I bricked 2 of mine before they altered the exploit. I did the exact same thing this time but used a wire (you NEED to use a wire or a paperclip with electrical tape. Wire is preferred though, I stripped an ethernet cable since there's like 7 wires in there total. Strip it to copper on both ends just enough to get contact and follow the method) but anyway, I have s-off now and it's beautiful. I also found that you can restore the sdcard after corruption, just create a new partition table and then repartition it. ) Hope this helped.
Proof of sdcard restore:
Also proof that I'm not turbo-tarded:
