How do i sim network unlock K770i

I am a newbie. I need to unlock my daughters K770i from the network 3 to be able to work on O2.

I have the following:

XS++
setool2lt v1.11

By using setool i have used the identify to retrieve:

Version: R8BC004
CID:52
Color: RED
Network: Locked

I have tried all different methods to try and unlock the sim looking at various threads on forums and still cannot unlock the network.
Could someone tell me how to do this step by step.

I have backed up the phone and have already killed the phone once but managed to use XS++ to revive it.

This is of course just patch unlock so if you re-apply firmware, you will have to follow these steps again but hey, it's a small price to pay!!!

You will need the following:

SIMLockPatchGen 2 (free from http://simox.5gbfree.com)
SETOOL2LITE (v1.10)
XS++ (v3.1)

SIMLockPatchGen 2

First of all you need to create the unlock patch

Load up the software and then select the MAIN firmware you wish to make the unlock patch from (I presume that this can be any but I chose the K800_R8BA024_MAIN_GENERIC_WI_RED52.mbn), it should auto detect which phone it is for and the firmware version.

Click on Make Patch and it should create a VKP file (this is located in VKP directory inside the directory SIMLockPatchGen 2 is installed to).

Ok, now time to move on.

SETOOL2LITE

Load up the software and change the Phone Type to K800.

In the big box on the right (Files area), click on Add and select the MAIN file and then do the same again and select the FS file (make sure this corresponds to the MAIN file you created the patch from in the previous step - NOT A DIFFERENT FIRMWARE FILE).

Now, in the MISC files area, browse to the VKP file that was created before ...

Now click on the FLASH button

Connect the phone as per usual by taking out the SIM card, then the battery. Re-insert the battery and whilst holding down C button on the phone, connect it to the USB cable (other side of it should already be plugged into your computer).

Flashing will begin. After a while, it will ask you to remove the cable, remove the battery, re-insert battery, click READY and then re-connect it to the USB cable whilst holding down the C button.

Again, after another while, it will ask you about the script file, just click on the NO button to apply.

After a couple of minutes, it will be completed and you can disconnect the phone from the USB cable.

XS++

Load up the software and click Connect.

Remove the battery, re-insert battery, and then connect it to the USB cable whilst holding down the C button.

Ignore Flash File System and Main Firmware.

Instead, click on the third box (Customize File System)

Select phone model to K800

Then select CDA and Region (you can look on the left hand side and see what CDA you already have), just check in the drop down list and find the one that matches. Even if not then find the one that is closest (didn't do mine any harm).

When Ready, click Flash.

After a minute or so, once complete, disconnect USB cable remove battery from phone, insert ANY SIM CARD from ANY PROVIDER, re-insert battery and switch on ... hey presto, you are unlocked!!!

I hope this helps people as I am so impressed I figured it out, took me a while like I say ... Also, don't flame me for this or be nasty, I am genuinely trying to help people do all of this that certain companies charge a fortune for for free!!!

Good luck!!!

Follow this tutorial and you can't miss Remove SIM-lock patch generator - Top Sony Forums

Thanks for the information to which i have followed step by step, but the phone will still not unlock from the network 3.

I did notice that when i used setool lite it came up with an error at the end for some reason.
I have tried using the K770i and the K800 files which don't seem to work.
I will post the results in the next post.

Here we go, i tried using the K800 mbn and fs files with XS++ and killed the phone, so i flashed it back with the K770 files and is now working.

These are the files i originally used:

K770_R8BA024_MAIN_GENERIC_VI_RED52
K770_R8BA024_FS_CENT_EUROPE_RED52.fbn

and produced with simlockpatchgen which is the vkp file
Remove_SIM_lock_K770_R8BA024

Here is the log when i use setool2 lite Flash using the above files (using phone type K800as K770 is not in list):
