PPCGeeks - help me please to unlock t-mobile branded omnia

hello friends.

i am regular viewer of this forum(forum.ppcgeeks.com).

and i am bit fan of this site.

i am currently living in india.
and my uncle lives in uk.
he has bought samsung omnia 8gb t-mobile branded.

and i have followed the tricks to unlock via imsi / network code

which is this.
1) Download attached ZIP file

2) copy all three .lnk files to your PPC

3) run Lock.lnk

4) enter valid MCC/MNC of any carrier (I used my "real" SIMLock carrier ID, list: Mobile Network Code - Wikipedia, the free encyclopedia ; eg. 26001 for Poland, Plus)

5) As NCK, enter 12345678

6) tap OK (it should tell that SIMLock enabled)

7) run Status.lnk to see if its locked

8) run Unlock.lnk

9) enter code entered in point 5 (12345678)

Alternative method, works on i780, no copying of anything required:

- in 3), instead of launching .lnk, type the following code in the Phone app: *7465625*638*#

- in 7), instead of launching .lnk, type the following code in the Phone app: *#7465625#

- in 8), instead of launching .lnk, type the following code in the Phone app: #7465625*638*#

OMNIA I900

TRY THIS METHOD

Go to the registry, HKCU\System\State\PHONE, and wrote down the first 6 digits of the value of the IMSI entry.

1. type *7465625*638*# to set

2. type the first 6 digits of the value of the IMSI entry here.

3. type your new NCK (12345678), then OK

3. type *#7465625# to check your lock (Network lock still enabled)

4. type #7465625*638*# and type your NCK (12345678)

5. Enjoy !
