I've had a JTAG for years (jasper), it got banned about 2 years ago but I just reflashed it with a new hacked nand so it wasn't crippled anymore. I just booted it up for the first time in a few months and its crippled again so I grabbed xebuild and made a new hacked nand image (from my original, unhacked nand image which was taken before the jtag) and cpukey and reflashed with flash360. I updated to 17150 doing this, I just started up a game and my dlc isn't recognised so it seems the security is still broken. Why would a new flash not uncripple the system? I had the network cable unplugged, so it didn't connect to the internet and re-cripple that way. I keep my live profile on a usb but that shouldn't matter should it?
