Since i’m very free today (no overtime, no more movies to watch for today, no syg this week 
) so I’ve decided to get my iPAQ HX2750 upgraded to Windows Mobile 6.1 and it took me 30minutes to get things done. Here’s how it works :p
1) Download the WM6 ROM from here (http://rapidshare.com/files/110252765/iPAQ_hx2000_6.01.02_WM6.1.rar.html).
2) Uncompress the downloaded file & put it into this directory (C:\wm6\). I’m using wm6 as it’s folder name just to make sure there are no SPACES in the directory path.
3) Plug your iPAQ to cradle @ USBsync cable.
4) Get the device to Pre-BootLoader state by pressing iTask + Contacts + Reset button.
5) Then just run the C:\wm6\hpRUU.exe
6) Now you can get yourself a cup of Tongkat Ali and wait for it to flash your iPAQ 
7) After the flashing process has completed, let it reset on its own and you’ll get your precious iPAQ HX2000 series running on Windows Mobile 6.1 ! Yeay!
GOOD LUCK
PS : Now my iPAQ is running faster on WM6 than my previous WM5 :p

Hey thanks for posting this. Trying to follow your instructions but every time I put the device in pre boot loader mode it loses connection with the pc and HP RUU programme says error with activesync lost connection. How can I do this please. Thank you. Adam
Now my device says “digital sign mismatch” and the pc window says “wrong dll for device”. I don’t understand! My device is genuine Ipaq 2790, bought in KL so what is the problem? Please help. TQ.
Hi Adam, since you’ve came to the second part of the installation, i’m assuming you dont have anymore issues with your activesync anymore. I too encountered the “digital sign mismatch” error. So what i did is I transferred all the files into this folder “c:\wm6″ so that my path has no empty spaces. Then only the digital sign mismatch problem resolved.
Wrong Path : “C:\iPAQ hx2000 6.01.02 WM6.1″
Right Path : “C:\wm6″
Just make sure there are no empty spaces for your installation folder.
Hi,
so how do you know this is a good Wm6 upgrade, with no bugs?
Does it include all the microsoft software and connectivity tools, etc?
thank you
bruce
So far my PPC didn’t face any problems with the WM6 upgrade assuming it’s good and bugs-free. It’s actually a whole package of complete WM6 including mobile version of MS Office & also ActiveSync plus the WiFi & Bluetooth (since my PPC only have those connection available).
I’ve tried to follow your directions, but I continue to get the missmatch error. I have a 2795. I’ve removed the passwork
bruce
Have u make sure your directory’s like the example?
C:\wm6\hpRUU.exe
*and other files are also in the same directory as above
Yes I have. I’ve even tried shorening it to c:\6\hpRUU.exe
I’ve been thinking about what could be going wrong. The preboemot loader state may be the problem. When do this it goes to the rebooting screen, but does nothing. I have to do a soft reset to get it to reconnect. Am I doing something wrong here? Should I try doing a hard reset or reinstalling the wm5 software?
thank for your time.
Yo man!
I folowed your instructions (including coffie tips) and everything runs OK. IPAQ 2790 is now working perfectly, I’m sure it’s faster now then before with WM5.
Thank you!!!!!!!!!
did ur device have shown the Pre-BootLoader msg during the reboot?
hey man! i have a problem with the installation.. when i put my ipaq hx2415 in Pre-BL my PC don’t recongnize it, and i can’t run the upgrade… can U help me! :0S
Thanks NeoTech
Hi NeoTech and Adam,
I cant get my device to be correctly connected while starting in pre-boot… Is there any trick ?
Thanks
Hi, I heard a lot of positive opinions about another ROM – 5.07.04 – being said that WM6.1 ROMs are a little bit unstable and generally less recommended that WM6 ROMs (as of May 08). Do you have any experience in this? Can you tell that this new ROM is better (as in faster & more stable) than the older one I found?
Hi there. I have HP iPAQ 6320 Palm OS. it has WM2003. I want to upgrade it to WM6. Can I do it with my Bluetooth, WiFi and phone still functioning? This would be really nice if I could. I would highly appreciate your help.
Hi I have a issue with this romon my hx2110 upgrade is ok but ppc don’t want boot after .I have the HP screen with a blue bar growing, whit “6.01.02.PV” write, but when the bar is full nothing happens…. somebody can help me please??
And I can’t flash back to Wm2003… Please need help!!
hey all, I figured out the problem with the pre-boot not communicating. Just hit the calendar button on the pre-boot screen so that it says “USB” in the bottom left corner of the screen. Hope this helps all you guys!
mine is same as saq__d__aus……. Pls help…
Managed the flash well. Only problem on my hp 2790 was that contacts is non-functional. Anyone else experience problem? any fixes found?
Grab Tommy_Adsl’s link from here:

It is a WM6.1 Rom that worked for me. Contacts too. Only problem I am experiencing is the charging bug, where the battery status does not update. Seems to happen with the Rom from this page also.
All of this works great however you cannot use Windows Vista’s Sync program you MUST use the Windows XP’s Active Sync. I tried a number of times and had an old XP box laying around and that is what it worked on.
can i upgrade my iPAQ hw6965 to WM6?
Hmm, how about downgrade (if upgrade is fail).
terimakasih sudah share.

help please!!
Hello. Thanks for the upgrade. Worked flawlessly. Ipaq 2750 running wm2003se. Synced it ran the update from the folder as sugested. All buttons work. Thanks again. Now I can use more up to date apps.
Hx2790C
Dos anyone know of a rom that will work on the 2790C. I can’t find any information on the C model. Thanks
Has anyone found a way to get this to work through Vista. I don’t have access to an XP machine to do this on but would really love the improvements.
Thx,
I didn’t have any problems doing the update… The only thing that I’d like to notice is that the HP program doesn’t work in Windows Vista… I guess because the ActiveSync. I tried in Win XP at the company and works fine.
The programs are faster and better!
Thank you to NEOTECH!!!!!

Rapid share doesn’t work for me, do you have another download link for the “Upgrade iPAQ Hx2000 series to WM6″?

Question: what drivers are used in vista?
THere are two alt drivers that stand alone and there are a slew of them now. SHould I change the drivers for my HP Sync device?

Error Message 503 ACtive Sync Error (I HAVE VISTA)
