M6 firmware in m5?
Sorry, i will not work

And i will update the post, i tested it in wifi network and in phone network, battery is draining fast even if you are not using it (turn on hotspot to use wifi in other phone, battery drained quickly).
I calibrated the battery and i am checking it again to confirm.

If what you said is true and you have not forgotten anything, you have convinced me, congratulations! But I would like to ask you a question: what happens if you try to install the M6 Firmware? It works?

Good review. Hope it will for m3 note too...
