How to install the OTA update
You can proceed in two ways: by applying the update from the recovery of the smartphone or by acting via ADB from a PC.
For the recovery procedure, just place the ZIP file of the OTA update in the internal memory of the device, restart in recovery (turning off the device and keeping the volume down while pressing the power button) then from the recovery select the item Apply update from SD Card(to select use the volume keys, to confirm the power button).
Select the ZIP file of the update and wait; at the end select the item Reboot system now.
If, on the other hand, you intend to update your device via ADB from a PC, you must first download basic components (ADB and Fastboot) to your computer, which can be quickly downloaded from the following guide.
Once the PC is prepared, enable the USB debugging on your smartphone from the menu Developer options. To make this menu appear, you need to go up Settings> Phone info and click repeatedly on Version numberuntil confirmation for the new menu appears.
Now connect the smartphone to the PC via USB cable and open a command prompt inside the folder where you kept the OTA file (I recommend you do this before typing any command) by holding down the SHIFT key while clicking the key right mouse button, then selecting the item Open prompt here or open Powershell here.
The command to type the following:
adb reboot recovery
The smartphone will restart itself in recovery; scroll with the volume keys to select the itemApply update from ADB.
Now from the prompt that you left open on the PC type the following command:
adb sideload file_ota.zip
Instead of file_ota.zip obviously type the name of the file for the update. Confirm and wait for the procedure to finish, then unplug the USB cable and use your voiceReboot system nowfrom recovery to restart the system.
How to install the Factory Image (full format)
If you intend to install the Factory Image the slightly more complex procedure, but following all the recommended steps you should have no problems.
Enable the USB debugging on your smartphone from the menu Developer options. To make this menu appear, you need to go up Settings> Phone info and click repeatedly on Version numberuntil confirmation for the new menu appears.
If you have not already done so, install the fundamental components (ADB and Fastboot), which can be quickly downloaded from the following guide.
Now connect the smartphone via USB cable to the PC and, from the folder where you have unzipped the contents of the compressed archive of the Factory Image (if you have not done so, create a folder on the desktop) hold down the SHIFT key while right-clicking mouse, then select the item Open prompt here or open Powershell here.
From the prompt, type the following command:
adb reboot bootloader
The device will restart in bootloader mode. If you have not already done so, unlock the bootloader by typing the command:
fastboot flashing unlock
Now go to the folder where you unzipped the ZIP file containing the Factory Image and run the fileFlash-all. The device will be completely flashed.
