I've made a topic about not being able to boot earlier but that one's deprecated because of all of my tests and all so here goes nothing:
I've tried getting my new rPi to work for a whole day by now to no avail. I've tried using NOOBS which goes into panic kernel right away every time(Even after formatting and putting a new one on the SD card). So I've decided to give Raspbian(Wheezy) a try.
I got Raspbian to work once with only my HDMI cable connected to my TV. I got a BIOS-type window for which i needed a keyboard, obviously. So i plugged in my Apple keyboard and it went to the rainbow screen and froze.
After that I've tried a million reflashes of both NOOBS and Raspbian but I just can't get it to work. NOOBS still goes to kernel Panic and Raspbian freezes on rainbow screen. I have NOTHING connected except for my HDMI cable. And even without an HDMI cable my power LED is the only one lighting up(RED).
I've got a 5V adapter along with my rPi(It said it was suitable with model A and B) so I can only assume that that's settled. I've got a 4GB SD card from the same supplier(Which they even pre-installed for me with NOOBS which didn't work anyway).
I even went as far as buying a new keyboard and mouse from the verified peripherals list on elinux.org, but I haven't received those. Until than i figured I could just see if I could get my rPi to work with a newly installed Raspbian. And you've guess it: To no avail.
I'm on the verge of breakdown by now and am willing to either throw the rPi out the window or return it to the supplier(Which propably is the better deal).
Does any of you have any suggestions what I can still try now?
Before more people start giving ideas:
It was an actual defect in the rPi, they took it back and it was refunded
