My K610i won't turn on. Red light flashes n won't charge.

HI,

That indicates a problem with the battery.Try a reset first.

Connect the phone to the power adapter and then press and hold the power button for more then 1 min.If it still doesn't turn on then remove the battery and sim from the back and then insert the sim back again and hold the power key for more then a min.Make sure you don't insert the battery now.Let me know the result.

Thank you
