please confirm. I think Tecno CX is a spreadtrum device. You can not use MTK methods. It will be best for you to download the firmware of your device before you even try what you haven't done before.

As @X3non said, a box is your best bet. If you must go with SP Flash tool readback then you don't have the luxury of bumping into errors else your phone could go dead.
Now, you need to upload full screenshots of sp flash tool. Follow the guide @ https://www.hovatek.com/blog/take-screen...nter-free/
I want to know which
1. partition you're trying to dump
2. the values for start and length you're using

Also, a full screenshot of SP flash tool once the error pops up

Note!
We have a reply schedule for Free Support. Please upgrade to Private Support if you can't wait.

Here's how to...
Assuming you're not rooted
fastboot boot twrp.img don't flash
Keep system RO
Backup system,boot and recovery to SD card
The second method is dumping partitions using terminal either in recovery or normal mode,in normal mode you'll have to install systemless SuperSU and at this point the only partition that will be modified is boot of which SuperSU makes a backup to /data and you can rename that file to .IMG as it is or rename recovery.emmc.win001 in TWRP backups to recovery.img and reflash back either by fastboot,spft or TWRP.
Commands
su
ls -l /dev/block/platform/mtk-msdc.0/
11230000.msdc0/by-name
This will list all the partitions names , permissions and owner,let's now dump one by one ,for example for the boot partition,command
dd if=/dev/block/mmcblk0p20 of=/sdcard1/boot.img
for system
dd if=/dev/block/mmcblk0p26 of=/sdcard1/system.img
Repeat this for all the partitions and at the end you'll have a "stock ROM” that you can even flash with SPFT if you have a scatter file.

The first method I tried when I was in version 107, but when update came it failed boot I had to flash stock rom and start updating from v91.
