Problem after swapping hard drive from slim

I had CFW kmeaw with the latest rogero working just fine then I backed up my hard drive onto an external and swapped my PS3 with a bigger hard drive. The restore went just fine but rogero isnt working now. Every time I try to open it the PS3 will just refrech back into the main screen again. I had to download OFW 3.55 and install it through flash drive first but the CFW should still work since it was on my backed up external shouldnt it? Everything is still there but its just not working. Any ideas?

I got it. Was told had to install CFW again. Everything is working fine now.
