Smartphones have become an integral part of life in 20 years. One device replaces a newspaper, a book, a notebook, a tool for work and a toy for entertainment. Imagine that all this data could be lost due to a critical error. Alas, a phone, like any device, is prone to break down. For example, recently people often encounter the Android error "encryption unsuccessful", which makes them wonder what to do in such a case.

What is this error

Before we move on to solving the problem, we suggest familiarizing ourselves with its peculiarities and causes. After all, it is better to know what you are dealing with, rather than acting blindly. In Russian, the error sounds something like this: "Android encryption failure". The thing is that the internal memory of the phone is encrypted with a master key, 128 bits deep. This is necessary so that viruses can not compromise files without the knowledge of the user. The encryption process is not as simple as it seems, and therefore it can sometimes fail. One wrongly shifted bit already makes it impossible to decrypt the gadget. In this case, the user will no longer be able to recover the data. But he can save the files that are on the SD-card. To do this, you need to remove it and insert it into another device.

Methods of elimination

After the card has been removed, we recommend that you try to restore the device's operation yourself. To do this, follow the instructions listed in the subheadings below.

Reset to factory settings

We assume that by this time the user has already accepted the data corruption, because now he will have to manually erase it by resetting the settings.

• 
  
• Turn off the phone.
  

• 
  
• Press the power button and volume down button until the recovery menu appears.
  
• Use the volume buttons to go down to "wipe data/factory reset".
  

• 
  
• Confirm the action. Some models require you to press the volume up button, some require you to press the power button.
  
• Confirm the reset again.
  

• 
  
• Wait for the process to complete and press the confirm button to reboot the device.
  

Firmware reinstallation

Alas, in some cases a simple reset is not enough. Due to a memory failure, the memory sector with system files is probably corrupted. In this case, you will have to completely reinstall the firmware. how to restore whatsapp backup to do this is written in detail in this guide. However, we still recommend that you entrust this matter to more advanced users. There are a lot of nuances in the process of flashing. It is better to master them on a working device than on a damaged one.

Appeal to the service center

If reflashing did not help, then, probably, the problem lies at the hardware level. In the internal memory of the device there are bit sectors that do not allow Android to start. In this case, contact the service center with a request to replace the eMMC memory. Such a procedure will cost 3500-4000 rubles, but not every master is ready to take on the job. Some even recommend in such cases to replace the board to which the memory is attached... In general, each case should be considered separately.
