THL W5000 problems getting stuck on Boot, adb unauthorized/offline

Hello there Guys,
I already postet this in the XDA Assist Forum and I got redirected to here. So here´s my problem listed below. Hope for help from the Pros.

After I flashed a few tons of phones, this one gets me really p*ssed of. I can´t acces the THL W5000 with ADB, I can´t mount the SD-Card because in Recovery there is no Option for this to do so.
I cant push/pull files to/from the Phone. Got no luck with fastboot and it gets stuck on Boot screen, so I can´t accept my PC for adb to work.
And what I recently found out, the Bootloader is locked, so I can´t even Install from SD-Card. I got a new SD-Card with ROMs and TWRP, the Recovery is able to read the SD, but when I launch a .zip, it
suddenly appears the Message (in Dropbox the last Image):

Code:

---

-- Install /sdcard ...
Installation aborted.

---

I need help asap

When you need more Info please ask I will reply asap.
