What to do before installing the CX-H501DE-N-170510V115 OTA update

If you have rooted your Tecno Camon CX then you need to unroot by downloading the Tecno Camon CX stock rom and flashing it using SP Flash tool . Its important you take note of your Tecno Camon CX Android phone’s Build Number and find out the Chipset of your Tecno Camon CX because there are 3 known variants at the moment; MT6750, MT6753 and MT6755 . You can find the firmware for all three at the Hovatek Forum .

Also, ensure you’ve reverted to stock recovery if your phone is running on a custom recovery (like TWRP, CWM & Philz) and your battery is charged above 50% to avoid an interruption during the installation of the update.

    1. Its not a problem. It means you have an available update. Take note of your current Build Number then update it

  1. I want to unroot my phone, what are the steps please?
    Also I can’t seem to find the stock ROM for my phone. The model is MT6750T with build number Cx-H501DEFG-N-170829V143. Which model’s stock ROM can I use instead?

    1. To unroot, you’ll need to flash the stock rom for your phone model. Its usually best the build of the rom matches your phone. We can help find a matching build or recommend the next closest build you could flash.
