Second, the type of Nokia software failure

Nokia software failure is broadly divided into three categories:

1 Please enter the security code (Securitycode)

    The security code is the phone's password , Nokia is an alternative design ideas . General other mobile phone manufacturers design the security code to prevent other non- legitimate users of the illegal use of the mobile phone handset designed , by the legitimate user to choose whether to start this function. Nokia researchers designed confidentiality , in addition to such use , the main role is on the phone when mobile phone users improper use ( such as dropped, the keys too hard , mobile water ) caused by software programs appear SCM system disorders, central processor does not recognize the right signals , to prevent users on the phone for further infringement , issued a directive to suspend the phone work, which is, " Please enter the security code " of the cause . If the infestation is further deepened, then a " contact service provider ." Also

    That is , the nature of software failure is a protective measure. In fact , there are similar protective measures , such as Motorola's handset appears in other brands of mobile phones , " Please enter the security code 8 " is also the role '(P1easeenterspecialcode).

This problem can be solved following three methods .

( 1 ) enter the original password to unlock . 8110 and early 3810 handset , the original password is random, and each phone 's IMEI code has certain conversion relationship . Late 3810 and 5110 after the mobile phone handsets , such as 6110,6150,8810,8210,8850,7110,9110,3210,3310 original password is 12345. Decrypted using this method to remember two points: First, Nokia appears " Please enter the security code " If you enter the wrong password three times in the fourth must be carried out in half an hour after boot, otherwise , even if the input the password is correct and can not unlock password. Second, if you have modified the password , such as 12345 into 67890 , when you do not start locking function appears Password " Please enter the security code " ( that is, software failure ) , then the password is not your modified after the 67890 , and has automatically restored to the original password 12345.
