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 ZIP file 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,

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, the A920/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

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.
