Here’s what you need to download the official QMobile X40 stock ROM (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 and were mainly kept in-house, adopted 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 instead. What’s more, installing the QMobile X40 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’ve 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’re often only patching over existing software instead of completely replacing it.
The flashing tools such as the SP flash tool are always computer applications. On most occasions, these apps are relatively small files 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 QMobile X40 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. And depending on the file, there are times when you can flash firmware directly from the device’s recovery mode, too.

How to Flash QMobile X40 Stock ROM Using Smartphone Flash Tool
1. Make sure you have the Android CDC driver installed on the computer that you plan on using the flashing tool on, so your device and the flashing tool can connect. (If you have already installed the Android driver on the computer, then you can skip to the next step. There’s no need to install it twice unless it has been deleted from the computer.)
2. Turn off the QMobile X40 smartphone by holding in the Power button until it powers down, or by switching it off from the Power menu.
3. Download the QMobile X40 firmware file from the link above so the file ends up on your computer.
4. Open the stock ROM file location (usually the Downloads folder) and then extract it (right-click and choose “Extract” from the menu).
5. Now download and extract the Smartphone Flash Tool much the same way as you did with the Stock ROM file. (You can use the desktop as the save location to make things easier if you wish.)
6. Once the SP Flash Tool folder is extracted, double-click to open it and then double-click on the SP Flash Tool application.
7. The flashing tool interface will now open on the computer. From the SP Flash Tool interface, select the “Download” tab.
8. Next, click on the “Scatter-loading file” button.
9. Now browse through the hard drive to the location where you extracted the stock ROM and select the “scatter file” to upload to the flashing tool.
10. Lastly, click on the “Download” button for the flashing to begin.

[*] 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.
