Documentation of Xbox One EXXX (E201, E105, etc...) error codes and their meaning, plus possible solutions
Click here to contribute new error codes information
Xbox One shows two types of critical error codes when the console cannot boot. This list aims to become a comprehensive documentation of these codes, and advice or tutorials explaining how to repair consoles with those errors.
- NOTE 1: Some of these codes might be shared with Series S/X but the meanings might be slightly different! For example, Series S/X uses SSD, not HDD. Please always double check.
- NOTE 2: Some official documentation exists (https://support.xbox.com/en-US/help/errors/error-code-e105) but usually the explanations are just vague or completely inaccurate.
There are only 2 types of error screens that show EXXX codes.
Screen Type 1:
If you see this screen type, it means that the Operating System has, at least, been able to start. But then it found some problems.
The Operating System can have started just from eMMC NAND memory (in the case of Xbox One) or from the SSD's hidden partition (in the case of Xbox Series)
The Operating System might have also loaded the full Operating System files from the HDD/SSD before failing.
Screen Type 2:
If you see this screen you are screwed. This is a bootloader screen, which means the OS didn't load. This means the bootloader was not able to read the basic OS files from the eMMC memory (in the case of Xbox One) or from the SSD's hidden partition (Xbox Series), or they were corrupted or some file missing.
These are error codes that happen earlier in the boot process or in the Xbox's HostOS.
Update Failed / DVD drive not paired This error typically occurs when a paired DVD drive is not present, and will prevent the ongoing system update from finishing.
Solution: Repair the original DVD drive that came with the console.
Related to the update process - several different possible causes Solution: Perform an OSU and check that the disk is not damaged. Replace if damaged.

No HDD was found / Corrupted file in the HDD / Corrupted file in the eMMC This error seems to occur whenever an OS file cannot be found or is corrupted, either in the eMMC, or in the Hard Disk.
- Solution 1: Plug an HDD into the sata port. Check that the sata port is not damaged.
- Solution 2: eMMC might be damaged and failing to read properly. Try to dump eMMC, and then replace eMMC with a new part. Restore dump into the new eMMC. VIDEO
- Note: The original eMMC must be readable enough to get the console's certificate. The rest of the memory is not necessary, but an Xbox One won't work without its factory-issued unique console certificate.
No HDD was found / Corrupted file in the HDD / Corrupted file in the eMMC
This error seems to occur whenever an OS file cannot be found or is corrupted, either in the eMMC, or in the Hard Disk. (Almost like E105) Solution: Same as E105

Invalid harddisk (Xbox One) or invalid SSD (Series S/X).
Solution: This error appears when swapping the hard disk (HDD) or solid state disk (SSD) of the consoles. It is unknown why some drives are invalid even after copying the files from the original drive. It might be a speed/bandwith issue (in other words: the console detecting that the disk is not fast enough) or maybe the Xbox's only accept disks from specific manufacturers (specially Series S/X and the SSDs, Xbox One seems to accept almost any hard disk (has someone tried to put like a 100Gb old HDD or something? It might trigger this error code.). Replace the disk with another one, preferably from the same brands that Microsoft uses, or even a disk from another donor Xbox

Generic catch-all error code. Solution: Unknown.

The last update was interrupted.
Solution: Perform an OSU
Unknown/Pending Documentation
An ongoing system update failed because of software reasons
Solution: Reboot the console and try again. If the error persists attempt an OSU. If other error codes appear, try the solutions for those instead.

Software error? Seems to happen sometimes whenever a factory reset occurs.
Solution: Reboot the console and try again.

Apparently, E3XX codes exist. They seem to be rarer to come accross. Their meaning is partially unknown
Presumably, when rogue Xbox One Internal devkits are banned, they present an irreversible E20X error code. (Their certificate might be wipped, according to @TitleOS)
