Steps to use FlashTool to backup Mediatek Smartwatch firmware

Follow the steps below to backup a Mediatek (MTK) Smartwatch's firmware with FlashTool

Part 1: Extracting the raw ReadBack (ROM_0) file

1. Extract and run Flash_tool.exe as Administrator 
   
   
   
   
2. If Download Agent doesn't contain a path to MTK_AllInOne_DA.bin then click the Download Agent tab
   
   
   
   
3. In the Window that pops up, navigate to the FlashTool folder, highlight MTK_AllInOne_DA.bin and click Open
   
   
   
   
4. Click the Scatter / Config file tab
   
   
   
   
5. In the Window that pops up, navigate to the location of the config or scatter file, highlight it then click Open
   
   
   
   
6. Depending on what other files are in the same folder as your config / scatter file, you might or might not get a read file failed error. Now, click the Read Back tab at the top
   
   
   
   
7. Highlight whatever entry you find under ReadBack and click Remove
   
   
   
   
8.  Click Add
   
   
   
   
9. A new entry should appear, double-click it
   
   
   
   
10. In the Window that pops up, navigate to the folder you wish to save the ROM_0 file then click Save
    
    
    
    
11. In the Readback block start address tab that pops up, set Start Address as 0x00000000 and Length of whichever block you wish to stop (a full ReadBack often has length of 0x01000000 , 0x00800000 or 0x00400000) then click OK
    
    
    
    
12. Click Read Back (with an arrow above it)
    
    
    
    
13. Stop should now be Red in color. Power off the Smartwatch (with battery inside) then connect to PC via USB without holding the Power button
    
    
    
    
14. The Smartwatch should get detected, do not interrupt the process
    
    
    
    
15. Once Read Back is done, you should see a green circle. You may now disconnect the phone and close FlashTool
    
    
    
    
16. Check the ROM_0 file
    
    
    

Part 2: Processing the ROM_0 file

1. Extract ReadBack extractor into the same folder as ROM_0 and launch it
   
   
   
   
2. Click Load Readback file
   
   
   
   
3. In the Window that pops up, navigate to the folder where the ROM_0 is located, highlight the file and click Open
   
   
   
   
4. Wait while the file is checked 
   
   
   
   
5. If the file is OK then you should see Binary file report: health 100% . Click Rebuild Firmware
   
   
   
   
6. Wait while the firmware is being rebuilt 
   
   
   
   
7. Once Rebuilding is completed, you should see ALL DONE and the rebuilt files in the same folder as the ROM_0 file
   
   
   
   
8. You may close ReadBack extractor
   

Important Notice

• Avoid interrupting the backup process as this could cause the smartwatch to go dead
  
• If Flash Tool has trouble detecting your smartwatch then ensure to use the latest version
  
• If you get an error while trying to use readback extractor then try cutting the rom using fwsplitter tool ; see the usage @ https://www.hovatek.com/forum/thread-321...#pid186307

Hi Admin. How do I get the .cfg file for my V8 watch

search online for the firmware for your smartwatch model; you can get cfg file from there OR you use the cfg file of any other watch running the same chipset as yours

Hello Admin,
I am getting problem to take back up of my Y1 watch with MT6261D . I have installed all the drivers from your driver folders, 1 by 1.Though all those are showing in Yellow marks. Then i was following the tutorial of the back up process. What i noticed the differences, the port in your screenshot are showing searching before you started Read back process and after connect watch its changed to Com port. Also the type, before read back was showing NOR, later NFB.. In my case, its always showing the com1 (communication port of pc)not searching, also always showing NOR the type.
Can you please help me what is going wrong? Also if possible the set up of the Flash tool..

I also forgot to tell, when i connecting my watch (switched off) its started the charging process. I am a beginner.
Thank you for your help.

Thank you for your reply. I have tried that option as well, but its not popping up any message, even its not showing something is connected.. I am in total dark in this situation. The watch just start charging when its connecting the PC, not other pop up in computer.
