[Galaxy S III Q&A, (US Carriers)] sekigah84:
Google Wallet - Everything you need to know before you flash or root!​

DISCLAIMER: I DO NOT TAKE ANY RESPONSIBILITY FOR ANY DAMAGE THAT OCCURS TO YOUR PHONE. THIS IS A COLLECTION OF INFORMATION I FOUND WHILE ROOTING AND FLASHING ROMS. I ONLY ORGANIZED IT HERE TO MAKE IT EASIER FOR PEOPLE TO FIND.

Don't forget to thank people who made the ROMs, Root Methods, etc. They put in a lot of work and take a lot of time helping people. All it takes is a click of a button. One for me too! It's a lot of work trying to keep everything updated. =P

This will and always will be a work in progress. If you feel something should be added, clarified, or corrected feel free to PM me. I'm not perfect and I can't read everything so any and all help is appreciated. (Yes of course I will credit you. Just no plagiarism!)

What is Google Wallet?

What do I need to know before I start rooting or flashing ROMs?

The main thing you want to know is that Google Wallet is a pain for constant flashers. It may turn you off completely to being a flashaholic. I'll explain:

Once you add a Citi Mastercard or load funds from any CC to the Google Prepaid Card, it is bound to the device ID, not your Google account! This ID changes every time you wipe data, flash ROMs, and Reset Google Wallet. Meaning if you don't get the right information, all the money on your Google Prepaid Card is gone when you Reset Google Wallet.

So what do I need to do?

For Citi Mastercard holders: You will have to call Citi Mastercard to have your card removed. It can take 24-48 hours to remove. You can check on the status after 48 hours by calling Citi directly at (877) 762-2989. You just add it back on after it is reset. It can be annoying and not take it but it will work after a while.

So to remove the card from the Google Wallet app, do the following:

1) Open Google Wallet

2) Enter your pin

3) Tap "Payment cards"

4) Tap your Citi Mastercard.

5) Remove

Google Prepaid Cards: This one is a bit trickier. Your funds will NOT transfer if you flash automatically. Meaning, it is not bound to your Google account. (STUPID I KNOW!) You will need to know a few things.

Your Google Prepaid Card User ID (prior to flashing)

Your Google Prepaid Card User ID (after flashing)

Your Balance on the card.

Your Google account linked to the account (FOR WHAT?!!?!?!?!?! I don't know)

Write down your Google Prepaid Card User ID.

1) Open Google Wallet

2) Enter your pin

3) Tap "Payment cards"

4) Tap "Google Prepaid Card"

5) Wait for your User ID to load and then tap "Show ID" to see your entire ID number. Write this down BEFORE FLASHING OR CLEARING DATA.

If you have both, remove them both with the instructions above before proceeding.

DO NOT CONTINUE WITHOUT READING EVERYTHING ABOVE! YOU CAN POSSIBLY LOSE FUNDS! YOU HAVE BEEN WARNED!

Once you have removed your Citi Mastercard or have all the information needed for your Google Prepaid Card User ID, you need to then reset Google Wallet or you will break your Secure Element on your phone and Google Wallet will never work again.

WARNING: THIS WILL RESET EVERYTHING AND ERASE EVERYTHING ON YOUR DEVICE IN TERMS OF GOOGLE WALLET! IF YOU DON'T HAVE YOUR ID YET THEN DON'T

To Reset Google Wallet do the following:

1) Open Google Wallet

2) Enter your pin

3) Tap your Menu Button

4) Tap Settings

5) Tap "Reset Google Wallet"

Once you do this you are good to go and flash a custom ROM. You can wipe data, cache, dalvik without an issue.... till you have to get your money back.

After you have set up your new ROM, do the following:

Citi Mastercard Holders: You have to call back Citi Mastercard to make sure it has been reset and if it is, you can try to add your Citi Mastercard back to your Google Wallet account like you did before. It may take a few tries. If you have issues adding your card, call Citi's Tech Support, NOT GOOGLE OR MONEY NETWORK!

Google Prepaid Card: First get the Google Prepaid Card User ID on the NEW ROM.

If you are too lazy to scroll up it is:

1) Open Google Wallet

2) Enter your pin

3) Tap "Payment cards"

4) Tap "Google Prepaid Card"

5) Wait for your User ID to load and then tap "Show ID" to see your entire ID number. Write this down BEFORE CALLING MONEY NETWORK TO MAKE YOUR LIFE EASIER.

Once you have this information, you can call Money Network to have them transfer funds. Their number is (855) 896-0693.

Make sure to tell them you switched phones, you go the User ID for both phones and that you Reset Google Wallet on the old phone and cleared data.

What a headache. I don't know if it will stop me from flashing like crazy but I doubt it! GOOD LUCK!
