I go to check my emails ect but find out my phone isn't turned on. I try to turn it on, but it's not doing anything, not even the low message screen when it needs to charge. I start becoming confused. I plug it into my wall outlet and it doesn't do anything. So I plug it into my computer and it recognized it only once, the first time. It says it was in DFU mode, so I install iTunes (uninstalled for a reason) and click restore. Since it said I would have the option to restore my contacts and other settings I gave it a go. It downloaded 4.3.3 and attempted to install. Then it gave me an error message. "Not enough space on disk" or whatever. Since I had ~1gb of space left on my boot drive (apparently apple cannot have the option to move firmware downloads to another drive) and now had 20mb, I figured it was my main drive. I delete as much files as I can to make space for the firmware and iTunes and attempt it again, all while my phone was plugged in. This time I had ~500mb space left after the firmware was downloaded. I continued to repeat the process only to get the same error message. Tl;dr I wake up to find my iPhone 4 in dfu mode, unable to restore with error message "not enough space on disk" when there is. Note I had dropped the phone in the toilet about a month ago, but it shouldn't be affecting it now.
