running hellcats recovery flasher should allow you to install 5.50 gen-d3. according to the documentation it "runs fine on CFWs lower than 3.52-M33-3 – handy for upgrading older FWs w/o the “need to go 3.52, then 3.52-3, then higher” odyssey :)". the only other thing you may need is the ofw 5.50 updater.

you can download the latest version of hellcats recovery flasher here:

ofw 5.50 can be downloaded here:
