I made the stupid mistake of installing so many tweaks on my iPad 1 that it didn't have enough room to operate. I tried respringing; didn't do much, and when I went for the full reboot, it wouldn't boot up. After running some preliminary diagnostics, I found that there wasn't enough ram to boot. I need it running to trade in,don't care if I have to wipe the memory. It just stays on the apple logo, and doesn't show up in itunes. What can I do to fix this?
