Disassembly steps
1) For disassembling you need the Nokia Standard toolkit version 2. You will also need the SIM door key,
the unibody opening frame SS-321, the RF cable disassembly/assembly tool SS-298 and the battery
release tool SS-317.
Note that the device used in this disassembly procedure is RM-940.
2) The power must be off during the disassembly procedure.

3) Protect the DISPLAY with protective film.
4) Release the SD TRAY with the SIM door key and pull the tray out.

5) Release the SIM TRAY with the SIM door key and pull the tray out.
6) Use tweezers to remove the IMEI LABEL. Store the IMEI LABEL on non-stick surface so it can be re-
assembled.

7) Unscrew the TORX+ size 2 LOCKING RAIL SCREW.
8) Use the unibody opening frame SS-321 to separate the DISPLAY ASSEMBLY and the UNIBODY
ASSEMBLY. First place the bottom end of the device into the frame.

9) Place the top end of the device into the frame.
10) Start releasing the DISPLAY by pressing the device upper end from back side. Press both sides so
that the top end of the DISPLAY lifts up from UNIBODY ASSEMBLY.

11) Remove the unibody opening frame SS-321 and continue separating the DISPLAY by moving the
UNIBODY ASSEMBLY carefully from side to side with hands.
12) The DISPLAY and the UNIBODY ASSEMBLY can now be separated.

13) Use the SS-93 to detach one corner of the SHOCK ADHESIVE and then peel it off with fingers. Do not
use it again. Discard it.
14) Use the SS-93 to detach one corner of the HEAT SPREADER then peel it off with fingers. Do not use
it again. Discard it.
Do not damage the battery surface. Be careful not to leave residues from HEAT SPREADER around the
battery connector as it may cause shortcircuit. If adhesive residues are left on MSM shield lid, remove
them with isopropyl alcohol.

15) Unscrew this TORX+ size 4 screw. Do not use it again. Discard it.
16) Detach the BRIDGE CONNECTOR SUPPORT with tweezers.
Be careful not to damage the connectors underneath or any nearby components.
