  1. Please help... Explain in detail where you'll press the 2 volume buttons. I've tried everything it doesn't pass...

    1. after selecting the .pac file, click on start button > hold the device volume - & volume + button together > plug in your usb cord and patiently wait for device to connect.

    2. I've done that but i don't know whether my phone fits your criteria. I use an xtouch e1. it only charges when you insert the usb cord after pressing volumeUp+volumeDown together. Thanks anyway and i'm still open to suggestions

    3. download and install spreadtrum android drivers to your pc, reboot pc after installation, try the steps again using upgradedownload tool or miracle box... if the problem persist then you need to seek a hardware engineer (your device usb port can only charge but it can't connect to pc).....Always feel free to drop your comments.
