After updating Android 10 experiencing some problems. So I wanted to go back Android 9. But I do not know the procedure. If anyone knows what will help?


  • JUST follow the simple instruction CAREFULLY specially STEP 2:

    Step 1) Download Android 9 Firmware file from asus website.

    Step 2) Rename the downloaded file to the name highlighted in bold UL-ASUS_I001_1-ASUS-17.0210.2001.65-1.1.97-user.zip

    Step 3) just put this file in the internal memory as u did while upgrading to android 10. Restart and mobile will detect this file and it will get installed.

    Step4) Thats It !!!!
