Hi everyone,
I lost my Nexus 7 on a plane over the weekend - own stupid fault..sucks!
I hadn't installed a tracking or security app on it. I was logged into my google, amazon, and zinio accounts on the device so was worried about access to my accounts. I've since changed my passwords for all my accounts which has given me some reassurance. A few questions:
Is what I've done enough?
Are there any other measures I should take? (can't install cerebrus remotely as I've changed my google password already)
Is there any way of dis-associating the nexus 7 from my google account from my end?
Thanks in advance for your advice.
1:
I am not sure for Amazon and the likes but I know that for the Google account changing the password does the job.
Everything Googleaccount will ask for the password when it's started now, I do think it similar to the other services.
2:
Report it stolen / lost with it's serial number.
3:
Don't think so.

I have a Nexus 10. I wanted to add my corporate email to the device. When I did I was told I had to add a pin number and encrypt the device. I performed both of these actions no problem. I rebooted the device twice during all of this and was able to enter my pin successfully and use the device.
Fast forward to this afternoon. After using the device for awhile I determined that the slowness caused by the encryption was no longer worth having my corporate account on the device.
I go into Settings and delete the corporate account. I tried to go into Security to remove the pin and encryption but both were greyed out. I thought all I had to do was reboot the device and I would be able to disable both.
I rebooted and now I'm stuck at the "Type password to decrypt storage". My pin no longer works on this screen. It keeps giving me a response of "Try again."
Does anyone know what's going on or how I can fix this?
I'm guessing the security is messed up (somehow, don't know how) from removing the corporate account.
But, just for future reference, the only way to remove encryption from an Android device is to factory reset it. It's not as simple as just going into security and removing encryption.

I heard and seen otherwise. I was shown, by someone who has a Nexus 10, that you can remove the encryption as long as you remove the account and removed the device from the OWA site.
Unfortunately, that person is no longer available to me to help.
So basically I'm screwed and all of my information on the device is gone. No one else has any thoughts?
Well, your data is probably lost, but you can easily factory reset it from recovery.

I think you can skip the password via adb. http://forum.xda-developers.com/showthread.php?t=1800799

Unless I misread, or misunderstood it looks like that'll only work for *pattern* unlock not pin.
Edit: Nevermind, it looks like this post in that thread might have your answer:

To the OP, if it's a simple pin, a brute force script or program could make short work of it in minutes (or hours at most; depending on length of password).

You saw a way to remove certificates for your corporate email account, not remove encryption from your device.
There is only one way to remove device encryption, and that is by factory reset, by design. It wouldn't be very secure otherwise.

Sorry, you heard wrong, or you were listening to a fruitcake. By definition you cannot "remove" encryption. It changes the whole file.
Think of it like this. I just scrambled an egg. Then I'm like "oh no! I don't like scrambled eggs! Can someone help me remove the scramble?"
It's not that easy. Sure, there is brute force, if your apps were THAT important it might be worth it to try.
But the short solution: factory reset your data, or give it the pin it wants.

In the future, NEVER use the corporate account system built into iphone / android, this let's your company apply security policies that can wipe your device remotely, and your encryption junk. Use something like Touchdown app which still syncs your contacts, emails, and calendar into your device for any other app to use, but the security policies only get applied to Touchdown. I know this from experience when my former company's IT department "accidentally" wiped everybody's devices messing around in Exchange. "Whoops."
alright guys. Quick question. Has anyone had any of the "secure element" issues on the Nexus 4? I have been looking around and not found anything related to the N4 talking about the secure element. Lots of stuff on the old G-Nex and Nexus S forums though.
To be clear, I am NOT having the error message about secure element come up on the screen. However, after my most recent flash every time I try to use wallet, the paypass terminal says "unable to authorize payment, try another card". Again, there is no "secure element" message, just an error on the paypass terminal.
I tried it on the vending machines at my work and it erred. I then went to CVS just to try it there and it also said the card couldn't be authorized.
I called Google and they said that they see the transactions attempt to go through but show that the card is being declined at point of sale. So, it makes me think that it is not an outage on Google or even a secure element issue. After all, no secure element error code and if it at least attempts to go through, seems to not be secure element.
So, I figured it may be a google wallet outage. Nope. I then figured maybe paypass was down. Nope, it worked with other cards. But every time I try to use the phone it simply rejects the payment. And yes, I know the card my wallet account is linked to is still good...
I flashed a complete factory image back to stock unrooted and it still wont go through.
And I was also sure to always wipe the app before I flashed anything, so I don't think the secure element would have been damaged anyhow, but just seeing if perhaps anyone knows of a secure element issue or some other issue.
Thanks for your time and assistance.

On your phone, go to Wallet > Settings > Reset Google Wallet app, then clear the app data in settings.
Next, on a PC, go to https://wallet.google.com/manage/ and remove all payment cards.
Back on your phone, setup wallet and add the credit cards there.
I had the issue once on my Nexus S and this fixed it for me.

thanks. I'll give it a shot. Hopefully this fixes it. Seemed strange since I wasn't getting an error message but the point of sale is rejecting it. Google said it is showing up on their end as declining for expired card, but I know the cards aren't expired.
We will see. My main concern was simply that this is a Secure Element issue and perhaps the newest version of wallet just doesn't indicate it.
Ill report back soon.

I think the main issue with the secure element was related to the Google prepaid card. It stored the money in the SE, so the idea that you could put $20 on it, back it up, spend the money, restore, and spend it again would have become a cat and mouse security nightmare for Google.

Unfortunately no dice.
I wiped the app. Diabled it. uninstalled all updates. I went all out just to make sure to clear everything. And of course wiped all data from within the app itself prior to clearing data and cache, etc.
Deleted all payment info off of the google account using the link you provided.
Then I enabled the app, reinstalled updates and entered all new payment information. No dice.
So then I added in a card which I have never even had linked to the google wallet account. I figured perhaps just the card itself is somehow jacked up within Google network (expiration date or something). I tried the brand new card which has never been used before and it failed to authorize as well.
Im a bit lost at this point with other things to try. I do have a couple of old nandroids which I can try, but I am not sure if it will resolve the issue as I had already tried another one without success.
Any other ideas guys?

Only flash back to stock 4.2.2 ROM and re-lock the bootloader. Also try skipping the update to Wallet.
I'm actually on stock 4.2.2 now. I tried to flash factory image after it wasn't working on a custom ROM.
Boot loader didn't get locked though. I won't be able to try anything else until Monday though since the only readily available pay pass is on the vending machines at work.

Something like this did occur back when Google was providing Nexus 7 users with I think $10 wallet credit. People would restore their accounts (or maybe just sync a new account, not too sure), and get their credit again, essentially, infinite spending (within that limit)
Okay. So I am back at work with access to a vending machine with an NFC reader…
I have tried several things with no luck. First, I noticed there was a “verify your identity” section under wallet settings.
1) I verified my identity figuring perhaps it needed verification before it would allow any transactions. That didn’t work.
2) I have an NFC payment on 5/24 so I restored my 5/24 nand to try to see if that would restore functionality. It didn’t.
3) I then flashed the 5/25 update to the CM Nightly ROM I used on 5/24. I know I had done this so I figured I would try that. Plus, I have an NFC payment on 5/25 (last time NFC was used) so I figured I would try that. No luck.
I am really confused. I am not getting a secure element error, so I don’t think the chip is locked out. I called my CC company and they see the transaction come through and approve it, but never get a charge on it. Google also says they see the transaction request. This means the phone is sending the information as it should, which also makes me think the chip is NOT locked out. If flashing prior ROMS didn’t work, and flashing a complete factory image doesn’t work, it makes me think it has to be on Googles end somewhere.
I wonder if perhaps the virtual card I was assigned from Bancorp is somehow messed up.
another update. I added a new gmail account to the phone. Basically I created a new gmail just to try something.
I then reset the app, added the new gmail account info to the phone. I then set it up using all of my same payment information. Once the app was set up I tried it out at the vending machine and it worked.
So, since using an entirely new account works. This pretty much confirms that the app itself is not messed up and that there is no issue with the secure element either.
After I confirmed that the app works using a new account, I then reset the app, put in my actual gmail account again, and set up wallet again. This time it didn’t work. At this point I would say it is pretty safe to assume that it is definitely an issue with google wallet on googles end or perhaps on Bancorp Money Networks end.
I've been having this exact same issue with my Nexus 4. Still have not been able to fix it. I just tried setting it up with another account that I don't recall ever really having had Wallet with and that still didn't work. I have not tried to make a completely new gmail account yet. It's very weird, you'd think Google Wallet would just send the same info as my actual credit card does, the blink function in that one works fine.
I am having the same problem on my Gen Nex as well. Very annoying!
I've been able to use it in a few different places without problems now. I haven't gone back to these vending machines at work though so I don't know if Google ever did something after I contacted them. I was so upset when I contacted them because I explain my problem with as many details as possible, I am very clear about how I have a Nexus 4 and how this used to work fine. They reply back to me with some dumb generic message about how in order to use the NFC function in Wallet I have to have a NFC enabled device, which isn't even true because you can't use Google wallet on most phones NFC or not. Honestly it's like they just didn't read my email at all. I emailed them back asking if they even read the email but they never got back to me.
