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.

How to install the Tecno CX-H501DE-N-170510V115 OTA update

  • If you got an update notification on your notifications bar then simply slide down and tap the OTA Update notification prompt
  • If you are yet to get an OTA update prompt then navigate to Settings > About > System update and search for an update
  • Tap Download and Install
  • Wait for the update to get downloaded (the update is 278.49 MB in size)
  • Once download is complete, tap Restart & Install
  • Wait while the phone boots into recovery mode and installs the update (DO NOT interrupt)
  • The Camon CX should reboot to home screen once the update is completed

How can I roll back or downgrade my Tecno Camon CX after installing this update?

If you find the update buggy, you just don’t like it or you got your phone bricked (stuck in recovery mode) after installing this update then simply download the firmware for your Build Number at our Tecno stock roms collection thread and flash it using SP Flash tool.

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
Boot TWRP
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

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

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.

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…..!!!

Reply
Hovatek

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

Hi
i have a CX Air
everytime i download the update (608 mb)
it finishes downloading then says unzipping error.
please help.

Reply
Enigma

That’s because the update app is being minimized during the update. The goal is to NOT minimize the update app (while its downloading the update) or even let the phone go to sleep. You could set your Settings > Display > Sleep to 30 minutes and touch the screen at intervals so the display doesn’t go off.
You must remain on the update app (don’t check any other app) till its done downloading and installing the update

Reply

The steps to install OTA updates are essentially the same. You can read https://journal.hovatek.com/tecno-camon-cx-air-receives-adoptable-storage-volume-bug-fix-in-latest-ota-update/ . Just ensure your phone isn’t rooted and its running on stock recovery (not custom)

Reply
Jiballs

My phone is already rooted. reason am looking to unroot it or how do i go pass the custom recovery as i have twrp custom recovery on it

Reply
Enigma

This means you’ll need to flash the CX-H501DEFG-N-170720v133 rom to unroot. Have you backed up your present firmware?

Reply
Jiballs

Yes i have backup. so how do i flash this present rom to unroot it

Enigma

Did you backup your rom before rooting or have you found the stock rom for your present build?

Use Magisk at https://forum.hovatek.com/thread-21427.html or port Philz recovery for your build using our tool at https://forum.hovatek.com/thread-21495.html

haaa…i didnt backup the rom before root. i did after root. and my understand is that the stock rom is still intact and only the recovery rom that has been changed to custom recovery. kindly advise

Reply
Enigma

The rom can’t be instact since you’ve already rooted. At least boot.img must have been patched also. Another option is to flash a firmware similar to your Build Number then start installing OTA updates. I would however recommend that you first backup your current firmware in scatter format using Miracle Box @ https://forum.hovatek.com/thread-13347.html

I’ve come across this Build Number. With Tecno and Build numbers, expect to see anything, especially with the CX and CX Air. As for identifying if its original or fake, refer to our guide at https://journal.hovatek.com/how-to-identify-a-fake-tecno-phone/

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?
Help.

Reply
Enigma

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.
