SGH-T429 Unlock
For future reference…
- Insert a different carrier’s SIM card.
- Turn on the phone (Result: Should say “Wrong Card” on the screen)
- Enter *2767*3855# on the keypad and wait for the phone to restart itself
- Enter *7465625*638*00000000*00000000#
- Enter #7465625*638*00000000#
- And for confirmation enter *#7465625# (Result: Everything listed should output “Inactive”)
You may not see any confirmation for steps 1, 3, or 4. I tried this without a SIM card and it wouldn’t let me do step 5 (which is the actual network unlock).
