Create an Sd Gold Image fo your card

How to Create A GoldCard

In the world of mobile device hacking there are several very well known, terms, most of which are things that hackers, regardless of platform are familiar with. Some of these include, S-OFF, unlock, root, and gold card. The last one was born several years ago, and allows members to flash things from a specially formatted microSD card, also known as a gold card, to any device when the regular flashing methods do not work.

In the world of Windows Phone 7, the gold card method can actually be used for things such as downgrading the SPL version of a device when a downgrade cannot be flashed via RUU or PC. However, this method tends to be overly complicated, with one of its variants even requiring the use of an Android device or even a Windows Mobile device for the process. Well, if you are pure WP7 and don’t posses any of the aforementioned devices, XDA member MarysFetus decided that he would provide a guide that involved the use of neither of them.

The method actually involves using a specialty three pronged cable, a USB gender changer, and a microSD card (and a reader). The dev has provided a very specific guide that guides anyone on a step-by-step journey to get the device flashed in no time. The dev also provides any and all required downloads in the thread, so it easily becomes your one-stop shop for all your gold card needs.

Please leave any feedback if the thread itself is useful or if you would like to add anything to this already fantastic guide.

What’s so special about this guide?

- no custom wires needed
- no android/win-mobile needed

HTC Phones made in early 2011 and prior require a ‘Goldcard’ in order for the user to downgrade and eventually root or unlock the phone. This is a simple guide with 13 easy to follow steps of how to make a Goldcard for your phone. I have taken the content from my original post at forum.xda-developers.com, and revised and updated the guide to give you more and easier options to be on the way to root your phone.
GUIDE – How To Create A GoldCard:
Preliminary Step: Take a deep breath, and be patient. This is a simple guide, but can be frustrating, especially if revskills is down. Any damage you do to your phone is your own responsibility, and will only happen if you aren’t patient or do not follow the steps properly.

1. Format the microSD card to FAT32.
***Note: THIS WILL WIPE ALL THE DATA ON YOUR SD CARD - make a backup first!

2. To find your CID:

Use Goldcard Helper from the play store: Found at

OR
Open ASTRO File Manager which can be downloaded from market
Navigate to sys/class/mmc_host/mmc2/mmc2:0001 (you’ll find that 0001 will be different on your device)

Long press on the CID file Select Open As and then Text Select File Editor

You’ll be given a long number, make a note of this.

***NOTE that you might need mmc1 or mmc0, depending on your SD card.

3. Write down the ‘Card:mmc2, Reverse CID’ value, making sure to use mmc2 and not mmc1 (unless your device requires otherwise)

4. Go to this page and follow the links to the goldcard generator page, then enter the reverse CID and follow the instructions (they will email you the goldcard img file)

NOTE: If the Revskills website is down (it often is) download gcard.exe and follow these instructions and type the following to generate your own goldcard.img:

1. Unpack gcard.exe to C:\gcard
2. Start CMD as administrator.
3. Type, then press ENTER after each command:
cd c:\gcard
gcard.exe -r -c 00CA00E2EBD41C804732335553445303 -o Chiffinske.img (name it whatever you like)

Be patient, someone will help you.

5. Launch HxD hex editor (download ) on your computer by right-clicking it and clicking ‘Run as Administrator’.

6. Mount your SD card to your computer - MAKE SURE IT IS FAT32 FORMATTED!

7. Go to ‘Extra’ menu > ‘Open Disk’

8. Select Removable Disk (which should be your SD card) under Physical Disk (NOT LOGICAL DISK!), uncheck ‘Open as Read-only’ and click OK.

9. Go to the ‘Extra’ > ‘Open Disk Image’ again and this time open the goldcard image that was sent to you.

10. Select ’512 (Hard disks/Floppy disks)’ as the sector size when prompted and click ‘OK’.

11. In the goldcard image tab, go to ‘Edit’ > ‘Select All’ and then ‘Edit’ >’Copy’.

12. In the ‘Removable Disk’ tab, highlight offset (line) 00000000 to offset (line) 00000170 including the 00000170 line and go to ’Edit’ menu > ‘Paste Write’.

13. Click ‘File’ > ‘Save’ and accept any warning that you get.

Congratulations – You now have a goldcard!

You can now downgrade your phone in order to flash custom ROMs
