Unlocking code for a Samsung SGH-D900

hi folks,

I have a d900 locked to orange does anyone know what the code might be to unlock it so i can use it on t mobile?

thanks

Hi,

I suggest u're better to get your local shop to unlock it

Because some "unversial unlock code" on samsung will wipe out all imei and set it to 0000

Hello,

I can confirm this has worked on a d900 and on a e250 for me personally. But use at your own risk. (also.. this DID NOT do anything to IEMI code.

1. First do a CUSTOM reset: * 2767 * 2878 # (star 2767 star 2878 hash)
turn off the phone
2. take out the battery and sim and put wrong network SIM and insert a HALF of it, ie half in and half out and slip the battery in behind it, this is important
so it won't ask for network password and shows "Insert SIM" message.
Now put the battery, and switch the phone on. (Phone shows "Insert SIM" message.)
3.With out turning off the phone push the sim fully in. At this stage the phone is still asking to "Insert SIM"
4. Make a FULL reset by typing: * 2767 * 3855 # (star 2767 star 3855 hash)
5. The phone should reboot working with "wrong" sim inside.
6. Make a Change the NCK password to 8 zeros by typing: * 7465625 * 638 * 00000000 * 00000000 #
(star 7465625 star 638 star 8zeros star 8zeros hash)
7. Now Disable network lock By typing: # 7465625 * 638 * 00000000 #

hi, thanks for posting this. it worked great on my samsung sgh-d900.

unlocked from voda to orange. spot on.

thanks

Great! Worked like a song! Thanks very much!:thumbup1:

Thanks v much for this.

I had just bought a D900 from EBay, that claimed to have been used on O2 (which was what I needed). In fact it was locked to Orange!

Your instructions worked just fine, though it was quite difficult pressing those keys with my fingers crossed!

hi guys. I tried to follow the guide to the letter.
Where i get stuck is after the reboot.
What it does is, it comes back to the screen where it says what phone it is and then it doesnt go anywhere from there.

Any help?

The part of "make a Change the NCK password is a bit elusive to me. Anyone who can explain it?

Cheers

It baffled me a bit as well, but I just followed the instructions exactly without necessarily understanding why I was doing each of the steps.

I guess you've got nothing to lose by starting again from step 1?

Hopefully the originator of the advice will be able to give you a better explanation.

Hi mate. I've tried to start all over again. Which it allows me to, however, at the same point ( after the reboot ) it comes up with the phone name. SHG-D900, something, something, and doesnt move away from that.

what happens when i then turn off and then on the phone is that it asks for pin code, and after that a network code. That i dont have :)

Hello there, it is suggested and is better if you take your phone to the authorized service center, since they will surely know how to get rid of the issue.

i need a bit of help.
My d900 as some kind of problem that the screen light doesnt turn on, this only happens some times.
its it possible to reboot the all system.
i belive that it is a software problem.
