the flash tools say: wrong scatter file format!
What to do?
Extract Mlais_M52_20150721 folder from downloaded zipped folder. Right click & Run as Administrator to open sp flash tool. Navigate to Mlais_M52_20150721 folder and select scatter file. Download Agent & Scatter-Loading should appear similar to this image:

It seems your phone may be 'soft bricked', meaning it can be fixed.
What were the steps you used in:
1) trying to root the phone
2) flashing the rom
I'll try
I would like to make a full backup of current firmware before I go for this.
Could you please inform me how do to that full firmware backup? what are the tools required and guidelines?
thank you in advance.
Sorry for the late reply. To backup your current rom:
(1) first, you'll need custom recovery + root – this a guide for the M52: http://goo.gl/jiCll6
(2) then use custom recovery to back up your current rom – instructions here: http://goo.gl/aI4bP0
(3) after flashing the latest rom with sp flash tool (guide: http://goo.gl/Ua7Vsd), you'll need to reinstall custom recovery & root as per (1). Once this is done you can restore any backups made via custom recovery
Correct link for rooting M52, (1) above, is http://goo.gl/jiCll6
