E01: possibly a power supply problem E02: possibly a Network Interface problem (might be fixed by loosening the x-clamps) E03: possibly Power problem could be the PSU could be the GPU/CPU, somehow the console isn't getting clean power from the power supply. E04: Unconfirmed: There is a problem with the Southbridge Chip usually dealing with how it connects to the mainboard (cold solder joint/bridged solder joints) E05: CPU over heating - If you are receiving this error after disassembling your console make sure to all 8 of the heatsinc screws are tightened securely to the board/heatsink holes. E06: GPU over heating -ensure your x-clamps are installed properly. E07: RAM over heating E08: Unconfirmed: General I/O Malfunction, could be caused by an error with any of the I/O devies such as A/V port, USB, Hard drive, DVD drive, etc. over torquing of the AV or heatsync bolts can cause this error. E09: Unconfirmed: This can be caused by two completely different things either: A. DVD Drive Time out - Can be caused by problems with a firmware flash. This is also speculated to sometime be caused by a problem with the southbridge chipset on the motherboard based on how it connects to the DVD drive. B. GPU error, generally caused by a poor connection to the mainboard (cold solder joints/bridged solder joints) See error E18 for more information E10: Unconfirmed: CPU error, generally caused by a poor connection to the mainboard (cold solder joints/bridged solder joints). This can also be triggered by an error with the TSOP. E11: (not yet known) E12: Possibly a problem with temperature control E13: Unknown: could be caused by a short between the heatsink and surrounding capacitors E14: (not yet known) E15: (not yet known) E16: Unknown: Likely a cold solder join in GPU or Ram chips (see error E18) E17: (not yet known) E18: Error in the "Digital Backbone" (CPU/GPU/RAM), this is usually caused by a cold solder joint between the GPU and the mainboard. There are two theories to fixing this one deals with the "X" clamps that hold down the chips. The other involves re-Heating the chips. DO NOT attempt either of these if your console is still under warranty. If your console is still under warranty return it to the store where it was purchased or call MS to have it replaced. E19: Unknown: GPU Error this is usually caused by bridged solder points where the GPU connects to the mainboard. see error E18 for more detailed information E20: likely a Ram error, this can be caused by a cold or bridged solder joint on one of the Ram chips. ... E32: (not yet known) E33: (not yet known) E34: (not yet known) E35: over heating GPU possibly due to lack of thermal compound. ... E45: Unknown (possibly dashboard update related) E64: DVD Drive Error - Dvd drive timed out during reset :Wrong firmware, dvd is without f/w chip, etc. This can also be caused by the tray not being fully closed on boot. also it could mean that the Kernel can't be launched/signature in NAND Flash chip is broken It could be possible after bad update. This might also be caused by a bad SATA cable. E65: DVD Drive Error - Dvd drive is not DMA configured :Wrong firmware, dvd is without f/w chip, etc. This can also be caused by the tray not being fully closed on boot. E66: DVD Drive Error - Dvd drive pairing failure: DVD model, or version does not match that of the version expected by the dashboard. OR the firmware version on the drive is older then the firmware version expected by the dashboard. Make sure the DVD drive is of the same version originally included with the console and that it is using either the original firmware included with the console or newer. if drive can eject, read, and write under windows but errors on console, replacing original firmware should fix issue. E67: Hard Drive Error - Hard drive timed out during reset: It could be a problem with the Hard Drive itself or a problem with the internal connection to the hard drive, Try removing the hard drive and playing without it. E68: Hard Drive Error - Hard drive not DMA configured: It could be a problem with the Hard Drive itself or a problem with the internal connection to the hard drive, Try removing the hard drive and playing without it. Also this can be caused by a problem with the fans that make them draw too much power, it can also be caused if you have unnecessary accessories attached to the console like an external fan unit. Attempt to remove unnecessary accessories first, and then necessary components such as the hard drive and USB devices. If you have any case mods you may want to investigate those as well. E69: Hard Drive Error - Reading the HD Security sector failed: It could be a problem with the Hard Drive itself or a problem with the internal connection to the hard drive, Try removing the hard drive and playing without it E70: Hard Drive Error - Hard drive not found E71: Dashboard Error - Error within Xam.xex: possibly a dashboard update error, Check below in the "Console Reset Codes" for instructions. If that does not work there is no other solution and the console must be sent back to MS for repair. E72: Dashboard Error - Error within Xam.xex: Like a problem with the NAND flash E73: I/O Hardware Error - Couldn't calibrate HSIO Bus from edram: this error is likely caused by a problem with the Ethernet port or supporting control devices E74: I/O Hardware Error - HSIO related, could be crc error, or many things: There is high chance it's a scaler chip problem (the "ANA" or "HANA" chip near the AV cable connection) it can also be caused by a faulty AV cable so check that first. Microsoft covers this error under their 3-year warranty, this is availble to anyone who hasn't modified their console. contact MS to get a free replacement console before attempting to fix this yourself. Failing that this error In some cases it is a problem with the GPU and may be repairable by doing the x-clamp replacement (see error 0102) E75: Ethernet Error - Couldn't read ethernet phy vendor: Strange but sometimes caused by the DVD drive not being connected properly. E76: Ethernet Error - Couldn't complete ethernet reset: This error is usually cased by the Ethernet port's controller chip, a dead chip may not cause the error but removing the Ethernet controller chip does, it may also be caused by other Ethernet related problems. E77: Ethernet Error - phy request is already processing/reading reg failed/Failed to write reg: This error is sometimes caused by power problems with the RAM chips. It might be cause by a short between the heat sink and resistors or by more serious problems with the RAM. [more info] E78: Dashboard Error - AsicId check failed E79: Dashboard Error - Couldn't start xam.xex: probably a file system corruption, it could also be a problem with the Hard Drive itself or a problem with the internal connection to the hard drive, Try removing the hard drive and playing without it. E80: Dashboard Error - Wrong LDV version in NAND Flash: This is in new dashboard. You have the update but haven't R3T6 resistor. You can: -Downgrade to old dashboard, solder back the resistor and then update your xbox -If you have CPU Key, get current NAND Flash image and fix LDV (just add 1 up to latest kernel). (See error 1100)
