I've tried them on the Lithium and Chevy's 4.7. Now maybe I don't have the latest/greatest, I have only one page for downloading his kernels but lately every time I apply one, the phone reboots and there's a solid red LED light and a battery error icon. It never gets to where it boots to a homescreen and it shuts down. Now with non-Chevy ROMs I'm ok with it, I've been utilizing P3 kernels but i'd have thought they should work on his ROMs. I almost went through an entire battery trying to get the phone back up with all the restoring and trying other kernels. Anyone else run into this?
