  1. Bro I have Infinix hot s the build number is j5088e1-m-170323v23 I just wanted to ask is my phone compatible for this update.

  2. Hello
    Been following up on this conversation. I have the same build and I am downloading now… To follow up on the instructions. I have a question though, what happens when a phone gets bricked?

    • Well, if you go through the guide carefully, you’ll notice that it emphasizes backing up your current firmware so you can easily revert (unbrick) if the Nougat update bricks your phone.

  3. I have updated mine, I used the scatter file and updated using infinix firmware updater. I previously saved my data as this method formats the phone.
    PS: I installed custom TWRP recovery first. Also, it doesn’t matter your current version as this method installs a fresh version of the OS.

    • You best flash back your stock recovery if you plan using Tcard. If you’re however updating using SP flash tool then yes, you can untick recovery and flash the rest but there’s a very good chance that the TWRP recovery won’t be compatible with your phone after the update

    • An update doesn’t necessarily mean all issues on your device will be fixed. Your trouble using mobile data might be due to a blacklist / data management app which you have installed. Look through your list of all installed apps
