i have successfuly unbrand my vodafone trophy using my htc HD2 as disk drive and GoldCardTool.
Here simple schematic and tool to unbrand all htc 7 Device with any device detected as usb mass storage.
this also work with a windows mobile device or a card reader.
1-Found the CID of your card.
insert your micro sd into an android device (i've do this on hd2)
connect it to your computer as disk drive with usb debug on
then press get cid into Gold Card Tool.exe
we need reversing CID to create img .
go to the link provide by Gold Card Tool.
add your mail, the CID and select Windows mobile 7
Press the Generate button
the goldcard.img is send to your mail box.
Load it to Gold Card Tool
select your android storage letter & press patch MMC.
3-Found HTC original Rom for your Device
Extract exe with winrar then rename Ruu_signed.nbh
-Sparimg.nbh for Trophy
-SCHUIMG.nbh for Schubert
- MONDIMG.nbh for Mondrian
- MOZAIMG.nbh for Mozart
copy it to your freshly created goldcard.
4-connect usb cable except the one for the wp7
boot your device into usb host mode(volume down + camera on Trophy)
and connect the last usb cable.
the screen of your wp7 look like this if all work.
with this you can flash official HTC rom on your Vodafone ,O2,Orange...operator device.
i have also flash Spl from official rom to my vodafone Trophy by this way but always a vendor id error with the official updater!!
i'm searching why!
tested on Trophy,hd7,Mozart,HTC Surround.
