Yes, you can exploit any console. You won't be 'JTAGing' your console in any way, you'll be exploiting it using an ICB method. You won't be running a rebooter either, just running a modified dash. For anyone interested, the modified dash has been finished for a good week or more now but hasn't been released. You might be waiting a while or maybe just not getting one, after all, LibXenon promotes legal homebrew development, NOT piracy, which from the sounds of it, is all OP wants his console for. Not releasing this dashboard would prevent the piracy because everyone wanting it will be too stupid to make one for themselves, yet the people smart enough to make their own are also smart enough to keep it to themselves.
