use Aaf recovery tool you can change the ID of the Maxi bootloader to Octagon and after that you can install the Octagon Firmware on the normal way (USB stick). then to change to boot loader back to octagon name use HDF flaser V223 I've done it, you do it at your own risk. so i just pass it on thats what other help in the same boat as me i hope this helps.. thum:
