I completely agree with Icedhat on this one. Unfortunately I have tried every possible user created workaround in these forums and nothing has worked, including using Unzoone.
I have a sticky situation as well.
Basically, as with everyone else, when I upgraded to software 4.0, my Zune30 stopped working. Would not be picked up buy the computer all of a sudden, yadee yada...and would go through the endless loop of installing and restarted. Followed steps to uninstall driver from Device Manager, and then plug it back in. Picked it up, installed driver, now Software 4.0 picked up the Zune..however it would start syncing and just stall at like 14% or something, and nothing never went over.
So, I uninstalled firmware and media content from Zune30, plugged it into the PC. Software 4.0 picked it up, said it needed to install the firmware...said it was going through, yet at the end I was left with this pleasant error code during the firmware update: C1010007 (player disconnected or something like that ). Checked Zune30, and it said the latest firmware was installed 3.20, yet now it's back to square one where Zune software and my computer attempt to reinstall drivers, but just keeps looping after restart.
So, I said let me try a ZuneHD (figuring it was time for a new one anyhow). Plugged it in, get the SAME INSTALLING DRIVERS, PLEASE RESTART LOOP. Go figure...even the HD messes up.
Called tech support, no answers, but good tries, and they will get "back" to me, as this apparently is a known issue. Just an FYI, after sending MS support my diagnostics, all is well on my side and I am using Vista 64bit Home Premium.
Anyone else with the same issues with Zune30 and ZuneHD?
P.S. Microsoft at least acknowledge there is an issue and a patch is imminent, cmon!!
