Creating Sig files on brew

SIG files

SIG files are device-specific signature files that are required for each device you are using for your application development. These files must be obtained from QUALCOMM and are good for 90 days. After 90 days, the signature file expires and QUALCOMM must issue a new signature file.

Only one SIG file is required per device. However, because each individual application requires its own corresponding SIG file, you make a copy of the original SIG file and rename it to match the name of the application you have created. Remember that the SIG file must reside in the same folder as the MOD file, the application file for the BREW device.

You must be an authenticated BREW developer to access the signature generation utility on the BREW website.

NOTE

SIG files are required for testing applications on devices, but they are not required for testing using the BREW Simulator.

To obtain a SIG file:

1. Go to the BREW website and navigate to the page that contains the link to the QUALCOMM web-based test signature generator.
2. Select BREW Testing Generator.
3. Enter your BREW developer user name and password.
4. In the ESN field, type 0x where the ESN number is the number you find under the device battery when you lift it up.
5. Click Generate and wait for the Download Signature link to appear.
6. Download the signature and save the file; it will be required for all testing on the device.
