I accidently damaged the recovery partition on a LG G3 D855 with Lineage15.1
OS was still booting ok, but I wasn't able to get TWRP on recovery again, as the device was not routed. I used a one-click-rooting tool, that returned ok.
Now lineageos hangs with the green crescent while booting.
Trying a factory reset leads to a black screen with the message "fastboot started" than hangs.
ADB cannot access the device.
Is there a way to recover the device?
