exec '/system/bin/sh' failed: No such file or directory

Hello.
I built CM11 for my chinese tablet Onda V989 and i successfully flash my rom via CWM. (I wipe data & cache after flashing).
After rebooting it stuck on the bootloader logo. (I think that it happens because system partition was not mounted correctly)
Then i tried to get logcat but i got this error:

Code:

---

exec '/system/bin/sh' failed: No such file or directory

---

Then i checked otapackage which i built ands i found that sh file did not exist. It is strange.
Any idea?
Here is a my device tree which i used for building:
device folder
vendor folder
kernel folder
