So i'm getting an error when i try to flash the pre-rooted boot image from the other thread. I cross-flashed the ULM oreo rom, then followed the EDL guide and now I'm bootloader unlocked. When i try to flash the image via fastboot i get this error: fastboot: error: cannot get boot partition size. I can't extract the boot image from the kdz linked in the thread, there's an issue using the firmware extractor. What should i do to get past the error with the pre-rooted boot image?
Use qfil to load the rooted boot img in partition manager.
