Hovatek team, If possible could you provide system.img from v198 of "Tecno camon i2" from an unrooted phone . Mine is rooted so backing up rom will not solve issue for me.

that's not available
if you rooted your device using magisk and you haven't modified system partition then it'll still remain as stock
if not then you can flash lower firmware build, update to the version you wish to then make a backup if the system.img

I was wondering that if I make a backup of my stock rom using TWRP, is it useful or not as I want to provide backed up file to you guys so you can preserve it for future use for other users or I have to backed up using dump method to share it with you.

not sure if your device will request for a -verified or -sign firmware if you try flashing using a dumped firmware
but if it doesn't i.e you can flash your dump firmware using sp flash tool without problems, then dump firmware will be far better than twrp backup
