Quote: BACKUP



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: Download hx4700 Killer's WP7 Backup version 1.6 from this thread. Note that I use version 1.6, not 1.8. Download this archive. It is from xboxmod's WP7 Update Cab Sender thread. Use Zune 4.8 final (4.8.2345.0). Setup-UpdateWP 4.8 beta 3 from the archive. Extract the "Tools" folder from the archive. 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.

People with generic DVPs are going all the way to 8107 through Zune. But those of us with "branded" devices (no difference, really, except a couple of digits in the serial number) - even if SIM unlocked, even if running on another carrier altogether - are stuck on 7720 unless/until T-MO and/or AT&T decide otherwise.Various threads have pointed to the Cab Sender method to force the 7740 and then the 8107 updates. The xda thread instructions are complex enough to have spawned several how-to rewrites, but this thread aims to provide draft instructions for TMO-US and AT&T branded Venue Pro phones.Download these cabs:I'm pretty sure we only need these three, because 0409 (U.S. English) is the only language I'm able to select on my DVP right now. If anyone is aware of more language packages that *need* to be installed (i.e. if not, there will be old language packs on the device and it will be "Walshed") please post.I'm also pretty sure there are no OEM updates from Dell past 7720.Next, we need the tools listed in the first post of this thread: http://forum.xda-developers.com/show....php?t=1306415 These are the instructions from the general thread:This appears to just require the first update cab listed above - there's no language update. Copy that cab into the main working folder (the one you extracted from WP7 Update Cab Sender.zip), run the batch file and type "S").The actual cab should load in like 2 seconds, and the round-trip time is just over a minute. Your DVP should boot up again - go to Settings, About, More Info and confirm that you're now at OS version 7.10.7740.16 (the Firmware revision number will still contain 7720).Now take the first cab out of the working folder, and put the other two in - the ones that reference 8107. This is the OS and the 0409 language update. Run the batch and hit S again.These cabs will take a little while longer to install - maybe two minutes total. Device reboots and spends a little bit of time at the "Windows Phone" splash screen. Check OS version as before, and now it should read 7.10.8107.79I hope this walk-through helps calm the nerves.Forum veterans, please post any additions/corrections you'd like to see. Also, an open question: are there any particular Yuki/Xboxmod customization cabs that we should be checking out on the DVP? I know their CABs are aimed at interop unlocked HTC devices, but some are simple reg edits that might be applicable to us, no?
