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.

Actually you don’t need to unroot to install this OTA
Make sure you reflash system.img or just skip if you haven’t deleted system files. You can flash this in TWRP and choose flash image,and also the stock boot both of build CX-H501D1-N-170405V107.And then after the OTA has finished downloading navigate to /data/user/0/com.mediatek.systemupdate/ copy the update.zip to internal or external SD.
Follow this order
Copy the update.zip
Having system.img and boot.img
Click install,install image choose system.img and restore as system image partition,and boot.img as boot partition.
Install the update.zip
After finishing install SuperSU to patch the boot image
And reboot


It’s hard to follow, please make a video.

1. At what point did your phone go off?
2. Was your phone rooted before installing the update?

Please help my camon cx closes any app i minimize i have checked my developer settings and i didnt on anything that off minimized apps.
Not even my hi manager please help me


what’s the current Build Number?




That’s a RAM management bug. You need to root then install RAM Manager Pro


Good evening, Pls my tecno canon cx is saying storage full each time I want 2snap and I have just 50pictures on it, but I noticed on storage, system is showing 12gb, what should I do please.


You need to clear phone storage. Go to your Settings > Storage and check how much free storage you have under both Phone and SD card storage


Update failed. Perhaps because of the TWRP recovery. When booting i always get an error message saying my phone cannot be trusted. How do I fix this ? please help me!


The guide says to unroot and revert to stock recovery.


Will I lose my data? I really don’t wanna lose my data over that update.


OTA updates don’t affect data


You shouldn’t lose your data over an OTA update


Plizz i need assistance.. my camon cx screen is going crazy after update, apps keep opening and closing by themselves, swipes left and right by itself and sometimes stops as if nothing is wrong… now there is an invisible line at the middle of the screen, all apps which are located within that line are not functioning, if you open keyboard, all characters which are located within that line are not functioning….! is this a touch screen problem or digitizer? and if so, why sometimes this problem doesnt show up as if everything is fine…. i didnt crash it in any way…..!!!


You should have the screen / digitizer replaced. That could explain the random screen touches and line
