Hello, I really like this forum and all specialist here and I want to ask something. I want to know how can check Nokia 1100 rh 15-16-17 real software version I found some hidden codes but do you know something I can be sure what is factory defaults on this phone. This is what I have To enter in the secret menu in Nokia Phone. On the main screen type *#92702689# [*#war0anty#] It will take you to a secret menu where you may find some of the information below: 1. Displays Serial Number. 2. Displays the Month and Year of Manufacture 3. Displays (if there) the date where the phone was purchased (MMYY) 4. Displays the date of the last repair - if found (0000) 5. Shows life timer of phone (time passes since last start) To restore Factory Settings for Nokia mobile *#7780# reset to factory settings. Greetings and thank you for helping
