I was wondering if you can go buy a brand new 360 and have it RGHed? I was reading and was still fairly confused thanks for reading and replaying.
Only xboxs with dash 7371 or lower can be JTAG'd, any Xbox besides Xenons and Zephyr can be RGH'd. Even the newest slim.
Zephyrs and Xenons CAN be RGH'd. Xenon consoles are only meant for DVD key retrievals though. Nobody has successfully booted a dashboard image via RGH though, hence for XeLL recoveries only. Zephyrs can be RGH'd too. 75% of them work with RGH1 or just don't glitch at all. Mainly due to the stress on the console when glitching. But it CAN be glitched and successful.
I know the deal with Zephyrs and Xenons, I just wouldn't recommend it to someone... He asked what consoles can be RGH'd not for DVD key retrieval, so no point even suggesting they can be done.
Like I said Zephyrs are 75% glitchable. I personally have never had issues with RGH1 Zephyrs. EDIT - Plus the RGH process is not about dashboard images. It's still RGHing it
