iot phat not updating from 0.3 to 0.4

[Hindosh]

After following the update instructions for iot Phat 0.3. to 0.4
the cat /proc/device-tree/hat/product did not show the update?

Still says v0.3:
pi@raspberrypiX:~ $ cat /proc/device-tree/hat/product
IoT pHAT w/eep_v0.3pi@raspberrypiX:~ $

I did run the 0.4 install instructions?

After the update, did you reboot it?
I tested without any issue.

Needed to remove the old installer scripts in root. then followed the instructions and update worked
