Cannot enter recovery mode after updating CM13 nightly

[flo_z]

Hey guys,

I feel totally stupid for writing this post but I'm actually out of ideas how to get out of my situation. Also I didn't find any comparable topic here on xda. So let's hope you can help me and a big thanks in advance!

First of all i have a flashed D802 running TWRP and CM13, which worked well the last weeks. I thought about updating to the todays nightly as it is already a few weaks since I did my last update. I downloaded the nightly via the CM downloader and started the installation with running phone. It rebooted into recovery mode and installed the nightly without any problems. After the installation was completed the phone automatically rebooted and this is where the problem starts.

I am stuck in "bootloop?" at the CM logo. It is not automatically restarting after a while but just loading and loading and nothing further happens. I am not able to enter the recovery mode via the factory reset (Pressing Vol Down + Power, releasing after the lg logo appears, pressing and holding the power button again).

This never happened to me and as I am not able to enter TWRP I am not able to install a previous release or a backup. What am I doing wrong this time and what can I do?

Thanks for your support!

In the meantime I managed to enter the recovery mode / TWRP via a mode I don't know how it is called. I pressed vol down + pw btn, released after the LG logo appeared and pressed vol up + vol down. I guess my userdata is deleted by now, which shouldn't be a big deal but I am getting redirected to the recovery mode. I tried to install the yet working CM13 nightly but it has the same problems now.

Now I have two questions:

1. Does anyone know which part of the system is broken now / which part I need to update in order to get my phone back to life?
2. Is the download mode working if my phone is rooted? I am able to enter this mode.
