How to download official stock firmware for Lenovo Vibe shot Z90

However, before downloading the firmware files for your device, you should always check the following things:



  • The firmware version and compatibility: You should always download the firmware files that match the exact model number and region of your device. You can check the model number of your device by going to Settings > About phone > Model number. You can also check the region code of your device by dialing *#1234# on the dialer app. The region code is usually a three-letter code that indicates the country or carrier of your device. For example, CHN for China, INS for India, etc.



  • The file size and format: You should always download the firmware files that are in ZIP or TAR format and have a reasonable file size. You should avoid downloading any files that are too large or too small, as they may be corrupted or incomplete. You should also avoid downloading any files that are in EXE or APK format, as they may be malicious or harmful.

  • The file integrity and authenticity: You should always download the firmware files from trusted and reliable sources, such as the official Lenovo website or the XDA Developers forum.
