Step 5 Daughterboard interconnect cable

Is step above Really required? Any issues if skip straight to step 7

Hello LCW,

you can jump straight to Step 7 but you should definitely disconnect your battery when working on your phone. However you can achieve that by only removing the metal shield and keep the display and interconnect cable plugged in. It’s just a bit of a fumbling.

Hi. I replaced the battery, but Huawei Mate 8 still does not charge.

Is there a charging IC that I need to replace?

Is the charging IC on the charging board, or on the motherboard?

If it is on the motherboard, where is it, and is it possible to change?
