What if Samsung note3 fails to update the firmware of the mobile phone?

Samsung detected this problem not because the latest Android 4.4 KitKat version does not support third-party accessories, but is just a system bug.

If you are sure that your problem is not a system bug, we can refer to the following methods to see

1) The first possibility is that the network data is not smooth. We recommend that you upgrade the network to a better position. Or use wifi to download the firmware.

2) The second possible cause of an update failure is that the battery power is insufficient. This is the last small cell phone, the power is not enough, the update process is infinite restart, so be sure to ensure that the battery power is sufficient during the update.

3) some of our friends cannot be updated after root. If you are sure you want to update the firmware, restore the factory settings and then download the firmware again!

4) the last possibility is that we are too worried! It takes some time to update the system. We need to wait patiently. In addition, do not press the other buttons on the phone when updating!
