Bricked Device, Black Screen, No Boot Logo, Nothing happens L-21

[mad_tom]

Hello,
after i followed this steps below.
http://forum.xda-developers.com/showpost.php?p=67816990&postcount=1686

After that i was able to boot "normally" with CM 13 version from 2016-07-19
I did a full wipe because of some force close.
Everything was running nice, i enabled the finger print.

This morning i installed 2016-07-20. (dirty flash)
after wiping dalvik screen turns black.

i already tried:

1. turn off your phone
2. put USB-cable in your computer (with drivers and fastboot installed)
3. press power + vol down and plug in USB-cable in your phone within 1 second
4. then you should be in fastboot mode (bootloader)
5. then you can flash twrp instead of stock recovery
6. then you can flash a rom or restore a backup
7. now you're not back at stock but don't have a brick

I am not sure if my phone is turned off.
I also tried to hold power for 10 seconds, 15 seconds 1 minute, longer
I got an usb amperemeter, it tells me, that the phone is charing with 0,09-0,24 A, while the screen is black

fastboot devices dont show a device
adb devices dont show a device


any ideas or suggestions? thanks in advance

Plug it into the PC hold volume Down and Power and wait until it boots in fastboot.

i have done this procedure two hours ago, ... one hour ago,... and right now again (
after done it for 5 minutes (every time), again and again... around 50 times?! still nothing happens...
NOW, just in this minute, it vibrate and fastboot start up.
i did a reboot via: fastboot reboot
maybe it was try #51, atm rom is booting up and android is updating,...
will it happen again after next update? or after next reboot? i'm a little bit confused.
at least, thx for inform me, still todo the same thing

What you can do is Flash an extracted update.app an then apply the update though dload to get Back to Stock and then to CM.
