Quick reply... Microsoft Windows users who wish to update their N900 can use the Nokia Software Updater (aka NSU)... The Nokia Software Updater can now be used when updating from a previous firmware to a new one or re-flashing. I am absolutely sure that it is possible to update from one version of firmware to another by using Nokia Software Updater (I have done it once, long ago). However, I cannot guarantee that it would be able to replace a non-India variant of firmware with a variant of firmware for India. I suppose it will not hurt to try using NSU, though; if, after updating the device through NSU, it still has any problems, you may have to use the flasher and command-line, again. First, make sure your Nokia N900 is completely, fully charged. Second, connect the N900 to the PC, using a USB data cable, in PC Suite Mode, and open the Nokia Software Updater application. Then, use the NSU. I am not sure what its interface looks like, because I haven't used it for a long time, and right now it is updating itself (very slowly, at excruciating pace). __________________ If you still have problems connecting Nokia N900 to PC in PC Suite mode, describe them? Best wishes. __________________ Per aspera ad astra...
