IMPORTANT: Unlocking and Phone Locked Return....

This is to clear up all the posts and ongoing emails on Unlocking, whether to change services or just remove "Phone Locked" messages.

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.

Cerebros Instructions:

1. Make sure phone is plugged into cable, cable is plugged into computer, drivers are installed, and phone is on.
2. Start Cerebros Unlocker 1.5
3. Click the "Models" drop-down box
4. Select your model from list (q100 = x426/x427)
5. Press Unlock
6. Wait until finished and unplug phone
7. Remove battery, replace, and turn phone on
8. Phone is now unlocked

WinIMEI Instructions:

1. Make sure phone is plugged into cable, cable is plugged into computer, drivers are installed, and phone is on.
2. Start WinIMEI
3. Make sure U.S.A. (Voicestream), A Line, 1 PC, and the com port you are using are selected from the appropriate drop-down menus.
4. All selection boxes should be unchecked
5. Click Write IMEI in the bottom center
6. From the new screen that appears click RD IMEI Setting
7. Wait for TestModeOn Pass and the box in the upper right to display Pass and turn green before proceeding
8. Click UnLock from the button cluster in the bottom right
9. Click both Exit buttons and disconnect phone
10. Your phone is now unlocked

Note: All previously listed programs and an unlocked version of the x426 rev 1.6 firmware and optiflash (for flashing it) are available at my site: http://www.personal.psu.edu/sjs342/Midnight/index.html

somebody sticky this

Sgh e100, e105, e700,e708, e715, p100, p400, p407, p408, s105 , s200, s208, s300, s307, s308, v200, v205, v206, x105, x450, x426, x427..& more (new vers. not supported)

1. Turn off your phone, put in a SIM of a provider that it is NOT LOCKED
(difference company's SIM card) to, and turn it back on.
2. At the wrong card message, type *#9998*3323#. A message will pop up telling you to press exit,
so hit the right soft key. Choose number 7 . Your phone will
reboot and your SIM will work.
3. Type *0141# and then hit call. This will give you a message saying your phone is personalized.
4. Power down your phone and insert a SIM card other(another company) than the one that is in it.
Then power back up your phone.
5. At the SIM pass code prompt type 00000000, that is 8 zeroes. So that will totally UNLOCK your phone.

Some of the other codes listed (besides 3323) can damage your phone.
Also, Not every phone is capable of the 3323 method and there is no guarunteed way to unlock these phones using codes alone.

Good job. Yet another reason this post was created. First, you forgot to mention a couple of details about the password. Second, the other codes are not guarunteed to work. Third, you don't need 3 sim cards to completely unlock. Thanks for trying, but if you don't plan to clean up... don't make the mess. I am tired of getting 5 different emails a day saying "I saw your posts and your (some random complimentary word, ie. amazing) site and was hoping you could help me. My phone says Locked: Return for servicing. What do I do?" because people post faulty unlocking codes. It's not the fault of the person using the code, either, it's the fault of people like me who know them not fully explaining what they do or how they are used. That is why this post is here. It is meant to help clean up the mess before it gets bigger.

I tried to unlock my phone and got that message, I thought it was locked for good but i found a code that works (*#9998*533#) enter it and select 6 the phone will reboot and your chip should work

my problem now is that when i use a chip from a nother provider it displays service limited and i cannot make any call though i can view the phone book and other setting on the chip. my location is jamaica and bothe companies are in jamaica i dont know if it is the frequency and how to check / chanke it.

will this work for rev 1.7. also i cant backup my damm rev using optiflash. it just stops after saying hit on off button. i do it and nothing happens. its my dads x426 and he wants to keep his same number. so i need to unlock it. but the software wont back it up.

Just use cerebros unlocker and you will have your phone unlocked. No back-up is needed.

the X426 wasnt an option on the drop down menu. do i just type it in?

q100 = x426 with cerebros

Please post how to get rid of Limited Service error after unlocking samsung mobiles.
