Hi all, I have a question about the following part of the tutorial:

B. How to apply the generated patches to DB2020 CID52 phones:

...

I. We will apply the quick access patch to phone. It is needed to be able to use the quick access method in future. Due to this great patch you can easily apply the further patches, just like to DB2010 CID 49 phones.
!!!YOU NEED TO DO THIS ONLY ONCE!!!

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.

Note: After pressed the FLASH button, at one moment you will believe that nothing happens and the status windows is not changing! DO NOT remove the CABLE! Wait until "ELAPSED x SECONDS" appears in status window.
This process will take some time, about 10-15 minutes or a little more...

I have successfully unlocked my phone thanx to this but I now have a question which I need answered to help a new member of this forum.

When I did it, for this step, I used the same MAIN version as the one which was originally on my phone.
What I want to know is, what would happen if you used some other MAIN? Would it actually replace the old main with this new one, and apply the QA patch at the same time?

So for instance if I had R1CF001 on my phone, and I used R1ED001 main for this step, would the new firmware on the phone be the R1ED001 with the QA patch installed. If so, the next step would be: apply the unlock patch, flash FS and CUSTOM to match the new MAIN?

Thank you and regards,
