I am refering to applying the quick access patch using the flash button in the step before you apply the generated patch using script.

The error you made is in not waiting at this point.

<snip>
With SETool2 Lite v1.11.
1. Select your phone model.
2. In Windows Explorer drag the MAIN file (.mbn) onto [SETool2 Lite v1.11 folder]\qamaker\qamaker.exe. 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 checkbox.
5. Click on Add button and select the MAIN firmware file.
6. Press FLASH button.
7. Follow the instructions given by SETool2 Lite.
8. READ THIS CAREFULLY, it is a little tricky: When a dialog pop-up, click "Yes" to remove the patch. Click "No" to add the patch. In this case click on "No" button.

At one moment you will belive that nothing happens and the status windows is not changing! DO NOT remove the CABLE! Wait until "ELAPSED x SECONDS" appears in status window.

you are referring to the next step in the process

you must redo this quick acess patch and wait till it writes before you can proceed.

Do it again from the begining
