My brother has a a6000,he wanted me to make his phone faster and smoother so i installed miui 8 rom on his device ,after a month he got notification update and he update it via updater app. As a result the phone is now hardbricked with no fastboot and no recovery. I try to flash stock rom with qcom dloader 1.02 but it stuck in sahara for a very long time, the i try with qfil and also get sahara error. I try every method to solve sahara error like copy and paste firmware file in c /program file/qualcomm/qpfst/bin but it solve nothing. Please help me if you know other ways to flash stock rom or other ways to solve sahara error
