Looks nice, don’t you think so?

This new upgrade should not be mistaken for the Over The Air upgrade that you can find in the settings of your Infinix Hot Note phone. Infinix Mobile is presently working towards providing an OTA upgrade over the WIFI via the mobile phone, but until then and I shall let you know here at Mymobnet!

Kindly note that Infinix Hot Note users who rooted their devices will have problem with this upgrade, in fact it reportedly crashed rooted phones, ok? So you are warned! Lol am not trying to scare you but take it serious.

Now click here to download the upgrade package. Don’t forget to share with us how you feel about your new upgraded phone. Comments are open for all inquiries.

    Hi Chekwas Ojike
    I installed lollipop 5.1 to infinix x551 hot note since you have to root it, i rooted using zipped folder.But now i need to update but its says you phone is rooted OTA will not be installed.
    When i use super su to unroot, it doesn’t complete unrooting.but when you try to install updates again it tells you unfortunately the system cannot complete the installation.
    Can you assist me on how to unroot it inorder to install the updates please
    nice momments

      Hello Dennis,
      I find this resource from WikiHow useful as an alternative to using Super su. Rooting and unrooting phones can be risky so you are doing anything at your own risk. Let me know if it worked.

        What should i do?

    Must the app be linked to my Mega cloud save acc? The Mega acc isn’t opening. The response is usually wrong password entered even after reopening the acc severally.

      The whole upgrade thing is in the beta. If you are having issues, I suggest you wait for the official OTA 5.1 update to come. Infinix hinted its coming soon

      You have to root your phone first. Maybe you just wait for the official OTA release coming soon.
