Edit: looking into possibility of CardActivity being a player in this lockout issue.

I've relentlessly flashed, and re flashed my phone, never resetting Wallet in between. I have never added a card using the app; I had my card linked through the normal wallet website prior to installing GW. I've made purchases both before, and after flashing and have never had any difficulties. After flashing a new ROM and running GW for the first time, it goes through the process of initialization and linking up to my Google acct. After that, it has all my previous transaction history, my credit card, and is able to make additional POS purchases with no problem. The mystery continues...

I gotta agree, before ever reading this post I had rooted, unrooted, flashed and reflashed back and forth between LJC, MA5 several times, installed TWRP and now I'm on MA7, i have had a working Google Wallet on all of them with my month old GN2. I never uninstalled the Google Wallet apk before flashing nor have I disabled the device on the GW website and I still have never encountered the Secure Element error! Call me lucky but the error doesn't seem to be concretely linked to flashing without following the OP instructions!

I went from lk8 stock rooted to ma5, used google wallet once then reflashed back to lk8. Now running ma7 and have the secure element problem. Just fyi. Did not see that google wallet was anything so special but it would have been nice to have.

So, would the prophylactic measure be to take and keep a nandroid backup of your device while Wallet is working?
So if Wallet borks, reverting to the nandroid should fix it?

I want to go to MA7... now I'm paranoid.

Once you have the SE error, you are done. This so-called preventative measure (resetting GW before flashing) is nothing but wishful thinking. I could say that my GW is working because I eat McNuggets before I flash, and it would have as much validity as the claim that following this guide will save your Secure Element.

I am getting a replacement note in 3 days. I won't make the same mistake twice and bork my secure element again.

I remember the same thing happening with the Evo LTE when it first came out. I borked my first SE the same way. Thank goodnes for BB insuance. Not sure what actually fixed it but I think Google pushed out an update itself that stopped the whole SE from getting messed up. Afterwards I flashed constantly without resetting my Google Wallat and never had any problems. Maybe a look over in the LTE forum can answer the questions.

To date there are only 2 known truths regarding this issue.

#1 If you get the message "The secure element stopped responding". Your GW will never work again on that phone.

#2 No one has a clue how to reproduce bricking the secure element. It just happens.

IMO It's cheap nano memory storage on the chip that goes bad. Could happen anytime data is written or cleared from it and can happen at any moment for no reason.

Mine broke. No flashing, no data wiping. Was working until it wasn't.

Re: [WARNING][You MUST Reset Google Wallet When Switching ROMs!]
It's also worth noting that the Secure Element, by design, locks down if it perceives tampering. The condition can be triggered either physically, or via software (i.e Google Wallet).

I believe there are multiple causes of a "lock out", and I have successfully replicated one. Resetting Google Wallet (as is recommended prior to flashing), flashing a new ROM, and restoring Google Wallet from backup will lock the Secure Element. In trying to trigger the condition, I came across this sequence and confirmed it on a second device. I can also say that, based on my own repeated flashing and attempts to trigger the lock out, I do not believe that resetting Google Wallet prior to flashing is necessary. As long as a fresh copy of Google Wallet was installed on the new ROM, I always got through setup without trouble.

Finally, I can confirm that S Beam does not work once the SE lockout had been triggered. This is a good thing because it provides anyone with a borked SE a legitimate warranty claim. Samsung phones come with a 1yr manufacturer's warranty. RMA's can be filed online without talking to annoying reps, and their turnaround time is 10 days. I suggest that anyone with a locked out SE who purchased the phone less than a year ago, go to the Samsung website and file an RMA for your phone. Get it replaced. You'll have to use a backup for a few days, but it's better to take care of it now while you still have the warranty.

I got my replacement phone. Sprint gave me a new phone in the box with an extra battery. I installed Google Wallet and it worked straight out the box no problems. If your Google Wallet is not working on MA7 get a replacement phone. Installing Google Wallet is not suppose to be difficult if your phone is working correctly. Now I got my swagg back and I am now 20% cooler.
