SOURCE: 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#

I have samsung sgh-e830 i put a password on my TM sim but i forgot the password. i cant use my phone everytime i will put another sim card. how can i fix this problem? thanks


That password is not easy to get passed without the correct one. You will either have to jog your memory or arrange to send it to Samsung. You'll likely lose what you've stored. (don't hate me as the bearer of bad news).

2 - Don't bother about what's being displayed on your Samsung SGH-E480,
3 - Compose : #0111*unlock code#.
That step should be make your samsung unlocked. Good luck and have a try!
