Please read the first post in this thread to acquire the latest version of the patch!!!!

For historical reasons, I keep the original post here so that the context of this thread isn't lost. Reading it is NOT needed for anyone; just follow the link above!

The title says it all :)

Just trying to swap the MS BT stack on my x51v into a Widcomm one, extracted from a WM2003SE x50v upgrade (say, this one: http://support.dell.com/support/down...&fileid=137112 ).

As the BT hardware may be exactly the same as on the (by default WM2003SE) x50v, it may not be impossible to disable the MS stack in the Registry (it's referenced in many, system-level, mainly Servicing-oriented registry entries) and use the Widcomm one instead.

Has anyone tried this? I've run a quick search here for 'dumprom' (the infamous tool ( http://wiki.xda-developers.com/index...gename=DumpRom ) to extract individual files from .nbf files - see http://www.firstloox.org//forums/showthread.php?p=39838 for more info; unfortunately, it seems it can't extract files from Dell's .IMG files) but couldn't find anything.

The IMG file is encrypted. Based on the repeating pattern, it may be a simple 64 byte-key XOR encoded file, which is very easy to reverse.

I don't want to waste some hours on this hack if anyone has tried it before and failed at it.

EDIT (March 30):
A new thread has also been opened to post everything about the development of the project. This one is becoming huge and it starts to become impossible to find anything.
