W850i Unlocking flash file system?

[sika]

ok i was reading and i got to this part

With SETool2 Lite v1.11.
1. Select your phone model.
2. In Windows Explorer drag (Windows drag and drop operation) the MAIN firmware (*.mbn) onto [SETool2 Lite v1.11 folder]\qamaker\qamaker.exe's icon. In the qamaker's folder you will get a quick_access_XXXX_XXXXXXX.vkp file.
3. Click on ... (three dots) button near MISC files box, and select the vkp file generated in step 2.
4. Tick Bypass DB2020 security check box.
5. Click on Add button and select the MAIN firmware file.
6. Press FLASH button.
7. Follow the instructions given by SETool2 Lite.
8. When a dialog pop-up, click "Yes" to remove the patch. Click "No" to add the patch. In this case click on "No" button.

You need this MAIN - W850_R1EJ001_MAIN_HUTCHISON_CY_RED52 and you will find him in download section - firmware - W850 -
