Hi, I really am a SuperBaka (a Super idiot :crying: )
I tried to install Gapps to my new Asus Zenphone 5 (A500KL) by this method :
Which is:
1.Root your phone
2.Install Root Explorer
3.Unzip Gapps and Copy SYSTEM Folder to Internal memory
4.With Root Explorer paste SYSTEM Folder over original SYSTEM folder
5.Reboot

I followed each step, until the 4. But unfortunately, instead of copying, I erased accidently my original System folder by coping into Internal memory.
After that, all the apps closed and since that when i turn ON my phone, I only can see the Asus logo...

Please help me to reinstall Android, I have this phone since only 2 days... I really don't know what to do and i panic beacause i don't have any warranty (bought on To2c.com)

PS: Sorry for my english, i am french (tell me if you didnt understand something)
PS2: It was on Android 4.4.2 Kit kat version
