How do you reset the phone lock on samsung Sgh-F480?

Na-try ko na po itong steps sa baba (wrong passWord lagi.)

1. You must first do a reset CUSTOM: * 2767 * 2878 #

2. Take a rejected SIM card (which the phone wont accept) and insert

while the phone is switched on, without removing the battery.

3 - Make: * 2767 * 3855 # (Reset the notebook)

The phone should turn off within 1 minute,

4 - The mobile accepts the sim card, but if it holds, the phone is always locked (no network).

5 - Now, do: * 7465625 * 638 * 00000000 * 00000000 #

The unlock code is 00000000, now.

6 - Enter *#7465625# and watch what is Active.

* If the PC lock is On, make # 7465625*27*00000000#

* If the lock is Active Network, to # 7465625*638*00000000#

* If the SIM lock is On, make # 7465625*746*00000000#

* If the SP lock is On, make # 7465625*77*00000000#

* If the Subset lock is active, the # 7465625*782*00000000#

temporary....will go back if switched off
