First question on here. I've seen others with this verification problem but I couldn't find an answer for the Moto 2G XT1064 specifically. I've gone through all the prior steps, unlocking the bootloader, setting USB debugging to true, installed Moto 2G drivers and android drivers, and so forth. (However, the "OEM unlock" developer option doesn't exist on my Marshmallow 6.0).
Anyways, whenever I try to flash/install SuperSu.zip, I keep getting this error:
verifying update package... E:failed to verify whole-file signature E:signature verification failed installation aborted.
It doesn't matter which SuperSu version I flash, 2.68 or 2.65. It still gets that error. I don't know how to get past the verification failure. Anyone have any clue? Thank you!
EDIT: I use titan-24.11.10-BR-boot.img
