I've been trying to find something to fix this, but can't. Basically it's stuck in boot loop after a bad flash. I took the battery out and when I put it back in it goes straight to boot flash and stays. When I try to go into boot loader it buzzes 3 times and then nothing but flashing amber light. Someone said take the SD card out and then boot, but no joy. Any help is greatly appreciated!!
Forget it. After nearly 30 times trying to get into recovery, it finally worked. Not sure what was different, but go it.
