Basically yes. But if you don't plan on playing online there is no need to reflash the nand back to stock. Just continue along with the RGH and enjoy playing backups without a dvd drive.So are you saying hack the console and boot into Xell? And dump the dvd key and flash it on another drive, and then reflash the nand?
Also I guess I don't need to play online on the xbox 360 because they are ending support for it anyway
You're gonna want an HDD though if you don't have one, but since it will be an RGH console you're not stuck buying an MS branded drive or trying to find one of the older WD BEVS drives to flash. Any old 2.5" drive will work.
Read up on the RGH 3.0 process and give it a go if you feel comfortable soldering. All it requires is a switching diode, 10-20k ohm resistor, a raspberry pi pico, wire and some patients.
