Introduction

The smartphones of the Russian developer DEXP are quite attractive because of their low cost and good features. Their standard firmware suits most users, because for such an attractive price it is very difficult to find the best value for money.

The company DEXP every day becoming more and more popular in Russia

However, there may be situations when, due to interference with system files, due to incorrect updates, or for other reasons, the device’s performance is impaired. The best way to fix the problem will be the firmware of the smartphone. Fortunately, it is not at all easy to flash the DEXP phone, as the developer equips them with MTK processors, due to which problems almost never arise. We offer on our website a step-by-step guide on how to flash a DEXP phone. You can also download the necessary files and firmware for the most popular models.

Variants of firmware DEXP smartphones

At the very beginning it should be mentioned that the DEXP phone can be flashed both on the official firmware and on the user one. There are quite a few custom firmwares, but not all of them work stably. From what firmware you want to install, will depend on how you need to flash the phone. Perhaps two ways.

Using computer

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

Through user recovery

This method installs the vast majority of custom non-standard firmware. Its huge advantage can be called independence from the presence of a computer, because it may not always be at hand. To flash a DEXP phone through User Recovery, you need to get root-rights, then install custom recovery using a special utility for Android smartphone. After that you need to download the firmware file and install it through the recovery. Getting the root-rights can be the most difficult moment, because in some cases the utilities for getting them work incorrectly.

Preparing for firmware

Before flashing the DEXP phone, you need to prepare for this. Consider what you need, depending on the chosen method.

With firmware 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. Here you can download each of these utilities at the bottom of the page.

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

The second essential component is the Windows driver for your smartphone model. They are vital for the computer to correctly recognize your device and be able to correctly flash it. We 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 with a working USB cable, with which you can connect the device to the computer. In the event of a malfunction, you may not succeed.

With firmware via Recovery

If you plan to install custom firmware, you will have to take a few more measures. But in the future, you can do without a computer.

Getting root rights

Mandatory in this case is getting root-rights. If you have them, your possibilities increase significantly. The best option would be to use the mobile application for Android or the computer program King Root. We will stop our choice on the mobile application, since it has Russian-language menus, whereas the computer program exists only in Chinese.

• Download the application on the smartphone from the official site (//kingroot.net/);
• Install it on the phone, before allowing the installation from unknown sources in its settings;
• Go to the main menu, where we see a large blue button in the middle of the screen.
• Click it and wait for the end of the process;
• Literally in a minute and a half, the application will notify you of the successful acquisition of root-rights.

Installing custom recovery

1. After receiving root-rights, install a utility to change the recovery called Flashify.
2. Launch it, on the main tab “Firmware”, which will be displayed on the screen, click on “Image Recovery”;
3. 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 pre-download the working version of the TWRP recovery;
4. Press the button “Select file”, search recovery.img file using Explorer, confirm the choice;
5. In less than a minute, the application will offer you to boot into an already updated recovery.

Note. A suitable version of TWRP can be downloaded at the bottom of the page.

Alternative installation of user recovery

1. Download the archive.
2. Unpack its contents into the C drive to get the folder C: \ Platform-tools.
3. Download the appropriate version of the recovery, rename the file to recovery.img and copy it to the same folder.
4. We transfer the DEXP phone to fastboot mode, when turned on, hold the volume button up.
5. Next, on the computer, we run the command line as the administrator and subsequently enter the following commands:

cd C: \ Platform-tools

fastboot flash recovery recovery.img

To enter recovery, you need to simultaneously hold down the power button and the volume down.

DEXP Smartphone Firmware

When installing via computer

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

Next, pay attention to the features of the firmware, depending on the installed processor. First, consider the firmware of a smartphone with an MTK processor.

2. We unpack the archive with the computer program SP Flash Tool into the necessary folder, as well as the firmware. It is best to unpack the files to the root of drive C and D.
3. Run the file flash_tool.exe from the folder with the unpacked utility.
4. In the running 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 automatically detected, and also remove the tick from PRELOADER.
5. Turn off the phone, connect it with a cable to the computer and click Download.
6. We are waiting for the process to complete, as we will be notified by a green circle with the inscription Download OK.
7. We wait for the phone to turn on and start using it.

Note. Instead of Download, you can click Options - Firmware-Upgrade, previously ticking the DA DL All With Check Sum. The firmware will start immediately after connecting the device.

Now pay attention to the model with the processor Spreadtrum.

2. Run the utility UpgradeDownload.exe, click the first button on the left and select the folder with the firmware.
3. Click the third from the left edge of the Play button.
4. Turning off the device, connect it to the computer, simultaneously holding both volume buttons.
5. We are waiting for the end of the firmware and begin to use the device.

When installing through recovery

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

1. We translate the device into recovery mode.
2. Go to the "Cleaning" section, mark all items except the memory card.
3. We return to the main menu, click "Install", select the file with the firmware, do the swipe, confirming the operation.
4. We are waiting for completion.
