I also have same problem X008DA indian phone ! after downgrade 7.0 to 6.0 baseband unknwn.

We did mistake ! Prelaoder file shall not be selected while Downgrade.

I think now Flashable Scatter file for 7.0 upgrade can save me !

If anyone have MT6737m scatter file NOUGAT plz provide link !

I used ID_ZC520TL_13.1.1.70_20170421 this file its for X00DA indian model !
your's might be diffrent !
problem in flashing via SP FLASH is ! which ever file you flashed your handset is converted in that Region! so update Nogout dont help!
this model has many diffrences like ID Model, WW- model, TW-model, CN etc ! also diffrence is X008 and X008DA !
