How to apply the generated patches to DB2020 CID52 phones:


IMPORTANT: First you need backup the GDFS. If something goes wrong you can unbrick you phone with this backup. Here is how to do:
Open SETool2 Lite v1.11.
1. Select your phone model.
2. Click on Read GDFS button.
3. Follow the instructions given by SETool2 Lite.
4. You will get a gdfs_yourIMEI.bin file in SETool2 Lite folder. Put it to a safe place.


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!!!

Open 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. 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.

This process will take some time, about 10-15 minutes or more...

II. Now we need to generate an unlock patch.
Run SIMLockPatchGen.exe, select that MAIN firmware (used earlier) by clicking on ... (three dots) button, then press the Make patch button. In status window you will get the path to the generated vkp file(e.g. "D:\...\SIMLockPatchGen\vkp\Remove_SIM_lock_XXX_XX XXXXX.vkp" patch file created.) Close the SIMLockPatchGen.

III. We will apply the generated unlock patch to unlock the phone.
In SETool2 Lite v1.11:
1. Click on Clear button.
2. Select your phone model.
3. Tick Use "quick access" patch checkbox
4. Click on ... (three dots) button near MISC files box, and select the vkp file generated by SIMLockPatchGen.
5. Click Write SCRIPT button
6. Follow the instructions in left status window...
7. READ THIS CAREFULLY, it is a little tricky: Click "Yes" to remove the patch. Click "No" to add the patch. In this case click on "No" button.

Wait until "ELAPSED x SECONDS" appears in status window, and done. Your phone is unlocked.
