1-DISCLAIMER
============
What you are going to do may be:
-Dangerous for your data: May be you have to make a hard reset and lost all your data and applications.
-Dangerous for your Hardware: Althought none bad have happened to me, I cannot assure that these modifications are sure for your hardware.
-Illegal: Probably you are going to violate HP, Broadcomm, Microsoft and Dell Licenses, do it only as an "academical proof of concept" and revert your machine to its original state as soon as possible.
-It is only tested on an Axim X51v ROM A01 Spanish language. I cannot assure that it works on other machines, languages or versions.
-It is a unofficial instalation and have not been fully tested. several profiles may work, others not.
I cannot accept any responsabilities for any damage, lost of data, or what these companys could reclaim you.




2-BACKUP AND PREPARE
====================
Althought the process is reversible, something might fail. You have to do at least these data backups before try it:
-Export the full registry branch HKLM
-Make a full backup using the program included on your X51 or a third party program
-Turn off security prompt with Ctitanic SetSecurity.




3-MICROSOFT BLUETOOTH STACK REMOVAL
===================================
You have to use a registry editor compatible with Regedit V5, like Resco Explorer (it exists a demo version) or PHM Registry editor (Freeware)
-Delete Registry key HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\Transports\BuiltIn\1		
-Delete Registry key HKEY_LOCAL_MACHINE\Services\BTHIDSVC		
-Delete all the values under HKEY_LOCAL_MACHINE\Drivers\BuiltIn\BTControl

4-WIDCOMM BLUETOOTH STACK INSTALATION
=====================================
Manually:
	-Copy all the files under "Windows files 1.7.1.34" folder to \Windows on the X51
	-Copy the file under "Startup" to your Startup directory,  that is, \Windows\Startup on English machines or whatever it names on other languages.
	-Copy the file under "StartMenu\Programs" to your Start menu programs directory directory,  that is, \Windows\Start Menu\Programs on English machines or whatever it names on other languages.
	-Execute PlatformV037.reg , This file contains all the registry entries needed for the new stack.
	-Soft reset device
Semi-automatically (this method is not fully tested and is under development):
	-Copy BroadcomV037.ARMV4.CAB to somewhere on your device. Locate the file with file explorer and execute.
	-Install to default directory.
	-Locate and execute \Windows\PlatformV037.reg
	-Soft reset device
