Everything you need from Mango (DVPs normally upgrade to Mango on their own) to 7.8 is there..

#1 - First be sure your phone has gone through the normal procedure to 7720 (Mango)

#2 - Then go here: https://dl.dropbox.com/u/15491148/Update%20-%20DVP.zip

Done.. and done..

OK.. First off remember to move the CABs in order to the folder th BAT file is in, don't move the BAT to the CAB folder.

This will work with any version post Mango.. Just start with the set of CABs you last ended with.

IE, if you have 8107, go to the folder after 8107 and use those CABs..till 7.8..

Other tips..

1) Make sure you have upgrade via Zune to Mango first

2) Make sure Zune is off

3) make sure you install the WP07 support tools before running the BAT file.

4) to ensure a clean install of all filess.. Hard reset the phone. Before installing all the CAB files.

Hope that helps.. Remember when all else fails read the directions.

OK..

> First off remember to move the CABs in order to the folder the BAT file is in
> Don't move the BAT to the CAB folder. (It won't find the program files it needs that way)
> You will know it done with each step, when your phone and the command line says Success! (This will come up each time you go through the Update procedure)
> Don't try to run the BAT file without moving the CABs into the correct folder (results it will not finding the files to update with)
> Don't try to run all the CABs at one time (From all the folders) also can cause problem
> DO copy ALL the files from the INDIVIDUAL folders for each run.. (Some updates required 1 file, some 2, some 3, etc.)

So remember :

Create folder and unzip all the files and folders into the directory (We will call it UPDATE and put it on the desktop for example)

Install WP7 Update Tool (See folder --> update tool - INSTALL FIRST)

Start by moving the files in CABS/7740 folder to the main UPDATE folder you created (the one with the BAT file in it) and run the bat.

In command windows hit <S>

Let phone go through the upgrade process

After successful upgrade, move the 7740 file(s) from main folder, and replace with CABs from the next folder (8107) in the order

Run the BAT again.

>>>>>>>>>>>>>>>..

Also, This will work with any version post Mango.. Just start with the set of CABs you last ended with.

IE, if you have 8107, go to the next folder after 8107 and use those CABs..till 7.8..

2) Make sure Zune is off

3) To ensure a clean install of all the CABs. Hard reset the phone. Before installing all the CAB files. (Not required.. but it doesn't hurt)

Hope that helps.. Remember when all else fails read the directions.

Just followed this on my unlocked AT&T DVP. Went from Mango to 7.8 in about 30 minutes total, with no issues during installation. Still testing the phone out o see if everything works, but so far so good.

Awesome stuff dude, thanks! Very easy to follow instructions that are noob safe.

FWIW, I had success upgrading using this method from 8773, without resetting the device.
