Btw gen d3 is out

i upgraded directly from 5.00m33-6 to 5.50gen-d3

1. Use hellcats recovery flasher to backup your fw incase of brick

2. Format flash 0 and reset settings from the recovery menu

3. Run the 5.50gen-d3 installer

worked for me 1st try.. No brick

good luck.. I take no responsibility if you get bricked useing my way
