Dx80.ce8.2.0-syn213b.rel.pkg =link= May 2026

Operating System Conversion: This package is essential for users who want to revert their DX80 from the newer Cisco CE (TelePresence) software back to Android to regain access to local apps, web browsers, and Google Play services.

The "Synergy" Transition: The "syn" in the filename stands for Synergy, representing the transition phase between the two different software stacks. Why People Search for It

This file is highly sought after in the Cisco community because it has been deferred (removed from public download) by Cisco due to security vulnerabilities and lack of support for the aging Android 4.1 platform. Users often look for it to:

Prevent E-Waste: Repurpose older hardware that is no longer supported on modern Webex cloud versions.

Specific App Requirements: Use the DX80 for third-party Android applications that are not supported on CE software. Key Technical Prerequisites

To use this file successfully, the device generally must follow a specific upgrade path:

Intermediate Version: The DX80 must usually be running a version of CE 8.2.x (like CE 8.2.1 or 8.2.2) before applying the conversion package.

Configuration File: In many Cisco Unified Communications Manager (CUCM) environments, a corresponding .cop.sgn file (typically cmterm-ce820-synergy213b.cop.sgn) is also required for the transition. Important Considerations

Security Risk: Cisco deferred this release due to critical vulnerabilities (such as CVE-2020-3143). Returning to Android software leaves the device unpatched against modern threats.

Availability: Because it is deferred, it is no longer on the Cisco Software Download page. Most users now rely on community archives or contacting Cisco TAC with a valid service contract. DX80 downgrade from CE to Android: Help ! - Cisco Community

The file dx80.ce8.2.0-syn213b.rel.pkg is a specialized firmware package used to convert a Cisco DX80 video conferencing unit from Collaboration Endpoint (CE) software back to its original Android-based operating system. Overview of the Software Package Historically, the Cisco DX80

shipped with an Android-based OS. In late 2016, Cisco transitioned the device to the CE software platform to align it with their other TelePresence products, such as the SX and MX series. While CE offered improved stability and a more video-centric interface, some users preferred the Android OS for its ability to run third-party applications and provide local web browsing.
