小米红米 Note 7 电池更换

Thanks for the detailed guide!Unfortunately I wasn't carefully enough when wedging the first opening pick below the glass back cover, and it cracked. I was still able to follow the guide and replace the battery successfully. I will order a new back, which does not cost a lot and should hopefully come with new adhesives as well.One thing to note though when reassembling the device:The main flex cable has the same connector on both sides and can therefore be plugged in incorrectly. I didn't pay close enough attention to the orientation and after reassembling, the phone didn't turn on, as something seemed to short out. Fortunately nothing got damaged, but be careful to connect the cable the right way round.The flex cable has printed markings "MB" and "SUB". Connect the side marked with "MB" to the Motherboard on top of the phone and the side marked with "SUB" to the daughterboard below with the charging circuitry.
