Trying to update your Infinix Hot S (X521) to Nougat? Your Build Number matters….as always!

Its the season of test Android Nougat (7) OTA updates as promised by Infinix. There’s been the Infinix Zero 4 (X555), Infinix Hot 4 (X557), Note 3 (X601-H536A1) and Note 3 Pro (X601-H537A1) which have received their test Nougat builds and now the Hot S (X521) but only for the A1C1 & E1G1 Build Numbers .

The Infinix Hot S (X521) has several builds as listed at our Infinix stock ROMs / firmware collections thread ranging from the A1, C1, E1, G1 to the I1. If you’re looking to install this Nougat update then ensure your Build Number matches else you could end up with a bricked phone.

  1. 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.

  2. 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.

  3. 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

  4. 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.

  5. 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.

  6. 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
