I'm sharing to you Odin v1.84 that you can use to flash kernel on your android galaxy y phone. You can use this only by running this program using a computer. This v1.84 is the most stable and compatible version that you can use to program your galaxy y to flash custom or stock kernels to program your phone or to make your phone working again after it has been bricked (stuck on galaxy y logo).
You need to use this wisely since custom kernels will add to bin count ( which will be bad for warranty). Otherwise stock kernels will not add to bin count and will just update the phone's system files.
