HX4700 Locked up

[Guest danmancs]

Hi, I'm hoping someone can help me.

My hx4700 is refusing to boot up. I installed Resco Explorere on it and it asked me to reboot it, so I did, and now it won't start.

It hangs on the boot screen and never gets any further. I have tried soft resets, hard resets and clean resets, but nothing. With a clean reset, it gets as far as "Clearing Data, Please Wait...", then never gets any further. I've taken the Battery out for extended periods and tried it all again... nothing

Has anyone experienced this and knows what to do??

I contacted HP support chat, and the best they could do was to update the rom, but as I pointed out to them, if I can't boot it, I can't create an activesync connection, so I can't update it.

Any help is greatly appreciated.

Cheers,

Dan

I just got done solving a similar problem in another thread. It seems like this type of thing is happening more and more these days. Really it's just one big problem caused by many different things. Anyway, here's my solution...

The first step is to get a copy of the rom image onto an SD card. Download the latest WM5 ROM update from HP and start the installation (it will fail but what needs to be done will be done) Using a hex editor (I recommend the Cygnus Free Hex Editor) you need to delete the first 2600 bytes of NBF that is included with the update. The file should be located in a folder with the same name as the update EXE in C:\iPAQ\. Then use the trial version of All Image (Link) to write the rom image to an sd card. The card should be 256MB or larger.

The next thing you need to do is to upload the rom image to the pda. Remove the battery from the pda and put the SD card into the slot. Put the battery back on and connect it to power but not USB. On the pda hold the power button, contacts button, and iTask button and shortly tap the reset button. It may or may not say "Press power to flash". A progress bar should appear and the percentage should slowly increase. When it's done it should say the checksum was ok or it was a failure. It doesn't matter which comes up it just means it's done. Then perform a hard reset and you're device should be ready to go with WM5!

Hope that helps!
