Carrier Aggregation Toggler

Today I am releasing a utility that will enable or disable LTE Carrier Aggregation (CA) on the SM-G900T. This is intended for users on the rooted stock rom only. T-Mobile does not currently use carrier aggregation. Therefore, this is for users who have unlocked phones and are on other carriers such as AT&T. Use this software at your own risk on devices other than the G900T!

What is Carrier Aggregation?
Carrier aggregation is the first step in LTE Advanced commercialization, offering increased user data rates for all users in the cell. The higher data rates can also be traded off to offer increased capacity for bursty applications such as web browsing.

To install:
Code:
$ adb push ToggleCA.apk /sdcard/
$ adb shell
$ su
# mount -o rw,remount /system
# cp /sdcard/ToggleCA.apk /system/priv-app/
# chmod 644 /system/priv-app/ToggleCA.apk

Then restart your device and launch the CA app.
To validate if CA is on or off:
Code:
1. Ensure the device is on LTE
2. Dial *#197328640#
3. Select AS
4. Will either say CA is disabled or enabled
OR, don't use my tool at all!

Code:
$ su
# am broadcast -a android.provider.Telephony.SECRET_CODE -d android_secret_code://27663368378
Then go to...
Code:
[2] UE SETTING & INFO
[1] SETTING
[1] PROTOCOL
[1] AS
[2] RELEASE VERSION
[3] LTE 3GPP REL/CA CONTROL
[2] LTE 3GPP REL 10

REBOOT!
Let's get some people from Chicago to test this!

Does anyone know if this will be compatible with the Project Infinity ROM? I'm planning on moving over to AT&T soon.

Should work on that ROM, but I haven't tested it.

Cool. How do we know that T-Mobile doesn't support it, and how would we find out if they turned it on? Basically, I'm wondering if this will be useful for TMO users in the future.

AT&T is using it as they have access to a scattered group of lte frequencies and they wanted to cobble them all together. T-Mobile is not so lucky or cash rich so they have a much more limited frequencies and are planning a 4x2 mimo approach of doubling the amount of antennas on the network cells to give customers a better signal and less hand off to non lte

Can someone post some speedtest results with and without this? I would like to see what it does before I dig in.

I believe Chicago is the only market to have launched CA on at&t but others should be coming shortly. Now the phone is enabled, it will be able to pick up the RRC messages when it is lit up.

Anyone from Chicago that can test this?

Won't need any configuring on your end. Most major markets will be active this summer sometime but I don't know when.
