Huawei Y625-U51 Android 4.4.2 - Problem installing Xposed Framework

Hello! I tried to install the Xposed on my smartphone but it gives me the following error:

"SD card: / storage/sdcard0/Android/data/de.robv.android.xposed.installer/files

Copying Xposed-Disabler-Recovery.zip...
Mounting / system writable...
Backup already exists at / system/bin/app_process.orig
Copying app_process...
Copying XposedBridge.jar...

Done! Changes will become active on reboot.
Do you want to reboot now?"

After I say yes but the Xposed is not properly installed.

What should I do to solve this problem?
