  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.

        1. There are no 100% guarantees. I would advise you not flash the update if you’re not willing to take the risk

  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?

    1. 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.

  4. I download the file and updates it every thing was good but the charging animation when phone is off is not in Other any fixe for that

  5. Please what’s the latest update link for J5088A1 build number? Which should be downloaded? Because I downloaded one of A1C1 which required frequent reinstall on WhatsApp. So please, kindly notify me asap on the latest and bug free update. Thanks.

  6. My hot s version is j5088a1- m170323v153, I want to update my phone but it says cache not enough pls I should insert SD card to download, will SD card for 4gig be enough to download or update my phone.

  7. Really I don’t know what ota or tcard means, all I just got when I wanted to update my phone system was, cache not enough insert external SD card, what ota t card means I don’t really know

  8. Hello i can’t download the TFCard file on A1C1, it’s out on google term services. Could you reupload it? thanks before

  9. How do I update after downloading the file? i didnt update when beta 1 and 2 was released. I downloaded the file through my pc and copied it to my mem card. i update from local but then it says “the current package is not available…” please heeeelp!

    1. 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

But when i make its hotspot and someone use it by wifi on other phone , internet speed is fine on other phone. Kindly suggest how to fix that issue

    1. 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
