How to flash or reflash a DEXP smartphone

Using a computer

In this way, official firmware is installed, as well as some custom ones. You will need to install the SP FlashTools utility, device drivers and download the firmware file on your computer or laptop, then connect the phone to the computer and complete the process using the computer utility. This option is the simplest. The most difficult part may be installing the driver on your computer. The whole process takes literally a few minutes.

Via custom recovery

This method is used to install the vast majority of custom non-standard firmware. Its huge advantage is its independence from the presence of a computer, because it may not always be at hand. To flash a DEXP phone via custom Recovery, you need to get root rights, and then install a custom recovery using a special utility for an Android smartphone. After that, you need to download the firmware file and install it through recovery. The most difficult part may be obtaining root rights, because in some cases the utilities for obtaining them do not work correctly.

Preparing for firmware

Before flashing your phone with DEXP, you need to prepare for it. Let's look at what you'll need, depending on the method you choose.

When flashing via computer

By and large, the main tool is a special utility SP FlashTools (for models with an MTK processor) or UpgradeDownload (for models with a Spreadtrum processor). It is with their help that we will install new firmware on our DEXP phone. From us you can download each of these utilities at the bottom of the page.

We immediately warn you that “the latest” does not mean “the best”; in addition, in some cases you may need a certain version of the utility that works most stably with a specific firmware.

The second required component is Windows drivers for your smartphone model. They are vital for the computer to correctly recognize your device and be able to flash it correctly. From us you can download drivers for the most popular models. You also need to download the firmware file you want to install.

In addition, be sure to stock up on a working USB cable with which you can connect the device to your computer. If it malfunctions, you may not succeed.

When flashing via Recovery

If you plan to install custom firmware, you will have to take slightly more measures. But in the future you will be able to do without a computer altogether.

Obtaining root rights

In this case, it is mandatory to obtain root rights. If you have them, your capabilities increase significantly. The best option would be to use a mobile application for Android or the King Root computer program. Let's choose the mobile application, since it has Russian-language menus, while the computer program exists only in Chinese.

Download the application to your smartphone from the official website (https://kingroot.net/);
We install it on the phone, having first allowed installation from unknown sources in its settings;
We go to the main menu, where we see a large blue button in the middle of the screen.
Click it and wait for the process to complete;
In just a minute or a minute and a half, the application will notify you that you have successfully obtained root rights.

Installing custom recovery

Once you have root access, install a utility to change your recovery called Flashify.
We launch it, on the main tab “Firmware”, which will be displayed on the screen, click on “Recovery Image”;
Next, you will be asked to select a file or automatically download the appropriate version of one of the most popular versions of custom recovery. It is best to first download a working version of TWRP recovery;
Click the “Select file” button, look for the recovery.img file using Explorer, confirm the selection;
In less than a minute, the application will prompt you to boot into the already updated recovery.

Note. The appropriate version of TWRP can be downloaded at the bottom of the page.

An alternative option for installing a custom recovery

Loading the archive.
Unpack its contents into the C drive to create the C:\Platform-tools folder.
Download the appropriate version of recovery, rename the file to recovery.img and copy it to the same folder.
We put the DEXP phone into fastboot mode, holding the volume up button while turning it on.
Next, run the command prompt on your computer as an administrator and sequentially enter the following commands:

cd C:\Platform-tools
fastboot flash recovery recovery.img

To enter recovery, you need to simultaneously press the power and volume down buttons.

How to get root rights

This is knowledge loaded so to speak. We can recommend two universal applications for this case:

These are the latest versions at the time of writing, there may be newer ones, this can be viewed on the websites of these programs

ZYKURoot 2.2 – (website zykuroot.info)
Rootkhp Pro 2.7 – (website rootkhp.pro)

These programs have a list of supported devices, but this list is updated haphazardly, so it happens that a device has been supported by the program for a long time, but the developers forgot to write about it.

Firmware for DEXP smartphones

When installing via computer

Install drivers on the computer. If you are using Windows 8 or 8.1, you will need to disable digital signature verification. To do this, press Win + C - Settings - Change computer settings - General - Special boot options. The computer should restart, then click Diagnostics - Selective Boot. After rebooting again, when a list of 9 items is displayed, press F7 and install the drivers in the usual way.

Next, let's pay attention to the features of the firmware, depending on the installed processor. First, let's look at the firmware of a smartphone with an MTK processor.

Unpack the archive with the SP Flash Tool computer program, as well as the firmware, into the desired folder. It is best to unzip the files to the root of drive C and D.
Run the flash_tool.exe file from the folder with the unpacked utility.
In the launched window, click Download - Scatter-loading and look for the file MT65xx_Android_scatter.txt in the folder with the firmware, after which all the necessary files will be detected automatically, and also uncheck PRELOADER.
Disconnect the phone, connect it via cable to the computer and click Download.
We wait until the process is completed, which we will be notified by a green circle with the inscription Download OK.
We wait for the phone to turn on and start using it.

Note. Instead of Download, you can click Options - Firmware-Upgrade, after checking the box for DA DL All With Check Sum. The firmware will begin immediately after connecting the device.

Now let's turn our attention to models with a Spreadtrum processor.

Launch the UpgradeDownload.exe utility, click the first button on the left and select the folder with the firmware.
Click the third Play button from the left.
We turn off the device, connect it to the computer, simultaneously holding down both volume buttons.
We are waiting for the firmware to finish and start using the device.

When installing through recovery

Subtleties may vary depending on the firmware, but the principle is as follows:

We put the device into recovery mode.
Go to the “Cleaning” section, check all the items except the memory card.
We return to the main menu, click “Install”, select the file with the firmware, make a swipe, confirming the operation.
We are waiting for completion.
