A software upgrade is now available for the AT&T Adrenaline. This upgrade allows you to use the Adrenaline at faster LTE speeds* when available as we begin to deploy LTE in select markets.
Taking advantage of this software upgrade is simple. Just connect to the internet through AT&T Connection Manager (ACM) or AT&T Global Network Client (AGN) with the Adrenaline device to download the software upgrade. We recommend that you download the software via a Wi-Fi connection as standard data usage charges will apply if the software (approximately 45 MB) is downloaded over the wireless network.

Please note you must have the latest ACM version 220.127.116.11 or later, or AGN version 8.7.2 to complete the process.
*Limited 4G LTE availability in select markets. Adrenaline defaults to AT&T’s 3G network when not in a 4G LTE coverage area. 3G not available everywhere. LTE is a trademark of ETSI. Learn more at att.com/network.
