Microsoft Xbox Serial Number Lookup
Xbox One Serial Number Checker Software

I just bought a xbox one x brand new but when I opened it look that has been used because of cosmetic imperfections, I checked the serial number in the box as same with the console and the information menu, all of 3 matches, do you think is new? Is possible for someone swap/change the stickers of the serial numbers in the box and the console? Sorry for the english. If they have several consoles in stock, it there a way to check the serial number on the box to determine when the console was manufactured? I’d rather buy one that was made more recently as opposed to one that has been sitting there since November.

History of Xbox 1.5

There has been no conclusive evidence pointing to their existence, and all 1.5 sightings to date have turned out to be 1.4 boards.They possibly never existed^{[citation needed]}, but will otherwise be very rare. Production was halted and 1.4 was produced again^{[citation needed]}.

Identifying

While not definitive, here are some ways to help identify the revision of your Xbox.

The serial number looks like this:

LNNNNNN YWWFF

L is the production line
NNNNNN is the number produced that week
Y is the last digit of the production year

Note, this table contradicts the previous table.

DVD Drive

There are four retail drives known to be used by Microsoft in the retail version of the console.Any Xbox DVD drive can be used in any retail Xbox.

List of Xbox DVD Drive manufacturers

Thomson (Xbox 1.0, 1.1)
Philips (Xbox 1.1 and above)
Samsung (Any)
Hitachi-LG (8050L)(mainly 1.6?)

THOMSON TGM600

The first manufacture is sadly also the worst of all Dvdrom drives manufactured for the original xbox.It has a Cirrus Logic CL-CR3710-60EC-F as its main controller and a 8/3062 HD 64F3062F25 16bit H8/300H secondary samller MPU,at 25Mhz Unkown sofar if there is external flash or if its inside the Cirrus Logic IC.

SAMSUNG SDG605

The Samsung drive is a very popular DVDrom drive for its compatibility for most media types and better quality laser. There are 2 mayor revisions found for this manufacturer

X00603-005 Plays CDR
X00603-006 Wont play CDR

The DVDrom drive is using the MT1358E (MT1359E is the 360 Sata version) from Mediatek, and has a 39SF020A flashrom.If the firmware from this drive is applied to a SAMSUNG 616T or 616F PC dvd drive it will behave as a Xbox one, modified hardware will allow for tray state and eject to work.

Commodore4Eva released a hacked firmware for this drive which enables modified backups to work. There is also a '0800' firmware for this drive which allows to dump the entire SS. The firmwares are not linked here for legal reasons.

Original firmware for the similar PC drive SD-616F (F105).

PHILIPS VAD6035/21

Also named: VAD6011/21 appears to have no brand or part number on its large main controller, might be Cirrus Logic based on its size and use of a Philips secondary smaller MCU. flash might be a 39SF020A from SST. The laser ribbon cable connector is different for its various revisions, a detail one must take into account when swapping controller boards.

There should be a tutorial on how to convert a PC DVD-ROM drive Pioneer 500M with the Philips firmware to be an Xbox DVD-ROM drive.

HITACHI-LG GDR-8050L

This DVD-rom drive, most commonly found in Xbox 1.6 and 1.6b is capable of reading DVD-+R, DVD-RW and CDRW media, but fails to boot most CD-R discs source: xbox-hq.com Hitachi-LG GDR-8050L DVD Drive In Xbox.

MiniTool Partition Wizard 9 PRO - Authentic activation key - Full version -Sale. AOMEI Backupper Professional v6.2 - 100% Full Version - Lifetime license key.

The latest manufacture for the DVDrom drive probably used a Panasonic MN103S89FDA for its main controler, appears to have no external flashrom.with this firmware and modified hardware for Eject and traystate, a LG GDR-8163B or LG DRD-8160B might act as a drop in replacement after altering either case.

On 30 January 2006 TheSpecialist posted at xboxhacker.net that he successfully flashed a Hitachi drive to boot a copied game on an unmodded xbox: breakthrough: XBOX 1 firmware hacked !

There is also an IDC Script and information about the firmware which was recovered from xboxhacker.net / old forum posts.
