How to install Google Wallet on the T-Mobile Galaxy S III running TouchWiz Jelly Bean

One thing that deterred many folks from trying out the leaked TouchWiz Jelly Bean builds for the T-Mobile Samsung Galaxy S III was the lack of support for Google Wallet. While no official builds for the phone include support because T-Mobile still isn’t on board with the service, there was at least a workaround for devices running Ice Cream Sandwich.

Thanks to XDA Senior Member joemagistro, those of us running Frosty JB, LiquidSmooth, or any other TouchWiz-based Android 4.1 ROM can now join in on the action, too. All credits go to Joe here, who dug through Sprint’s latest leak and compiled a flashable zip file to make the app work on our phones.

This may or may not work with other carriers — I can only vouch for the Magenta Galaxy S III, and I can say the install was pretty simple, as long as you don’t mind editing your buildprop file. If you don’t feel comfortable using a text editor to edit the file, there’s a handy app available for free on the Google Play Store, called BuildProp Editor, that makes it a simple task.

Here’s what you’ll need to do:

Open your buildprop in text editor and edit these fields:

• ro.product.model  to Galaxy Nexus
• ro.product.name to yakju
• ro.product.device to maguro

Save your buildprop file, then reboot into recovery and flash the JMJellyBeanWalletFix.zip (head to the source link to download the file. Reboot your phone again.

Now, head over to the Play Store and download Google Wallet, install it, and you’re good to go. You’ll see an “unsupported device” warning at the top of your screen, but you can disregard it — it’s only because you’re running a rooted device.

Thanks again, Joe! Now it’s time for me to hunt down some places here in Des Moines that will let me pay for my tab with my Galaxy S III!
