How to Flash Vivo Y91: Understanding the Process

  1. Backup Data: Before commencing the flashing process, ensure that you create a complete backup of your crucial data, including contacts, messages, photos, and any other essential files.
  2. Charging the Device: Ensure a sufficient battery level (at least 60%) to power your device throughout the flashing procedure. An abrupt power loss can interrupt the process and even damage your smartphone.
  3. Download Required Files: You will need a compatible firmware file for your specific Vivo Y91 model. Download it from official sources such as the Vivo website or trusted repositories.
  4. Installing Flash Tool: A suitable flash tool, such as the “QPST Tool” or “Miracle Box,” is necessary for completing the firmware installation. Download and install the tool compatible with your device and operating system.
  5. Entering Flash Mode: Depending on the smartphone model, there are two prevalent methods to enter flash mode on a Vivo Y91:
[1] Fastboot Mode: Connect the powered-off device to your PC using a USB cable. Press and hold volume down while connecting the USB cable.
[2] Recovery Mode: Simultaneously press and hold the power and volume up buttons until the Vivo logo appears.

  1. Flashing the Firmware: Launch the flash tool and establish a connection between the device and your computer. Load the downloaded firmware file into the flash tool and configure the necessary settings. Initiate the flashing process and patiently wait for its completion, which may take several minutes.

  2. Restarting the Device: Once the flashing is finished, disconnect the device from the computer and restart it. Your Vivo Y91 will boot up with the freshly installed firmware or custom ROM.
