Hi,
The lt18i should be used with euro frequencies
Unlock changes nothing excepts sim lock check.
So find the reason

[meisam]

Anyone knows how to change the band frequency?

I did flash the phone with 2.3.4,and did the unlock again via TP and 4se dongle.Now it detects the network but can't make calls.Any idea?

Hi, im a beginner on SE phones, i have here a customers phone..
Its LT18i, its produced 12W19, it shows signal bars, but it ask for network sim lock PIN, i presume that its locked, dont know the origin where its from..

Its running on android 2.3.4, works perfect...
What are my chances to get it unlock, since i dont have any Box for the moment..
Any help will be grateful.

Thanks in advance....

Hi, about this bypass TP, it is difficult to be done, cause i dont understand it...
I saw the instruction how to make Test point, but what is precisly, can it be unlocked whith this procedure or what ?
Since is 12w19, can i bricked it if i try...
Its a customers phone, it will be nice to get it unlocked, but cant risk to damage, cause its a gift from someone to him, and when are gifts in question, cant handle specially not in my country...

Sorry for my amateurs questions, but new on other phone repairing, just apple devices working long time...

Any help will be grateful...

Thanks..
