Warnings and Precautions

  • do not forget that sometimes recommended a full reset (format) , so as not to bring the tails of the previous firmware.
  • Download the correct firmware (all links are in the header of the theme of your phone).
  • Please Note that even though this statement is essentially universal, but it is subject to MX4 and when you go out of your order on your device, then keep in mind that the files must be taken from their phone model and not on the MX4. The same is true if you do not understand something and you ask questions about the topic. Do not forget to return to the theme of your phone.
  • Strictly abide by the name of “update” and extension “.zip”, If the name is not correct in recovery see the words “Firmware not found”.
  • Do not forget to check the integrity of the file. Note that even MD5 checking the firmware file there is a theoretical possibility that when you copy a file to the phone will not be copied completely.It is better to once again verify the MD5 on the phone (unfortunately does not work in the 3rd version of the installation because the file is temporary and will be deleted as soon as we come out of rekaveri, but on the computer after copying to the folder G:\Recovery, we can still check MD5) . MD5 can synchronize the phone also using various applications. I have been using Solid Explorer File Manager.

Notes :

Undo / downgrade (Eng. Downgrade)
Downgrade (to return later to an earlier version of the firmware) is possible by any embodiment of the above.
The main thing is that the process of transition to a newer firmware (for example, 4.5.2) to older (for example, accompanied by data cleaning. In any case, I recommend the third option. And there is a solution for you.
There are certainly exceptions for rollback. The logic is not revealed until the end, but overall will zoom through the very first firmware. Those. in fact roll back is possible through preset at the factory firmware. For example, a plant stood firmware 4.0.3, the rollback will be done through it. The difficulty lies in the fact that sellers are often the factory firmware is reset, and then have to choose the firmware manually.
