[Nokia Lumia 800] biktor_gj:
The good thing about linux is that it detects the filesystems inside a partition even if its IDs are wrong, If I plug it on Windows (windows 8 consumer preview but it will work perfectly well on any other OS with usb disk support) it detects it as a USB mass storage device. The problem with Windows is it doesn't correctly detect the Fat32 partition (the partition containing adsp, amss and emmcboot) and asks if you want to format it. If it asks, SAY NO.

With the phone OFF, press and hold Volume UP+Volume DOWN+POWER until you notice a short vibration. Then plug it to the USB port and Windows should install the device like any other pendrive or usb hard disk.

This are the IDs (vendor:device): ID 05c6:9006 Qualcomm, Inc

As you can see it doesn't detect it as a Nokia phone, but a Qualcomm device. That's why I think some engineer at Nokia left some Qualcomm diagnostics application available on the phone. I don't know any other phone with this enabled, but there's something similar on a Huawei X5, which also uses a Qualcomm CPU. But to make my point clear, THIS SHOULDN'T BE ENABLED ON A PRODUCTION PHONE.

Also, just in case you need some more information about my phone:

Attached to this post you'll find:

EMMCBOOT.MBN: WinCE loader extracted from the Fat32 Partition

SDB1.ZIP: Contains a full dump of the first partition on the nand, containing the initial bootloader. I think this is just default Qualcomm bootloader

SDB2.ZIP: I think it has the second stage loader, including some kind of firmware update system.

SDB6.ZIP: Contains a full dump of one of the three 3Mb size partitions which I don't know what they are. Maybe you're luckier than me with them. I'd post my entire flash, but it has phone's IMEI, and all the file system on the phone, with all my contacts and stuff... and it's 15Gb in size and there's nowhere to upload that monster. But I'll leave here the hexdump of the 'head' of the file:
