after flash custom recovery
no recovery and no boot
only download mode
Can you more explain what you exactly flashed? What's your phone model (GT-i8190/N/L)? Was the recovery.img really compatible for your phone model?
BTW flash a original stock rom via odin3. You can get stock roms from sammobile.com/firmwares.
