I had the exact same thing happen with iatkos l1. Apple screen flashed for 2 seconds then it reboot endlessly. I finally got it to run when I installed the right version of Chameleon Bootloader. You need the new Chameleon 2.0.


I had RC5 installed, hence the reason it wasn't working. As soon as I put the right bootloader Chameleon version, iatkos L1 came right up, and might I add with a cool background, and icons.

For the life of me, I couldn't figure out why it kept looping! Hope this helps. Let me know!
