Hello, so I've just got my Redmi 3 and wanted to install Xiaomi.eu_Redmi3_V126.96.36.199.LHPCNCK_5.1 on a blocked bootloader (just asked for the unlock today, so I'll have to wait 2 weeks). I have Windows 7 @ 64-bit I installed MiFlash 2015.10.28.0 with all the drivers. My phone boots normally to the ROM I've had with the phone when I received it. Once phone turned on, device manager shows: Android Phone->Xiaomi Composite MDB Interface Mobile devices->Redmi 3 Once phone in the Download mode, device manager shows: Ports(COM & LPT)->Qualcomm HS-USB QDLoader 9008 I start MiFlash, browse the folder Xiaomi.eu_Redmi3_V188.8.131.52.LHPCNCK_5.1 that is on c:\ so it is: C:\Xiaomi.eu_Redmi3_V184.108.40.206.LHPCNCK_5.1 Select Flash all Go into download mode on the phone, connect the phone to PC Refresh in MiFlash, select the COM10 device which is my connected Redmi 3 Click Flash Then it is forever stuck on "Send hello response" I tried for few hours but nothing changed, I have to reboot the phone and I can try again, already did this like 50-100 times so I guess it won't work :/ I went to a friend with Windows 7 @ 64-bit as well, tried to do that and we had an other error: the requested resource is in use.(0x80070aa: open serial port :\\:\COM3) or something like that Is there anything else I can try ? Anyone knows how to help me?
