for the .cabs you need to image update the phone (no need to reflash or hardreset)
Before you continue, you may want to make a backup of your device for in case something goes wrong. You can do this with the update tools, but I use a separate tool to have more control over the backup-process. This is what I do to make a backup:
Setup the Backup tool to reference Zune.exe and the UpdateWP.exe in the extracted Tools-folder.
Create your backup.
The backup app will allow you to archive any previous backup.
Your phone will restart and go in Download-mode.
When the backup is finished, the app will tell you to disconnect.
Even though your phone says you still can't disconnect, you can safely disconnect the phone and it will restart.
INSTALL WP7 UPDATE TOOLS
First make sure you have Zune 4.8 final (build 4.8.2345.0)
Download the WP7_update_tool.rar and install the UpdateWP package for your platform (x86 or x64). This is version 4.8.2134.0.
Download the WP7 Update Cab Sender.zip from xboxmod and extract it. This also contains a patched version of UpdateWP.exe which will work with Zune 4.8 final.
INSTALL THE UPDATE PACKAGES
Copy all the CAB files you downloaded to the folder where you extracted xboxmod's WP7 Update Cab Sender. The CAB's should be in the same folder as the BAT-file.
Run the batch-file and press 'S'.
Your device will reboot and start in download-mode.
You'll see progress on the screen of your desktop, but it may take more than 10 minutes before your WP7 device is starting to show a progress-bar, even for small updates. That's normal, because the device is scanning for installed packages and performing merges.
When the update is ready, your device will be rebooted again and it will boot Windows Phone with new version and or custom packages.
Well done!!! Thanks for your work (really hard) and for nice promo videos!!! You work was really hard because you're the only sammy-guy in the team
