Samsung SGH-C450 Unlock Code

[hamboneone23954]

HI, can anyone tell me how to unlock a Samsung SGH-C450 locked to Telstra Australia.
I have tried generic codes that I found on this forum but they do not work and it now tells me that I only have 4 attempts left to unlock.

IMIE No is 358566018147692

I appreciate any help.

Thanks

Ok check this:

Without simcard, phone powered on press *#7465625#

If only the Network lock is active then follow this next step

Insert half non-accepted sim in the phone, you should manage the battery in such half inserted way so that after power on the phone, when the phone say's "INSERT SIM" you can still put the simcard in its place. At this time, fully insert the sim.

Now.., do full emprom reset *2767*3855#

Phone will restart and accept the inserted simcard.
Now you need to reset the Network lock to 8x0 by entering *7465625*638*00000000*00000000#

To take Network Lock out enter #746525*638*00000000#

Enjoy....!

If phone has more locks active, then I can not help you further

Hi Daimond,
I followed your step. After full eprom reset, the phone restarted and accept the simcard then display "Phone freezed" and ask to enter password.
Any idea? thanks

Hi Daimond,

Thank you Black_Daimond!

I have created an account to say thanks for this post. I have just unlocked my old Samsung C450 following the steps from above.

I had only Network lock active so it worked just fine.

So the conclusion is that this method WORKS!
