Someone with 3.73

[cuccio123]

Does anyone actually make any custom firmware that can work on the version 3.73? and dont say downgrade because everyone knows what to do to do that, but costs too much $$$

all CFW works on all PSP's.

There is no 3.73 CFW. The only way to install CFW without Pandora, is if you're already on CFW or if you're on 1.5. Any other firmware, you need Pandora/Magic Memory Stick. And all firmwares work on Fat PSPs. 3.60 and up for the Slim
