Im sure this is the General Section... This is a Question OP
You want to unlock your phone from the 3 Network? Not surprised
Have you tried other sim cards already?
My name is Optimus Prime and I send this message..

No it simlock. I wanna unroot it. I was wondering if I can install the stock simfree firmware not the stock 3UK back on it. .ir the Asia line stock firmware will it make the phone simfree ??

You do not need root to flash a stock firmware.. if you want to unlock your phone from your carrier, i suggest you root your phone AFTER you flashed a stock firmware.. there are applications here in XDA that does the job neatly.
I hope this helps
Thanks!! My phone is already unlocked so i do not need root

it is branded, i got some carrier specific apps,and also the bootlogo of the carrier,a french one( bienvenue or something like that).So it must be sim unlocked if i am using orange...
once you sim unlock the phone, it should not sim relock when you flash a unbranded firmware through odin. I hope i answered your question

Factory unlocked sgs3 JB update

Hey guys I have a factory unlocked phone which I bought from china, and I also have it rooted, my friend wants me to to update to JB but I'm not sure if I have to unroot my phone to get the update and also if I unroot it will I loose my factory unlock? I'm using it in the United States right now. With carrier t-mobile.. I've also seen other posts about being slow after updating if it's international so what should I do?

[Q] Can I use another sim card in the P769(TMobile)?

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.
