What if the signature of the update package is inconsistent with the installed application? ? The solution is as follows:

1. You can download back the same version of the software and uninstall it together with the data when uninstalling. Note that the data must be uninstalled together and cannot be retained.

2. Download and install MT Manager, find the latest installation package file, press and hold the new installation package, select signature, and install the signed installation package (new signature installation package) after signing.

3. Handle the suggested operation according to the installation failure page.

4, double clear or restore the factory settings.
