Recovery Update Method




This method is more complicated and time-consuming than the local update method. However, it can be used if your device is rooted or has a custom recovery installed. Here are the steps:


  • Rename the firmware file from your PC to update.zip.



  • Create a folder named dload in the root directory of your device's internal storage or SD card.



  • Copy the update.zip file to the dload folder.



  • Disconnect your device from your PC and turn it off.



  • Press and hold the Power, Volume Up, and Volume Down buttons together until you see the Vivo logo on the screen.



  • You will enter the recovery mode. Use the volume buttons to navigate and the power button to select.



  • Select wipe data/factory reset. This will erase all your data, so make sure you have a backup before proceeding.



  • Select wipe cache partition.



  • Select wipe dalvik cache.



  • Select apply update from sdcard.



  • Select the update.zip file that you copied earlier.



  • Select Yes to confirm and start the installation process.



  • Wait for the installation to complete. It may take several minutes.



  • Select Reboot system now.



  • Your device will restart and apply the update. Do not turn off or disconnect your device during this process.
