How can I recover my phone (factory reset doesn't work)?

My phone is Asus Zenfone 5 and I want to recover my phone but I can't because it always stucks in the screen with the Asus logo. I've tried recovering it by using the factory data reset in the settings and a hard reset but it just stucks on the Asus logo. I also have heard about recovering it on a computer but I couldn't find the link to download a suitable recovery version for my phone. Notes: - I use Android 4.3. - My phone version is: > ASUS_T00J_WW_user_1.15.40.35_20140715_3835release-keys 010175_201401130121
