Today we present a guide to update, recover or unbrick with a firmware file our Android TV-Box with Soc Amlogic S802, S805, S812, S905, S905D, S905W, S905X, S912, S905X2, S905Y2 or S922X . We have four methods in this tutorial that we will use depending on the files that we have to update, the most extended method is using the amlogic usb burning tool.
- FIND A FIRMWARE: You can use the search of our web, if we do not have it published we don’t have it, ask to your shop
- NOTE: AndroidPCtv is not responsible for problems that may cause a firmware change. If your TV-Box works well, do not change.

SELECT UPDATE METHOD
- Method 1 = I have a single file with .img extension and I want to make it easy (you need a PC)
- Method 2 = I have several files .img, .aml, .bin or a zip file (without PC)
- Method 3 = I have several files and the “ ” (deep recovery system)
! ATTENTION !
- If the TV Box works well for our needs DO NOT UPDATE
- If we don’t know what we are doing DO NOT UPDATE
- If our TV-Box don’t work and does’t have reset button DO NOT TRY TO UPDATE , claim to the store.
- There are many TV-Boxes especially the cheap ones that are copies called ” clones ” that are incompatible with the official roms of the original models and can leave useless our TV Box or do not work the WIFI. It is impossible to know if we have a clone or not without opening the device and comparing it with another original. We recommend buying devices in the stores we recommend and if possible only known models from trusted brands.
- If you do not find firmware for your model you may not have any brand support.
FLASH FIRMWARE WITH IMG FILE
There are two options for this method, in both cases the content of the TV-Box will be completely erased
- Method 1-A = From a PC we will create a special SD card to restore the TV-Box
- Method 1-B = We will connect the TV-Box to a PC and then we will restore the TV-Box
1-A Flash with a .img file by preparing an external drive on PC
- We need an SD card or USB memory that will be completely formatted. If do not work with an external drive type try a different one. There may be compatibility issues or our TV-Box can be upgraded only from USB or SD.
- Download the software Burn Card Maker to create your external drive and update or restore your TV Box
- The first thing is to change the language to English to make it more understandable, we go to the upper menu second option
- Select English, OK, close the program and restart.
- In the top “Choose disk” menu select where we have our SD card or USB drive.
Mark “To Partition and Format”
Click on “Open” and select the IMG file of our firmware
Press “Make” to start the process of creating the external memory
- A message will appear that will tell us that the partition system has been generated and we accept
We will see a message to format the drive> Start> OK> Close
- As soon as the formatting process is finished, a blue bar will appear and it will be completed.
Once finished we will have our unit created and we can close the program.
- In the unit that we created we must have three files:
(it is the one that has the whole image of the firmware)
- Connect the HDMI cable and with the TV-Box off (take out the DC power cord) we introduce our SD or USB drive.
We keep the Flash Mode button pressed (some models are inside the audio/av jack) and insert the DC power cord to turn it on, wait for the update percentage to appear automatically in our TV screen.
The process can take from 4 to 12 minutes, wait without disconnecting the TV-Box from the power outlet.
If the recovery menu appears, the process has not gone well, it is necessary to repeat it with another SD or USB.
- The SD or USB device that we used will be left with a special hidden partition that was created in the process, if you want to reuse it and recover all the space it is advisable to use Minitool Partition Wizard , delete all the partitions and recreate a single one.
1-B Flash using a PC connecting to the TV-Box
- Usually you need a USB Type-A to USB-Type-A cable, buy it at Aliexpress or Amazon.
- To update use the flash tool that comes with the rom, if is not included you can use the one in this article.
Older versions are incompatible and give errors during the process.
- Always use a USB 2.0 connector
- If Chinese characters are unzipped in a directory, they must be deleted
- Process for WINDOWS 10 if it gives us detection problems:
Before running the installer of the flashing program we need to disable the secure signature of drivers.
– Windows 10: Start Menu> Settings> Update and Security> Recovery>
Under the Advanced Start option, click Restart Now> Troubleshooting> Advanced Options> Startup Settings> Restart> Press 7 or F7 to Disable the mandatory use of signed drivers.
– NOTE: The computer will reboot and you can install drivers without digital signatures. Restarting the computer again will enable the mandatory use of signed drivers.
Download and install the AMLogic tool (read previous notes for Windows 10). We put two versions, first try with the most modern version that we have available if it does not work try with another older version.
- During the installation the corresponding drivers will be installed. If we see the menus in Chinese we have the option to put English in the second option from the top menu.
- Restart the PC
- Run the tool USB_Burning_Tool that has been installed on your PC and in the File / Import image tab select the .img file that you downloaded with the firmware to install.
- Now with your TV-Box off connect it with the correct USB cable (buy it at Aliexpress or Amazon).
Some TV-Box lights with the power of the own USB OTG others require connecting the power adapter (is better).
After connect keep the Flash Mode button pressed on the device that is usually behind a small hole or inside the audio jack (for the Minix U1 and others of that mark only have to leave the power button pressed until the robot comes out) .
- To flash the firmware you don’t need to see anything on the screen, the TV Box don’t even have to be connect to a screen, only to the PC.
If the “recovery” menu appears on the screen with wipe and other options is that we did not press the button well, retry.
- If everything goes well the flash tool on the PC will recognize your TV Box as in the following image.
– NEVER CHECK THE BOX “Reset after success” and “Overwrite key”
– If we have a red message “Get key failed” or MAC = 0, read point 1-B.1 of this manual
- Press Start and wait for the percentage counter to reach 100%. Once the process is finished, the TV-Box will start again, it will take longer than usual to start, is a best practice to leave it a few minutes without touch after it starts and restart.
- Once installed the new firmware is recommended to do a the factory reset from Settings > Backup.
1-B.1 Fix error Get key failed or MAC = 0
If we have the message Get key failed is that we are missing the license files for the TV-Box, together with the rom or the utility the manufacturer usually has to supply us a file with different files inside, we have to copy those files inside the folder “license ” where we have installed the USB Burning Tool .
- Path where to copy the license files in Windows systems 64bit in 32bit without (x86):
In order for the system to work, we need to uninstall the AMLogic tool , reinstall it and copying the license files BEFORE starting it, then we can boot.
FLASH FIRMWARE VARIOUS FILES OR A ZIP
- Method 2-A = I have only a zip file
- Method 2-B = I have various files and the “” (deep recovery system)
2-A Update with only one ZIP file
With this method we will only perform an update also called OTA, it always comes in a file with a ZIP extension that we should not unzip because the signature of the file will be broken and it will not be possible to apply it.
- Copy update ZIP file to a USB memory or SD card
- We run the UPDATE & RESTORE app, we can have an app icon or be in Settings> About …> Update
- Click on the button (1) SELECT and select the ZIP file.
- Press the button (2) UPDATE to start the update process, accept.
- The process will take a few minutes.
- Once the new update is installed we recommend Factory Reset in the settings of the TV-Box.
2-B Update with various files
Unzip the files to the root of a microSD card (not the Zip that goes inside), see the NOTE if we do it from a USB memory or the update fails.
- Android app: From the UPDATE app on Local update mode, select the USB file and press Confirm.
- Using recovery button: We turn off the TV-Box, insert the SD card, keep press the recovery button and turn on the system.
- Once the TV-Box is updated, is recommended to perform a factory reset: Settings > Factory reset.
- NOTE: If we do the update from a USB memory or the update fails in the recovery we will:
– Apply update from EXT> Update from udisk> Select the firmware Zip
– To end the process do: Wipe Data , Wipe Cache and Reboot System .
FLASH FIRMWARE WITH UBOOT.BIN FILE
- Method 3 = I have several files and the “” (deep recovery system)
With this method you can recover the device from a brick if we no have a way to connect it to a PC, is another option to restore the TV Box.
- For this procedure we will need a MicroSD card that we will formated with the Amlogic BootcardMaker tool for more security (although we can do the formatting from a PC) that we downloaded from HERE .
- Run Amlogic BootcardMaker on our PC and select on the menu “Choose disk” the letter of the drive where we have our MicroSD card and press “Open” to load the Once selected, press Make to format the MicroSD.
file that we downloaded.
- With the MicroSD prepared in our PC we copy all the files that we have downloaded to update our TV-Box (a .zip file, The file is optional or it can also be called . , and ) in the root of the card.
- Introduce the card in our TV-Box with Soc AMLogic.
- Now press the recovery button located at the bottom or inside the A / V connector and at the same time turn on the TV Box. If everything works correctly you will see that an Android robot appears with a percentage bar. When it reaches 100%, the TV Box will reboot only with the new firmware installed.
- Once installed the new firmware is recommended to restore the factory system from settings.
