We read Backup from the phone’s memory. We save it in a safe place.
It can be useful in case of unforeseen situations.
To restore the backup to the phone, the hidden Write Memory function in SP_Flash_Tool is used.
(To activate the write memory function, you must press the key combination "Ctrl + Alt + V" in the program.
Advanced Mode) should appear in the title bar. Details there -
SP_Flash_Tool is the flash driver for MTK smartphones.When restoring a backup without user data and cache, you need to go into the recovery and do wipe data / factory reset.
Without this, the phone will not boot.
If the program generated an error, then disconnect the phone from the computer, click "Read Back" again and connect the phone.
Sometimes it helps to connect the phone without a battery or with the volume button + or - pressed
Or, after turning off the power, do not connect the phone to the computer for two minutes.
Also check whether the Preloader driver is installed correctly on the computer.
Sometimes changing the cable or USB port helps.
By mistake, we look at the profile topic of the program SP_Flash_Tool.
Screenshots are partially made in SP_Flash_Tool for Linux. On Windows, it may visually be slightly different.
That's all for now, will be corrected or supplemented as necessary.
