its not as easy as 'i have a jatg so i can host lobbies'
to clear a few things up, yes you can go online with a jtag (not RGH i will get to that)
aslong as its a jtag kernel on the latest dashboard, (glitch build via - runner)
yes YOU WILL GET BANNED, but with the original jtag you can change the keyvaults / KVS' this is the console id. (i do jtags/RGH installs, so always have a few handy. there is no set time of how long you will get to play on live for, 5mins - 48 hours. who knows. i have had the latter before now. (shared kv's last even less)
an RGH CANNOT!! go online with unsigned code. it will be banned instantly, with no way as yet to change kv.
if you have heard about an RGH going online your not getting the whole story. the RGH will have a dual nand, one original image, and one glitched. the original nand can connect to live. however the rgh (unsigned code nand) cant go online. mainly due to scripts to blocklive:
if the blocklive option isnt used, and the console connects to live, the original nand will be banned also. althought 2 different nands, they both share the same kv.
moving on to modded lobbies. unless someone gives you a patch you will have to do alot of studying on the subject of cryptology. somehow find the PUB/PRI keys for the game you want to mod. then script from there.
good luck with that. the keys are avalible, but unlikely to be released.......... (no i dont have them, nor have i ever tried to aquire them) sometimes you can want to hack a game so bad that your attention is stolen, and you then become fascinated by the whole security put in place. its more fun to explore the file systems and uncover secrets of the system than to mod the game itself
Somebody knows theyre shit. LOL
