The standard tool for flashing Amlogic chips is the Amlogic USB Burning Tool. This is a Windows-only application, so you will need a PC.
The Basic Process:
Conclusion Working with Amlogic S805 firmware demands caution: match firmware to hardware, always back up originals, and keep serial access for debugging and recovery. For hobbyists, small communities can help with custom images, but closed-source blobs limit full replacements. For device recovery, the USB Burning Tool plus UART diagnostics are the most reliable path to restoring functionality.

Finding firmware for Amlogic S805 devices (like the MXQ or OTT TV boxes) typically involves either using "Stock" (factory) files or "Custom" ROMs to breathe new life into these older chipsets. Since the S805 is legacy hardware, official updates from manufacturers are rare. 1. Official/Stock Firmware
If you need to restore your device to its original state, you must match the firmware to your specific hardware variant (e.g., WiFi chip model).
MXQ S805 Stock Firmware: Often available for versions with Broadcom AP6181 (no Bluetooth) or AP6210 (with Bluetooth). Update Method (Toothpick Method):
Download the ZIP/RAR firmware and unzip it to the root of a FAT32-formatted Micro SD card.
Insert the card, press and hold the reset button inside the AV port with a toothpick, and power the device on. Release the button when the update screen appears. 2. Custom ROMs (Recommended for Performance)
Because the S805 uses an older 32-bit architecture (ARMv7), newer Android apps often struggle. Enthusiasts often switch to lightweight Linux-based OSs:
LibreELEC / CoreELEC: Optimized specifically for media playback (Kodi). These are much faster than stock Android on this hardware.
Custom Android Builds: Community-developed versions (like Android 7.1/9) can sometimes be found on forums, though they may have bugs with WiFi or remote drivers. 3. Warning & Risks
Verify Model Compatibility: Flashing firmware meant for a different S805 box can "brick" your device (render it unbootable).
Backup: Always try to back up your current firmware before flashing a new one if possible.
Sources: Reliable places to look for specific files include XDA Developers, FreakTab, or the official LibreELEC forums. Amlogic S805 Firmware Download - Google Groups
The Amlogic S805 is a legacy quad-core Cortex-A5 processor designed for entry-level Android media players, supporting 1080p hardware video decoding. Over its lifespan, its firmware ecosystem has evolved from official Android builds to diverse community-driven open-source operating systems that extend the hardware's utility. Armbian Community Forums 1. Official Stock Firmware
Factory firmware for S805 devices typically centers on legacy Android versions and specific media capabilities: Operating Systems
: Most original S805 devices (like the MXQ S85 or MXV) shipped with Android 4.4.2 KitKat . Experimental updates were occasionally released for Android 5.1.1 Lollipop Key Features amlogic s805 firmware
: Stock firmware includes drivers for specific Wi-Fi modules (e.g., Broadcom AP6181 or AP6210) and supports DLNA/Airplay. Update Method
: Most S805 devices use the "toothpick method," where a reset button hidden inside the AV port is held while powering on to enter recovery mode. 2. Community-Driven Alternatives
As official support waned, community developers created "Just Enough OS" (JEOS) alternatives that focus on media center performance rather than a full Android experience:
Amlogic S805 is a legacy quad-core ARM Cortex-A5 processor designed for low-cost Android TV boxes and media players. While it is now considered an entry-level SoC (System on a Chip), its firmware ecosystem remains active due to its popularity in the "retro-gaming" and "home media server" hobbyist communities.
This paper explores the firmware architecture of the Amlogic S805 chipset, focusing on the transition from stock Android-based software to community-driven Linux distributions. It examines the bootloader environment, kernel limitations, and the role of third-party firmware in extending the lifecycle of S805-based devices. 1. Hardware Architecture Overview
To understand the firmware, one must first identify the hardware constraints: Quad-core ARM Cortex-A5 (up to 1.5GHz). Quad-core Mali-450. Hardware decoding for H.265/HEVC at 1080p (60fps). Typically paired with 1GB DDR3 RAM. 2. Firmware Components
Amlogic firmware is generally composed of three primary layers: Bootloader (U-Boot):
The first stage of software execution. In Amlogic devices, this is often "locked" or "signed," making it difficult to install custom OSs without specific exploits or "burning tools." Most S805 devices run on the Linux 3.10.x kernel
. This legacy kernel is a major bottleneck, as modern hardware acceleration drivers are difficult to backport. Android Layer:
Stock firmware usually ships with Android 4.4 (KitKat) or 5.1 (Lollipop), utilizing the Amlogic SDK. 3. Custom Firmware Ecosystem
Because official support from manufacturers has largely ceased, the S805 survives through community firmware: LibreELEC / CoreELEC:
These are "Just enough OS" distributions for Kodi. They bypass the heavy Android UI to provide a fluid 1080p media experience. Lakka / EmuELEC:
Firmware specifically tuned for retro-gaming, turning the S805 into a dedicated console for systems like NES, SNES, and PlayStation 1.
A lightweight Debian/Ubuntu-based distribution used to turn these boxes into low-power Linux servers (e.g., for Pi-hole or MQTT brokers). 4. Installation & Recovery Procedures
Firmware deployment on the S805 typically involves two methods: Amlogic USB Burning Tool: A Windows-based utility used to flash files via a male-to-male USB cable. SD Card Boot (The "Toothpick Method"):
Pressing a hidden reset button inside the AV jack while powering on to force the device to boot from an external microSD card. 5. Challenges and Limitations Thermal Throttling:
Many S805 boxes have poor heatsinks; custom firmware often includes aggressive undervolting to prevent crashes. DRM Issues:
Custom firmware usually lacks Widevine L1 certification, meaning streaming apps like Netflix are limited to 480p resolution. Wi-Fi Drivers:
Most S805 devices use cheap, proprietary Wi-Fi chips (like Realtek or Broadcom variants) that often lack open-source drivers in standard Linux kernels. Conclusion A: Never
The Amlogic S805 firmware landscape has shifted from a consumer Android media platform to a versatile playground for hobbyists. Despite the aging 32-bit architecture and legacy kernel, optimized distributions like LibreELEC allow these devices to remain functional as dedicated media players or light-duty servers well beyond their intended shelf life. specific Linux kernel optimizations for this chip?
The Amlogic S805 is a legacy 32-bit quad-core processor commonly found in older Android TV boxes like the MXQ S85 and M201. While official Android updates for these devices typically capped at version 4.4.2, various community-driven firmware projects provide more modern capabilities, such as running the latest Kodi or lightweight Linux distributions. Recommended Custom Firmware Projects
If you are looking for "good" options to repurpose or update an S805 device, these projects are highly regarded in the community:
LibreELEC (Kodi-focused): Best for turning the box into a dedicated media center.
Latest Stable: Legacy v9.2 LTS builds (Kodi 18.9) are actively maintained for S805 devices.
Features: Includes experimental driver support for various Wi-Fi chips (e.g., RTL8723AS) and optimizations for the S805's limited 512MB–1GB RAM.
Resource: Check the LibreELEC S805 Forum for specific images.
Armbian (Linux-focused): Ideal for using the device as a low-power server (e.g., Pi-hole, file server).

Here’s a short, engaging story built around the Amlogic S805 and its firmware ecosystem.
Title: The Ghost in the Dongle
In the dusty back room of "Pixel Perfect Repairs," old tech went to die. But for Mira, a 19-year-old firmware hobbyist, it was a playground. Her latest patient was a forgotten TV box—a no-name brick powered by an Amlogic S805. The label was worn off, the remote was lost, and the owner just wanted his photos recovered.
The box wouldn't boot. It just blinked a single, angry red LED.
Standard tools failed. The usual Amlogic USB Burning Tool refused to recognize the device. The short-pin trick on the NAND chip? Nothing. Desperate, Mira dug into the S805's secret heart: the BootROM. Using a logic analyzer, she found a UART debug header hidden under a blob of glue.
She connected her laptop, fired up screen /dev/ttyUSB0 115200, and saw the truth. | Error | Meaning | Fix | |
The bootloader wasn't corrupted. It was fighting back.
Garbled text scrolled by, then a clear message: [BL31]: trng: initializing... error. Trust zone violated. Fallback to legacy mode?
Someone—likely a cheap overseas factory—had flashed a hybrid firmware. It was a Frankenstein's monster: an Android TV kernel stitched onto a Linux OpenELEC (Kodi) rootfs, held together with duct tape and bad checksums. Every time the system tried to mount the system partition, the S805's Mali-450 GPU would throw a page fault, crashing the watchdog timer.
But then Mira noticed something odd. The crash dump contained readable ASCII—scraps of an old developer's diary.
"Day 34: The S805 has no hardware virtualization, but if I remap the IRQ table... I can hide a tiny microkernel in the video decoder's reserved memory. Nobody ever scans the video buffer. It's the perfect steganographic firmware vault."
Her heart raced. The "broken" box wasn't broken. It was possessed by an abandoned project—a secure enclave running parallel to the main OS, unknown to Android, unknown to the bootloader. The crash wasn't a bug; it was a decoy.
Carefully, Mira crafted a custom u-boot script for the S805. She bypassed the normal boot flow, halted the bootloader right after DDR init, and injected a tiny payload over Amlogic's proprietary USB protocol (the one undocumented in the public datasheets).
The terminal blinked.
[SECURE] Welcome back, architect. System integrity: 97%
Then, the box's LED turned green. The forgotten photos appeared on the screen—but so did something else: a hidden partition labeled Project_Chimera. Inside were design files for a mesh network radio, using the S805's I2S audio bus as a spread-spectrum transmitter.
The owner never got his photos. But Mira got a story—and the key to a ghost in the machine that no firmware update could ever erase.
Moral of the story: Never trust a cheap TV box. Its firmware might be hiding more than just bad drivers.
Here’s a structured feature set for an Amlogic S805 firmware (ideal for a custom ROM like LibreELEC, Armbian, or Android TV).
In the fast-paced world of technology, devices are often deemed "obsolete" within a few years. However, for the tinkerers and DIY tech enthusiasts, there is a certain charm in breathing new life into older hardware. If you have an aging Android TV box, a legacy Mini PC, or an old tablet gathering dust, there is a high chance it runs on the Amlogic S805 chipset.
While the S805 is a veteran in the chipset world, a custom firmware flash can transform it from a sluggish paperweight into a surprisingly capable media player.
In this post, we dive deep into the world of Amlogic S805 firmware—where to find it, how to flash it, and whether it is worth the effort in 2024.
If the USB Burning Tool does not recognize your device, you have a mask ROM mode brick. Do not panic.
Introduction
The Amlogic S805 is a legendary system-on-chip (SoC) found in countless low-cost Android TV boxes, single-board computers (like the Odroid-C1+), and even some IoT devices from the mid-2010s. While it’s no longer a performance champion, millions of these devices are still in active use for basic streaming, Kodi, and retro gaming.
However, the biggest pain point for S805 owners is firmware—finding the correct ROM, recovering a bricked device, or upgrading to a newer version of Android (typically 4.4.2 to 5.1.1, or even LibreELEC/Linux).
