[Q] T-999 T-Mobil Network Unlock
a year ago i bought a S3 from T-mobil in the USA. Now i want to use it with a different carrier and called for an unlock the support for an unlock code. After 6 Times calling and more than 3 months waiting i now try to find another to unlock the phone.
My problem here is not that i can't find information, it's that is so much information.
So i got a t-999 S3 on 4.1.2
I want to get botherd by those tecnical things as less as possible, and don't need the root if it's not nessesary.
ALso i don't need all those T-mobil apps that are pre installed.
(easyist Option?) downgrade to 4.1.1 with odin and unlock with the servicemenu (UMTS-Debug...)
(where can i find the "stock" 4.1.1 and where the upgrade and afterwards can i normally upgrade?)
everybody says easy as pie but I'm not so sure)
a) Rooting the device and put with odin CF-Root-SGS v6.4 on it (it sounds like a generic s3 version without tmobil cr*p so maybe without the lock and the apps (if yes can i normally update afterwards?)
b)rooting it like in this video http://www.youtube.com/watch?feature...&v=QPeIZZVYHbY
and installing an unlock app?
(like this http://forum.xda-developers.com/showthread.php?t=761045
c) rooting it with this wierd auto CF things
What do you thing is the best and cheapest
way to to that.
(And maybe some help here ->noob)
Thank you for you time Gentleman
