Device Authentication Error

[rindert]

Hi everyone,

Yesterday I tried to update my HTC Wizard through Windows Update.
After the update was downloaded and installed it had to reboot.
But when the Windows Mobile screen appears, it gives me a "device authentication failure, Please contact the product manufacter. For reference, please provide your device ID.

Then a long serial of numbers.."

I tried to do a hard reset, but no result. :mad:

Is there a solution for this problem?

Regards and TIA

never used windows update on the phone itself before so cant explain why that happened.

What rom are you using is it stock or one of the 6 or 6.1 builds.

might be worth flashing back to a stock rom if you can get into the tricolor boot loader mode as it doesnt sound bricked which would reset everything.

can you get into the phone with activesync to get at the files on the phone?

Windows Update actually WORKED for you? I have never even heard of an update being released via Windows Update on WinMo....are you sure thats what you did?

I have a MDA Vario, originally with WM5, but I've upgraded it to
WM6.
But never updated it to 6.1.
The problem is, I can't get into my phone through ActiveSync.
It freezes when the error appears.

Is there another way to get into the tricolor bootloader without ActiveSync?

@ ashashaur

Yeah, it did.
First the wizard (not the phone) checked for available updates.
There was a update available, so I tried to update it.
First he downloaded it, restart, and installed it.
When it was done, the phone had to restart, and after that, the problem occured.

Man, that is roayally wierd...as soon as I read this today, I hit me own phone upto the Windows Update page, and it promptly returned saying that there are no updates availible...I just dunno what to tell you...have you tried forcing your phone into bootloader mode?

Boatloader: Hold Camera button and press Power button. Wait and a nice tri color boot screen will appear. ;)

glad you got it fixed. what was the fix in the end?

I was able to get into the bootloader, so I could flash it again.
And it works :)
