/settings etc anyway. You obviously need root and a custom recovery installed. Ask questions about that in the appropriate threads here and here. All you really need to do is enable USB debugging, and run the easyroot tool twice, then the lockedrecovery installer.

Any issues, or suggestions of apps to remove please let me know. It took me a while to build up the list and get the script working properly (damn semi-colons).
