How to flash DNS S4002
In this article we will understand where to download the firmware on DNS S4002 and how to install or update the firmware on this device “without noise and dust.”
But first, let’s figure out why it is needed.
Why update the firmware on Android
The answer is simple as a penny, often in software, specifically in the shell made by the manufacturer of a smartphone based on Android OS, for example, FlymeOS, there are many flaws and bugs. As a result of these flaws, the user has various problems and inconveniences. Consider the examples:
- Bad shots with a great camera, for example, you have a top camera, like on Oneplus 5, and photos are blurred, “neither fish nor fowl.”
- The smartphone does not want to turn on or restarts itself
- Suspension and understretching
- Very high heat, in this case, it is desirable to lower the processor clock frequency, that is, to do downgrade
- Problems with communication (the problem may be in the hardware, but it is worth trying to reflash)
- Slow response multitouch screen
- Any other problems
There are other reasons, for example, I wanted to get a new functionality or look at a new Android.

Attention! Do not forget to read Denial of responsibility. All actions at your own risk. Be sure to backup the files that you care about!
- The smartphone must be charged at least 30%.
- We will use TWRP Manager, you can download it in our archive with firmware or in the market
- Install TWRP Manager
- Download and download the file with the firmware (located below) and place it on the memory card
- We launch TWRP recovery mode by turning off the phone and holding the power key and the volume rocker up, the display should show “recovery” and the menu as in the screenshot below.
- At first we do data reset (button Wipe). Your smartphone will be cleared completely.
- Then click back and select Reboot recovery, this action needs to be confirmed (usually by swiping right, i.e. drag the slider across the screen to the right)
- Now you can click Install, selecting a file and confirming your intentions. I would like to draw your attention to the fact that the firmware process is not displayed on the screen, therefore you must sit and wait.
So we flash DNS S4002 through TWRP recovery.

- Android Pie 9.0 or just a pie – there’s nothing to say, the best there is now! URL: yourtopfile.info/android9pie

- 7.1 Nougat – suitable for those who have an average or budget-grade iron. URL: yourtopfile.info/android7nougat
- 6 Marshmallow – a thing is certainly good, but morally obsolete, better than something newer. URL: yourtopfile.info/android6
- Android 10Q 2019 is the best operating system for 2019. URL: yourtopfile.info/android10

How to root DNS S4002
This knowledge is so to speak. We can recommend two universal applications for this case:
These are the latest versions at the time of this writing, perhaps there are newer ones that can be viewed on the websites of these programs.
- ZYKURoot 2.4 – (download ZYKUroot 2.4)
- Rootkhp Pro 3.1 – (site rootkhp.pro)
These programs have a list of supported devices, however, this list is updated as horrible, it happens that the device has long been supported by the program, but the developers have forgotten to write about it.
