Step 1
To find out the firmware version of your Fly mobile device, use the special codes. Different phone models are suitable for different codes, but sometimes it so happens that the same code can be applied to many devices at once. Try entering one of the following combinations from the keyboard: * # 8375 ##### 0000 # * # 3598375 # * # 900 # * # 18375 #.
Step 2
You can also find out information about the firmware from the general system information menu by typing the combination #### 8375 #, be careful, this is available mainly for most old models. On special forums, you can also find out the versions of the standard firmware of phones related to a particular model. Please note - if you have already changed the firmware, information about it may not be available to you when using standard service codes.
Step 3
In order to return the Fly phone to the factory settings, also use the input of a special code from the keyboard of your mobile device: * 01763 * 737381 # In this case, all the system changes you made will be canceled, the system settings will return to the original ones. Before performing this operation, it is best to back up the phonebook data to the SIM card memory.
Step 4
Enter the code #### 1111 # to enter the Fly phone service menu. Be extremely careful when starting this mode, because without certain skills you can simply ruin the device. For some phone models, this menu provides access to additional settings that are not available from normal mode. Usually these codes are used by developers and service center specialists.
Step 5
Be careful when making a change using this mode, first find out from other users what consequences this or that action may have. Never change the sound level through this mode yourself.
