Si no me equivoco, en settings debes marcar signed mode, enable alternative security bypass y enable preloader security bypass.
Debes tener el rest file y el bypass package. Si no los tienes, entonces primero debes flashear a una version soportada. Para generar el rest, solo debes agregar el Main que tienes, darle en signed mode y darle Identify.
Tambien necesitas una test SIM card o la SIM card de la operadora que quieres desbloquear.
Una vez que tengas todo esto, procedes a desbloquear con las instrucciones que el programa te va diciendo.

Este es el paso a paso de the_laser

Procedure of new alternative security bypass :

1. select correct phone model
2. go to settings tab,
3. check BOTH "signed mode (using server)", "enable alternative security bypass", that is required
Code:
if your phone is one next models
db2010 cid50/cid51
db2020 cid49/cid51
pnx5230 cid49/cid51
in order to enable NEW (STANDALONE) alternative security bypass,
you MUST check ALSO "enable preloader security bypass".
otherwise server-based security bypass will be used.
4. optionally, check "unlock after flash", "patch otp<>gdfs check in firmware"+"allow to change IMEI when unlocking" (read precautions)
5. optionally, check "complete phone after flash" (i recommend use custpacks)
6. go back to semc tab
7. if you need, add main+fsimage+custpack (script)
8. press desired operation
9. when asked, disconnect phone, insert TEST SIM, POWER ON PHONE FULLY and connect again.
Code:
when i say "POWER ON FULLY" - i mean state of phone,
when it shows main screen with operator name ("no network" with test sim)
10. HOLD "C" (or "2" for w880/simular) BUTTON ALL THE TIME UNTIL PHONE REBOOTS.
11. try to power on phone. phone must NOT power on. it is OKAY.
Code:
If phone power on, go to phone menu->games,
run "executor" application, go to step 11.
12. Disconnect phone, remove battery, insert battery, press "READY", then connect phone while holding corresponding button ('C' or '2' for w880). In 99% cases phone will reboot and connects automatically.
13. turn phone on and check it. delete "executor" from games to save user from regrets of running it.

Code:
after unlock in phone will be application called "executor"
(menu->games->executor)
it is leftover from unlock procedure, you should delete it ... or....
if you run it - it will install preloader in phone and then you able to do
any setool2 function without all that long steps...
(just check ONLY "use preloader security bypass)
phone will appear as "dead" for user in preloader mode
approximate time for unlock by patch using new alternative bypass method is 160-180 seconds on one phone.
