Sony Nw-a105 | Custom Firmware
It is important to clarify that Walkman One is not "Custom Firmware" in the traditional sense; it is a modified version of the stock firmware.
The primary hurdle preventing CFW on the NW-A105 is the locked bootloader. Sony has a history of being relatively developer-friendly with their Xperia smartphone line, often providing bootloader unlocking tools. However, the Walkman division operates differently.
Created by a developer known as MrWalkman, this firmware mod takes the stock Sony operating system and optimizes it. Because it is based on the official Sony update, it does not require an unlocked bootloader in the same way a custom ROM would, making it significantly safer to install. sony nw-a105 custom firmware
For decades, the phrase “Custom Firmware” (CFW) has been the holy grail for digital audio enthusiasts. From the early days of Rockbox on iPods to the legendary customizations on the Sony PSP, tech-savvy users have always sought to break the chains of manufacturer limitations. When Sony released the NW-A105—a modern Walkman running a stripped-down version of Android—the community immediately began asking the same question:
If you are determined to modify your device, there is a middle ground. While you cannot install a completely new operating system, you can radically change the user interface and performance of the NW-A105 by installing the firmware. It is important to clarify that Walkman One
Unlike the NW-A55 , which uses a proprietary Linux-based OS, the NW-A105 runs on Android 9.0. This means you cannot simply flash a different operating system. Instead, the community focuses on to strip away Google Play Services and other non-essential components. Popular Optimization Methods
Most CFW for the A105 includes pre-rooted kernels (Magisk). This allows for advanced tools like ViPER4Android for system-wide EQ and Kernel Adiutor to underclock the CPU to save battery. However, the Walkman division operates differently

The Sony NW-A105 is a beloved digital audio player (DAP) that combines modern Android versatility with Sony’s legendary audio engineering. However, its Android 9.0 foundation often leads to concerns about battery life and system "bloat". While true "custom firmware" (like the non-Android builds for the NW-A55) does not exist for the A105 due to its complex Android OS, users can achieve similar performance boosts through advanced system debloating and software mods . Why Mod the NW-A105?
Before we look at the custom solutions, we must diagnose the patient. The NW-A105 runs on an aging Qualcomm Snapdragon Wear 2500 chipset (a chip designed for smartwatches, not music players). In stock form, the device suffers from:
The stock experience is sluggish. The battery life is famously poor (often cited as 8–10 hours, but in reality, often less). Sony’s proprietary Music app, while clean, lacks the customization of universal players like USB Audio Player Pro (UAPP). And perhaps most frustratingly, the device is cluttered with Google Mobile Services (GMS) and Sony bloatware that drain resources.
