There are many businesses offering phone unlocking for a fee, but thanks to Simox's Unlock Patch generator, we can unlock Sony Ericsson DB2020 phones ourselves for free. If you are wondering which
phones are DB2020, then here are a few:
In this tutorial, I am going to show you step by step on how to unlock a DB2020 CID52 phone. Warning, do this at your own risk, I am not responsible for any damage caused. Other phones such as DB2010/DB2012 CID49 & 51 phones can also be unlocked using the same basic steps, although it can tend to differ slightly. Requirements
TutorialBecause the Sony Ericsson Update service now updates phones to CID53, we cannot use it anymore! Therefore, to update your EROM to CID52, go into XS++, connect your phone, and you will be asked if you would like to update (click yes). Before we begin, it is also wise to take a GDFS backup. You can do this by simply pressing 'Read GDFS' in SETOOL, and following instructions. If you find the images are blurred, click for a full sized one. First of all, open the Simox Unlock patch generator |
Drag the Main firmware file onto the white area of the Simox Unlock patch generator. The generator will generate the VKP patch into the VKP directory (e.g. If the generator is stored in 'C:\Simox' the VKP patches will be stored in 'C:\Simox\VKP') . (Click the image for the full-sized, un-blurred version)
OK, open SETOOL, and select your phone model (e.g. W610) from the 'phone type' dropdown
Next, check 'Bypass DB2020 Security'
By the files box, click 'Add' and locate the Main firmware file for your phone (the one you used when generating the patch)
In the 'MISC' files box, locate the VKP file generated by the Simox Unlock Patch Generator
Now, hit 'FLASH'. The entire process can take up to 30 minutes, and halfway along you will be asked to remove your phone, remove battery, re-insert it, press 'Ready' and hold C and re-insert your phone. Do not interrupt the process at any time, even if it has appeared to have stopped doing anything, as this could potentially brick your phone. Also make sure you do NOT press anything like 'Write GDFS', as this could also brick your phone.
