I get an error message after I installed my firmware

[AC Question]

I recently updated my firmware to 7.0 with Odin but I cant boot my phone. When I try to boot by pressing the power+vol up it says recovery booting.... and it then goes to a screen that says error that has a picture of the android robot. My phone then turns off

Welcome to Android Central! Which phone? Are you certain the firmware you used was for your exact variant? Installing a firmware for a different variant can potentially cause problems.
