Hello, there are many reasons, you can take a look at it below:
1) The easiest: Since every flash phone does not do a full erase, this leads to some configuration confusion. Workaround in this form:
Erase all storage formats. such as "file2 system".

This is a software issue and the software must be upgraded.
3) Reboot due to mismatch between hardware and software.
Check the relevant spec and product information to see if the software supports the hardware version.
4) At the lowest level, the process of software flash is not right. )
In addition, such as operation error, poor contact of mobile phone card, weak signal and unstable current and voltage. But this is only some external reason, not a real reason.
