HP ipaq h6340 Some weeks ago I have bought on eBay this (great, IMHO) PDA.
It’s a compact PDA, with a relatively slow processor (168 MHz) that grant a great lifetime battery.
It’s and extremely wired device: it support
– Wireless a/b
– Bluetooth
– GSM/GPRS (quad band)
– Infrared
This PDA is in English language with ROM version 1.00.06 ENG. Also the boot screen say 1.00.06 ENG (with the final ENG release). After using this PDA for some days to evaluate his capability, the next target is upgrade the firmware and the ROM. This step is needed to improve and fix a ton of features. The version 1.00.06 is the first release, with many bugs.

Upgrading the ROM you upgrade also the operative system (Windows Mobile 2003). You can improve GSM/GPRS reception, Wireless reception, battery life, etc… (search all changelog on HP website, under the iPAQ h6300 family).

To upgrade firmware you need a box running Windows and ActiveSync. Download the correct ROM, like SP30391.exe (the 1.11 English version) and run this exe with the iPAQ connected to this computer.

Playing with this procedure i have discovered a strange problem: my iPAQ was branded TDC (a Danish mobile carrier) with a proprietary ROM. So I’m unable to upgrade with the official HP ROM files.
This is the error message before the beginning of the upgrade procedure:

Incorrect device SKU! update cannot continue.

I suppose that the problem is the ENG word into release string.

Damn! ๐Ÿ™

Browsing some Danish forum (and I don’t understand Danish! ๐Ÿ™‚ ) I have found this link:
go to www.tdcmobil.dk -> select erhverv -> select Produkter & Services -> select opdatering af HP ipaq h 6340

From this page/popup you can download the ROM 1.00.36 that will update the iPAQ from 1.00.06 ENG to 1.00.36 ENG.

Not too bad, but the last release is 1.11 and the ENG string is still here. So, after some others hours of research and experiments I have found this cool page that explain how to upgrade an iPAQ ROM from a different language. My iPAQ is already in English, but this procedure will “force” the upgrade process, so I can re-flash the branded ROM with an original ROM from HP.

I have downloaded the hpRUUSP30391.exe, a modified hpRUU.exe that will replace the original one. I have unpacked the SP30391.exe, replaced the hpRUU.exe with the patched version and booted the iPAQ in bootloader mode (pressing the mail and contacts buttons at the same time and pushing the soft reset button, wait until the bottom right corner reads BL before connect the iPAQ to the PC).

Bingo! My iPAQ now run the ROM 1.11 (English version without the ENG word into the string) and it’s ready for any regular future update.

Please remember that this procedure worked for me but I don’t have any warranties that will do the same with you! Flashing any device can break the device itself and you can trash your iPAQ. I’m not responsible for any damage to your PDA.

Thanks to ferdy for some assistance ๐Ÿ™‚

you can try to install a web browser like firefox
and see if firefox let you to download the file.

Otherwise you can try to get wget for windows here
then from a dos prompt you can execute wget with the url to download.

Don’t worry, if I have time to help you, you are welcome ๐Ÿ™‚

Paolo · November 30, 2006 at 01:25

Well, if the problem persist also after a rom update, I suppose that might be a hardware problem. So it may be impossible repair with some software…

I’m sorry.

Paul · December 20, 2006 at 17:48

I have a problem with the HP 6340, when the telephone rings the caller can hear me but I cannot hear the caller. Is there any way to fix this ? Could you please contact me directly to pmavros@chem.auth.gr ? Many thanks in advance.

Paolo · December 21, 2006 at 00:54

Paul, if you have checked the settings on the microphone volume, and is all right, I suppose that your is a hardware problem, so no one here can help you. Only a repair service can help you…

Ciao..Pensi sia possibile trasformare il mio h6315 inglese in un h6340 italiano?? Io non ci sono riuscito. scusa,avevo sbagliato mail.

Paolo · April 12, 2007 at 09:26

In teoria dovrebbe essere possibile, in quanto tutti i modelli della famiglia H63xx sono molto simili, ma non avendo provato di persona (non ho altri modelli su cui sperimentare) non saprei dirti molto…

Mi spiace.

Marco · June 13, 2007 at 10:53

Ciao, chiedevo un aiuto, come posso fare a fare il Bootloader mode! Le ho provate tutte ma non ci salto fuori!


Paolo · June 13, 2007 at 13:12

Beh Marco, io ho appena riprovato con il mio iPaq ad entrare in boot loader mode ed e’ stato decisamente semplice: ho appoggiato l’iPaq sul tavolo, ho premuto con indice e medio i pulsanti contatti ed email (quello tutto a sinistra e quello tutto a destra, per intenderci) e con la penna (sempre tenendo premuti i due pulsanti) ho premuto il “pulsante” di reset.
L’iPaq si e’ riavviato e sulla solita schermata bianca con il logo al centro, sopra la scritta nell’angolo in basso a destra dello schermo, e’ apparsa la sigla BL (che sta appunto per Boot Loader…)

Stai usando mica un’altro modello? perche’ se si, potrebbe cambiare la sequenza da fare…


coolstuff4real · October 5, 2007 at 15:56
