3G Flash Procedures
Introduction
This document is intended to describe the flashing (soft-
ware updates) and procedures for 3G terminals. The
3G terminal described in this document will be limited
to the A920/A925.
Software updates need to be handled in a controlled
manner. Carrier software approvals need to be consid-
ered before initializing a flashing procedure. Consult a
Motorola representative to ensure that the correct soft-
ware is programmed.
Software updates allows the service organization to re-
solve field software issues that customers may be ex-
periencing. Some issues may pertain to specific condi-
tions, therefore, not all units will contain identical soft-
ware versions.
Hardware Requirements
The following hardware will be required to properly
flash the phone.
Power Solution
1. Fully Charged battery (SNN5638A)
2. Full-rate Charger (PSM5049A)
Interface Solution
1. USB PST Tool Kit (S8951)
USB Cable (SKN6311A)
Security Key
Adapter kit
Power supply (SPN4059A)

Motorola Confidential Proprietary
Flash Procedures
1-2
PST Software
The Product Support Tool (PST) is used to allow func-
tions such as flashing, flexing, memory transfers, and
datalogging. Please contact your local Motorola ser-
vice representative to obtain user documentation for the
PST.
Insure that the Motorola service representative also pro-
vides installation documentation, security key require-
ments, and other related information.
Flash Software Access
Flash software can be accessed by Motorola person-
nel only. Contact your local Motorola service repre-
sentative to obtain updated software releases.
In some cases the software may be distributed in ZIP
format. The user will need to extract the original (.SHX)
file from the ZIPfile before is can be used with the PST.
WINZIP is the application that can be used to extract
the original flash file. For more information on WINZIP,
visit,
http://www.winzip.com
Phone Flashing
Before beginning any flashing procedure, always insure
that all hardware connections are secured. Refer to fig-
ure 1 for flash connection guides.Any intermittent hard-
ware connections may cause the procedure to fail and
result in a nonfunctional (Bricked) 3G terminal.
The A920/A925 contains a set of Flash EPROMs for
the Adjunct Processor and a separate set of Flash
EPROMs for the Baseband Processor. Due to this de-
sign, theA920/A925 will require separate Flash files
for each processor if a “Combo” file is not provided.
A “Combo” file contains the following files,
Adjunct Processor Flash
Baseband Processor Flash
Customer image flex
Power Solutions
There are two types of power solutions to perform a
flashing procedure.
1. Fully Charged Battery Solution
2. Full-Rate Charger Solution (recommended)
If the user decides on using the battery solution, he/she
must verify that the battery is fully charged. Failing to
verify the capacity of the battery may result in battery
depletion prior to completing the flash process. This
action may cause unrecoverable failures to the 3G ter-
minal.
Hardware Connection Solution
A920 flash procedures require a USB hardware con-
figuration. Refer to Figure 1 for details.

PST Flash Procedure
Use the listed procedure to complete the flash proce-
dure for a 3G terminal. The baseband processor needs
to be flashed first. Once the baseband processor flash
is successful, follow up with flashing the adjunct pro-
cessor.
1. Download the desired flash software into the
computer.
2. Launch the PST application by choosing Start/
Programs/Motorola PST/Flash & Test Com-
mands.
3. Attach battery and connect hardware as illus-
trated in figure 1.
4. Press the Power key and insure that the phone
is completely powered on.
5. In the PST application, click on the Browse
button and select the desired flash software
6. Select the device that will be flashed.
7. The 3G terminal will be placed inAdjunct flash
mode, select the device again to enable the Flash
button.
8. Click on the Flash button to begin flashing. DO
NOT interrupt any hardware connections dur-
ing the flash process. Connection interruptions
may cause the flashing process to fail and ren-
der the 3G terminal non-operational.
9. When flashing is complete, a message will pop
up stating,” Flash another phone?”. Select “No”
and waiting for 30 seconds before continuing.
10. Power up the 3G terminal to insure that the flash
procedure was successful.
11. On the first power up, the user will be prompted
to select a language and calibrate the touch
screen.

A920/A925 Special Procedures
There are some variables that need to be considered
when updating software for a A920/A925. Improper
update procedures may cause the 3G terminal to fail.
Always read the release notes for software releases prior
to updating the software on aA920/A925.
The user needs to insure that the adjunct and baseband
flash files are part of the same build.Also, the user needs
to be aware of any step-up procedures. This may re-
quire the user to flash an updated bootloader. Step-up
procedures can be found in the software release notes.
In order to successfully flash a A920, the following se-
quence is recommended.
1. Backup user data
2. Flash/upgrade the software
3. Perform a “Master Clear”
4. Restore user data
Flash Procedure Summary
The following is a summary of the procedures for flash-
ing a A920.
1. Launch PST.
2. Connect USB hardware. Insure 3G terminal
remains off.
3. Power up 3G terminal.
4. Use the Browse button to open the “Combo”
flash file.
5. Select the device for flashing.
6. Select the device again to enable Flash.
7. Click Flash.
8. Click Yes to all the prompts if the user is certain
that software being flashed is correct.
9. When flashing is completed, click “No” when

Entry Method
Once the test command mode is entered, two prompts
are used to collect command request information from
the user. The opcode entry prompt (Figure 5) allows
the entry of either an entire command as described in
this section, or entry of a partial command. If a partial
command is entered, the user will be prompted to enter
the remaining required information via an appropriate
number of field entry prompts (Figure 7). Selecting Test
with no data entered in the opcode or field entry screen
will cause a parse error (unless the field is optional).
The comma is used to delimit fields on the opcode en-
try prompt and is not allowed on the field entry prompt.
On the opcode entry prompt, it is not legal to have a
comma immediately follow another comma.
Opcode entry
The opcode entry prompt allows the user to enter the
opcode for the test command, or the opcode plus ad-
ditional parameters delimited by the “,” character.
The user may select Test after entering the opcode. If
the opcode requires further parameters, the list of Fields
shall be shown starting with 1. After all the fields are
entered the user shall select Test. The results are then
shown on the screen.
