Device with TWRP installed -> twrp-3.0.2-0 twrp-3.1.1-0 twrp-3.1.1-0 If you need explanations how to do this:

- 4- Download and install Odin3_v3.12.3
- 5- Download and install SAMSUNG_USB_Driver_for_Mobile_Phones_v18.104.22.168 (Sept 2016)
- Follow steps from 6 to 10 at How to installing TWRP
- You are now in TWRP recovery, follow next steps below.
- If your internal storage is encrypted, format it > [Wipe]/[FormatData], type "yes". (if you're just installed TWRP it will be encrypted).
- If your internal storage is not encrypted normally it will not be erased but make a backup for security.
- In TWRP, [Wipe]/[AdvancedWipe] check "System", "Data", "Cache", "Dalvik/Art cache" (Don't check Micro SDCard !!).
- In the home screen of TWRP, tap on [Install], [Select Storage] where Extremely Rom is stocked, select "Exmely_vx.x.xb85x.zip" then [Swipe to confirm Flash] and wait until ending.
- Reboot to System, don't be afraid, with SuperSu you get 2 time boot.
- Be patient, deodexed rom take long time for the first start 2-4 min (and every time you wipe Dalvik/Art cache).
(If you do not know what it is, or you want to keep all the functionality, just skip this step)
After the configuration of your Android system, you can use "DisabledPackage.xml" in your SDCard, to import in Package Disabler 1.x.x app, this is the list of packages that will be frozen. There is lot of apps that not essentials for me but may be usefull for others, you can defrost at any time to get they functionality working again.
Important note, when you import the XML file, the app start directly to freeze the packages and your device seem blocked, just wait 1-2 min and the process will end.
I have deliberately not permanently removed the "packages" of this list to allow some people to have features that are currently not useful to me, such as: "NearbyServices, QuickConnect, PrintServices, ScreenMirroring, Smartview, GameOptimization, etc . . .", I preferred this way so as to be able to activate these according to the future needs. At first boot, none of these packages are frozen, it is necessary to use the soft included in the rom as indicated above.
Some reminders: A frozen application does not appear in the system, is not available in the application list of the phone, consumes no resources and can not be launched by the system.
