Default [Q] Phone won't boot after flashing

Hello guys,

I hope somebody can help me with my problem.
I rooted my Z1 today and then decided to put CM11 on it. The rooting process was fine. I did towelroot and installed the dualrecovery that was recommended.
The problem was after flashing. The process itself seemed fine but after it was done the phone didn't boot. I also can't go into recovery again, which seems a bit strange... When I connect it with my computer Flashtool can detect the phone and it seems it disconnects and reconnects periodically (typical Windows sounds).
For Flashing I did use Philz Recovery I think and CM11 the latest nightly with the latest GApps.

What would you recommend?
Thanks for the help!

Best regards
Kacha13

Quick sanity check: you've unlocked the bootloader, right? CM cannot run under a locked bootloader.

CM 11 requires unlocked bootloader. Unlock bootloader allows users to install custom kernels that are necessary to boot CM 11. regardless the issue with your phone, if it still reacts to powering up, do the following steps to repair your phone

Do a hard reset. hold the power button and volume up key for 10 seconds,or until you feel 3 short vibrations.

Download sony update service and try to do a reinstallation of stock firmware.

this will remove root and all data with it. good luck

Doesn't Towelroot unlock the bootloader? Or did I misunderstand something here?
I think I did the hard reset already accidentally. Will the Sony Update Service work if I wiped the previous system with the Recovery Tool?
I can't test it right now, only later that day.

But thanks for all the help! I really appreciate it!

Towelroot does exactly what it's called, root your device.
It's not called towelunlockbootloader

You, sir, are awesome!
It's working fine again. Now, I need to do this step by step and unlock the bootloader before flashing CM.

Thank you again!
