keeps stoping at the samsung logo
It would be rather unusual if neither Recovery mode nor Download mode worked. It may just be that you're not familiar with how to get into those modes:
- you use Recovery mode to clear the system cache and to Factory Reset
- you use Download (aka Odin) mode (showing the Android guy) to load/reload firmware
- the key sequences to enter both modes are very similar, and they are timing dependent so it may take a few tries to get it working
-- Recovery = Volume Up + Home + Power
-- Download = Volume Down + Home + Power
- for either, you start with the phone completely off
- press and hold the required keys simultaneously, and release them all when you see the swirling logo (not the static white text)
Try Recovery mode first (use the Volume rockers to navigate; use the Power button to select) and if it boots into this mode just clear the cache and then restart. If the phone doesn't boot into Recovery mode then try Download mode. If that works, you can try using the Kies software to reload the firmware.
