My phone was rooted then it updated to the 4.3 and when i reset it because the galaxy play store was not working i tried to re root it and it got stuck on a screen upon boot that says Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again. But when i go into Kies it just tries to connect and does't not recognize my phone. I need help on what to do please, I have tried everything.
