- SIM Eject & Battery Cover Removal
Use the SIM eject tool to press into the small hole next to the SIM tray—this will pop the tray out just enough for you to remove it by hand. Set the tray aside safely.
Next, warm up the battery cover, focusing on the edges. Use a heat gun on a low setting or a hairdryer on medium until the cover feels warm to the touch.
Use the blade tool to carefully create a small gap at the bottom of the phone. Once there's enough space, insert the card tool and begin working it counter-clockwise around the device. Be sure to insert the card no deeper than 1–2 cm.
Take extra care on the left-hand side near the volume buttons—there's a flex cable here that can be easily damaged if the card goes too deep. Reapply heat as needed to soften the adhesive.
Once you've worked around the entire edge and broken the seal, gently wriggle the back cover off. This will release any remaining adhesive, particularly around the camera area.
- Chassis Removal
Remove the screws securing the internal frame—there are 9 at the top and 7 at the bottom. Once removed, double-check to ensure none have been missed.
Using a solid pry tool, begin separating the chassis from the screen. The easiest entry point is next to the empty SIM card slot. Insert the tool to create a small gap, then work your way around the entire edge of the phone. No adhesive is used here, so the frame should unclip with gentle pressure.
Once the frame is free, place the phone face down and slowly lift the frame. Be careful—there’s a flex cable connecting it to the motherboard. Gently lift just enough to see the connector, then use a probe tool to disconnect it, as shown in the video. Once released, set the frame aside.
Next, remove the black shielding lightly bonded to the battery. Slide a card tool underneath and work it back and forth to loosen the adhesive. Peel the shield away, then locate the battery connector on the far-right side and disconnect it.
- Finger Sensor Removal & Replacement
This step may look tricky, but it’s actually quite straightforward. Use a probe tool to unlatch the right side of the button—it should lift out easily. Repeat the process on the left side, and the button will pop out. You may also accidentally release part of the volume button assembly—don’t worry, that’s not an issue.
To install the new button, start by positioning the right side first. Use the probe tool to guide and press it back into place. Once it's secure, check the volume button retainer—if it was dislodged, simply press it back into position.
- Main Frame Installation
Reconnect the battery, then loosely position the internal frame back on top of the phone. Reconnect the flex cable for the fingerprint sensor, ensuring it's securely attached.
Once connected, press the frame gently into place, applying light pressure around the edges—you should hear it click as it locks in.
When you're satisfied with the fit, secure the frame with all screws: 9 at the top and 7 at the bottom.
- Battery Cover Installation
Before installing the battery cover, it’s essential to thoroughly clean all old adhesive from the phone’s frame. Use a plastic probe tool (avoid metal to prevent damage) to carefully scrape away the adhesive. This can take a bit of time—light residue or surface marks are fine, but any lumps or clumps must be fully removed. Repeat this process on the battery cover. Once clean, apply gentle pressure to remove the flash diffuser, then clean off any remaining adhesive underneath.
With both surfaces clean, install the square foam adhesive and the three adhesive strips onto the phone’s chassis as shown in the video. If any adhesive remains, be sure it’s completely removed. Peel off all protective covers from the new adhesive, preparing the phone for the battery cover installation.
Next, install the main adhesive onto the battery cover. Remove it from its protective backing and loosely align it, starting from the top. If the alignment isn’t perfect on the first try, don’t worry—it can be lifted and repositioned, as demonstrated in the video. Once properly aligned, press the adhesive down firmly to bond it to the battery cover.
Now, remove the protective film from the main adhesive. You’re ready to install the battery cover—align it using the camera lenses as a guide, then press it firmly into place. Apply gentle, even pressure across all adhesive areas to ensure a strong, lasting bond.
