I unfortunately lost my old SD card recently. It was a 32 gb micro SD in an adapter. I used it to run ML on my T1i for about a year. I remember using a 2gb card to upload ML initially to the camera, and then switching to the 32 gb card because the 32 would get stuck on the loading screen. I now have an identical 32gb micro sd in adapter setup, and I have started from scratch with a standard firmware 1.1.1. I used the 2gb card for the initial. Then used my 32gb card (made bootable with macboot) and the screen becomes black, the camera is unusable. I have reset the camera many times, and tried different methods, but nothing seems to work. Please help...
