Introduction
This article explains the firmware naming scheme used for the H200 series of Amino devices.
Understanding the naming convention helps ensure compatibility, traceability, and clarity.
Prerequisites
This article assumes you are working with Amino H200 media players and are familiar with the software deployment and support process.
Summary
Structure of a Firmware Name
The standard naming convention for H200 firmware releases follows this structure:
25.<AOSPVersion>.<YearYearQuarterPatch>.<BuildNumber>R
Example
25.6.2520.8R
This version string is made up of the following components:
-
25– Device identifier (H200 and H200W) -
6– AOSP version (e.g., Android 12) -
25– Year of release (2025) -
2– Quarter of release (Q2) -
0– Patch version -
8– Build number -
R– Release build
Detailed Explanation of Each Component
25 — Device Identifier
This prefix is fixed for all H200 and H200W firmware releases. It denotes the device family (H200 series).
6 — Android Version
This digit represents the Android operating system version used in the firmware:
-
3= Android 10 -
6= Android 12
This helps teams quickly identify the AOSP version of the firmware. The number is not sequential because we match it with the SoC SDK version.
25 — Release Year
A two-digit number indicating the year of the firmware release.
-
23= 2023 -
25= 2025
2 — Quarter
Represents the calendar quarter in which the firmware was released:
-
1= Q1 (January–March) -
2= Q2 (April–June) -
3= Q3 (July–September) -
4= Q4 (October–December)
0 — Patch Version
This value increases with each patch to a quarterly release:
-
0= Initial quarterly release -
1= First patch -
2= Second patch - and so on...
This allows for consistent version tracking for incremental updates.
8 — Build Number
A sequential internal build number generated by the CI/CD pipeline.
It is used to uniquely identify builds and correlate with internal testing and deployment logs.
R — Release
The letter "R" indicates this is a firmware signed with release keys, which indicates it is a firmware to be used for deployment. The lack of the "R" at the end of the firmware indicates the firmware is a debug version, with root access, and therefore, not allowed for deployment.
