Hi,
I am having a similar problem as the OP.
- Latest Sony FW on the prs-500
- Ran UF 2.1
- Press 5 - success
- Press 6 - failed (error while flashing partition)
- Power off\on - Stuck at "Starting up"
- Reset 10x - success
- Screen at "Updating Firmware now..."
- Cannot trick updater into enabling "Update" button
- Ran ebook.py script - results:
C:\Users\me\Desktop>ebook.py um normal
Sony Reader utility 0.41 (c) 2006 Igor Skochinsky
Traceback (most recent call last):
File "C:\Users\me\Desktop\ebook.py", line 616, in <module>
b = Ebook()
File "C:\Users\me\Desktop\ebook.py", line 244, in __init__
self.dll = windll.ebookUsb
File "C:\Python26\lib\ctypes\__init__.py", line 423, in __getattr__
dll = self._dlltype(name)
File "C:\Python26\lib\ctypes\__init__.py", line 353, in __init__
self._handle = _dlopen(self._name, mode)
WindowsError: [Error 126] The specified module could not be found
I'm a perl guy.

I don't know which modules I'm missing, nor how to install them. If anyone could help, I'd really appreciate it. Let me know if I'm on the right track in bringing my reader back to life.
