Without sim unlock, this phone is just a brick of mine...I am not with at&t...

illmac · Oct 5, 2011

so you went out and bought the phone without a guarantee of a working unlock?

ljwnow · Oct 5, 2011

Exactly ...

Sent from my SAMSUNG-SGH-I777 using xda premium

Did Not Work

Ok, I had my SGII rooted with the ClockworkMod.Tar thru Odin3 and SuperoneClick. I also OC using Odin3 with galaxysii_OC_V1.tar thru Odin3 again and install setcpu..

I ran this unlock, but it never reboot, so I manually rebooted and check using the dail pad (from post here), and it says that I'm still lock.. I try it a second time and it did not work either..

Any Help will be appricated.. Also, my back button also does not work anymore. My Home button now acts as a back button.. anyone have this problem??

First make sure your superuser is working. As far as I know, there is no kernel for At&t GS2 that supports OC. Am I out dated?

Superuser is working I just check.. and now i have other problems. I now can not hear any sound nor the reciver of my call can hear my voice... the call goes thru but it's like everything is muted???

Sky, do you have the AT&T Galaxy S2 or the international version?

MisterEdF · Oct 5, 2011

Wow, whoever did the spell checking for Samsung really screwed that one up!
