DISASSEMBLY
•Remove the SIM Card Holder (1).
•Remove the Antenna (2) using the Antenna Jig; also remove the Antenna Ring (3) which is pressed over the
top/bottom cosmetic part. Note the position (top/down side) of this ring for correct reassembly.
•Remove the Battery Lid (4) and the Battery (5).
•Unscrew four screws (a) on the Battery Compartment.
•The Lower Case Assy (6) can now be lifted; however, it is still tightened as the top side is held together with
claws.
•Lifting the Lower Case Assy is preferrably performed gently on the antenna side. When reassembling this
part, first insert the REC/PLAY button side.
•The RF/Logic Board (7) along with the Microphone Arm Assy (8) can now be taken out. Note, however, that
the RF/Logic Board is still held onto the Display Board through a connector located at the bottom/left side
between the two boards, so at this point still invisible.
•To remove the RF/Logic Assy (7), including the Microphone Arm Assy (8), first of all put the Microphone Assy
to an angle of 90° versus the set. Next, push the Microphone Assy gently upward while at the same time
pushing the Microphone Holding Part of the Upper Housing Assy downward (b). This should release the
RF/Logic Assy from the rest of the set.
•The Microphone Arm Assy can be released by unscrewing one screw (d).
•When reassembling this board, gently push in the bottom/left corner to insert the RF/Logic side connector
into the display connector side.
•When disassembling the RF/Logic Board, three Plastic Sleeves (10) will come loose; note their position for
correct reassembly.
•The Display Board (11) can now be taken out of the Upper Housing Assy (12).
•The Jog Mounted PCB (13) can be taken out of the Lower Case Assy after unscrewing four screws (c). Note
that one of these screws has a large head.
•Underneath the Jog there is a Jog Shielding (14).
IMPORTANT NOTES :
1) Disassembly of the RF/Logic Assembly, including the Lower Shield (on which the
IMEI sticker is mounted) and all other shielded elements is totally forbidden. Any
attempt to do so may lead to non-compliance with GSM as well as CE
specifications, and in extreme cases it can cause interference problems.
2) When replacing cosmetic parts, verify if all spacers are mounted on the new
cosmetic; if necessary transplant them from the old to the new cosmetic part.
3) When reassembling, make sure all screws are tightened fully.

SECTION 4
PROGRAMMING INSTRUCTIONS
1. Setup
The programming jig is based upon a PC-linked application.
Minimum requirement for PC is IBM compatible, 386 type.
The software is a basic MS−DOS application.
Please do NOT run it as a DOS mode application starting from a
Windows program. It is necessary to exit Windows when starting the PC-link application, or preferrably to start
the PC without entering Windows.
Thejigconsists of: Level Convertor, Connection Cables(PCtoLevelConvertorandLevelConvertorto CMD−Z1)
and application software on floppy disc.
No specific software installation is needed; only copy all the files from the floppy disc to the PC, ideally into a
dedicated directory.
Starting of the software updating program will take place when going to the directory where you have loaded
the application program and typing CMD−Z1 + enter.
2. Important notes
•Before connecting the CMD−Z1 to the level convertor, take out the battery of the CMD−Z1; the CMD−Z1
must be powered from the level convertor.
•Whenever the program isin progress, orwhen the levelconvertoris powered on,never disconnect orconnect
any cables.
•Never interrupt the power supply to the level convertor whenever a software update is in progress.
•The level convertor has some switches; please make sure they are in the correct position. These switches
are included also to allow future changes, or other applications.
3. Menu screens
The program will show the following masks according to the respective menu points.
At the first menu point, the following mask is displayed:
Program-CMD-Z1 Service Station Utility
Version: X.XX for PC (DOS)
Mode: Update AP/OS code and change the Language set
(C) Copyright XXXX, XXXX Sony Corporation. All rights reserved
Current Status
Serial Port: COM 1, 19200, N81
1. Update.
2. Serial Port Setting
Please make choice (1/2) = 1
The user can either choose the serial port or go for the updating option immediately.
The default setting for the serial port is COM1.
NOTE If a port were chosen which is not connected to the Level Shifter, the error message “No Response”
would be displayed after starting the update process.
8

If option 1 has been chosen, the following display will appear:
Flash ROM Type – Sharp 30 23
Set the switch of the voltage convertor as follows.
Vpp = on; FROMRP = off
After you set the switch, type any key to proceed.
The user is requested to set the switches on the Level Shifter to the settings displayed.
To enable the ROM Loader Software to determine the ROM manufacturer and hence the switch settings, the
ROM−ID is read first from the Z1. The settings shown in the sample above are only valid for a Sharp ROM and
are therefore only an example. Future ROM types may come from a different manufacturer. After setting the
switches on the Level Shifter, press any key to proceed.
NOTE If the connection has been set up successfully, the green lamp on the Z1 display starts flashing.
As soon as the connection is established successfully, the current AP and OS software versions are displayed
as well as the latest versions to ensure that the serviceoperator is fully aware oft he differences of both software
versions.
Proceeding the program leads to the following simple options from which the operator is requested to choose:
– Update AP? (y/n/c) or
– Update OS? (y/n/c) or
– Change Language Set? (y/n/c)*
The operator does not have to change the Language Set or any other item he does not want to change at this
time. Thus it is possible to change the operating system (OS) only while the application code (AP) and the
Language Set remain unchanged.
NOTE Typing in “c” (cancel) will interrupt the updating process at any time and will abandon the program.
*The request to update AP(y) makes a language set change necessary.
Therefore the message : “Default new language setting because of AP code change”, appears instead
of “change language set” (y/n/c)
9

General information
•No GSM test mode is implemented in the Z1 for use with the ROM Loader Software. For the software or the
Language Set update simply connect the Z1 with the Level Shifter and run the ROM Loader Software
(CMD−Z1.EXE). The Z1 does not have to be switched on!
•The switch settings of the Level Shifter are as follows:
Switch Intel ROM Sharp ROM
Main power always on always on
Vpp off on
IGN/Vpp always on always on
FROMRP disabled (factory set to off position) disabled (factory set to off position)
GSM power always on always on
Troubleshooting
•Cause 1
– The error message “ERROR : SIO Receive timeout” appears after starting the program and trying to
set up the connection between PC and Z1.
•Remedy 1
– Check the connection between MT (mobile terminal), Level Shifter, and PC. Also make sure that the
Level Shifter’s power is switched on (both switches). Both the Main Power LED and the GSM Power
LED must light up.
– Check whether COM1 or COM2 is active.
