Solution to Error 801812C1 during Step 6 of February Update (7004:7008)

---

Great News! I have stumbled upon a solution for the 801812C1 error!

I have reasons to believe that this works for LG E900 Optimus 7 phones. If you want to try this on your Samsung Omnia 7, please read my note at the end of the post.

Here's what I did (LG E900 Optimus 7 / Windows 7 64bit):

During Step 6 (Rebooting your phone), your Windows OS detects your phone as a new device and starts searching for driver updates online. This can be seen when you click on the little indicator with a spinning green circle in the bottom-right corner of your desktop called the notification area (you might need to click on Show Hidden Icons if it's hidden).

You have to *immediately* click on "Skip Obtaining Device Software Online" or Zune will time-out and show error 801812C1.

Once you've skipped obtaining the drivers online, in about 20 seconds or so, your device will be recognized and you will be promptly taken to the Step 7 of the update.

Note for Samsung Omnia 7 users:

Even if you've gotten past the Step 6 801812C1 error, many users are getting stuck at Step 7 at 100% of 'Backing up your phone' resulting in a few users getting their phones bricked -- you might want to wait till that issue is resolved before trying this fix.

Hope this helps.

I just hope this solution doesn't jump them to step seven with that step resulting in a bricking regardless lol

Tejazz,

Thank you!

I don't know for sure but I think we already have the drivers installed with Zune software -- it just checks for newer drivers online which takes too long and makes the updater throw an error code.

Update WP7 driver on PC

---

1. Shut down the phone
2. Restart the phone and hold on the camera button
3. A black screen appears showing a device connected to a PC
4. Connect the phone to PC on USB
5. Open Device Manager on PC and check the entry for Portable Device: Schubert (HD7) or other (but not 'Zune' !)
6. Shut down and restart the phone
7. Connect the phone to PC and run the WP7 upgrade from Zune application

The error '801812C' no longer occurs at step 6.

FIXED error code 801821C1

FIXED!!!! I was having same problem with my Dell Venue Pro Cell Phone with Windows 7. After trying all the steps I found on every forum. I restarted both my phone and computer multiple times., nothing seemed to work.....I always just use the closest USB cord I can find that fits my phone. I decided to try the USB cord that came from Dell with my phone. This worked the first time. There must be certain drivers that are only found the the company specific USB cord. So I recommend trying your HTC original OEM USB cord. Hope this helps
