Hacking R4 Not loading

[FaRReR]

Take out the MicroSD and blow in the slot which the MicroSD goes in, and then blow in the slot which the R4 goes in.

If that doesn't work, then your r4 is dead.

It must be dead. And no, it isn't fake, it wouldn't make quiet any sense if it was fake when it did work before. It just refuses to now, I just tried to update the firmware, which failed. I inserted my old firmware, it failed. I format my microSD and tried both old and new firmwares, which failed. All this leads to telling me, it mush be broken. I've already bought a new R4 but it is a clone, I wanted to buy it for my friend, but it seems that isn't happening since I can't fix this one. It will not load, it stays on "loading" and does not load. Let me repeat that it did work before, just not now. I've tried several other MicroSDs, none have yet to make it work. I've done every possibility I can to fix it I believe, it must have died. So should I bring this as the conclusion?
