Hacking the free ANZ fitness band
Some of you guys probably heard of and ordered the free ANZ Olympic support bands few weeks ago.

Like everyone else, I was excited and ordered two for me and my wife.
When it showed up, I was really disappointed. The only functionality the band has was literally show time and send vibration.
As a ANZ customer, thinking that my money has been spent on this thing just wouldn’t let me through. So, I decided to have some fun with it.
Upon looking at some post on Choice Cheapies and searching for similar band, I figured out that these band were actually named H707. I have confirmed this again, by checking the Bluetooth broadcast name of the band, which was “H707”
This band was based on Nordic Semiconductor’s famous NRF5283X chipset, which I had some experience with. Through this helpful post on Choice Cheapie, I have gotten hold of the firmware distribution package zip file. https://www.cheapies.nz/node/28151
So, here is the step by step guide to update your fitness band. Hope this finds more use.
