xrgn,34,1:/34.bin
Where 34.bin is region 34 backup. From offset 0x10 are not FF, but some info.
And, even startup screen shows 34xx, BT is working.

Yes, it works. That's how I cloned a 3450 device and converted my 3750 into a full 3450. BT looks like it is working but it is not. If you disable it and try to re-enable it in the BT menu, it won't because the BT chip is not soldered on the board.
