What do you think ?
Is there hope?
There's always hope - stay strong!
Are you trying to reinstall the current v2.0.4 of HTCSync? The driver(s) in that may be newer than the v2.0.2 (?) shipped with the handset.
Now.... with the Hero connected via USB is an "Android USB Device" still displayed in Device Manager? If so expand that to show the actual device itself, right-click and choose "uninstall". If not move on to the next step.
Disconnect the Hero, reboot, and if you haven't already done so uninstall HTCSync from Add/Remove Programs. Reboot again, and check that there's no
/Program Files/HTC folder remaining. If you find one, delete with extreme predjudice! Be warned, if like me you habitually install programs to other than the default system (C: ) drive, there will still be a
/Program Files/HTC tree there anyway. Wtf HTC???? Anyway..... now look in
/windows/temp (or wherever you've set the TMP/TEMP variables) and delete (a) any
_HTC*.* files, and (b) any folder containing
HTC*.
msi. I'd also suggest sorting by date modified, select all files modified more than 48hrs ago and deleting them too. Then examine what's left and delete anything that you can. Windows is notoriously bad at tidying up after itself and often leaves remnants of old installations lying around. If the OS is using a file it won't let you delete it, but anything else is, in my experience, fair game for the shredder. Finally, have a look in
/windows/system32/ for WdfCoInstaller01007.dll
and in /windows/system32/drivers/ for ANDROIDUSB.sys. If you find either delete them 'cos the driver uninstall should have nuked them anyway.
Still sane? Then reboot for a final time, remember to temporarily disable antivirus software, and try installing the latest HTCSync once more. Hopefully you'll have eliminated all traces of the old driver and the new one will go in smoothly. Cross your fingers, connect the Hero and it
should sync when asked.
p.s. Double-check "USB Debugging" - mine mysteriously turned itself off sometime today and nerfed the sync!
p.p.s. Somebody proof-read this and make sure I haven't missed anything. It's late and I can't drink any more espresso if I want to sleep some time this week!
