This update seems quite buggy so you best take these precautions before updating:

Take note of your phone’s present Build Number (Settings > About > Build Number), you might need it to rollback to a stable firmware
Backup / dump your phone’s current firmware in scatter format using Miracle Box so you have a safety net in case you find the update too buggy or brick your phone in the process. You could also check our Infinix Note 4 X572 stock roms collection and download one for your phone’s Build Number if you have trouble backing up
