Default Galaxy mini 2 serious problem

So, i have an s6500 galaxy mini 2, when i try to turn it on it bootloops, but, it can enter in download mode. so i tried to install a stock firmware via odin but it did not sort out the problem, in fact it still bootloops and cannot access to recovery mode, if in fact i press home+power+volume up it continues vibrating and do not go in recovery mode, beacouse when i release the bottouns the telephone dies. so i tired to flash a custom recovery, but the problem are still there, can someone help me?
