Re: Ipaq H4150

Have you used a Vista PC as the host machine? ROM updates can only be done from a Win XP or 2000.

Hook the iPaq to an Win XP or 2k PC, install active sync first, and then get the ROM update again. Run the Rom Update Utility and it will recognise the iPaq and will update it correctly. :)

Hi I treid to do a ROM update on my HP iPAQ 4150. The update stopped and the screen now shows 1.05H and 1.02 and only the HP logo. Does not go anyfurther. Furthermore the iPAQ is not recognized by...

I ran into the same issue with a H4150. Pull the main battery and let it sit without the battery for a while; a few seconds is not long enough. I let it sit for about two minutes and that was long enough on each of the four times I needed to recover from a failed ROM upgrade last night. This reset the H4150 and it then initialized like it was just out of the box; all data and settings were reset to original. Some troubleshooting procedures indicate you should not use a USB hub for this process. That did not work for me-the ROM upgrade still breaks the connection just after getting started. But at least pulling the battery got the iPAQ back to a useable condition. My next test will be to try it from an old PC with Windows 98 and USB 1.1 or 1.0. Maybe the brief disconnection is normal and a fast PC with a modern OS may not be as forgiving to brief upsets. Just as the ROM update really begins (after all the handshaking), the iPAQ briefly drops the connection and that's when the update fails, it just takes a little longer for the software to say 'hey-I've lost communication with the iPAQ...'

Not a problem it happens just go to download the bios driver and use it on windows xp it will not work with anyother windows and run it with your ipaq connected to the pc. This will reinstall the complete bios software and bring it back to factory.

Hx4700 wont work after failed update on ROM v1.10

Try hard reset: pressing and holding the calendar and iTask buttons and doing a soft reset for 2 seconds.

Hard resetting a WM 5 HX 4700 is to press and hold the Contacts and Mail buttons and then doing a soft reset. The boot screen will popup with a message “To perform a clean reset, which will clear all data in memory, press the [Calendar] button”

If that fails, try upgrading to wm 6 or wm 6.1 then downgrading afterwards.

I've upgraded from wm2003SE to wm6.1 alkor rc2.2 rom.

PDA stops during Bios upgrade

If you have tryed hard reseting it then

You need to get your hands to a working flash of your pdas operateing system, can be hard to find, I was lucky I found many for mine.

After you have the software and the tools needed, most likely the software will have instructions so it shouldnt be hard to do.

After a successfull reFlash of the operateing system everything should be fine.

If you where playing with the bios you need to flash a working version to it. If you cant do it youself I recommend takeing it to a professional, the bios chip can be hard to reprogram.
