Here’s what you need to download the official Coolpad 7251 firmware (stock ROM) flash file onto a computer. You can then flash the firmware file with the appropriate flashing tool.

Flashing tools were once used only by smartphone repair centers. Since then they have become available on the Web for anybody to use. They allow you to fix the same kinds of problems that were once left up to those repair centers: bootloops, soft-bricked devices, software errors, software bugs, update errors and so forth. And best of all, installing the Coolpad 7251 flash file is simple to do, thanks to the flashing tool’s easy to use interface that usually requires just one click.

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—suggest sticking with custom software if you’ve already changed the system partition or installed a custom recovery. If you are to go back to stock Android, however, they also say it’s always to be done with flashing the firmware yourself instead of accepting the over-the-air updates. This is because OTAs can create unexpected behavior since they often just patch over existing software.

The flashing tools, such as the Qualcomm Flash Image Loader, are always just computer applications. On most occasions these apps are relatively small in file size, that won’t take up much hard drive space.

You can sometimes have a choice of what flashing tool you want to use to flash the Coolpad 7251 stock ROM. Firmware flashing is done with tools that work for either the system chip found in the device’s hardware or, on occasion, specifically made 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 Flash Coolpad 7251 Stock ROM Using Qualcomm Flash Image Loader (QFIL)

Here is how you can use the Qualcomm Flash Image Loader to install firmware on a smartphone or tablet with a Windows computer:

Notes:

  • If you do not see the “Download” button, it is probably because your device is not yet connected to the computer. The flashing only becomes possible if the tool detects a device.
  • The Qualcomm Flash Image Loader is only compatible with the Windows operating system. You can use it on anything ranging from Windows XP through to Windows 10. Newer versions of Windows will also become compatible, but you may need to download an updated version of the tool.
  • Flashing firmware files with flashing tools will result in lost applications and contacts if they are not backed up first. You should backup as much data as you can before flashing: use free applications such as Helium from Google Play, transfer files to the computer, use cloud storage, whatever it takes to be safe.
  • The Qualcomm Flash Image Loader tool is made by the official Qualcomm brand.

1. Install the latest version of the OEM USB driver on the same computer that you plan on using for the installation of the flashing tool.

If there is no OEM USB driver for your device, install the Universal ADB driver instead.

2. Download the latest version of the Qualcomm Flash Image Loader (QFIL) file on the computer, and then extract the file by right-clicking on it and choosing Extract from the menu.

3. Open the Qualcomm Flash Image Loader (QFIL) folder, and then double-click on the QFIL application so that the flashing tool launches.

Tip: It’s the file with the green icon.

4. Turn off the smartphone that you want to flash and hold the Volume Up key and connect it to the computer with the USB cable.

The smartphone should now be in EDL mode (Emergency Download mode) and ready for the firmware flashing. If yours is not in EDL mode, use a search engine to find how to get your specific device into EDL mode.

5. Under Select Build Type, select Flat Build. (click to enlarge screenshot below)

6. Under Select Programmer, click on the Browse button and upload the firmware file that you’re looking to flash to this location. (click to enlarge screenshot below)

The firmware file you need is often the file with the “.mbn” extension at the end.

7. If your firmware has a rawprogram() file, click on the Load XML button and then upload the rawprogram() file to this location. (click to enlarge screenshot below)

8. Give QFIl a few seconds to load the rest of the data automatically.

9. Click on the Download button, and the flashing will begin. (click to enlarge screenshot below)

Note: Firmware files can be quite large and subsequently flashing can take 10 minutes or sometimes even longer. You know the firmware is flashed when the device reboots for the last time.

That’s all.

How to Unroot Coolpad 7251

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 Coolpad 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 Coolpad 7251

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.

Important 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 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.
