I don't know my phone code


Hi,

Try this steps , hope it will help you:

Unlocking:

If you have Rev 1.5 (x426) or earlier and most older models
Use the *#9998*3323# Trick (look for it on the forum)
The *#1111*WHATEVER# code will NOT work

If you have Rev 1.6 (x426) or later and most newer models
You MUST use unlocking software. Codes WILL lock your phone FOREVER

Locked: Return for Servicing

There is only 1 working solution, you must flash a copy of the firmware that is not in the locked status. (Most) Unlocking programs will NOT disable this issue, and your service provider cannot give you a code

If you do not plan to use your phone with another service provider, there is no real point to unlocking your phone other than to sell it. If you don't need to unlock it, don't take the risk of disabling the phone altogether

The *#9998*3323# Method:

1. If you have changed your phone password, change your password back to the default 8 zeros (00000000).
2. Put a SIM card that is from a network other than the one your phone is locked to
3. When Incorrect SIM error comes up, type *#9998*3323#.
4. White screen will appear with an exit option. Press the right softkey.
5. From the menu that appears, select the Malloc Fail option. This will reboot the phone and the normal service screens will appear.
6. Type *0141# and then press the green call key. "Personalization" or "Personalized" will appear.
7. Turn off your phone and put the original SIM back in.
8. Turn on your phone. You will receive a prompt to enter a password.
9. Type 8 zeros (00000000)
10. Completed. You have now unlocked your phone.

How to unlock your Samsung D900i


Make sure to back up all ur data and files, apps before performing these steps.


This will also bring the phone to default settings
1. First do a CUSTOM reset: *2767*2878#
turn off the phone
2. take out the battery and sim and put wrong network SIM and insert only a half of it,
Very important so it won't ask for network password and shows "Insert SIM" message.(possibly in a different language)
Now put the battery ,and switch the phone on .(phone shows "Insert SIM" message.)
3.push the sim fully in at this stage the phone is still asking to "Insert SIM"
4. Make a FULL reset: *2767*3855#
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#
7. Now Disable network lock By typing: #7465625*638*00000000#
Phone is unlocked

Just thought this may be useful for someone,

Resetting the phone will erase everything on your phone, if you agree to reset it please follow the steps below:
  1. Please remove the sim card on the phone.
  2. Place the battery back in without the sim card.
  3. Enter *2627*3855#, wait until you see “Insert Sim” message, then place the sim card back in. Hope this will work, but if not the phone needs reflash.

I forgot password on samsung sgh j210.. it as


Hi,
Please follow the instructions carefully but if the code fails to work, then ,make no more than 4 attempts as it may lock your phone. Can you let me know how you get on with it as well please. Thanks. Please also make sure that you back up any information on your phone as in certain cases the resetting also removes your contacts from the SIM and your pictures. j700 unlock method Basically the SP lock needs to be removed before the Network lock is disabled, so if you only have SP lock on, you need to turn the Network lock back to active, disable the SP lock and then disable Network lock. A reminder 'how to' is below: Do a custom reset: *2767*2878# once this has finished rebooting turn the phone off. Next a SIM card from a different service provider needs to be pushed half in - (Push it fully in then slide it back out by about 1/2 a centimeter), Turn on the phone - you will now see an "Insert SIM" message, Now perform a full reset: *2767*3855# When the phone powers off, quickly push the SIM card fully in, and let the phone power back up. After you do the reset, check and make sure that your Network lock is active by pressing *#7465625# If it isn't active you must use this code to reactivate it: *7465625*638*00000000*00000000# Then you have to deactivate the SP lock first. To do that you need to input: *7465625*77*00000000*00000000# (this will reset the lock) Then you enter: #7465625*77*00000000# (to disable the SP lock). Then you disable the Network lock: #7465625*638*00000000#

Cracking a PUK Code?


Pin Unlock Code (PUK)
If you miss key (or forget) your SIM pin code, and enter the wrong one 3-5 times in a row, the sim will lock up, and you’ll need to enter the PUK unlock code to release it. You should ask your Network Service Provider for this code when you need it. Don’t try to guess it, because after a few wrong guesses, the SIM card will be permanently disabled.
