Free unlock of Sony Ericsson DB2020 phones (w610i, k800i, k810i etc) NOT Cid53
POSTED BY: shanecr 6 months, 2 weeks agook, first off i take no responsibility for anyone following this guide and bricking their phone.
This is also not completely my guide but one made from a couple other guides with some pictures.
i have used this myself and had it work and also helped t0mm unlock his phone.
Just use the supplied cable that came with your phone.
please note, i will update this with more pictures later to make it even easier to follow
note: the model number i am using here is w880i, this is suitable to use for unlocking k770i
Please note: This will NOT work with the w810i.
- t0mm
this will not work for Cid53 versions - Shanecr
It has been brought to my attention that connecting a k800i to seus will upgrade it to cid53 and therefore can not be unlocked via this method. please download drivers via other means.
For W810's use this thread:

WARNING - CONNECTING TO SEUS WILL UPGRADE YOUR PHONE TO CID53 AND THEREFORE UNLOACKABLE VIA THIS METHOD
to double check your phone is db2020, enter the service menu - > * < < * < * Go into Service Info and then Software Info, just after you see EROM you should hopefully see DB2020, if not then your phone most likely isn't suitable for this unlock.  This unlock works by applying a patch to your firmware to allow a software patch to be applied. If you update your firmware after this unlock then your phone will most likely become locked again. The unlock patch is made using a patch generator from Simox - http://simox.5gbfree.com/site/request.php?9 you will need to download the firmware to match your phone - http://sek750.extra.hu/letoltes/?path=./Firmware/ Once you have these you can make the unlock patch for your phone. Open SimlockpatchGen and browse to the firmware file you downloaded Click 'make patch' and it will make a .vpk file which you will use later to unlock your phone.

Next step is applying the patch. For this you can use SeTool 2 lite -
setool2 lite It is reccomended you download SEUS first and update your phone. This will also install nesscesory drivers without which SeTool lite wont work (this was my own personal experiance)- LINK REMOVED - SEUS UPDATE MAY LEAVE PHONE UNLOCKABLE VIA THIS METHOD. INSTALLING YOUR PHONE MODEL SUITE SHOULD ALSO INSTALL REQUIRED DRIVERS Once this is done Open setool lite, find your phone in the drop down menu and select read GDFS  switch off your phone, remove battery and reinsert battery, connect to computer whilst holding down the 'c' button Once this part is finished se tool will say 'Elapsed: ??secs' Last edited by shanecr : 12-08-2008 at 17:55. |

Now we need to apply a quick access patch to the phones fimware.
remove from and remove battery before reinserting it again. open se tool and check the 'bypass security' and select your phone in the drop down menu. Add your phones firmware file into the main box Then in misc browse to Qamaker folder in the setool lite folder. you should select the quickaccess .vpk file that matches your phone model and firmware.  (If you can not find a file to match then there is an exe file there to make one, just drag your earlier downloaded firmware file on top of the exe file and the appropiate quick patch file will be generated)  Hit FLASH and connect your phone holding the 'c' button Setool will run and when finished it will ask you unplug your phone. remove phone, remove battery, reinsert battery and the press READY on setool. Then reconnect phone holding the 'c' button Setool will then run again and a window will pop up Select NO to apply the patch. A few seconds later the patch will apllied and this part of the process finished. Remove phone, remove battery and reinsert battery. Last edited by shanecr : 11-02-2008 at 22:04. |

Now to apply the unlock patch.
Start up setool and select your phone model in the menu. check the 'apply quick patch' box in misc browse to the unlock patch .vpk file you made earlier (n the simlockpatchgen folder)  Hit write script and reconnect your phone holding the 'c' button. again a box will pop up where you select NO to apply the patch. Setools will run and when finished your phone is unlocked! Last edited by shanecr : 11-02-2008 at 23:20. |

Nice guide shanecr Can't say for certain, but I'm pretty sure the normal cable is all you will need

siewmk:
I had a quick search on internet about this and one suggest a special cable is required. This is why I'm hesitate to use it on my phone coz if not careful, i'll brick the phone. I'll wait and see if there is anyone who have tried it... thanks anyway for replying. Cheers.  as stated in op i have done this as has t0mm from this forum, both with the original supplied cable. |
