This happened a while ago actually. I was updating my R4i Gold with the latest patch to make it compatible with the latest 3Ds update. The flash utility was written in a way that you press A to flash the new firmware. On instinct, once the patch was done, I pressed A again to exit the Utility...except it started flashing again! That time it flashed successfully, but from that point on, it just...stopped working. By that, if I put it in my 3ds, my system will hang indefinitely. It's a bit of a weird hang though. The Ambient sounds still play, and the click sounds still work if I click on something...the little icons still spin around on the top screen. I just cant do anything...at all. Nothing functions and I have to force power off the 3ds. I'm almost positive that I have a dead cart on my hands now, but before I chuck it down the can, I just wanted one more reassurance that...just in case there was SOMEthing I could do. Thanks for listening to me.
