why take out the battery??

Hi JPBrokenIT,

this is a guide for the full display assembly. This means you’ll exchange the display including the whole mid frame for a new one. If you’re going to leave the battery in its place. You need a new one for your spare part. If you don’t want to buy a new battery, you’ll need to transfer it from the old mid frame with display, to the new one. If you want to exchange the display without the mid frame, you need to follow this guide - Huawei Mate 9 Display Replacement

Hi guys, just a small Thing, but you missed to mention one additional screw which holds the Speaker unit on top of the “arm” to the left. Anyway, very good and helpful guide. Christian

Hi Chris V,

thanks for mentioning. I made the correction.

I was stuck at step 2. I could not pry open the case, not even a tiny gap, and the plastic opening tool broke. The assembly and case were attached so tight. I even tried to use a flat metal screw driver to try to get an “entering point”. But the case was so well snugged onto the assembly. Maybe Huawei put some glue during assembling process. I halted the repairing. At least the phone is now still functioning with a broken screen.
