I have a Model B Raspberry Pi revision 2 (512 MB of RAM) that previously ran XBian Release Candidate 2. Perhaps after an automatic upgrade, the unit developed some problems. Two days ago XBMC failed to load a station in the USTV Now add-on. I then tried to run USTV VoD. The system locked up. It would not respond to the USB wired keyboard input nor the Yatse remote through the WiPi connection.

I had to remove the power from the unit to attempt a reboot. The reboots always fail. I see a steady red power LED and two flashes of the green LED. There is no video output, not even a cursor or any characters on the screen.

Then I decided to do a clean install. I downloaded the XBian_1.0_RC_3_Raspberry_Pi.img.xz file. From that I extracted the XBian_1.0_RC_3_Raspberry_Pi.img file. I removed the SD card (apparently an 8 gigabyte class 6 with a Raspberry logo) from the Raspberry Pi and reformatted it in my desktop computer using the SDFormatter version 4.0. (Format options: full overwrite and format size adjustment on.) Then I wrote the XBian Release Candidate 3 image file to the SD card using Win32 Disk Imager version 0.9.5.

(I expected to see some files in the image with a current date but the files have dates such as 7/20/2014 and 7/21/2014 for some reason.)

Using the newly-written SD card, I attempted to boot the Raspberry Pi. Again I see just two green flashes and a steady red power LED. No video. There is also no LED lit on the WiPi wireless module. The power supply has a capacity of 1.8 amperes and the voltage on pin 2 of the GPIO is 4.99 volts DC.

I only have an analog video monitor. Pressing the USB keyboard's 4 key to switch to a composite NTSC video output mode has no effect.

I removed the SD card from the Raspberry Pi and put it back in the card reader attached to a desktop computer. I commented out the "initramfs initramfs.gz 0x1000000 line" in the config.txt file on the SD card. The Raspberry Pi still will not boot.

Any suggestions? What can I do to get the Pi to boot?
