Dx80.ce8.2.0-syn213b.rel.pkg [better]

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

First, you need to downgrade your DX80 from CE9. x to CE8. 2. x. The software, unfortunately, while still be visible on cisco.com' Cisco Community DX80 going from CE to android - Gawd not this crap again!

It is important to clarify from the outset: dx80.ce8.2.0-syn213b.rel.pkg is not a standard public software package, a mainstream Linux kernel module, or a recognizable open-source library.

Based on its naming structure, file extension, and internal syntax, this appears to be a proprietary firmware or system package—likely intended for an embedded device, a specific hardware controller, or a telecommunications component. dx80.ce8.2.0-syn213b.rel.pkg

If you arrived here searching for this exact string, you are probably an engineer, a systems integrator, or a technician troubleshooting a piece of enterprise hardware. This article will break down every component of the filename, explain its probable origin, discuss where you might encounter it, and provide practical guidance on handling such a package.

Step 5 – Safe Extraction (Read-Only)

If you need to inspect contents without installing:

# On Linux/macOS:
file dx80.ce8.2.0-syn213b.rel.pkg
# It might be an ar archive, cpio, xz, or proprietary binary.

Step 2 – Check File Integrity


Before attempting installation:


    

  • Look for accompanying checksums (.md5, .sha256, or .sig).
    • 

  • Compare file hash against vendor documentation.
    • 

  • Verify digital signature if possible (using openssl or vendor tools).
    • 



Part 8: Final Assessment & Recommendation


| Attribute | Value |
|-----------|-------|
| Confidence level | High – proprietary embedded firmware |
| Open source? | No |
| Safe to run without docs? | No |
| Typical user | Maintenance engineer, field tech |
| Likely industry | Broadcast, telecom, industrial control |
| Risk of bricking | High if mismatched |


Problem: “syn213b missing dependency”


    

  • Cause: The synchronization build requires a base ce8.2.0 image already installed.
    • 

  • Fix: Install base release first, then apply syn213b as an incremental patch.
    • 





1. Deconstruction of the Filename


Based on standard naming conventions in industrial electronics and VoIP hardware:


    

  • dx80: This is almost certainly the Poly (formerly Plantronics, formerly Polycom) SoundPoint IP VVX 1500 or a similar VVX series phone, which often used "DX80" in internal firmware designations. Alternatively, it could refer to a Fanuc industrial robot controller (DX100/DX200 series often have similar update syntax) or a specific Dahua surveillance product.
    • 

  • ce8: This typically refers to the Operating System version. In the context of Poly phones, this stands for "Communications Edition 8" (based on Android).
    • 

  • syn213b: This is likely a build number or a specific hardware revision code.
    • 

  • .pkg: This is a standard extension for a package file, used to install software or firmware.
    • 



Feature: Secure Over-the-Air (OTA) Delta Updates


Description:
This package introduces a Secure Delta Update Mechanism to the device firmware. Instead of replacing the entire operating system image, this feature allows the dx80 device to download and apply only the binary differences (deltas) between the current version and the new syn213b release.


Key Functionalities:


    

  1. 

    Bandwidth Efficiency:
    

      

    • Significantly reduces the file size of update packages (often by 60-70%) by downloading only the changed binary segments rather than the full .pkg image. This is critical for devices operating on restricted WAN or cellular networks.
      • 

    

    2. 

  2. 

    Integrity Verification:
    

      

    • Implements SHA-256 cryptographic hashing for the delta payload. Before any flash memory is written, the system validates the signature of the syn213b delta against the secure boot keys, ensuring that the package has not been tampered with and preventing "bricking" due to corrupted downloads.
      • 

    

    3. 

  3. 

    Atomic Rollback Capability:
    

      

    • Utilizes an A/B partitioning scheme. The update is applied to the inactive partition while the active system remains running. If the post-update verification fails, the bootloader will automatically revert to the previous stable version (pre-syn213b), ensuring maximum device uptime.
      • 

    

    4. 



User/Admin Benefit:
Administrators can deploy updates to remote fleets faster and with higher reliability, minimizing network congestion and eliminating the risk of device failure during the flashing process.


The file dx80.ce8.2.0-syn213b.rel.pkg is a software package specifically used for converting the Cisco DX80 desktop collaboration device from Collaboration Endpoint (CE) software back to the Android-based software. Key Purpose & Context Operating System Conversion : This package is essential


Synergy Conversion: This "syn" (Synergy) package is a specialized bridge software. It is primarily used when an administrator wants to revert a device running CE8 software back to the Cisco Android experience.


Critical Bug Fix: This specific version (213B) contains a fix for CSCve12723, a bug that previously caused some DX80 units to fail or "brick" during the conversion process from CE to Android.


Version Status: It is functionally identical to version 213, but the 213B update ensures the conversion logic itself is safe to use. Implementation Guide


To use this package, you generally follow the Cisco DX600 Series Conversion Guide. Note these critical requirements:


Software Downgrade: If your DX80 is currently running a newer version (like CE9), you must first downgrade it to a CE8.2.x release before the conversion package can be applied.


Installation Path: The file is typically uploaded to the Cisco Unified Communications Manager (CUCM) TFTP server or applied via the device's web interface, depending on your deployment mode.


Default Credentials: If you need to access the web interface for the update, the default username is admin with no password (leave blank) unless previously configured. Common Maintenance Tasks


If you are performing this software change and encounter issues, you may need to perform a hardware reset:


Hard Reset (On Boot): Press and hold the Volume Up button while powering on. When the Mute button lights up red, release Volume Up and press Mute once to trigger the reset.


Usage Tip: After conversion, the DX80 can still be used as a secondary PC monitor by connecting an HDMI cable to the PC port and tapping the screen to switch views.


Are you planning to perform this conversion on a single device via the web interface, or are you deploying it across a fleet using Cisco Unified Communications Manager? Cisco TelePresence CE Software Release Notes (CE8)
