Here are my notes on upgrading the Cingular 8125 (HTC Wizard) to
Win 6.5 mobile using Win 7 (Vista)
I had been explicitly following :
and then for Vista (actually I have Win 7)
The CID and SIM had been unlocked.
The Drivers for Windows Vista x32 were installed.
VISTA_RUU.zip was downloaded and unzipped.
Everything was fine and then I ran Vista_ROMUpdateUtility.exe.
It goes through the “Viewing ….” and then the “Validating…”
The first acknowledgement screen comes up and is answered.
The second acknowledgement screen comes up and is answered.
The third screen comes up the present device information.
You get ERROR :FILE OPEN
After exiting the install, it apparently leaves a process running on
the PDA with the USB port locked, because thereafter I get the
ERROR : CONNECTION message. The only thing that works
is rebooting the PDA into boot mode again which frees the USB
port issue and brings it back to the file open error message.
The problem all stems around the fact that the VISTA_RUU.zip file
does not have a nk.nbf file. Trying to find the correct nk.nbf file with
the correct 2.26 update is disconcerting, since you don’t want to turn
your PDA into a brick.
What I found is that it is not needed. Since the "Windows Mobile
Device Centre" driver has been replaced, the
T-mobile Official WM5 ROM
works great and updates it to 2.26
without a problem.
I at random selected a Win 6.5 rom update from
MSD Wizard WM6.5 23085.rar
which only provides a nk.nbf
file and put it in the file where I expanded the VISTA_RUU.zip.
I ran the Vista_ROMUpdateUtility.exe
and the new Win rom
updated without a flaw.
I reloaded a copy of Spb Mobil Shell 3.1 without incident. It is an
GUI shell of tools and skins for the PDA. I then downloaded the 3.5
Spb update and again with out problems.
I’m truly blown away at what I can do now so simply with the new
GUI interface and the capabilities of Win 6.5 and can’t THANK YOU
enough for all your efforts to keep the user support alive. It’s like I
have a new phone with some modern capabilities on a six year
I couldn’t have done it without the knowledge and experience of
those who have gone before me. I hope these notes will help others
to make the leap.
