Hard Brick Prevention and developing UnBrickable SD

---

Some general rules:
It is not recommended to flash bootloaders on your device unless necessary. When flashing bootloaders, make sure the model number matches the device you are flashing. Also, always use a new cable without any wiggle room or cable damage.

To get into download mode to use Odin or Heimdall:
Remove and replace battery.
hold Volume Down & Home then press power while continuing to hold power.
You can now use Odin or Heimdall to flash a stock ROM package.

The Fix for Hard Bricks:
In the event that you cannot get to download mode, please contact me. I am developing a boot-from-sdcard fix for bricked Galaxy Cameras based on the methods used in i9300 here: http://forum.xda-developers.com/show...php?p=34139922. The hardware mod must be located to boot Odin Mode (Loke Daemon) the SDCard. JTAG will not work on Exynos 4412 devices.

Why will JTAG not work on Exynos 4412? Also, if i wanted to view UART output from the GT-I9300, is all i need a linux box with a cable like this?

--UPDATE: looks like you did a video for the Captivate on your UART jig. Taking a look now for resistor values regarding the GS3, perhaps an oscilloscope would help here?

There is no UART output on USB on this device. Also Exynos4412 JTAG is usually disabled except for the Nexus10.

Bummer, I just saw that it looks like you had to interface directly to 2 board pins on the Galaxy Camera to get UART i imagine it will be similar on the GS3.

Why would you do that when Adam gave us a specific root method for our GCams? You should probably post this in general section. I sure hope someone can help you out. It would be a bummer if you lost your camera

Good Luck.
