OK, so now we need to know how to use that on a updated 3DS and not the ones with lower firmware. Has there been any progress? What would be needed to get into the system with say the actual FW on it?
Nope. There has been no new progress on finding any exploits on 6.x firmwares.
If there is any new exploit, this region free hack can easily be made to work. This is a non issue once new exploits are located. But... The chance of a new exploit being found is extremely small. Look at the ps3.
