I understand this, it is clearly posted on the thread's OP, which is why im asking how the heck seawolf823 got H/K on T-Mobile, unless he's on a custom rom. Maybe im not reading clearly or everyone seems confused as to what im asking. I have the habit of doing as much research as i can before i lose patience, well in this case the OP-er hadn't added the prereq for 1.54 to the OP till like the day after i attempted the mod. anyways, not trying to start a war here.
I guess until US carriers start updating to 1.54, my question now is what custom rom supports AT&T or T-Mobile ISIS and is compatible with H/K?
You need an xposed module to hide root from ISIS because it won't work if it detects root. Also from what I've seen no ROM includes the nfcee_access.xml that contains the ISIS signature, you would have to push that yourself.
Why not just use Google Wallet?
