Database [Q] Broken Huawei Ascend D1 U9500. how to retrieve data?

Hi.

I have broken Huawei Ascend D1 U9500 with very important documents in internal storage. Screen and digitizer doesn't work. OS and Recovery doesn't working. If I connect my device to computer, D1 buzzing every 5 seconds. If I'm trying to boot in fastboot mode, my device booting correctly, but I can't flash any file. Phone starts buzzing again.

Thanks.
