Default iPAQ hx4700 ROM upgrade - without reinstalling any apps after

Unfotunately, ROM upgrades also mean the need for reinstalling all your apps and applying all your settings, which, in many cases, means days (!) of (futile, because it's not needed if a proper hack is used) work. This is why I have been investigating a lot of ROM upgrades to greatly ease this task by just enabling restoration of previous, pre-ROM-upgrade backups and just applying a registry / Windows CE database update. Please read http://www.firstloox.org//forums/showthread.php?t=3585 and the related threads (I've linked quite a few of other threads from my article - you may want to read them all to get a picture of how this all works) on this - I, as a programmer & hacker, have elaborated in there on why this is sufficient and why this is safe. (BTW, hundreds or even thousands of people are using my Pocket Loox upgrade hacks. Noone has run into any problems as yet.)

1, backup the contents of your PDA with the built-in iPAQ Backup. Make sure you back up to a memory card and not to the iPAQ File Store - the latter gets erased during the ROM upgrade!

2, save the contents of your iPAQ File Store (saving right the root directory and all subdirectories) in the way described at, say, http://pocketpcmag.com/forum/topic.asp?TOPIC_ID=15577

3, upgrade the ROM

4, restore the contents of the iPAQ File Store (see bullet 2)

5, restore the iPAQ Backup backup (see bullet 1). Ignore the warning.

6, download the ZIP file at http://menneisyys.freeweb.hu/hx4700R...ImportVer2.zip . Decompress it.

7a, if you prefer Resco's apps, download and install Resco File Explorer, followed by Resco Registry Editor, from http://www.resco.net/pocketpc/explorer/default.asp . Upload resco.reg (ignore tre.reg!) on your PDA (for example, in the root directory).

7b, if you prefer free apps (even if Resco's trial version will work OK), get Tascal Registry Editor from http://pocketpcfreewares.com/en/index.php?soft=92 and install it. Upload tre.reg (ignore resco.reg!) in the root of your PDA.

8. start Pocket File Explorer on your PDA and go to the .reg file you've just put there. Click it.

9, if everything is OK, you'll see a message that the registry file has been successfully imported.

Please note (the usual disclaimer stuff): much as I've spent several hours of my life on this hack and I know pretty much about how the Registry and Windows CE/Windows Mobile works, there may still be errors in it (synchonizing registries, Windows CE databases etc. isn't very easy.) They, however, highly unlikely cause any serious problems. Several European hx4700 owners have been testing my hack for some hours and none of them reported any problems with it so far. I'm in no way liable to any freezes, crashes etc. you'll encounter.

Also, please report if you run into something special or strange!

The only strange thing we've run into after restoring a previous backup was that Snails 2 and WMP10 used Landscape in the opposite direction. I haven't had the time, as yet, to check out why this happened.

Note that there is no difference in the Windows CE databases. (I've checked.) This is why no database-related updates are needed.

For hackers and tech geeks, it's really worth checking out keys like HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DirectX (DirectX before WM5? Great!) and HKEY_LOCAL_MACHINE\SOFTWARE\Widcomm\Plugin\HandsFree: at last, a working handsfree solution, with the PDA being the handsfree ? Cool! See http://discussion.brighthand.com/sho...hreadid=115458 on this problem if interested.

Default hx4700 Rom UG / Working handsfree solution with the PDA being the handsfree?

Your solution has worked well! I still may go back to ver 1.00 ROM since my Mugen 4500mah battery is not fuly seen under 1.10.08.

To the point...thanks! It is absurd to have to "reinstall-it-all" like HP says you do. I actually noticed that after I went from 1.00 to 1.10.08, then loading all my apps--THEN doing your procedure twice:

once with no registry update
then
a second time(from a backup) with registry update.

The reg update wiped out a few registrations--like for my Resco 5.13 and a few others but I saw no other problems that I could detect.

So contrary to whatever HP/others besides yousay, you CAN overlay a 1.00 final backup on the 1.10 ROM with the registry update--or even without?

Any major concerns about NOT doing the registry update? (ignoring steps 6 7 and 8?) if you don't respond here, assuming you have the time, you can respond to my direct email address at the bottom of this post, just remove the second @ sign to protect me from spambots

Secondly,

DirectX and Handsfree on the pocketpc registry? you mentioned

"at last, a working handsfree solution, with the PDA being the handsfree ?" but I don;t seethe solution, or can I figure it out from that reference..."See http://discussion.brighthand.com/sh...threadid=115458 on this problem if interested"

I have tried many ways to get this telephony handsfree-pda to work [like data does] as my "pda and phone nirvana" with my hx4700 and Verizon/Motorola V710 (phone is more the issue there)--especially since programs like Skype work so well with ip telephony, and the hx4700 has a speaker and microphone in just the right positions to make it usable naturally as a phone with a BT audio-gateway on a fully BT-capable phone. So in summary, pda-to-ppc Bluetooth two-way connects work for data, but not for voice telephony... what a shame. I would like to work on this project, and I'm learning all I can on it...

Great job... you motivated me to try some new backup solutions for my hx4700 and once again, what I'm told to not do by the big wigs at HP does indeed work, and work well.

Yes, if you upgrade the registry.

- there are no differences between the WinCE databases (checked)
- there are no differences between the RAM-based systems programs (for example, \Windows and \Windows\Startup)
- therefore, it's only at flash ROM (which isn't overwritten, unless you had the RAM-based HP sound fix installed when you made the backup) and the registry that they differ.

The registry is really different between the two ROM versions. Most of the new reg. keys are related to the new functionality (for example, DRM) or WMP10 (feel free to look in the registry file - it's human-readable and the regkey names speak for themselves). Furthermore, all version numbers of system programs are stored in the Registry - therefore, you'll see the old version numbers of the otherwise (in ROM) physically upgraded apps if you don't upgrade the Registry.

Therefore, it's highly recommended that you update the registry. A lot of new WMP10 functionality won't work or, at least, will have problems if you don't do it.

See as above. I also recommend the thread at http://discussion.brighthand.com/sho...hreadid=118359 on this stuff. That thread is more technical, but there're a lot of information there too.

Did you also test it with the new ROM, after applying my registry upgrade?

It's not guaraneteed to work - this is why I used the question mark in my question. I just hoped it would work because of the new reg. key.

As far as WMP10 functionality without and with my reg. upgrade is concerned, iPAQ HQ user Chemong has just posted some relevant info on it at http://www.ipaqhq.com/forums/showthread.php?p=85044 :


Thanks!

Thanks, after installing the ROM update and restoring my software with Sprite Premium, Windows Media Player 10 wouldn't work. I installed the hack you provided and WMP10 seems to work now.

Thanks"

Default Reg patch working well.... only two problems noted

Two problems with the reg patch seem to be:

1) Resco Explorer "unregistered" itself.... I'll reload that tonight...

2)Trying to downlload a podcast from dave's ipaq # 05192005 [at http://davesipaq.com/archive.php?c=22&type=n] resulted in an inability to save the 22mb file anywhere that I have verified has enough sapce beforehand--locations tried are to Main Memory, SD card, CF card nor ipaq filestore. The rest works well...

Ideas? -Jonathan

Several users have reported this; it may depend on something that the ROM upgrade modifies because I keep all its registry entries. Or, it has a bit too advanced copy protection mechanism

Dunno... did it save before the upgrade? Did you try alternative downloading methods?

I've elaborated on this a little more and am pretty sure that Resco also checks the ROM version number to combat cases where an already installed and registered copy is put on another device. That is, Resco must be re-registered upon restoration from under a previous ROM version.

Jonathan I am sorry you are having problems.. I will send up an email over to the folks at Resco and see what the scoop is.. I know they listen to the cast and see if they have run into the same problem
