For the machine with modified IMEI code, this command can restore the original body number. This instruction is also used for failures caused by program disorder in EEPROM (chip). Using this command will clear the phone book, so please use it carefully. *2767*7377# Unlocking the password reset command of mobile phone * 2767 * 927 # The WAP part is cleared, and the WAP setting crashes. I wouldn't have surfed the Internet. With this instruction, I can surf the Internet! *#8999*228# Battery parameter display, model/voltage/temperature *#8999*268# Change the boot country display in English (indicate the original sales place of water revision). *#8999*289# ringtone adjustment, ringtone frequency test/display frequency, up and down key adjustment *#8999*246# program parameter display *#8999*364# watchdog status display *#8999*377# EEPROM error display *#8999*427# watchdog signal path setting * # After displaying the latest time from this boot to now; Press->; After displaying the last boot time; Press->; After that, the last shutdown time and the last switching time are displayed. *#8999*842# Vibrator vibration test, up and down key adjustment speed *#8999*9266# display receiving channel number and receiving intensity indication *#8999*947# reset setting instruction *2767*3855# In case of major error, it can be used to identify whether the IMEI code of mobile phone has been changed by profiteers. The method is: first enter *#06#, see your IMEI code and record it, then enter *2767*3855#, then the mobile phone will restore the data in the Flash of the mobile phone to the EEPROM chip, and finally enter *#06# to see what the IMEI number of your mobile phone has become. If it's messy, it's different from the first time you recorded it, and it's different from the IMEI on the back of the phone, it must be a revision machine. If it is genuine, the IMEI seen before and after this method should definitely be the same. If you are a revision machine and want to change back the original forged IMEI number, you have to buy a data cable and get a software to change it back. Generally speaking, almost all board changers in the market do this. Don't just press *#09# of your mobile phone, because the password will be leaked, and some instructions such as *#0523# will be input by others. Some models of mobile phones need to be plugged in, while others don't. In addition, if the input is successful once and fails again, it is because of the memory effect of the mobile phone software. You can remove and reinstall the battery of the mobile phone and then try to input it (for example, after the command *2767*3855# is input, sometimes the mobile phone cannot be turned on without reloading the battery). But since 600C, mobile phones have been streamlined by Samsung, and many of them can't be used. You know that Samsung's 6 million universal password is 9998.
