Doogee dg 550 sim and rear camera problem.

[Souldefiler]

My firmware came with 4.4.2 android installed allready everything worked flawlessly and i decided to put a new rom. That was my mistake. I was complete idiot i forgot to do a backup. And i manage to root my phone via V-root. Went to needrom and tried few roms. After i installed first rom from iceman ported cyanogen mod 11 everything worked flawlessly except rear camera. Then i tried rom from baldos81 aosp rom and then rear camera also didnt worked and both sims didnt worked also ( phone cant detect both sims). I,m using windows 8.1 and tried to instal v com drivers but i couldnt. I disabled signcature verification or something, tried to instaled them manually no success. If i could just get sp flash tools working maybe i could save my phone. But i tried every single tutorial i could find on internet with no success. Please guys i found this forum best for things like this. If anyone could help me and save my from this misery. I got my phone 3 days ago and now its useless. Any help is appreciated. Thx in front.
