How to get a dump of Windows Phone 7 when Updating
This is my first post here at xda. I was using the zune nodo update on my LG optimus 7 and while it was doing the backup of the device I noticed that it was saving it to the HDD. So I did some browsing and copyed the contents of the backup to my desktop.
I found the backup here(C:\Documents and Settings\<username>\Local Settings\Application Data\Microsoft\Windows Phone Update) *win XP.
After opening the data.0 files I found that they are all 4mb in size exact. And there is a 128kb file at the front. The 128kb looks like the bootloader and the 4mb look like direct nand dumps from the device.
The 128kb holds info for the IMGFS, and has AES, and something about external storage.
At the end of the backup there is an xml file which tells zune how to recreate the dump for the phone.
I hope this helps someone who is doing some dev work on the windows phone 7 platform.
