I own an i9500 (Galaxy S IV). Recently, it dropped. I was lucky enough to install RomSwitcher (a multi-boot app) on it before, so I could still access an Android version.
However, in order to fix the problem, I decided to format the whole device. That didn't work out, and now I'm always stuck on bootloader screen( if it boots at all) and data partitions give I/O errors in recovery.
Now I would be glad if I could install another ROM on my sdcard, probably that'll have to go via RomSwitcher(). I would be glad if someone could send me the kernel and recovery images.
p.s. Logcats give the issue of Constantly being in wakelock because of the GPS.
