Just got my LattePanda, really cool device I was in the process of running updates and was informed that windows was not activated so I tried to activate it but got the 0xC004C003 error which is the key has been black-listed. I tried re-flashing with the latest flash file from the guide but I'm still getting the same error after it went through the flashing process.
I have the 4gb 64gb LattePanda and any help with this would be great.

can you verify that you purchsed the LP with a key?
the activation key is stored in the bios chip and should check with microsoft on the initial boot.
these might help

I am having the same issue with my LattePanda.
I have the DFR0419 LattePanda Enhanced.
When I try to activate Windows 10 I get:
"The product key used on this PC didn't work with this edition of Windows. You might need to get in touch with the store or company you bought Windows from, enter a different product key, or go to the Store to buy genuine Windows. Error code: 0xc004C003"
I'm looking for help on this issue.

The 0419 is just for the LP, no windows 10 license. for the 64GB version of LP, you'll need to acquire a license on your own. LattePanda Dev's have stated that including a 64-bit Windows10 license for the 64GB LP would drive the cost up more.
I was about to install my own license of Windows10 on my LP when it wouldn't POST

what do you mean by "POST"?Aft3rburn wrote:I was about to install my own license of Windows10 on my LP when it wouldn't POST.. Having to wait until the 19th to contact the folks at LP
@Phelan58 i can verify this, if purchased without a key from the website you will need to provide you own. is this the case?
perhaps this link might be useful: http://www.tomshardware.com/forum/id-27 ... 4c003.html

got you. FYI you can turn off quiet boot in the bios settings to get POST infoAft3rburn wrote:Hello LattePanda,
POST= Power On Self Test. On most PC's, they display some sort of diagnosis information, or a company logo when the power is switched on.

You can use a product key associated with your Microsoft Live account. Be sure the you are logged in to Windows as your user log in. Try your key. Or you can try a key associated from previous installations of Windows as long as you are logged in with MS account. This could be why it won't work. Microsoft needs to associate with a person's account.
Sighn Out, Log in with MS account. Hope that works.
