Android (6.0-01003) update failed

Hey,
A month ago i got the message on my Alcatel (PIXI 4 (5) 3g) that he needs to update...
So i just go to the standard update app and pressed download.
After a little hour (yes, i know i have terrible wifi) he said the update was downloaded,
so i go again to the app and press on install.
First he verify the package and than the message "Android is preparing the update" comes up.
When the loading bar under that message is completed he shut down to the flash recovery (no, i didnt installed a custom one because i have still some waranty and when i root my device the warranty is gone).
Under the menu the message comes up:

"Supported API: 3
Opening update package...
The update.zip is corrupted
Installation aborted.
OTA failed! Please power off the device
to keep it in this state and file a bug
report!"

So...
Yeah maybe got the same problem or just knew a solution because i like to have my device updated for many reasons
