Phone firmware is software that ensures the normal operation of the device. In order to change the internal appearance of the menu, as well as add or change the program functions and the menu language, they use a flashing. Removing the firmware can be considered as formatting the phone before uploading a new firmware, as well as resetting the phone to clear the memory and return to factory settings. In both cases, all personal information is erased.
Instructions
Step 1
In order to completely remove the firmware from the phone, it is necessary to carry out an operation similar to flashing, but use only those steps that are intended for cleaning the phone. Thus, you will need to synchronize your phone with your computer using a data cable and driver.
Step 2
Once you've synced your phone and computer, use the flashing software. Remove the firmware by saving it on your computer in case the new one does not work and you need to return the old one.
Step 3
In order to reset the firmware, you need a special code. Contact the manufacturer of the phone, asking him for the codes to reset the settings and reset the firmware. You may need to prove that you own the phone, be prepared to provide a cashier's receipt, passport scan, and phone serial number. After you receive the code to reset the firmware, enter it using the phone keypad.
