Google wallet fix for SGS3 US variants AT&T, T-MOBILE, US Cellular, VERIZON, etc

Understanding google wallet

the new google wallet is now available on ALL devices, however the "tap and pay" feature isn't
the tap and pay feature is officially only supported on the following devices

other phone can support tap and pay.... they just need a work around

for google wallet (TAP) to work first your nfc libs need to be correct (smx enabled)
and second the google servers need to see that your phone is supported for the initial setup (build.prop edit)

for example, if you have an AT&T galaxy s3, the smx (most likely) is not enabled because they want you to use ISIS (which uses the secure element in the sim card)
We cannot compile the att version of touchwiz because we have no source, we can take the correct libs from a sprint gs3 to use on an att phone (see lib fix below)

When trying to get wallet to work on a new device/rom take the following steps
1-instal wallet from play or side load. Set up and see if tap and pay is enabled. if no, see step 2
2-change build.prop to galaxy nexus (see below) uninstall wallet then reboot and repeat step 1. if no, see step 3
3-run a logcat while opening wallet and look for "wallet" , "nfc" , and "smx" . Most likely at this point you need a (lib fix) In other words, you need the smx enabled libraries and corresponding files from a supported device. flash appropriate files (see lib fix zip) and start at 1
4-once google wallet TAP is working, the build.prop can be reverted, but sometimes is will break wallet (TAP) and it might take a couple times for success. keeping the build.prop as galaxy nexus has no real side effects (I currently have a sony galaxy nexus )

old wallet fix
*The lib&nfc fix is intended touchwiz roms
For CM9/10,aokp, and any other aosp rom, just flash the desired version wallet as the libs and nfc apk are correct

Google wallet (rom) compatibly list
to contribute here is the google wallet compatibly list thread

Ok, first a little background

basically what you are seeing if you try to install google wallet on at&t, tmo, etc, is you get stuck on "activating device"
If you dig a little further and ran a logcat, you will see that there it no "SMX detected"

What this means, when compiling the rom you need to enable SmartMX in the config headers located in the external/libnfc-nxp library. (thats why it works on CM9/10, they do this)
this is impossible for us because there is no source for samsung's TouchWiz. We got a break on the international sgs3 as the latest update has the secure element enabled...so does the sprint sgs3

well that got me thinking, and of course sprint's nfc libs are close enough to work without breaking anything

so this is how to do it. (btw, you need root)
1-make a nandroid! I am not responsible if you mess up your device
2-edit you build.prop using root explorer (when you press save, it creates a build.prop.bak)
do not use ES explorer, it does not save correctly, for that matter ONLY use root explorer! (or adb push/pull)
/system/build.prop
preferred
or

3-If you already have Wallet installed...open wallet, go to settings and "reset google wallet" (if it hangs at 99%, reboot and continue with steps)
(if you are (re)installing a new rom, this applies too...reset google wallet from within app)
4-boot to recovery and flash SGS3-TW-US_variants-lib&nfc-fix.zip for ics touchwiz roms or SGS3-TW-US_variants-lib_nfc-fix-jellybean_4.1-1.zip for jellybean touchwiz roms and then wallet version com.google.android.apps.walletnfcrel.modaco.1.5-r87-v15.zip
(for CM9/10, I9300, aokp, aosp roms just flash the wallet zip)
5-reboot device, you will get "android is updating" (only this first boot)(all apps)
6-open google wallet and sign in. add your personal credit cards (you must add them from your desktop first if you have never used google checkout before)
7-(optional)if you get "error adding card try again later", wipe cache and davlik cache from recovery (only once! it sometimes takes hours, not minutes)
8-profit (hold on! your not done, continue on to steps 9 & 10)
9-after it is all up and running (meaning cards added), mount r/w in root explorer, delete the modded build.prop, then rename build.prop.bak to build.prop
10-make a new nandroid with working wallet and put it in a safe place in case you ever accidentally install a new ROM without resetting google wallet data.

still confused, here is a video of how to do it by moonfire711

>Special thanks to Hammermann, he did a ton of nandroids! He confirmed for me that the sprint nfc libs worked
>Special thanks to WarlockLord we now have success on verizon
>thanks to mobilehavoc for the galaxy nexus build.prop tip
>thanks to magn2o for patching the new wallet (until paul returned)
>thanks to FreydNot for for the above tip and for being brave enough to be the first to flash this to his tmobile sgs3
>thanks to chris.ayoubtexas, the first att user with success (beat out Hammerman because ES explorer was screwing him)
>thanks to Maldewka for installing and confirming functionality on US Cellular
>thanks to Paul at Modoco for the modded google wallet apk<<<Paul's thread

notes*
-if you have used google wallet on another device, your prepaid card on the sgs3 is not the same...so balances will not carry over on the prepaid card prepaid is finished
-despite the new cloud-based authentication system, the app does not require the phone to have a data connection to make payments at NFC-equipped terminals
-really the key to this fix is the libs with the security element enabled.
-the build.prop edit is for enabling cards, once they are enabled it can be reverted
-the wallet apk has 3 features patched out. The first was a device check, the second patch was an operator check and the third patch was removing the root warning
-NEVER, I REPEAT NEVER RESTORE GOOGLE WALLET WITH TITANIUM BACKUP! (please click link on step 10)

This is a modified version that does not require editing your build.prop!
It will probably work on any device. The only thing you might have issues with is the nfc.

Try the following:

1. Force Stop on Wallet app
2. Clear Cache and Clear Data on Wallet app (in Application manager)
3. Delete all traces of it from both locations /system/app and /data/app/ (might be called Wallet.apk too)
4. Reboot
5. [OPTIONAL] Flash a fresh version of your AOSP-based ROM (no wipe required)***
6. Push the apk from this link and set the permissions (DO NOT OPEN IT YET!!)
7. Reboot
8. Open the Wallet app and set everything up
9. Check what Tap and Pay says in "About" section of the app
10. Confirm what happens on transaction

***Note*** If the ROM your are flashing is TouchWiz-based for step 5 you need to flash one of the below for your device BEFORE step 6 and then continue.

Details/How you can do it to:


NOTE: Please share this as much as you'd like, but please give me credit. I've spent far too many hours on this.
ANOTHER NOTE: If you get "Insufficient Privileges - blah blah (release-keys)" then you need to find an nfc fix for your device.

EDIT: I updated the apk and used a maguro (Galaxy Nexus) build.prop and changed every reference to build.prop, except sdk/version numbers. I personally tested a transaction and it went through successfully.

I went ahead and patched the latest wallet version and removed the root check, carrier check and device check. This isn't my work. I simply diff'd modaco version and applied the same mods to the latest version.

It's working fine on my device (SGH-I747).

Download!

* edit: APK has been repacked with compression.

Changed the lines, forced stop, cleared the data, deleted the com.google.android.apps.wallet folder in /data/data, rebooted and it went through. I am not sure that all the other steps were necessary but I did so just in case there was a trigger stored in a data file somewhere.

Ok, so there is hope! I'm building a new one right now. I changed everything to the maguro build.prop and I modified ALL instances of model, product, device, id, etc. inlcuding in About and User Feedback.

EDIT: Here's the new apk for anybody to try. I can't test transactions at the moment. You can just overwrite the system app, but I would suggest clearing data for wallet and then overwriting.

I might have this working on 4.3. Tap and pay is setup and ready to use, but it's 2am and I'm not going to 7-11 to test right now. I'll make my wife walk with me tomorrow morning. If everything goes well, I'll upload.

If you've used @dannyben's fix you'll know about the nfc payment has stopped (at least that's what I think it was) error message. That's because he used AOSP based files, whereas mine is modified TW files so no popups.
