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://xdaforums.com/showthread.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?

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.

Finally got it fixed. As GC100 is similar to S3, downloaded efs file for S3 flashed it via odin through bootloader and voila... attaching the file for reference if anyone else gets into trouble! :p

Shouldn't I be awarded king of all screw ups!? Tried to flash a Rom for S3. No problem with few tweaks, didn't work however, flashed stock gc100 now touch screen not working. factory reset with stock recovery, cwm recovery still touch not responding... flashed 3 parts stock rom + efs, flashed 3 part stock without efs, flashed 4 stock roms 1 package, still touch not working...

It's closer to an s4 than s3 but if you wanted a galaxy cam phone, they already make the s4 zoom.

I don't want a phone and I'm aware of S4 zoom. Its just that I can't sit and do "nothing". Well that's why i keep playing around (and always get into trouble :p) :D Well getting the touch replaced as that's the only way. logcat says -1v for touch which means I've fried the touch digitizer. hahah (Still in warranty, unrooted and resetted the counter with triangle away) :D

Its the same specs as an international S3, but it's got lower screen resolution. Its definately not like an S4 at all.

Definitely wasn't talking about hardware specs just the software.

Either way, it would be better to compile a build using the phone as a base and making the necessary changes than attempting a direct port.
