Ok guys, I'm hitting a problem and figured I'd come here for some advice. I'm running a Samsung Fascinate on Verizon. I had rooted the phone previously, but had to send it in for warranty replacement (cracked screen) and on the new one I've left it completey stock until now. It's running latest stock setup (ED05). I am hoping to get CyanogenMod running on it as I've had a lot of stability problems with the stock ROM. Following their guide, I've downloaded and installed ClockwordMod Recovery 184.108.40.206 using the Heimdall Fronend. I have downloaded CyanogenMod 7.1 as well, I've rooted the phone with SuperOneClick, and have ROM Manager installed. I've about ready to go, but I can't get ROM Manager or ClockworkMod Recovery to load - I'm getting a "Signature Verification Failed" error. Based on my Google-Fu, I've deduced that the stock kernel won't allow unsigned code to run, and that I need a new one, but I'm having issues finding what kernel I need to install to enable this. I don't want anything too exotic - just something I can install and be as close to stock for now as possible - just looking to be able to run the unsigned code. I found several kernels online via searching, but a lot of the posts were older and I was hesitant to install anything referenced too far back on a newer system. Also, whatever kernel will work - can that be installed using Heimdall? It seems to have an option for it. I know a lot of people use Odin but it seems to be Windows-only and I'm on Ubuntu. Thanks!
