NOTE: ROM is now based on OOS12 fw. Do not try to dirty flash from 3.9. Follow fresh install instructions.

Dirty flash is fine if coming from version 4.0

Nope.. twrp is not fully functional for A12. Use the recovery mentioned in the thread.

Maybe try using recovery from arrow os thread. I don't know why you are facing this issue. I do not have this device to test but the person who tested the ROM on op8 did not face any issue in sideloading

Trying to flash this and getting a message in recovery that it was expecting instantnoodle p but got instantnoodle. I am on an IN2017 it shows as that in device info. Not sure what I'm doing wrong. I am using the linked recovery.
