I recently acquired a Z Ultra GPe and I'd like to convert it to stock. I've always been a stock Android user, but with the Z and Z1 I have, I found the Sony implementation to be awesome. Great look and feel, nice features, not a ton of useless bloat. That said, has anybody attempted flashing a stock ZU firmware to a GPe device? Any recommendations beyond "just try it and see what happens"? I'd rather not brick the device.
