The mobile phone can be blocked for various reasons. To unlock the system, you first need to turn on the device and check for operability.
Instructions
Step 1
As a rule, most telephones are blocked together with a USB flash drive. This can be done automatically or by user command. In this case, the main memory of the phone is also blocked. In such cases, you need to enter the set password. If you don't know the combination, try the standard ones: 0000, 1111, 1122.
Step 2
It is also worth noting that mobile devices are blocked under the influence of third-party programs. These can be both standard functions installed in the program, and viruses that got into the phone's memory by downloading the utility. To remedy the situation, connect the phone to the computer using a special cable and check with antivirus software. Scan not only the phone memory, but also the extra space.
Step 3
The phone memory may be blocked due to the SIM card. Let's say you are asked for a pin code when you turn it on. If the combination is entered incorrectly several times, the card is automatically blocked. To unlock the system, you need to use puk-codes, which are usually indicated in the documents from the SIM card. Try to enter all the numbers correctly, as you can permanently lock the phone.
Step 4
If all else fails, take your phone to a dedicated service center. All problems will be solved there within a few minutes. It is also worth noting that in some cases it is necessary to reflash the mobile phone system. If you do not understand anything about this operation, it is better to take it to a special center to solve the problem. As a rule, independent actions can completely "kill" the device.
