I’ve tried to flash reno 3g using windows 7 64bit and encounter lots of problem on driver and flash tool and error such as :
- Failed to open com port
- The secure version of the secure-MAUI
- 3g Brom can not pass bootrom start command. Possibly target power up too early
the solution if very simple, i’ve tried on win7 32 bit
Download MT6577 USB VCOM drivers and V7.5.2.0 KHDMIDE (MIUI 7.5) and SP-Flash-Tool-v5.1528.00
insert usb cable to you phone and pc (without batere), it wil tried to searching driver, point to folder driver that you’ve download
unplug your phone, open flash tool and choose scatter file from firmware
Click download and nsert you phone (without pushing any button on phone)
Done!
