Nowadays, many people like to use tablet computers, but during long-term use, the tablet computer will suffer from a series of freezes or other failures due to its own insufficient buffering, or due to problems we use. Therefore, In this situation, many friends will choose to flash their tablets, so what I will introduce to you next is the flashing process of Lenovo a2207. Friends who want to flash their phones can come and take a look.

Preparation work

Before flashing, we need to make a series of preparations. First, we need to check the memory. Whether there is a problem with the card and whether the capacity can meet the requirements of the flash package, then check whether the phone's power is sufficient. Generally, during the flashing process, since it cannot be charged and it lasts a long time, the power should generally be kept at 50 % or more to avoid flashing failure in the middle. We download the flash package from the Internet. Generally, the format of the flash package is jpg. After downloading the flash package to the computer, then copy and paste it to the mobile phone. Next we will start the official flashing work. First we need to shut down the phone, and then during the boot process, press and hold the power button and menu button of the tablet at the same time, which will automatically enter the developer mode.

Data backup

When entering the developer mode, there will be a series of selection menus and we choose to restart the system. Restarting the system means that we have to clear all the data and cache in the original phone, so before flashing the phone, we must back up the important data or contact data in the phone to another memory card and upload it to The cloud can also be used, and the step of restarting the system is very important, because if we do not clear the cached data in the original mobile phone, then if we re-enter the new system, the data structure will be changed.The difference causes the system to fail to start after flashing, so we must be prepared to restart the system before flashing.

Official flashing

Then we use the cache clear function to ensure that the cache data is completely cleared. Guaranteed not to miss anything. Then we install the flash package into the tablet, select it in the menu that pops up again, and select the flash package from the SD card. At this time, the tablet interface will automatically display the file list for flashing. At the same time, we can also see the flashing package just placed in the memory card. In this step, we need to select the flashing package file we just copied and select it. Click OK later. After confirming the flashing operation, the system will automatically perform the flashing operation, which usually lasts for about ten minutes. We must not shut down the machine at this time. When the flashing is completed, the system will automatically prompt that the flashing is completed. We are also told to restart the system, and since the system takes a long time to start during the first restart, we need to wait carefully.

The above is the introduction of the Lenovo a2207 flashing tutorial compiled by the editor. After the above explanation by the editor, I believe that everyone has a clear understanding of the flashing process of Lenovo mobile phones. In fact, the flashing process of all mobile phones is similar, and what needs to be noted is that we must choose a suitable one for our mobile phones. Do not download files containing viruses or Trojan horses when using the system's flash package. If flashing fails, we can also follow the steps explained above and try it again.
