Err66 can be fixed. I'm guessing here that your box is modded and you're having a Samsung drive. This problem occurs with these 2 situations :-

1. The Samsung original firmware was using ms25 firmware version and the drive had been flashed with Xtreme4.0 firmware which use ms28 based firmware. The Fall/Jan Update is expecting ms25 drive but instead it detected ms28 so that it gives you ERR66.

2. The Samsung original firmware was using ms28 firmware version and the drive had been flashed with Xtreme3.3 firmware which use ms25 based firmware. The Fall/Jan update is expecting ms28 drive but instead it detected ms25 so that it gives you ERR66.

Also ERR66 can occur for this situation :-
3.If your dvd rom drive originally was a Hitachi drive and you changed it to a Samsung drive, when you do the Fall/Jan update it expecting Hitachi to be reported but instead it got Samsung drive being reported.

How to solve the problem? Simply flash it back to the original firmware or use the latest Xtreme5.2 hacked firmware if you don't have the original firmware.

If you want to flash back to the original firmware, just search for original ms25 or ms28 firmware and use your dvd drive key to patch to the original firmware and flash it back to your drive.

To solve the situation 3 problem. Just use the latest Xtreme5.2 hacked firmware for Samsung and spoof the drive to be Hitachi drive. This means you're using a Samsung drive but it'll report as a Hitachi drive.

That's why most of the shops that sells modded X360 will say to their customer not to go online as they know this kind of thing will happen. Most of the people that sent to me their modded X360 to be reflashed were having the outdated Xtreme3.3 firmware with Samsung drive. If you're having the Hitachi drive on the other hand this ERR66 will never happens as it always report as Hitachi.

These are the strings inside the dvdrom firmware that are being checked and must be reported accordingly to the drives itselves.

For Hitachi:-
HL-DT-STDVD-ROM GDR3120L0046
HL-DT-STDVD-ROM GDR3120L0047
HL-DT-STDVD-ROM GDR3120L0058
HL-DT-STDVD-ROM GDR3120L0059
HL-DT-STDVD-ROM GDR3120L0078

For Samsung :-
TSSTcorpDVD-ROM TS-H943Ams25
TSSTcorpDVD-ROM TS-H943Ams28

Others X360 that are not affected with this update is because the string being reported matched with what being requested by the update. For instance if an original Samsung drive is using ms25 and being flashed with Xtreme3.3 the update will success as it is the string is the same that is "TSSTcorpDVD-ROM TS-H943Ams25". Same goes to a Samsung drive that have originally ms28 firmware that being flashed with Xtreme4.0 and above will report the same string i.e "TSSTcorpDVD-ROM TS-H943Ams28". So there will be no ERR66 for them. I've tested this to confirm as my Samsung drive is originally flashed with ms28 and when I flashed it with Xtreme3.3, I got ERR66 and when I flashed to Xtreme5.2, the ERR66 gone.

The initial release of FALL(Nov 06) update had a bug that's why it affected unmodded machines as well and MS has fixed this a couple of days later. The ERR66 is in fact related to modded machines as they're being flashed with the wrong hacked firmwares. If LIVE is your LIFE than stay with unmodded machine.

So far, yes.


Yes.

As for now the answer is yes but not sure what will happen in the future.

Like I said before if you couldn't handle or face any consequences of being ban on LIVE in the future, stay with unmodded and originals. For me I wouldn't die if I don't have LIVE as I still got my LIFE.
