Create goldcard

Hi;

I will make a gold card for downgrade my 1.72 unbranded DHD (didn't downgrade when i did without a creating goldcard with this procedure). So which procedure must i do?

First one uses a "Goldcard helper" program and second uses SDK. I think its easier with helper program.

1- This is in the Telus DHD-Rooting and flushing guide:

-Create a Gold Card:

* Install GoldCard Helper from the Android Market,

* Run it and make note of the value listed after Card:mmc2, Reverse CID. It should be a long series of numbers and letters. (make sure to use mmc2, the default copy to clipboard copies mmc1 ..)

* Visit this page (i can not write because i am new in XDA), enter the new copied number and create your goldcard image, which will be e-mailed to you.

* Save the file attached in the email to your PC.

* Install HxD Hex Editor on your computer, from the "Step 4 - Gold Card" folder.

* Run HxD Hex Editor. ("Run as Administrator" under Vista and Windows 7).

* Go to the Extra menu and select Open Disk. Under physical disk, select Removable Disk (your microSD card), uncheck Open as Read only and click OK. Note that you should select physical disk NOT the logical disk. This is important!

* Go to the Extra menu again and select Open Disk Image. Open the goldcard image that you received by email.

* Press OK when prompted for Sector Size (selecting 512 (Hard disks/Floppy disks)) and click OK.

* You should now have two tabs - one is your removable disk, the other is your goldcard image.

* Click on the goldcard image tab. Go to the Edit menu, choose Select All then select the Edit menu again and select Copy.

* Click on the Removable Disk tab. Highlight offset (line) 00000000 to offset (line) 00000170 (including the 00000170 line), then click on the Edit menu and select Paste Write.

* Click on the File menu and select Save, accepting the warning.

* Your Gold Card SD card is completed.

Step by step instructions

* Format the microSD card to FAT32 format.

* Put the microSD card in your device and boot it.

* Ensure you have unzipped the SDK, then open a command prompt to the extract location. Change to the 'tools directory.

* Enter 'adb shell cat /sys/class/mmc_host/mmc1/mmc1:*/cid' and press enter. You should get a very long number which looks like this: 532600bd227d9c0347329407514d5402.

* Visit this page, paste in your number and reverse it. In our example the result would be 00544d5107943247039c7d22bd002653.

* Visit this page, enter your reversed number and create your goldcard image, which will be e-mailed to you.

* Open the HxD hex editor. If you are using Windows Vista or Windows 7, you must run the application as administrator.

* Go to the 'Extra' menu and select 'Open Disk'. Under physical disk, select Removable Disk (your microSD card), uncheck 'Open as Readonly' and click OK. Note that you should select physical disk NOT the logical disk. This is important!

* Go to the 'Extra' menu again and select 'Open Disk Image'. Open the goldcard image that you received by email.

* You should now have two tabs - one is your removable disk, the other is your goldcard image. Press OK when prompted for 'Sector Size' (selecting 512 (Hard disks/Floppy disks)) and click OK.

* Click on the goldcard image tab. Go to the 'Edit' menu, choose 'Select All' then select the 'Edit' menu again and select 'Copy'.

* Click on the 'Removable Disk' tab. Highlight offset (line) 00000000 to offset (line) 00000170 (including the 00000170 line), then click on the 'Edit' menu and select 'Paste Write'.

* Click on the 'File' menu and select 'Save', accepting the warning.
