Hello

I now have E3 flasher with dualboot 3.55cfw and 4.30ofw. To upgrade the OFW I figured was simply to do the upgrade.

How is the prosess if I want to upgrade 3.55cfw to the new 4.21cfw?
I do know i have to dehash the 3.55 firmware first, but if you try to upgrade the cfw, do you destroy the dualboot setup?
