PLEASE TRY AT OWN RISK!!! I TAKE NO RESPONSIBILITY FOR YOU DAMAGING PHONE, UNLOCK CODES HAVE BEEN KNOWN TO LOCK PHONES UP AND THIS CODE HAS BEEN KNOWN TO DAMAGE PHONES BEFORE.The following unlock codes should work on most of these handsets (S/w Version Dependant) Sgh e100, e105, e700,e708, e715, p100, p400, p407, p408, s105 , s200, s208, s300, s307, s308, v200, v205, v206, x105, x450, x426, x427..& more
Method 1 (Example is meant for X426 Rev 1.5) -Insert Sim card for a carrier other then the one that your phone is locked to. -The phone should display either Incorrect Sim or Wrong Sim, now type *#9998*3323# -The LCD screen will go white and display an exit option. Now press the right soft key -The service menu will appear, highlight and select the malloc fail option, the phone will now reboot -Type *0141# and then press the send key (green phone button). “Personalized” will display on the LCD -Power the phone off, remove the sim and reinset your original sim card. -Turn on the phone and you will be prompted to enter the security code (review users manual unless you have changed the code). -Phone is now unlocked**Depending on your model the code in step 2 (*#9998*3323#) will need to be changed to a different number. Here is a list of other codes by model:Model: Samsung SGH2100 - *2767*3855# & *2767*2878# Model: Samsung V200 - *2767*7822573738# Model: Samsung SGH-E700 and Samsung SGH-X100 - #*7337# Model: Samsung SGH600 - *2767*3855# & *2767*2878# Model: Samsung A300 - *2767*637# Model: Samsung A400 - *2767*637# Model: Samsung A800 - *2767*637# Model: Samsung E500 - *2767*688# Model: Samsung C225 - *2667*688(15 Digit IMEI)# For most models that cannot be unlocked via code the next easiest way is with Data cable and software (this includes the above models with newer S/w Versions).
