  4. Amol, its ok. Asking questions will only help you learn better. For connecting the phone to PC, you can use the USB data cable that is acompanied with your mobile phone. Connect the phone and the computer with the help of this USB data cable and then enable USB debugging. USB debugging can be done this way:
    in your phone go to:
    settings>development>application>USB debugging enable(check that box).
    ok, i hope this part is clear now. After this the hashtab part comes. Check this link and read it thoroughly. It will help you.

    • Yupp, its clear now, the topic of Hash tab…thanks for that Samvedana… But when m connecting to PC in USB debugging mode, it is asking for the Micromax A75 Drivers… It searches but there are no drivers… where shud i find that…?? I m having Win XP in my PC….

    I tried rooting the Mmx A75 as directed here and on xda forums. However, just after the root, my screen went white and though I can hear the boot-animation, all I see is just a white screen.

    I have flashed 3/4 times after that and yet no effect. Does anybody know what could be wrong here? Any help will be highly appreciated.
