Codes, Hacks and More!!! For Your GSM Phone!!!Sep 21 '03 (Updated May 21 '05) Write an essay on this topic.The Bottom Line These codes are not guaranteed to work for your phone, unless it is the Nokia 6200 or the Nokia 6800. Try these at your own risk! I've been browsing the net trying to find different codes for phones. I've succeeded in finding alot, but some of them I don't understand. If you know what it means, then please reply! Most of these codes should work with any GSM cell phone, but some of them are Nokia exclusive. While these codes are intended for the older phone models, all of these codes have worked for my Nokia 6200 and my wife's Nokia 6800. These codes are intended for DCT4 phones, in other words, the Next Generation phones. Show IMEI number. Of course you can just take off the battery, but if you don't want to, then at the stand-by screen, enter this: * # 0 6 # To change your PIN number from the stand-by screen, you'll need to know the old PIN. Enter: * * 0 4 * (old PIN) * (new PIN) * (new PIN) # 1. Push the "Star Key". 2. Push the "Star Key". 3. Push the "0" key. 4. Push the "4" key. 5. Push the "Star Key". 6. Enter your old PIN. 7. Push the "Star Key". 8. Enter the new PIN that you want. 9. Push the "Star Key". 10.Enter the new PIN that you want again. 11.Push the "Pound Key". To change your PIN2 number from the stand-by screen, you'll need to know the old PIN2. Enter: * * 0 4 2 * (old PIN2) * (new PIN2) * (new PIN2) # To change your PUK number from the stand-by screen, you'll need to know the old PUK. Enter: * * 0 5 * (old PUK) * (new PUK) * (new PUK) # NOT CONFIRMED!!! TRY AT YOUR OWN RISK! To change your PUK2 number from the stand-by screen, you'll need to know the old PUK2. Enter: * * 0 4 * (old PUK2) * (new PUK2) * (new PUK2) # NOT CONFIRMED!!! TRY AT YOUR OWN RISK! The Following Codes Will NOT Work For The SONY Ericsson T616, and I Assume That They Will Not Work For Any Model of SONY Ericsson Cellular Phone!!!!! To check the Firmware version on your phone, enter: * # 0 0 0 0 # To turn on the EFR, enter: * 3 3 7 0 # After you accept it, the phone will turn off. To turn the EFR off, enter (the difference is you start with # instead of *): # 3 3 7 0 # After you accept it, the phone will turn off. This is what the webpage that I got the code off of explained about the code: "EFR (Enhanced Full Rate) Codec will be activated after a reboot of the phone. EFR produces superior (near-landline) voice quality if supported by the host Network" To turn on the HR, enter: * 4 7 2 0 # After you accept it, the phone will turn off. To turn the HR off, enter (the difference is you start with # instead of *): # 4 7 2 0 # After you accept it, the phone will turn off. This is what the webpage that I got the code off of explained about the code: "HR (Half Rate) Codec will be activated after a reboot of the phone. HR (if supported by the host Network) offers better battery talk time but produces inferior voice quality." To view the warranty screen, enter: * # 9 2 7 0 2 6 8 9 # The only way to get out of this screen is to turn your phone off. To reset your phone back to the Factory Defaults, enter: * # 7 7 8 0 #  |
