[HD7 General] xdrc45:
I've noticed there's not alot of information out there available for this topic.

Here are a couple ways to restore your Apps and some data after flashing, hard resetting or changing/upgrading the SD card on your HD7.

1. To restore all of your OEM applications: Download and install "Reinstaller" from the marketplace or from the link below. Open and run the application, you will have to log into your windows live account and then it will bring up a list of all the apps that you have installed onto your device, free and purchased, and yes you can reinstall purchased apps with out having to re buy them. It will give you an option to choose the apps that you would like to reinstall. Select the apps that you want and click the download/reinstall button. It will start the download process and bring up each app individually, click on install app and it will take you to the marketplace, click install and then it will take you to the phones app screen and show the app being installed with a progress bar. To speed up the process arrow back twice - through the market and back to the Reinstaller app and it will bring up the next queued app to be installed, just repeat the steps.

2. Pictures: First you must back them up. Download and install SkyDrive from the marketplace or from the link below. Open the app and login using your windows live ID. Click the add button and it will take you to your pics menu, select the pic you want and it will upload it to SkyDrive. To move mass amounts of pics its easiest to connect your device to your P/C and sync with Zune, save all pics to a separate new/folder in documents. Open SkyDrive in another tab and choose the upload option, it will open a secondary window and browse for your folder. Open the folder containing your pics and right click, scroll and highlight all of the pictures, right click again, and select the contents ( you can't move the whole file folder to SkyDrive ) it will then upload all the pics. To restore them to your device, open the SkyDrive app and log in... It will automatically sync the pics and you can find them in the picture menu under albums.

3. SMS: Download and install SMS backup, (by shinichi_wtn) from the link below or from Bazzar marketplace. You can save all your SMS to an isolated storage such as your P/C or upload them to SkyDrive. Very simple and easy to use. Choose the method of export you want. Export your SMS and then choose the backup option.

For SkyDrive it's saved in a folder named "SMS folder", it's a private folder for "Just Me". You can also find the backed up SMS in your Microsoft Office app in OneNote. Here's the link from the author and with more details/instructions:

4. Contacts: If your device isn't on Tango 8779 build and doesn't have the option to export contacts to SIM. There is an app WlanSIM ( by pdaimarejam ) on Bazaar marketplace or in the link below. This will allow export and import of contacts to SIM and save them there. After flashing or doing a hard reset on your device, on initial setup it will give you the option to restore/import your contacts from SIM back to your device. Make sure your contacts are saved to SIM before doing any operation that will remove them. You can do so by editing the contact and it will then give you the option to save that contact to Sim. As of right now you have to manually edit the registry value and insert this one and then restart your device. HKEY_LOCAL_MACHINE\Software\Microsoft\Contacts\Sim]

"EnableSIMAddressBookAndExport

This app also allows you to set a static IP for WIFI
