I finally received a handful of PADI modules last week and spent a little quite some time over the weekend analyzing the OTA update and firmware recovery methods. Generally speaking, the firmware on the PADI is an improvement over the one on the B&T modules, but there are still a few caveats involved. 

First, a few definitions:
Bootloader (BL) / Img1
First stage image loaded by ROM code, always located at flash address 0x0. No source available in any SDK.

Img2
Runtime firmware image, loaded by Bootloader.
