Ipaq h4150 failed rom upgrade (white Screen)

It should be possible to update the ROM to the english version.

You can download the update utility here:

The support site also contains installation instructions. Please be 100% sure that this is the correct update for your model before doing anything as an incorrect ROM flash can damage or permanently prevent your iPAQ from working.

Your HP IPAQ has a SDIO expansions slot...

which is a new technology.

so will have to use an SDIO card ...
this is a secure digital IO card.
hope this will solve the problem

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...'

You will need to ensure that the Wireless Security settings on your router are set to at least 802.11 b/g and not just 802.11g, as the h4150 is a 802.11b device.

There is also a ROM update to 1.10 and a WLAN driver update to 2.0.53A available from HP as well for this device. http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareIndex.jsp?lang=en&cc=us&prodNameId=349044&prodTypeId=215348&prodSeriesId=349042&swLang=8&taskId=135&swEnvOID=1087

What is your brand ?

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. :)

you need windows activesync

thanks for the post. the first thing is to install the ipac software and try see if the syetm can sysnc. when properly configured there should be an ipac icon in my computer, open this folderand other sub folders will be visible,if you have an SD card media in this device it will be visibleas well. try copy the music of your choice from the system into the music folder or your sd card depending on your pref.

You may be in need for a ROM update/reinstall. It is pretty easy to do that. You can either go at HP's web site and download a ROM update for your specific model. Make shure you select your operating sistem rigt. Or you can browse the internet for a specific ROM update for your model. I recomand the HP site, and if you have problems regarding the ROM update process, or the ROM and OS version you need, please reply here and I'll guide you throught. Good luck.
