Here’s what you need to download the official Samsung SM-M405F firmware flash file onto your computer. You can then use one of the compatible flashing tools to update the firmware on your smartphone or tablet.
Flashing tools were initially developed by the companies that were associated with the device’s hardware, kept in-house, used in the back rooms of smartphone repair centers to fix common mobile device-related problems. The tools were later published on the Web for anyone to use. Now you can solve the same kinds of issues that were once left up to those repair centers: bootloops, soft-brick situations, software errors, software bugs, update errors, so forth, by downloading the software onto your computer at home instead. What’s more, installing the Samsung SM-M405F flash file is an easy task, thanks to the flashing tool’s user-friendly interfaces that usually require just one click before the flashing is underway.
Most third-party developers who create tools for helping you customize your devices—the teams that work on custom recovery images, rooting applications, et cetera—recommend sticking with custom software if you have already changed the system partition or replaced the stock recovery partition with a custom one. If you are to go back to stock Android on the device, though, they strongly suggest flashing the firmware yourself instead of accepting the over-the-air updates. This is because OTAs can create unexpected behavior since they are often only patching over existing software instead of completely replacing it.
The flashing tools such as the Odin Flash Tool are always computer applications. On most occasions, these apps are relatively small files and will not take up much hard drive space.
You can sometimes have a choice of what flashing tool you want to use to flash the Samsung SM-M405F stock firmware file. You can flash stock ROMs with tools that work for either the system chip found in the device’s hardware, the firmware file type, or on occasion, apps that are designed to work for a particular manufacturer.
What Is Android Firmware?
Firmware is the operating system and its applications that control how the smartphone or tablet that runs on Android operates. While you may see the words “software update available” on your device’s display, we call it firmware to highlight its close relationship with the device manufacturers hardware.
If you prefer technical jargon, firmware is the specific programming that gets written to a device’s non-volatile memory. The firmware gets added to the device during the manufacturing process and is the middleman in helping software run on the hardware. Firmware can be written as read-only memory (ROM), erasable programmable read-only memory (EPROM), or flash memory.
The Android operating system is more open than much of its competitors in iOS, Windows 10 Mobile, and Tizen. You always get firmware running on your device out of the box, but if you do not like it, you can swap it over with custom firmware or other firmware versions that were made for your device. This flexibility helps with troubleshooting, or if you know you would prefer a different Android version that was made available.
Why Reinstall Stock Firmware?
Did you think you may need to restore the stock firmware on your device? Here are some of the things that you can achieve with stock firmware files:
- Upgrade or downgrade the version of Android on your device
- Fix common mobile device-related problems, such as unbearable bugs in the software
- Remove custom recovery images such as TWRP
- Unroot the Android operating system, regardless of what method/tool you may have used to get root access
- Unbrick your smartphone or tablet
- Reinstall the operating system
- Fix invalid IMEI problems

How to Install Samsung SM-M405F Flash File Using Odin Flash Tool
To install the Samsung SM-M405F firmware, you need to use a flashing tool that works for your manufacturer and run it on a computer. One flashing tool that works for this smartphone is the Odin Flash Tool. Here is how to use it:
- Back Up Your Data. You should always back up your data before you begin flashing new firmware files to your smartphone or tablet. All your pictures, music, videos, documents, etc. should be still on your device after you have updated the firmware, but you may need to restore the contacts and applications from a backup.
- Wipe Cache and Factory Reset. Some people claim that taking a factory reset isn’t necessary after updates, but at the very least you should wipe the system cache after installing new firmware. This way you can help eliminate any performance issues and battery draining bugs. Taking a factory reset is the best way of avoiding common problems many users face after applying software updates.
- The Odin flashing tool is straightforward to use, but it only works on the Windows operating system. You won’t get the flashing tool to load on a Mac or Linux computer. It doesn’t matter what version of the Windows operating system that you’re using as long as it is something above Windows XP.
- The guide below works if your firmware file contains the tar.md5 file. If you ever need to flash Samsung firmware using the full stock ROM files individually instead, you can learn how to flash Samsung stock firmware using all four files. (Check your firmware file after you download it to see if it is a tar.md5 or comes as 4 individual files.)
Before We Begin
- Make sure you have:
- A desktop computer or laptop that is running on a version of the Windows operating system (ideally Windows 10 but at least Windows 7).
- A USB data cable that allows you to connect your smartphone or tablet to the computer.
- The tar.md5 file/files you want to flash to the smartphone or tablet.
- You need to install USB drivers on the computer that allows for your smartphone or tablet to connect with the flashing tool. Several drivers can achieve this. If the drivers in the tutorial do not work for your device, try getting in contact with your smartphone’s manufacturer via an official website or phone number.
- We recommend backing up the smartphone or tablet before getting started. The Odin Flashing Tool is a reliable tool, but whenever you are installing firmware—regardless of the tool—it is possible you may want to restore the old version of your device. You can only do that from a backup.
- You need to download a version of the Odin Flash Tool during the tutorial. You should always download the latest version of the tool. If that version does not work, try using an older version. Latest versions of tools have the best chance of being compatible.
1. Download the Samsung USB drivers and install them on the computer if you do not have them already.
2. Download the stock firmware package from the links above directly to the computer. Extract the file by right-clicking on it and choosing the option to extract.
3. Download the Odin Flashing Tool. Any version should work, but the latest is the most up to date so grab that one. Extract the Odin file and then double-click on the Odin executable file (.exe) that is found from within the Odin folder after extraction.
You will need to download it from a third-party because it was never officially released by Samsung. Many websites are hosting the Odin flashing tool these days, including the file hosting website that we’ve linked to. You can always give your files a VirusTotal scan before downloading them just to be sure.
4. Generally speaking, you want to download the latest version of Odin as it has the most chances of being compatible with what you’re flashing.
5. Once you have got Odin downloaded on the computer, extract it and then open it up so you can see its interface and just leave it there in the background of your desktop.
6. Now download your firmware that you want to flash. You need to make sure you have the right firmware made for your device.
For example, not all Samsung Galaxy S10 smartphones are the same: there can be different hardware and other regional differences inside that can result in minor or major problems if you get it wrong.
7. Boot the mobile device into the Download Mode by first powering it down and then rebooting by holding the Volume Down + Home + Power keys at the same time.
Assuming you already have the USB drivers installed on the PC, Odin should now detect your device by changing the color of the ID: COM port from its interface to a color which is usually blue or yellow.
8. Lastly, you need to upload the firmware files to the Odin flashing tool. To do this for a full stock ROM, you need to open the firmware folder and then locate the four following files:
- BL: Bootloader file
- AP: Android partition
- CP: Modem firmware
- CSC: Consumer software customization
9. Each file that you need to upload from the firmware folder will be marked BL, AP, CP, or CSC on the actual firmware files themselves so you can easily see them.
Note: You may not always be able to downgrade your firmware from Samsung or carriers working with Samsung. Sometimes extensive software updates are given downgrade blocks. There’s no way of being able to tell if your device has been downgrade blocked without checking reports from other users and doing lots of reading on relevant web forums.
How to Unroot Samsung SM-M405F When Installing New Firmware
There can often be a variety of ways to unroot a device that runs Android, and they depend on what method you used to get root access. If you installed SuperSU for root access, then you can open the app and find the option to unroot directly from SuperSU’s settings. On the other hand, if you do not have SuperSU, and you do have a Samsung smartphone or tablet, then you can always unroot by installing the stock firmware. Once you have followed the guide above, your device will automatically be unrooted. You can verify that is the case by installing one of the many applications from Google Play that checks for root access. As long as you are using a reliable app, then typically it will not lie about the root status of your mobile device.
How to Go Back to Stock Recovery on Samsung SM-M405F When Installing New Firmware
One of the most common reasons for installing the stock firmware is to remove a custom recovery image and go back to the stock recovery. There is nothing you need to do extra to make your device go back to the stock recovery; when you install the stock firmware, it will automatically install the stock recovery partition on the device once again.
You can download Android firmware for other Android devices if you have another smartphone or tablet from a different manufacturer.
