Need help!

Hi everyone ,
today i’m bringing you this problem i had.
i installed XexMenu 1.2 on my rgh/jtag xbox
and dashlunch and also disabled the liveblock
xbox asked me for an update to connect to xboxlive so i updated it when
then when the update is done the xbox went off and then came back on and it stuck it won’t even launch ( i mean i can turn it on but…)

You can’t just update an RGH like that you. You will need to buy a device to flash it back to a modified nand or pay to have it done. If you can still boot xell by turning on the console with the eject button you have another option but more than likely you can’t do that.
