Unlocking z710i

[miki75]

Hi friends,
I have been searching for a long time how to unlock my phone z710i and be able to use it in Europe. It has 2 locks with Fido, Canada: Network and SIM and since they don't provide the NCK code and SPCK code I was thinking for another way to do it.
Personalize Menu: <**< : Network & SP
Service Menu: >*<<*<* : Service Info/SIM Lock: Network & Service Provider

So, looking and reading I am getting confused what can be done. I have tried:
1. SEtool2 Lite v1.11:
Identify... works ok: Network: LOCKED... Service Provider: LOCKED. Operator Multiple.
Reads GDFS, makes the .bin file. So far so good.
When I try to FLASH with 'Bypass security DB2020' I get the message:

... ... ...
LDR: 061201 1314 HAN..._DB2020_FLASHLOADER_R2A005
Flash ID check:2019
Flash props sent ok
phone CID not supported in that mode

??? and it says that it supports DB2020 CID 49/....???
Any ideas why its not working?

2. anyCID too but... they don't have executor.b for MAIN_NAM_1_CN_RED49 which I have on my phone... its only for the GENERIC, and as far as I have info this I have to find executor.b for my firmware, otherwise it will brick the phone.
Any ideas here?
Do I have to use GENERIC in order to have the phone unlocked ?

3.XS++ 3.1

11:50:39| Profiling SEMC phone...
11:50:39| Platform: DB2020
11:50:39| OTP CID: 49
11:50:39| EROM CID: 49
11:50:40| EROM Color: Red
11:50:40| IMEI: 35306501xxxxxx
11:50:40| Phone ID: Z710
11:50:40| Region: ROGERS
11:50:40| CDA: CDA102651/18   R7A
11:50:40| Firmware Version: R1EF001
11:50:40| EROM: R3A016

I have for that firmware files MAIN_NAM & MAIN_GENERIC, FS, and CUSTOM (Fido) so I was wondering if I flash the phone with XS++3.1 will that solve the problem?
XS++ asks for upgrade to CID52... will that improve anything?

please, help me with this.

Thanks for all the guidance.
