I'm selling my pulse and as the custom rom I was on wasn't 100% stable (problem with downloading apps)I want to sell it with the original rom. Whats the quickest way to do this?

Just apply the December update from the T-mobile website, by following their instructions

Can I flash the December update from RA recovery system to reset the Pulse back to manufacturing settings. When I follow t-mobile instructions it doesn't recognise the update.??

Edit: I should read the instructions forgot to extract the zip file, just thought put it in my SD route

Then follow the steps below to update your phone:

Download the update file

Okay so still no go with flashing back the original rom.

I get error message:

"The upgrade is not detected. Confirm the upgrage package, and then perform the upgrade"

Unzip the file U8220V100R001GBRC85B118 SP01 with_Userdata.zip to a location of your choice on your computer

Copy the files you just unzipped (the “dload” folder and all its contents) to the root directory of your MICRO SD card

Insert your MICRO SD card into the handset

On your Pulse, go to the Main menu, then select Settings

Within Settings select SD card & phone storage

Scroll down, under the Internal phone storage section select Upgrade

The upgrade process will give you several warnings which you need to confirm to continue

Then press the Upgrade option to begin the update

As the update progresses you will see several screens along with a progress bar

Once complete you will see a confirmation screen, and your Pulse will automatically restart

Once restarted your Pulse will be up to date with the latest software

got it to work. Looks like it didn't like the partitioned SD card. Popped in another formatted SD card and it worked!!!
