Error Code Troubleshooting:

Firstly, if you want help in this thread PLEASE tell us what your Computer OS is including if its 32/64 bit. What OS revision your phone is at and What kind of phone along with details of the problem! Thanks!

I found this link to MS for different error codes and a solution grid of sorts that relates to ZUNE etc..:

This is a COMPLETE backup and COMPLETE restore

IF USING ZUNE 4.7!!

. Your phone will be EXACTLY the same after a restore as it was when you did the backup. Any updates, file changes, registry entries, or texts will not persist that were not on the phone at the time of the backup. Sorry for the bold but I have answered this question about a dozen times in PM's or on here.

ZUNE 4.8 seems to only backup whatever Zune does not synch and things like game states! I HIGHLY recommend reverting to 4.7 zune and phone tools if you want a COMPLETE backup. Zune 4.7 cant talk to Mango but it doesnt need to for a backup. A Complete backup made by 4.7 tools WILL restore with 4.8 tools.

Known Issues:

HD2 owners. There seems to be a problem using this method to backup the phone. The current theory is that the HD2 does not use the same boot loader as other WP7 devices and is not recognized correctly in that mode so it doesnt work. I would be interested in knowing how your updates are applied as the log I got from one user indicates the phone talked to the update program once it rebooted?!

Additional tips and observances:

*You CAN'T change the memory size and perform a restore, I already know this doesnt work so forget about adding memory and just restoring :(

*To my knowledge you can't backup from one device and restore to another as the backup files are signed/ID'd to the device that made the backup.

How to restore a backup via ZUNE if you don't want to use the restore feature:

Make sure your phone is hooked up to the computer first then from within the ZUNE software you should see a menu near the top right-hand side labeled "Settings". Click on that. On the settings screen look near the top left and you should see "Software" "Device" and "Account". Instead of device it may say "Phone".

Click on Device or Phone, whichever you see. The left edge has several options. Near the middle you should see "Update". Click that. You should see a progress bar for a few seconds and then most likely it will tell you that the phone is up to date. At the BOTTOM of all the text it spits out should be a button labeled "Restore" with the date of the backup.

BACKUP CREATION LOCATION:

Copy & paste the following in to the run dialog box:

Vista/Win7: %LOCALAPPDATA%\Microsoft\Windows Phone Update

Win XP: %USERPROFILE%\Local Settings\Application Data\Microsoft\Windows Phone Update

If you are running the backups with elevated privileges then you need to open a command prompt with those same privileges and paste in the above paths to find them as they may likely be in a different user account.

You will have to manuall drill down from their because the sub folder structure is named from the Phones ID.

Manual Command Line Method to Perform Backup:

All the same prerequisites apply. Zune and the windows phone support tools need to be installed.

It is easiest to have unzipped the PKS file in to folder the support tools are in. You can do this by opening the run dialog and typing: %PROGRAMFILES%\zune and hit enter or click ok. This will open explorer to that folder and you can move/copy the UNZIPPED PKS file there.

Open a command window with admin privileges. To do this in windows Vista/Win 7 with UAC enabled click on the "Start" Windows logo usually found in the bottom left corner.

In the search programs and files dialog type CMD and wait for the search to produce CMD.EXE at or near the top of the list. RIGHT click on cmd.exe and choose "Run as administrator". (hopefully you don't have to input admin credentials to do this)

At the command prompt type: cd %PROGRAMFILES%\zune (and hit enter). Your prompt should change to include the program files path and ZUNE for example "c:\progam files\zune"

Now assuming the support tools are installed correctly you can test by typing: updatewp (and hit enter) this should spam the screen with the command line options for updatewp and lets us know the rest will work.

The command to type is: updatewp.exe /iu A0CE706D-12B7-45AC-A5FC-AD04DFCA6E86.100.pks /enablebackup (and hit enter) You should be able to copy the command line as it is and right click on the DOS window at this point and choose "Paste" to save the trouble of typing that awefull string.

This is all the program I wrote does to start a backup other than kill the update process at the end since it can't happen.

I hope this works for you if the code does not!
