[Q] NFC Question - Samsung Galaxy Nexus

So I saw on DL today that if you wipe your phone, your NFC stops working? Did I read that correctly? I just got my (VZW) nexus yesterday and as soon as I got home I rooted and wiped and ROMed it. I didn't install Google wallet prior to wiping and I still haven't installed it. Did I screw up my NFC?
Thanks

I read that today too after already rooting and throwing on a rom. I had been meaning to set up wallet but hadn't yet. So when I saw that I figured I'd give it a shot and see if it works. It did and I got my free $10 credit.

I wonder this too. It would seem to me that if you never setup wallet in the first place, there's no reason the secure element could be disabled (for lack of a better phrase). But since I have had this phone long, I'm not sure.
But I did root -> wipe -> install AOKP and wallet didn't complain, but after flashing a new kernel, I got an unsupported device warning.

The unsupported device warning shows if you're rooted.

The suggested practice for doing a wipe is to go to the Wallet App- Settings- reset Wallet. Then do your wipe or flash as usual.
Haven't tested it either way. Just passing along useful info.

If you have setup google wallet and then wipe and flash a new rom there is the possibility of killing your secure element. It is suggested to reset wallet within the wallet app before wiping and flashing a new rom.
There is a huge thread in the galaxy apps forum that is usually within the first few pages.

A simple wipe will not affect NFC.

Wiping does not ruin your NFC. What these articles were talking about is wiping and flashing a new ROM without first de-authorizing your Google Wallet app/account. Its a security measure that once the phone has been wiped w/o first de-activating it won't respond to Google Wallet anymore.
Just de-authorize your Google Wallet app before wiping and switching ROMs and you're fine.
I really wish people would understand the difference between NFC, which is the connection standard and radio in your phone to initiate data transfers... and Google Wallet, which is just an app that uses NFC to make mobile payments.

well i guess the question i'm asking is: if i've NEVER set up google wallet in the past and have previously wiped, will google wallet be affected?

No... theres was no Google Wallet data to wipe and deauthorize in the first place lol.

That's cool, I haven't set up Google wallet yet and wiped about a dozen times already.

From what I can tell you should be fine, I did a factory reset right after I got my Galaxy Nexus never having set up Wallet at the time and from what i can tell nothing went rotten on me i.e. no errors when I launch Google wallet. Haven't tried to make a payment though which I should do soon apparently there's a 2 dollar a month upkeep fee on the Google prepaid card if you don't touch it for a 30 day period running on a tangent now, cheers!

Secure Element Prevention?

Okay, so I've become increasingly paranoid of the SE error that's been plauging various Nexus's over the internet. What I can gather from these is that the phone was either:
1.Not properly wiped between ROMs
2.They tried restoring Google Wallet from a backup
3.They flashed the App from the ZIP/APK (Unofficial)
4.They used a preinstalled version of Google Wallet on the flashed ROM
So, now that we can officially install Google Wallet from the Market, do you think that it should be safe to switch between ROMs? I used Google Wallet on my first GNex and it's been one of the best parts about this phone. I would really not like to lose this functionality on a device I dropped $600 on...
Yeah, thing is when you "reset" wallet to flash a new rom it locks you out of prepaid. Some chuckle-head with creative fear mongering has got the bloggers excited over some security crap. If I lost my device I would be more worried about my device that the Happy Meal they could buy at McDonalds with my prepaid card!

So how do you flash a new ROM without getting locked out of your prepaid card?

Wait, it only locks you out of prepaid? Not the Citibank and total Google Wallet functionality?

yes only prepaid. afaik citibank works fine.
If you get the "secure element is not responding" error you're dine with Google wallet until you get a new phone. I'm in that position and that's what Google and Samsung told me

well i dont know if this has been found out before, but here is my story
i got the hong kong nexus gsm back when it came out here in dallas tx. flashed it to stock google yakju. i used the wallet app apk and everything worked great. when the update came out it stopped working.
go to settings, apps, all. go to wallet, clear data. go to google account manager, clear data. go to google services framework, clear data. once u do that go to about phone check for update. it will have some weird 1969 date. once it checks open wallet and now it works. only thing is pre paid error when adding card
so i flashed to the new takju and same thing. followed thoes steps and same thing.
as far as i can get with wallet

If you are getting an error when adding your prepaid Google card and you previously had one activated, you need to call Money Network and have them do a master reset on your account. The number is 855-896-0693.

Will try thanks
Unsuccessful
I tried, but it did not work for me. I'm still getting the "secure element..." message. Has anyone tried activating with a different battery?
The battery is an antenna. Nothing more. Secure Element lives in your phone.

Does the master reset really work? I tried this from an apk long time ago and now it won't work with the market installed app and won't allow me to add a prepaid card.

I did Wipe Google Wallet from within the app, and after which i went back to google wallet and it's stuck there.
Stays the same after reflashing 4.0.4.

Root + Google Wallet

Many figured out on the HTC EVO 4G LTE forums that Google Wallet and root don't mix as well as me seeing the same "unsupported device" on a new android device. So here is the quick fix until someone can verify someone elses modified Google Wallet apk will work on our device.
Posted by Dark_shadow70 (the method of the quick fix has been found by many)
if you are rooted and you're using google wallet you'll see an unsupported device warning, wallet still works but it's annoying.,
here's what I did.
Make sure you wallet is not been setup, if it has, reset it to factory.
before you start wallet,disable super user (I'm running super SU v0.93)
(open super SU,settings, UNCHECK enable super SU)
setup wallet until you see your balance and the wallet is activated.
exit wallet.
enable super SU
open wallet, set it up and that's all, it worked for me, I hope it works for you..!

The other question is can anyone confirm their NFC chips on their tablet is fine after flashing a rom? On the Evo's side, their chips were ruined if they didn't clear the settings before flashing a new rom.

You should always reset wallet from within wallet before flashing new rom's. The same thing happens on the Galaxy Nexus - secure element errors.
Wallet works fine with root. The only difference is the notification at the top, but it still functions the same.
You're saying to not flash a rom until you clear wallet data?

Don't flash a rom or update on if you use Google wallet without going into the wallet app and using the built in clear settings (If you wipe app data you will not be able to use wallet any more)

wallet works fine with root, you just don't get any support if you have issues.
Google Wallet no longer shows up in play after rooting jr003d.

Unlink Google Wallet

i'm not sure if this is the right place to be asking this, but here goes.
so i had a modified version of Google Wallet installed on my rooted Galaxy Nexus. well, i then started to prep the phone to be sold, so i wiped the phone, and flashed a ROM. not realizing until after that i guess there's some weird authentication things with Google Wallet? or something?
well anyways, i didn't make a nandroid backup because my primary device is my (non-rooted) Galaxy S3.and so my Galaxy Nexus was more like a music and games player with a working Google Wallet.
i haven't tried this yet, but would i be able to install Google Wallet again on the phone, then unlink/reset it, and then wipe the phone?

google wallet is unique to the device b/c of the 'secure element'. If you didn't break the secure element, then a re-install of wallet should be fine.
You may have just encountered the secure element error where you didn't restore Google Wallet completely before you wiped your device. If that really is the case, you won't be able to use Google Wallet on it ever again unless somebody devises a fix for it.
I tried to install Google wallet to the phone on the same ROM and different ROMS.
I'm getting the your device isn't supported error now. I've tried 2 different APK files, and I can't download it from Play store.
Any suggestions?

Device isn't supported just means that you are rooted - doesn't effect functionality...
Correct unsupported device is normal, that means your phone is rooted and money market is not responsible for any loss of money because they feel that a rooted device is less secure. The secure element issue is when your device is broken and the wallet will never work again. At this point your perfectly fine and just like everyone else. If you flash stock and lock the bootloader your unsupported device message should go away.

the only thing that weirds me out though, is that i had Google Wallet working on it while rooted, but now it's not working.
before, when it was working, that dialog would come up, but then still let me use the app. now it's just auto closing after the alert dialog.
guess i shouldn't worry about it too much since i'm trying to sell it.
Please see wallet.google.com
You can remove all devices, and as soon as the device opens the Google Wallet app, it blows itself up!

Wallet issue

So I'm having trouble getting Wallet setup on my Galaxy Nexus...works fine on my Nexus 7.
I can setup the app, but when it says 'setup required' under the card, it always fails to add card. See attached photo.
I've tried resetting the wallet app. I've restored to stock, flashed factory images. I'm unrooted. Can seem to get this fixed. Any advice?

I have the GSM version...
So I called Google Wallet. They told me that the UNLOCKED GSM Galaxy Nexus is NOT SUPPORTED to run on Google Wallet! The new app makes this so. ONLY the Sprint version of the phone is supported! This can't be right can it? Two guys in Google Wallet support said this, including the manager. Any advice? Is this really true?
I'm running it just fine on the unlocked gsm with at&t, don't know what to tell you

GSM should be supported despite what they said.
Beamed from Maguro
I use it on unlocked GSM on T-Mobile.
Right! I know. So I'm getting this error I posted about whenever I try to setup. Makes NO sense whatsoever. I've reset my phone like 10 times and doesn't work. Tried adding different cards, etc. Tried to setup without my sim card inserted even! Still no go.
just set mine up. GSM unlocked phone from google. Unsupported Device Policy message on top of screen during set up. Set up went ok, it picked up my card number automatically. "Learn more" next to unsupported device msg linked to message:
"Some users may disable important security mechanisms in order to gain system-level "root" access to their device. We strongly discourage doing so if you plan to use Google Wallet. We are unable to support devices with unatuhorized operating systems as the security layers of the device may be limited."
After setup it starts and appears to be functioning, but nothing to try it on. Still has the unsupported device msg also.
Unlocked and rooted my phone, running stock 4.1.
So some of you have actually made purchases with wallet? I have tried at different stores like Best Buy and Home Depot and it connects, but won't let me make my purchase. I have that $50 from buying the phone I need to spend, but can't get it to work anywhere. Anyone have any suggestions?
Me too, on Sprint rooted phone

I just got off the phone with Wallet specialist. He said Wallet would not work on my Galaxy Nexus that I unlocked and rooted. I am running the stock Jelly Bean, but alas, no Wallet. I might as well uninstall it. Bummer.

I think the Wallet guys have no clue what they are doing, support-wise. It's a massive fail imo
Just installed Wallet on my unlocked, rooted Galaxy Nexus. Everything went fine. Credit card added with no problem. Says I'm all set up, but haven't used it yet. I get the "Unsupported device" message but I'll believe that if and when it fails. Note that if you have certain parts of Google apps frozen, uninstalled, or blocked with a firewall, Wallet won't install. PS: Take anything a sales rep says with a grain of salt.
