I'm sure this question has been asked before, but I'm unable to find a good answer that I can understand, so bear with me:
I've recently installed TWRP & LineageOS 15 on my Moto G5 (cedric), although I'm sure I messed the process up a bit, because I had almost-bricked my phone in the meantime and don't really understand how I solved it either. Now everything is working again, except for the fact that when I (re)start my phone, it automatically boots into TWRP instead of LineageOS. The way I boot into LineageOS anyway, is to tell TWRP to reboot into the bootloader (or go to the bootloader directly with the volume key trick), and then from the bootloader I use 'start'.
A possible solution that I've found on the internet involved changing / erasing the misc partition, as it would be responsible for directing a boot to either TWRP or LineageOS. However, other google results tell me that erasing misc could gravely upset your phone.
The main question is: Is it correct that zero-ing the misc partition is a solution to this boot issue, as the possible solution states? Or is it misleading and the boot issue is probably something else entirely?
Here's the hexdump of the current contents of my misc partition (the result of first copying it to my computer with dd if=/dev/block/bootdevice/by-name/misc of=/storage/FE84-1705/misc.img and adb pull ..., and then running hexdump -C misc.img):
hexdump -C misc.img

And this is the result of running fdisk -l misc.img:
Disk misc.img: 1 MiB, 1048576 bytes, 2048 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Furthermore, I've installed TWRP 3.2.1-0-cedric and LineageOS 15.0-20171125_073252-UNOFFICIAL-cedric.
