Apparently I first encountered the marriage on this unit. In general, after unpacking tried to go to fasbut for TWRP firmware, but when you press the power key and the volume "-" nothing happened. Reboot, and I checked the volume buttons, and found that they do not work. Perhaps it was necessary to send him back to the sell, but this experience was not there, and the risk of losing body when smuggle back and forth great. I gave to repair the diagnosis where found that when assembling the "unscrupulous Chinese" damaged the loop, that's just half torn! The power button works, and both Volume buttons do not. I am trying to find a button on alliekspress, but to no avail, even though there are similar from redmi 3 (in appearance), but if the issue will do. Perhaps all the same offer, since there are 200 rubles If someone tell me where to buy, will be grateful :)
