Hi, a friend flashed his 360 with xtreme4.1 but he didnt backed up the original firmware, now he wants to flash it with 5.2, so is there a way to restore the original firmware and then flash it with 5.2 or a way to flash it directly from 4.1 to 5.2? thanks

your key is inserted on the f/w that is on there now so you can just dump the original(4.2) firmware from your 360 and insert it into 5.2

with firmware toolbox?

you can use firmware toolbox or just use the "make xtreme firmware" included with 5.2

so i just have to dump the 4.1 firmware and rename it to orig.bin, then place it in the Make Xtreme Firware folder and run the batch file?
