Here’s what you need to download the official Samsung B310 firmware flash file onto your computer which can then be flashed with an appropriate flashing tool, one that will either flash firmware for your device manufacturer or system chip found in the hardware.

Speak to anyone who loves the Android operating system, and you’re bound to keep hearing one of the top reasons why they have so much admiration for it is Google doesn’t lock it up and throw away the key as Apple does with the Cupertino company-owned iOS software.

The way Google manages Android is with enough restrictions so that you, the end user, gets to use the operating system with lots of security, but also with enough respect for you that you get to call the shots with how you want to use it.

Feel like taking a bit of a security risk on your own behalf and grant yourself the all-important administrative permissions so you can install every application out there? Google makes it possible for you to root each version of the Android operating system whenever you choose.

And the fun doesn’t stop there either. Ever wondered how most people without root access get a custom ROM installed? They do it from a custom recovery image—another way that you can customize the device away from the default Android ROM that your device came shipped with.

Many iOS users don’t have a great deal of respect for the Android environment: they often say it’s messy, there are far too many versions being used at once, and so on. But you also need to understand that one of the main reasons for so many different versions of Android being run at once is because there are so many different devices out there, each with different hardware specifications and there is hardware out there that can’t necessarily run on anything close to the latest Android version that’s been released.

Keeping software on your device that works well is one of the most important things you can do. And even when you do everything by the book, it isn’t necessarily still going to give you the best user experience: you might still find your software has some bugs, you could encounter software errors, it’s possible you get stuck in boot loops, and so forth.

If you do find yourself in a situation where your software has seemingly gone askew, you don’t have to just wait around and hope for an OTA update to arrive soon. You can take matters into your own hands and update the device’s firmware by installing it with a flashing tool. You can flash firmware files to help solve any software-related problems you might be having of if you tried customizing your device and got it stuck in a bootloop aka soft-bricked it for the time being.

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 B310 Flash File Using Spreadtrum Upgrade Tool (SPD Upgrade Tool)

To install the Samsung B310 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 Spreadtrum Upgrade Tool. Here is how to use it:

Notes:

  • Back Up Your Data. You should always back up your data before you begin flashing new firmware files to your smartphone or tablet. All of 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 is not 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.

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 scatter loading 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, or use a driver that works for Spreadtrum-based chipsets.
  • We recommend backing up the smartphone or tablet before getting started. The Spreadtrum Upgrade 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 Spreadtrum Upgrade 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 SPD Upgrade Tool onto your computer and then extract the file by right-clicking on it > clicking Extract from the menu so you can use it.

2. Download the official OEM USB driver for your manufacturer onto your computer, or try using the Android USB driver or Universal ADB driver if your OEM is not listed.

3. Turn off the smartphone by long-pressing the Power button.

Some experts recommend removing the battery if your smartphone comes with a removable battery. Most newer smartphones do not come with removable batteries so you will not be able to do it. Since most people use the flashing tool without removable batteries, it is fine for you to use the tool without having removed your battery.

4. Download the stock or custom firmware that you want to install on your smartphone or tablet and then extract the file by right-clicking on it > clicking Extract from the menu so you can use it.

5. Double-click on the SPD Upgrade Tool application to open it.

If you get a message from Windows stating that “Windows Defender SmartScreen prevented an unrecognized app from starting. Running this app might put your PC at risk,” click on the More info link and then click on Run anyway to open the file.

This is how the Spreadtrum Upgrade Tool, aka UpgradedDownloaded, appears in File Explorer/Windows Explorer after you have extracted the file. Note the pictured icon, as well as the fact it is listed as an “application” in the Type column.

6. Connect your smartphone or tablet to the computer with the USB cable, ensuring the mobile device is still turned off.

If you removed the removable battery, place the battery back in before proceeding to the next step.

7. From the SPD Upgrade Tool’s interface, click on the Load Packet button and upload the .pac firmware file to this location. (click to enlarge screenshot below)

The Spreadtrum Upgrade Tool does not show names next to the buttons, but you should be able to hover the cursor over the buttons to reveal the names if you need confirmation on which buttons are which.

8. One the .pac firmware file has been uploaded to the UpgradeDownloaded interface, click on the Start Downloading button. (click to enlarge screenshot below)

The “Start Downloading” button can be distinguishable by its triangle shape, similar to a traditional Play button.

9. The firmware flashing now begins automatically. During the flashing, your device may restart several times before the process is complete. You know the flashing is finished when you get a “Pass” message in the Progress column.

You can now unplug your smartphone or tablet from the computer if you like.

That’s all.

How to Unroot Samsung B310 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 B310 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.

Additional Firmware

You can download Android firmware for other Android devices if you have another smartphone or tablet from a different manufacturer.
