I removed this lines and installed the ROM. Boots normally with bugs:

• No SIM card detected

• No Audio (Fixed if the files from firmware-modem and firmware folders manually placed on the /system/etc/firmware)

• Gallery FC when play any video

• Google Apps FC (Setup Wizard and Play Services)

Tested on M variant.
