make a goldcard

***NOTE: All credit goes to the devs, I am not responsible for you bricking your phone!

1. Download QMAT
It’s a demo version so will only can open for 10 minutes.

2. Format your memory card to fat32. Please keep in mind some card does not work.

3. Search in your android market for ‘Terminal Emulator’

4. type ‘ cat /sys/class/mmc_host/mmc1/mmc1:*/cid ‘ without the quote sign.

5. Note that code down on a notepad or something. Make sure everything is noted correctly.

6) Go to QMAT site, download QMAT 4.36
7) Extract the file, double click on qmat.exe
8 ) Click on Cyptoanalysis Tools > Crypto Toolbox
9) Look way below, there is a text box (beside “Reverse String” button. Key in the cid number you’ve got earlier
Click on the “Reverse String” button, the result is reversed…
Example: 532600bd227d9c0347329407514d5402
10) Copy the reversed cid
11) Go to QMAT again to generate your goldcard (this is free for G1 phone, Thanks to Viper!)

12) Enter your email. For the CID, enter the reversed cid you’ve got earlier. However you need to replace the first 2 characters to 00.

Example: From “532600bd227d9c0347329407514d5402” to “002600bd227d9c0347329407514d5402”

13) click Continue and you will receive the goldcard.img via your email.
14) Go to your email, download the goldcard.img and save it to a directory first.
15) Now, download HxD Hex Editor for this site

16) Install and launch HxD Hex Editor program
17) Go to Extra tab > Open Disk. Under Physical disk, select Removable Disk (Must be your SD card), uncheck “Open as Readonly), click OK.

18) Go to Extra again, Open Disk Image, open up goldcard.img which you’ve saved to a directory earlier.
Now, you should have two tabs, one is your removable disk, the other is goldcard.img. Press OK when prompted for “Sector Size” 512 (Hard disks/Floppy disks), click OK.

19) Click on goldcard.img tab. Go to Edit tab > Select All, edit tab again > copy.
20) Click on the “removable disk” tab. Select offset 00000000 till offset 00000170, click on Edit tab and then Paste Write.
21) Click on File > Save. You may exit this program

Now, do a test to see if your SD card is “compatible”

Disconnect the USB cable connected to your SD card, then plug it back again. Go to My Computer, you will see your SD card (E.g. “Removable Disk ( F” ), double click and see if you can access it. If it prompted you to format, then forget about this SD card, don’t think it will work. After trying for days, I ended up buying a Kingston 2GB card.
