Bootmenu after update ...

Hi Guy's,
After an update on my new Elephone P7000 (lolipop 5.0) I am stuck in the bootmenu ... it did say "Error!" and then "no command" .... So i am in the bootmenu:
Android system recovery <3e>
Elephone P7000_20150608
Volume up/down to move highlight;
enter Power key to select.
-> reboot system now / apply update from ADB / apply update from sdcard / apply update from cache / wipe data/factory reset / wipe cache partition / backup user data / restore user data / root integrity check / reboot to bootloader / power down / view recovery logs ...

I did a root integrity check and this failed:
Error:/system/app/Superuser.apk is new it is created on Thu Jan 1 00:00:00 1978
Error:/system/bin/su is new it is created on Thu Jan 1 00:00:00 1978
Error:/system/etc/install_recovery.sh is new it is created on Thu Jan 1 00:00:00 1978

Error:/systemxbin/ksud is new it is created on Thu Jan 1 00:00:00 1978
Error:found 6 new files
System check FAIL!

Nothing works whatever i do and because the system can't bootup, i can't install or desinstall anything!
Is there anyone who can help me please?
Kind regards
