Hi all, First off I need to say that I have tried most of the tricks I have found to make this work. Downloaded and tried the 3 latest versions of HTC Sync, installed the drivers manually (first off using Vista x64 drivers, then using win7 drivers from 2.0.18 sync update), downloaded and installed windows mobile device centre to get some of the mobile services (this was recommended on another guide). Rebooted and reinstalled multiple times, it feels like I've tried everything. Ok, so I have the latest ROM for T-Mobile, latest Sync, my Windows 7 Home Premium is fully updated (or was before I came home a few days ago), installed the drivers. I CAN sync my phone with my computer, I can also take files from the phone via usb. My problem lies in the fact that as soon as I turn on Mobile Network Sharing, it tries to install the drivers and then says it can't. So I install them manually, but during the install of them it tells me 'This device cannot start. (Code 10)'. This is in regards to the NDIS drivers. I know I have them all up to date etc, but this is really infuriating. In the devices and printers screen the android phone is coming up as 'HTC NDIS Device #3' (3 because I have tried it so many times) with the little ! by it and it's fix is to try intsalling again which of course gives the same problem. As soon as I turn off the MNS it goes back to sync + usb connection fine and I can again search it for files etc. No matter what I have done, I cannot seem to get the device to 'start' which is what it wants. I was able to get this to work on my old laptop on winxp, but now I have upraded that to win7 as well. I'd really appreciate any help on what seems to be an old topic here, as when I came home to my parents for easter (they refuse to get the internet ) I thought this would be easy like it was for winxp and I need the internet to revise for exams. Jake P.s I am currently using PDANet, but it is really slow compared to how it was on my laptop, and when the trial period runs out I can't log into my uni files to download lecture notes.
