Okay this is what I did.
Had OFW 6.39 psp 1k.
loaded up this hen: HEN 6.39 EZ for all PSP models. 6.39 TN Mod, PSP Hacks - PSP Slim Hacks
Then ran neuron's 6.60 me stable Custom Firmware 6.60 ME-1 Stable, PSP Hacks - PSP Slim Hacks
After I installed it. I try to turn it on, green light comes on, but then shuts off.
I have a second psp 1k on 5.50 prometheus v4 so I can pandora battery.
If that's the only solution, can someone point me in the right direction. I've been away from the scene for nearly two years.
Please and ty.
EDIT: Just tried booting by holding home button, and turning on. Boots to OFW 6.60. Is the CFW corrupt or something? I still want CFW
