Map of CF-Mode initiation places
From A complete guide to Super Metroid speedrunning
Map of all rooms (with corresponding room states) in which it is possible to obtain CF-Mode (via simply executing a Crystal Flash [when at least already 1 fireflea is dead during the CF, in the case of fireflea rooms]):

In the green rooms, the room state does not matter, and one can obtain CF-Mode there. For the orange rooms, those rooms have to be in their inactive state in order to allow Samus to obtain CF-Mode in those (i.e. Crateria and BlueBrinstar needs to be unawakened for the orange Crateria and BlueBrinstar rooms and Wrecked Ship needs to be inactive for the orange rooms in there).
