K610 far bflash problem

Hi,

I've been trying for a week to unlock sony ericcson k610i. I've read all tutorials for do it with far or setool2 lite. My problem is the following:

1) I've used far to do all the process.
1) the cid from my phone was 49. I've upgraded to Cid52, flashing it with K610_R1KG001_MAIN_GENERIC_TH_RED52.mbn and K610_R1KG001_FS_EUROPE_1_RED52.fbn. I've created with the MAIN the prgCXC1250374_GENERIC_TH_R1KG001.rest file and with qamaker the quick_access_K610_R1KG001.vkp file.

2) I've choosen these firmware files because in folder anycid for K610 Model there are only 2 possibilities for executor.b file: R1KG001_CXC1250374_GENERIC_TH.zip and R8BE001_CXC1250374_GENERIC_TH.zip. The other files: customize_upgrade.xml and executor.jar have been taken form DB2020.zip.

3) Once flashed my phone with firmware files via oflash and settings db2020 port: DCU-60 speed: 921,600, i've turned off my phone, removed battery and inserted back again. Enter in far again with ofs option and settings db2020 port: DCU-60 speed: 921,600. This time for customizing copy files from K610_CDA_GENERIC_EUROPE_1.zip and files mentioned in point 2). Exit from ofs state and turn off my phone.

4) Put the sim card inside of my phone. Turn it on and i wait a little minutes while it is customized. After from games i run "executor". My phone turned off.

5) In the manual or tutorials say: "Put battery back and connect phone again on far manager but now chose script qb2020 so...use settings: qb2020 port: DCU-60 speed: 921,600 jump down and get into a large rabbit-hole. Connect phone pressing C (in my case is 2+5) after that u will get 2 options : bflash and bfs"

6) I've followed the steps (extracting sim card before). But when i connect phone using 2+5 in my case, far detect it, but inmediatly appear an error.

7) I've been reading qa2020.xml file. In CID52 header appears this:

<cid num="52" color="red">
<bflash>
<qhtry>2020_prologue</qhtry>
<run/>
<ldr>2020_f_R2A005</ldr>
<activateloader/>
</bflash>
<bfs>
<qhtry>2020_prologue</qhtry>
<run/>
<ldr>2020_cs_R3A006</ldr>
<activatecsloader/>
</bfs>

2020_Prologue, 2020_f_R2A005 and 2020_cs_R3A006 are files located in Far\Plugins\jdflasher\bin folder.

I don't know what is the problem. Could anyone help me?

Data from my phone: EROM R3A011, R1KG001, OTP CID49, FLASH EFECCTIVE CID52.

Thanks in advanced.
