ROM Toolbox Pro is a premium version of the system utility.
If you still decide to flash your phone and get ROOT access, then you just have to download this application. With its help you can make a huge number of things that are not available to ordinary users. Your phone will be faster, more beautiful and clearer. You can change everything from its appearance to the CPU frequency setting. If you do not want to change anything, but just want to know the details of your hardware, then use AIDA 64.
Capabilities:
Backup and recovery of all types of data, including SMS, logs, applications and media files
After the download is complete, the downloaded file will be displayed in the notification shade (top), and will also be located in the "Download" folder (any file manager )
Install the downloaded APK file using any file manager or by clicking on it (on the downloaded file) in the notification shade
If you are installing apps for the first time not from Google Play (but using a file manager or browser), you will need to grant the appropriate permission. This is done only once.
If the file was downloaded with the bin extension, then there are 2 options:
Change the extension of the downloaded file to apk using any file manager ("rename" function)
To update the application, install the new version of the application over (without deleting) the old one.
This update will only be possible if the previous version of the application is downloaded from us. Otherwise, there will be a signature conflict and you will see the message "Application not installed".
For what "Signatures" are and what they are for, read here.
