🛠️ Step-by-Step Guide — Infinix Hot 30i Back Cover Disassembly

1. Required Tools

Prepare the following tools before starting:

Heat gun or screen heater
Suction cup
Plastic pry tools / opening cards
Thin plastic spudger
Optional: thin opening blade
Anti-static gloves

Avoid metal tools whenever possible to reduce the risk of internal damage.

2. Heating the Back Cover

Heat the rear cover for 1–2 minutes in circular motion:

Focus on the edges, not the center of the device
Avoid heating the camera module directly
The goal is to soften the adhesive, not to melt it

3. Creating the First Opening Gap

After heating:

Attach the suction cup at the lower part of the back cover
Pull gently to create a small gap
Insert a plastic card into the gap
Do NOT force the opening — the cover can easily crack

4. Sliding the Card Around the Frame

Move the plastic card gently around the entire frame:

Start from the bottom, then left side, then top
Avoid applying pressure on the right side where the fingerprint sensor flex cable is located
Reapply heat if the adhesive becomes hard again

5. Removing the Back Cover Completely

Once the adhesive is weakened:

Lift the cover slowly from the opposite side of the fingerprint sensor
Do not twist or bend the back cover excessively
Continue loosening the adhesive until the panel separates smoothly

6. Fingerprint Sensor Flex Cable Warning

Depending on the Hot 30i variant:

Some units have the fingerprint cable attached to the inner frame
Others have the cable close to the side button

Always inspect carefully before lifting:

Do not insert tools deeply near the power button area
Lift slowly to check for any attached cables

7. After Opening the Device

Once the back cover is removed:

Unscrew the inner plastic frame
Disconnect the battery before touching any component
You can now access the charging port, cameras, speaker, and motherboard for repair

🔒 Safety Precautions During Disassembly

Do not overheat the device (may damage the LCD)
Never insert hard tools near the battery
Avoid pulling the back cover quickly from the fingerprint side
Do not use strong solvents like acetone — they damage plastic
Always place the phone on a stable, non-slip surface
Disconnect the battery first before working on any internal part
