How to use SP flash tool to flash a stock rom
This tutorial is to teach you how to use SP flash tool(Smart Phone flash tool) to flash a stock rom.
To flash a rom,you will need:
-The mtxxxx preloader drivers
The “xxxx” is the model of processor in your device,you can check it in the specifications list of your device here.Then get the drivers you need here.
-SP flash tool
Download latest version here.
-A stock rom
Download Doogee roms here.
-A USB cable
Some of the steps may need you to try many times,please be patient!
I am using a Doogee F5 to do this tutorial.The steps are the same to other Doogee models.
Notelease do not use any Rom that is not specified for your device,otherwise it will brick your device.
1.Get necessary drivers and install them
The package should contain files shown as below.
Just leave them for a while.Go to step 2.
2.Clear all the existing drivers that are relative to MediaTek
Search USBDeview on Google and download the latest version.Use it to uninstall all MediaTek drivers that have been installed before.
Right click on the driver,then click Uninstall Selected Devices from the list.
3.Install the mtxxxx preloader drivers.
Right click InstallDriver.exe - Run as administrator.
The program will run automatically and finish the installation like this.
Right click Computer - Manage -Device Manager
In Device Manager,choose one of the groups,then click on Action - Add legacy hardware
Choose Install the hardware that I manually select from a list (Advanced)
Show All Devices - Next
Click Have Disk and browse the driver file
Locate file in the mt67xx preloader driver folder,access the following folder according to the operating system of your computer
For Win 7 32-bit system, select usb2ser_Win7.inf
Win 7 64-bit system,select usb2ser_Win764.inf
Select MediaTek Preloader USB VCOM Port,click Next
Start the installation,click Next
Finish the installation
Check Device Manager,there should be the MediaTek preloader driver
* If SP flash tool or other software still don’t detect your phone then also install MediaTek DA VCOM (consider installing more from the list of drivers one at a time if need be)
* If you get the code 10 error after the installation, simply ignore it and proceed with SP flash tool. You're only getting that error because the driver is not digitally signed.
4.Start to flash a rom
Right click the tool - Run as administrator
Click Scatter loading button
Choose the scatter.txt file.It is located in the ROM folder,which is extracted from the stock ROM downloaded from Doogee website
Choose Download Only in the setting,then click Download
Now connect your phone to PC via a USB cable,make sure the battery has been removed.If the battery is unremovable,just keep the phone shut down.
If no reaction after connecting,disconnect the phone,press the volume+ button then connect the phone again until it works.This step may take you several times to achieve.
If the phone is detected correctly,the status bar will run by itself.
Wait until the process is done.
This means you have flashed the stock rom successfully.Congratulations!
