At one point it would only show the boot screen for CM9. I had to create a folder in my sd card "/clockworkmod/backup/" and put my backed up rom in there. But I was lucky I had clockworkmod to begin with, it took me forever to figure out how to boot into it. I looked around for the recovery boot mode and nothing worked.
CM9 does not give me cell service or wifi service, can't find any carries, says there was an error. So I switched back. But if there comes a stable version that works on it, then I'll switch over.
