Hi, guys and I am sorry for my English :D Today I tried install on my Lenovo Vibe X3 stock ROM using QIFL. There is one problem, QIFL shows download fail. It looks like this:

please halp

try it again i was also got stuck in this process but after reading some post i tried it again and i got success in it, just as u plug the usb press power button(within a second) you have to be very quick, then at desktop it display the port, leave the phone on a stable surface so the usb connection be stable, as soon as u see the port device hit download button, if it shows download failed, then again hit the download button, it will surely get started, but u have to do this process until the lenovo logo appears, if you reached lenovo logo then you have to power off the device and try it again

I had this problem too... Your driver is not support to flash... Please check before download button...Check your port is visible or not... ! Try to install in windows 7 windows 10..


My device port is not visible in windows 8.1 so I tried in windows 10 ... It detect my port ... And I did it successfully
