Huawei Honor 8 Motherboard Replacement

Introduction

This guide details how to remove the motherboard from the frame.

What you need

Step 1 Rear Glass & Frame

Make sure you spend at least 5 minutes heating up the adhesive. Prying off the glass cover too early can result in cracking the panel.
Using a heat gun or hairdryer, apply heat approximately three inches above the glass panel to warm up the adhesive around the outside edge of the phone.
Make sure to apply heat evenly across the outside edge of the device.

When I reverse the order to close the back side, would it hold with the old adhesive? if not, how do I keep it from falling?

Step 2

Be careful not to tear the orange ribbon wire when removing the back panel.
Using a plastic opening tool, gently pry up a corner of the rear glass panel.
Slowly slide the plastic opening tool around the outside of the glass panel to break through the adhesive.
Additional plastic opening tools can be used to help separate the back panel from the phone body.
Gently lift the back panel off once all the adhesive has been removed.

Step 3

Using a Phillips PH00 screwdriver, remove the silver Phillips 3.5 mm screw circled in red.
Using a spudger, gently lift off the small metal tab that was held in place by the screw.
Gently pry off the orange ribbon wire on the back panel.

Step 4

Keep the tiny screws on a magnetic pad or a designated area so they will not be lost. There are eighteen screws in total.
Using a Phillips PH00 screwdriver, remove the eight silver Phillips 3.5 mm screws circled in red.
Using a Phillips PH00 screwdriver, remove the six black Phillips 4.0 mm screws circled in orange.
Using a Phillips PH00 screwdriver, remove the single silver 3.0 mm Phillips screw circled in yellow.
Using the Phillips PH00 screwdriver tip, gently scratch away the white stickers outlined in green circles to expose hidden screws.
Using a Phillips PH00 screwdriver, remove the two black Phillips 4.0 mm screws circled in green.

Edit

On my phone, the white sticker was in the bottom right corner, rather than the middle right side. However, the screw types were all the same as listed in the step above, so proceeding to remove the sticker and screws worked fine.

one of my green screws and orange screws were reversed from image, but all worked out fine, as well.

Lacking a useful magnetic pad, I made a pad of (sticky side up) masking tape to hold screws which I could mark up and it worked quite well.

Wenn man tatsächlich nur die Hauptkamera tauschen will, sind die Schritte 6 - 13 meines Erachtens überflüssig. Sobald der innere Rahmen abgenommen ist, kann man die Kamera von der Hauptplatine lösen (= Schritt 14).

Was ist das genau für eine Antenne? Habe sie eben aus Versehn abgerissen und trotzdem einfach zugeschraubt und sämtliche Funktionen (WLAN, Mobile Daten, GPS) sind noch in Takt.

Bei mir ist es so wie bei Ferdinand (Anschluss hat sich vom Board gelöst, dennoch scheint noch alles intakt zu sein. ). Ich würde behaupten, dass es extrem wahrscheinlich ist den Anschluss beim entfernen dieses Kabels abzureißen, deshalb würde ich empfehlen, den Schritt entweder auszulassen oder das Kabel am anderen Ende zu entfernen (dort sieht der Anschluss stabiler aus). Wenn man den Schritt überspringt, muss man natürlich noch vorsichtiger bei der Entfernung des Akkus sein.
