I had restarted the phone and it is asking for a sim network unlock pin. how can i get that pin?
Did you report the post yet? You have a different phone and carrier to us so we can't help you

Hey, i can only use the simcard i buy with my telephone. If i flash my rom to a custome firmware. Can i then use any sim card?
No. Simlocks are not touched by firmware so it will remain locked. The only way to unlock is by contacting your mobile phone operator or by using the paid web services.

Hi,
I have a LG P769 from TMobile, how can I use this phone without a tmobile sim card but from another company like my brazilian sim card?
Can I flash other rom instead of p769? Will it work?
I was reading this topic
http://forum.xda-developers.com/showpost.php?p=40691384&postcount=7
here says to unlock bootloader with a P765 first. So, can I stay with this rom?
Thank you.
If it is a prepaid phone the alternative SIM may work. Try putting it in. See what happens. You don't need to unlock the boot loader to unlock SIM. Worst case scenario if it asks for an unlock code, power off the device then either contact T-Mobile if there isn't a contract on the phone to get an unlock code or look up SIM unlock online to get unlocking service.

Thank you for the answer, I input the network unlock code and the phone works with any carrier now.
But how can I remove all the tmobile bloatware this phone has? Can I change it to a international unbranded phone?
Check out the v21b (Canada version) wind mobile. It's a nice clean Rom. So much better than the T-Mobile jelly bean

Root it and download a root unistaller to get rid of the bloatware.

How do I flash this rom? My phone is a p769 10g. Is it easy?
Flash the kdz file or the cwm rooted file in the other post called nandroid backup files in the general area.

Don't post your imei on the internet, you may find it will never work again.
Go buy an unlock code, nothing else works.

Agreed!
I have flashed my Verizon S3 to Omni KitKat 4.4.3 version. I am thinking Bootloader is locked means it will unlock this SIM too.
If not how to unlock the SIM to use other carrier. Is there any app for unlock the phone?
Wrong forum, this is for the i9300 only.
