Goldcard SPL Downgrade Method; No Android-Phone and/or custom wires!

Goldcard SPL Downgrade Method; No Android-Phone and/or custom wires!

---

Good Evening,

I'd like to show you the easiest and noob-friendliest way to downgrade spl via Goldcard in order to install hspl and custom roms.

FAQ:

1) Q. What is a GoldCard? A) A specially formatted SDCard used to flash a stock rom to a phone when normal flashing methods do not work.
2) Q. Why would I need to make a GoldCard? A) To downgrade your SPL when you are unable to flash an SPL downgrade using other methods, or when your bootloader becomes "halfbricked" and will not allow you to flash using a PC and a USB cable.

What's so special about this guide?

- no custom wires needed
- no android/win-mobile needed
- all files included


The point why I wrote this guide is, that the previous guides often included unnecessary steps, they were sometimes inconsistent between each other, not very detailed, you needed to build yourself custom wires, and manually find the necessary files yourself. Here's an easy one.

What you need:

- Micro SD Card
- MicroSD Card reader
- Y-Cable USB
- USB Gender Changer

Files to download:

- Goldcard-tool

- My custom goldcard.img

- Your device-specific .nbh image.
You need to download a nodo rom for your device and extract Ruu_signed.nbh via Winrar. Rename it to


-Sparimg.nbh for Spark (Trophy)

-Spawimg.nbh for Verizon/CDMA Spark
Rom-download: http://forum.xda-developers.com/show....php?t=1427904
-SCHUIMG.nbh for Schubert (HD 7)

-MOZAIMG.nbh for Mozart

So let's start:

1. Make sure you're battery is above 50%
2. Format the MicroSD Card to fat32
3. Copy the .nbh Image to the MicroSD Card
4. Launch Goldcard Tool
5. While ignoring the cid box, choose "Load GoldCard.img" and select the goldcard.img you just downloaded
6. Press "Patch MMC" and wait for confirmation
7. Unplug the MicroSD Card
8. Connect the Y-Cable and the USB-gender-changer like shown in the picture
   
9. Connect the MicroSD-Card
   
10. Connect your phone
    
11. Connect the y-cable to an ordinary usb port
    
12. Hold Power+Camera+VolumeDown until the USB Host Mode appears
13. Wait about 30 min until the update completes. The phone may reboot a couple of times.
14. After the update completed, unplug your phone and reboot

Now your spl should be downgraded. I hope I could help you out.

Cheers, Klaus.
