I have lenovo a606 mt6582. forum member asked me to upgrade the firmware by flashing (download) only the system.img and i did. but the outcome wasnt nice.. it ended soft bricking my phone.. i tried restoring backup through mtk droid but the TWRP doesnt mount /data, this and that, almost everything. So i tried with TWRP backup, well... it wasnt successful though... help please... I need my phone tomorrow and here is midnight now..
