Default Need help OnePlus One stuck on bot screen

Hey guys ! I need help please. Actually i changed my build.prop i followed this guide under my post, then reboot , but actually my screen is stuck on OnePlus One powered by Android , bot screen . Can you help me please. I just have acces to CyanogenMod Simple Recoverey <3e>
"Recently google gave a few devices the feature to cast your screen to chromecast, sadly opo isn't among the list.
But if you're rooted, you can do this mod and it will work, and it's pretty simple. You just have to trick the OS into thinking you have a nexus 5.

Edit the /system/build.prop
Find the line where says ro.product.device
Change "A0001" to "hammerhead" (without quotes)
Reboot
Open your quick toggles, and press the cast screen button
Enjoy!"

Thanks in advance !

EDIT : Resolved , you can close this post , thanks.
