Blocking of Samsung phones is used to prevent a different operator from the original one in the network, as well as to protect the owner's personal data in case of loss or theft of the mobile. In the first case, the code is requested when you turn on with a SIM card of another operator, in the second case, when you try to access private information stored on the cell phone.
Instructions
Step 1
When blocking the phone for a specific operator, you must enter a code that allows you to use the SIM card of a "foreign" operator. The operator can provide this code, you just need to provide the IMEI number of your phone for verification. You can find out the IMEI number of your phone by dialing * # 06 # on the keyboard. You can also find it by opening the back cover and removing the battery. Enter the received code, otherwise a flashing will be required.
Step 2
Synchronize your phone with your computer. To do this, you need a data cable, as well as drivers and synchronization software. The best option would be to download the necessary software components from the official site - www.samsung.com, otherwise use a search engine and download drivers and software from one of the Samsung phone sites. The software can be for the entire model series to which your phone belongs, but the drivers must be specific to your model. You can buy the data cable required for synchronization at a cellular hardware store. Install software and drivers, then connect the phone to the computer and make sure that the program "sees" it
Step 3
After synchronization is complete, download the firmware, as well as the firmware update software from Samsung fan sites, such as samsung-fun.ru or samsung-club.net.ua. The best option would be to download the firmware, which is "factory" and has no traces of extraneous interference. Be sure to copy all personal data before starting the operation, otherwise they will be lost. Make sure your phone battery is fully charged and flash your phone exactly following the instructions.
Step 4
If you have blocked your phone with a security code and forgot it, contact Samsung technical support, whose contacts you can find on the website www.samsung.com. Provide your phone's IMEI and serial number, then request a firmware reset code and a factory reset code. Keep in mind that resetting the firmware will erase all your personal data, so use it only as a last resort. If for some reason you are not provided with these codes, update the phone software using the second step of this manual.
