Google Wallet can't setup cards

Hi
I have the GNote 3 and installed the Gwallet...because i like using it with my nexus 4 before....But now when i open the App in my Tmobile GNote3 , I can't set-up any cards or the option of adding a card is omitted . Can some one help .?

OK, here's some technical info.
The Play Store installs two different versions of the Wallet 2.0 app, depending on whether you present yourself as an NFC-pay supported phone (via build.prop values) or not.
If you change your build.prop to be, say, the Sprint Note 2 (SPH-L900 t0ltespr) and then install Wallet from the Play Store, you will get the NFC-pay enabled version. All other phones get the "castrated" version.
Now, on Note 3, even if you do that, there a few things Sucksung/T-Mobile did in the stock ROM (completely reversible) to make NFC-pay on Wallet not work.
First, they removed the Wallet signature keys from /etc/nfcee_access.xml, so Wallet will complain it doesn't have sufficient privileges to the secure element. That's fine - you just add the keys back (get them from any AOSP ROM), and boom, Wallet has access to the secure element again.
Then, there are a few other bits and pieces of system software (libraries and kernel modules) that I'm trying to figure out that need to be in place for Wallet to work, as right now it just FCs. If not me, then someone will probably beat me to putting together a "fix" ZIP package that will re-enable Wallet on the stock ROM.
This problem, of course, will not be present on any AOSP ROM as all the required bits are included in those by default.
Also, remember Wallet 2.0 no longer includes a root, region, or carrier check, so "Wallet Patcher" plugins for XPosed or anything like that are not required.
The way to set up NFC-pay enabled Wallet 2.0 on an unsupported device (with a ROM that hasn't been carrier-castrated to disable NFC-pay):
1. Change your build.prop to masquerade as a supported device (e.g., SPH-L900 t0ltespr) and reboot.
2. Go to Play Store, install Wallet.
3. Launch Wallet and set it up as usual. Once it finishes and you see "Ready to Tap and Pay" undearneath your Wallet balance, you're good.
4. Restore your build.prop to its original values and reboot. Wallet NFC-pay will remain working.

Persistent Adware despite TWRP wipe of all data

I got a nasty bit of adware from the internet--clicked a banner by mistake. Now I get popups telling me my SIM card is 58% infected, etc, and it wants to redirect me to download some app to remove it, etc. I never downloaded their app, but the persistent popups need to go.
I've tried running ~5 anti-virus/anti adware apps, none of which can even identify a suspicious program. I've done factory resets, which seem to fix the issue for 2 weeks, but then the popups recur. I figured it was either somewhere deep in my phone that didn't get erased with a factory reset, or it was being synced to my phone from my linked google account (I use project FI, and have to have a google account linked to the phone to have service).
So most recently, I installed TWRP, and wiped everything (cache, dalvik, data, system...completely removed the OS). While the phone was in that state, I used my laptop and cleared all my google sync data, removed all stored google data, and reset all settings to default. I then reinstalled stock Bullhead Oreo 8.1 over a USB. However, it again worked fine for 2 weeks before popups returned.
Is there some deep recess in my phone that I am not effectively deleting? Could it be syncing over my google account somehow (I don't have this problem on any other device with my google account on it)? Could it actually be my SIM card that infected?
I appreciate your help!

It's possible for a Sim card to get malware, but I haven't heard of anything specific. Are you restoring apps from Google? And if so, are there any sketchy apps you're restoring? Those are the only two areas I can think of where malware could be coming from. A complete os restore with the factory image should remove any malware. I'd get a new SIM card from your carrier, then restore the firmware. Use the flash-all batch file in the factory image.
Sent from my [device_name] using XDA-Developers Legacy app

Thanks for the reply. I don't restore apps as best as I can tell. When I reset the phone I select the option that says "start from scratch" or something like that, and at every choice during setup I choose to not import anything. I do have to link the phone to my google account for my Project Fi service, which does sync my contacts, so possibly something something gets transferred that way? Like I mentioned above, I've scrubbed my google data every way I could find.
I don't have any risky apps, just standard ones from the play store (outlook, pandora, etc). No risky online websurfing, just the one banner I clicked some months ago. I even rooted my phone not too long ago and used the ES File Explorer to try and find suspicious looking files, but didn't find anything. Phone is no longer rooted since flashing factory image recently.
My phone even had the bootlooper issue common to Nexus 5Xs, and I sent it to LG for free repair. They replaced some hardware (not exactly sure what), but still had the popup problem occur 2 weeks later. Bootlooping was fixed though.
I talked to Project Fi about a SIM card. They weren't keen on sending me a new one, but I'll try them again.

Recovery Mode via Pixel

My brother died unexpectedly two weeks ago and I am trying to access data on his Google Pixel 2 XL. At this time, I have access to the google account that he used with the phone but I changed the password so "Find My Device" via Google cannot locate his device. I've verified that the phone was backed up at some point on the day he died, but am unsure of the time and am unsure of exactly what was backed up. I've done lots of research online and I've come to the conclusion that the only way to access the phone now is to enter recovery mode via the phone and wipe the phone and restore from the back up. I've found conflicting information about what the downside is to this approach. First, I know that I can only restore what was backed up. I'm okay with that. But I saw somewhere that the passcode for the phone is still necessary if you want to go this route. Is this true? I do not have the passcode and do not want to get stuck in the middle of trying to restore the phone. Second, will this approach erase all logins and passwords for all the apps that he currently had on the phone? What problems could this approach create as I try to further piece together his digital accounts/ information? Would it be possible to find out what his passcode was? This would help with all the other devices he has.
Finally, is there any way to look at the backup stored on the google drive without wiping and recovering the data to the actual phone? I do not want to do anything illegal; I'm just trying to piece together his last days. I'm the legal next of kin.
Thanks in advance for your help.

Someone else made a very similar post the other day....
The best thing to do do is this: https://support.google.com/accounts/troubleshooter/6357590
This is the only legal way to try and access someones account after death, and even then it my be limited:
In certain circumstances we may provide content from a deceased user's account. In all of these cases, our primary responsibility is to keep people's information secure, safe, and private. We cannot provide passwords or other login details. Any decision to satisfy a request about a deceased user will be made only after a careful review.
If Google themselves cannot provide password and logins, or data, then sorry, but no one here is able or going to help you break google security.
Knowing the passcode of one device wont help you with others, they can be different
Not knowing what youre hoping to recover, no one can tell you whether it accessible via google services
Depending on the phone there may be a lock that survives recovery wiping and is linked to the account, because its designed for preventing exactly what youre trying to do, and beat security.
Security is there for a reason, and not trivial.
So i refer you again to the google link above....
And a good reminder to not forget to enable inactive account manager, to avoid all this yourself: https://support.google.com/accounts/answer/3036546?hl=en

When setting up a device after a factory reset Android will ask for the email address and password of the last account used. Based upon your post, you have that information so you will be able to continue. If I recall correctly it won't ask for the pin as that is a local security feature and not backed up. His contacts and text messages should be restored after the factory reset. Usernames and passwords for non-Google apps may be restored, if I recall correctly, but keys for 2FA apps will not be restored. If your brother used 2FA you won't be able to access the accounts using 2FA unless he had backup codes stored somewhere on his PC.
Unfortunately, there is no way to look at the backup, as Google doesn't make the backup visible to the user in Google Drive.

Thank you.

Thank you! I have the information I need. I was just concerned that I would need a passcode and then I would get stuck. Otherwise, I located the backup on the google drive and can see that it was actually backed up on the day he died, so there should be very little data loss. Thanks so much.

If you can't access it using a PC you're boned.
You have the ability to use an SD card as a data drive, why didn't you?
All your critical data should be stored there for reloads and... this.

So the hardware's still good?
Check alternative 2nd email account if you have one to determine if it was unauthorized access took place.
Factory reload and change Google password after reload.
*You may have to reset Google account password if it was indeed hacked before you can regain device access. Try the original password first.
You get 3 tries before you get locked out for 72 hours.
If you got hacked, one or more of your devices was/is compromised. Always use a strong password and change it every few months.
Never use a "master" password for the Google account, it needs to be unique.
ALWAYS backup critical data on the PC and at least 2 more hdds that are physically and electronically isolated from the PC. If the your PC got hacked don't connect the backup hdds until it's clean.
I keep the laptop I use for backup offline and with no Google account on it for this very reason...

Question Play Store: unable to log in to account

Hello everyone.
I can't install or update any apps because Play Store doesn't see any Google account - it says I need to log in but I am already in.
I think I know what happened. My friend wanted to delete some apps (docomo, Google) which he doesn't need and after factory reset docomo apps were installed but some Google weren't.
So, could you tell me which apps are installed (with APK names if possible) on the device at start?

If your friend just deleted those apps from within your devices settings app, a factory reset will restore those apps again.
System apps are only permanently lost if they are removed with high privileges (having root access).
Can't you log in manually in play store or remove your current account from the phone and then reconnect it?
Also, did it help to delete the data of play store as well as cache?
