But when i connect it by USB i can see that its MTK USB Port, or MTK DA port or something like this (that's after installing drivers, before I installed it i was getting Unknown Device on the list - it shold be MT65xx Preloader) So i tried to flash a stock rom (SP flash tool), but i can't do it too - I'm getting error connected with DRAM, or the red bar is loading like 100% and then nothing..I can wait and wait and nothing more...
I didn't broke my phone like it was never on the floor or something like that and I didn't change Preloader by SP Flash Tools
It's very important to me to fix it fast because I'm working on dual sim and I need smartphone... I don't want to send it back to China - it would take at least 2 months to complete repair, so I'm determinated to do it on my own, but I need your help...
if you didnt mess up with anything, its hw issue i would say
