[Verizon Samsung Galaxy S III] alphamik3:
**I am not responsible for any damage you do to your phone. This as any other mod is done at your own risk. This is just a guidline on how to get a real fix for blocking mode on your VZW Jelly Bean device.**

This blocking mode fix has been confirmed on both the VZW Note 2 and the VZW Galaxy S3

*You need to be rooted.*

IF YOUR ON A NON-VZW BASED ROM:

JUST FOLLOW PART 3!! (and part 4 if you like!)

IF YOUR ON A VZW BASED ROM:

Part 1

There are two apks that are the reason for blocking mode not working. The two files are the secContacts.apk and the secPhone.apk. You will need download these two apks from a other carriers rom and replace them in the system/app folder in root explorer (or your choice system file explorer) and change the permissions.. (For example download a flashable "att" note 2 rom and copy the secContacts.apk and the secPhone.apk and paste them into your system/app folder. Restart then change the permissions then restart again. Same thing with the Galaxy s3 only you have to download files from another carrier galaxy s3 Rom. From this point on blocking mode will work 100 percent.

Part 2

Now that you have blocking mode working, how can you access it. You can get a shortcut maker app and have a blocking mode home screen icon... OR..You can have it in the settings menu like it's supposed to be! Now just like before there is an apk that VZW had changed to block this. It is the secSettings.apk. So from the same rom you downloaded from before copy the sec.Settings.apk from the other carrier Rom and paste it in your system/app folder in root explorer. At this point you may or may not get a chance to restart your phone (it might freeze for a sec and restart by itself. Once phone restarts change the permissions and restart again. **NOTE: Some roms settings mave have more or less options then the stock. To access these just also copy and paste the secSettingsProvider.apk and everything will work perfectly** **NOTE: menu appearance will not change yet!**

Part 3

Last step. Now that you have the new menu there are still two more files that are causing the menu to change. In root explorer navigate to /efs/imei and delete the map_code.dat and then go to /system/Csc and delete the sales_code.dat. Now restart your phone and you are good to go. **NOTE: after deleting these files any VZW apps on your phone or in market will not be recognized on your phone. For example if you try to download a VZW app from the market it will say your device is not recognized. But they have 'market unlocker' apps that can trick the market to see you as any carrier you want. Also VZW Apps like backup assistant might not work properly.

Part 4

This is not really related to blocking mode but I though I might throw it in here as a bonus. If you copy the feature.xml from another carrier (ex is use the ATT one) and paste it in you /system/csc (I'm my opinion) makes your VZW phone better.The stock email app for example will never try to connect to the VZW server again. It will just go straight to the email app. It also seems to make your phone more responsive and work better with certain samsung apps. (Ex: the samsung apps.apk connects better with samsung push service.* Like I said just a little something extra I noticed.*

ENJOY!

EDIT: Those of you having trouble with step 2 with the secSettings.apk, try the file from either of these rom:

EDIT: You may need to wipe first.
