Hmmm... I admit I did switch boot config a few times... My "stock" is not so stock as I tried a couple previous hacks to get Playstore working.
My Slot 1 has play store working, but no Amazon.
I setup my slot 2 two days ago and at first, got both Amazon and Google to work. I rebooted back to slot 1 to backup all the apps so I can restore them in slot 2 with TiB.
So you're saying that would have caused my Slot 2 to become unregistered? How interesting!
So Amazon is keeping track of both serial number and the Android device ID, which changes from ROM to ROM?
But it's still the same device serial number, right?
So it can Probably be overriden, like TiBackup offers to restore your old ID?
