No Download Mode,Stuck in TWRP....Please Help!

[Use2]

Hey,
in the last days I experimented with many Roms and Kernels.When I installed a Lollipop Rom I got a mounting Fail in TWRP,i didnt think bad and got back to Cloudy G3.So today i wanted to flash Cm11,but i recognized that my USB-Stick isnt recognized as normally,but i were able to install Cm11 from my the USB-Stick..So I get into TWRP and flashed Cm11.But after installing Cm11 it didnt start,i get after Lg-Logo into TWRP.So i flashed Cloudy 2.6,the same ****.Then i tryed to get back to stock,with download mode,but my download mode is away,when i want to boot into download mode,i get the download mode picture for some second and get into the Fastboot then.My Pc recognizes the phone.
After that i tried to do that:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc

My Phone is a Vs980
After that,nothing has changed....
Please Help me,i wanted to brick my second mainboard again.....Sorry for my bad english.

Do you have any backup? If you can access rec just wipe everything except internal storage and it should work

The Problem was,that my USB-Cable was broken,so TWRP cant mount it and so the rom couldnt be installed,i use ADB to get the Rom on my Phone,everything worked...
