Unbricking and Recovering A Western Digital My Book Live World Edition

How to Recover, Rebuild and Unbrick Your Western Digital My Book Live

When you Mybook live is just showing red light in front, or the world edition shows just some steady white lights in front, you know it's really bad.  You can open it up, find the J8 solder pads on the board, and then solder on some header pins.  Connect those pins to a Prolific USB to Serial port converter. Just connect Grnd, URX and UTX, and then start it up.

The Live edition has an onboard JTAG and UART port. Until now I don't know the pinout of the JTAG so be warned to overwrite data in the NAND.
The Pinout of the UART Port "J8" is as follows: (your J8 port may not look like this at all, but it may just look like a 2x2 pin pad with a white square around it.
Pin 1 = +3.3V
Pin 2 = URX
Pin 3 = UTX
Pin 4 = GND
Warning: do not connect directly to a serial Port, you will need a ttl level shifter like the "Max233" or "FT232R". Otherwise you risk to break the hardware.

The UART Port will give you access to the console and during the booting to U-boot.
You will be able to change U-boot parameters, this will allow you to boot anything you want.
I would recommand that you backup the parameters before playing arround.
Baudrate is configured to: 115200

Mercedes Benz Diesel CDI EGR Emulator Circuit Diagrams

Mercedes EGR Emulator Circuits for Electric Wahler EGR on Diesel Engine For any car fitted with a MAF you can't just block the  EGR valve  as the MAF detects the reduced airflow when the valve operates. If it fails to report this reduction the ECU throws a code, turns on the MIL light and engages Limp Home mode. The  EGR valve  is operated in varying degrees whenever the engine is in cruise mode. A circuit has to be designed that reduces the MAF output voltage whenever the  EGR valve  is called to actuate. Having seen a mod on another forum I decided to give it a go and installed it last night. The circuit is really simple. The  EGR valve  transducer is fed with constant 12v which is proportionately shunted to Gnd to create the potential to activate the transducer, to engage the EGR solenoid and allow hot gasses into the intage via the  EGR valve  in varying degrees. The MAF is in the cold air intake. the EGR gasses enter furt...

Fix: The Diagnostic Service Host service failed to start due to the following error. [ solved, no kidding ]

Lots of these Messages about the Diagnostic Service Host in the System Log On Windows 7/10 Machines Attached to A Domain The Diagnostic Service Host service failed to start due to the following error: A privilege that the service requires to function properly does not exist in the service account configuration. You may use the Services Microsoft Management Console (MMC) snap-in (services.msc) and the Local Security Settings MMC snap-in (secpol.msc) to view the service configuration and the account configuration.  The good news is that you can fix it using active directory group policy or the Local Security Policy and just adding a few things to the Local Policies.  Same fix applies to both Windows 7 and Windows 10.  To Fix this using any Policy, you must be running a Professional or Enterprise version of Windows. If you have Home Edition, sorry. Here's How to Fix It You see this in your system logs repeatedly, and its dragging down your computer and making it ...
