PSA: Clear Google Wallet Settings Before Flashing ROM/Hard Resets!

IMPORTANT! Please read!

While waiting to get my hands on one of these awesome phones I've been reading all I can about it. One thing I ran across in another forum was an issue people were having with the Nexuses & One X's and Google Wallet.

Apparently if you do not clear the Google Wallet settings before you do a hard reset/ROM flash, the secure element in your NFC chip will be FOREVER bricked and you will NOT be able to ever use it for secure purposes (google wallet purchases) although it will work for other things like Beam and such.

For some, this wont be a problem, but if you ever plan or at least want to have the option to use the google wallet, follow these simple steps before doing a hard reset or flashing a new ROM on your phone:

Launch Google Wallet
Hit menu button> Settings> Reset Google Wallet

Clearing the app data or cache through settings or Titanium WILL NOT WORK! It HAS to be done within the Wallet app. This resets the secure certificate (?) and allows NFC to be used for secure purposes in the future.

---

While I understand the notion of keeping such functionality very secure, Google should have expressed the potential problem. Especially since hard resets are used as a solution when an ordinary user has a problem with their phone.

Also, forgive me if there is a thread on the Evo LTE forums about this, I tried searching and nothing came up, furthermore it's late and I did think this warranted utmost attention since people already have LTE's in their hands!

Yeah what I couldn't find and am interested in is if there is an actual partition on the phone with this info or its stored in the NFC chip itself, and whether it's a certificate file or what.

It would be nice if there was a way to do this through the recovery, then devs can cook the wipe command before flashing their ROM.

EDIT: I'm sorry xD I meant to post this in the Evo 4G LTE forums, I was lurking both and accidentally posted it here. It is no danger to us since our 3D does not have a NFC chip, but if you're upgrading to a Evo LTE, please read. Mods, you can close, my bad.
