vivi ROM Kitchen for iPAQ Hx4700
Mainly modified from Scoter Kitchen​
Introduction
I've made this iPAQ Hx4700 ROM Kitchen because I think someone can make it,but no one 've made it till now. So I made it myself and share.
And someone asks me for this after I publish my vivi ROM Kitchen for ASUS P525.
Though it is not the best and complex Kitchen with many features and I think not many users want this Kitchen,but it's good to share.
The main aim of this ROM Kitchen is easy using, so this ROM Kitchen is only one click and follow the screen.
You will have a new ROM for iPAQ Hx4700 at ease.
Aims
1.For easy modifying private ROM.
2.For helping new user to easy start cooking ROM.
3.For sharing OEM Packages.
4.For someone makes it better.
Let's see
Before using it just let us understand in the same way as follows.

2.I don't want any credits for this Kitchen , only named it vivi Kitchen since it is my attempt and only want to give this community back the thing I can do.Credits should go to the names I stated in Thanks Part above.
3.I hope you will develop this Kitchen better and share.Or share your OEM Packages or knowledges.
4.All feedbacks are welcome.
Thanksss
Vivi,
THANK YOUUUUU!!! I'd been trying to modify your ASUS kitchen with no success. The 4700 community will truly appreciate this. I agree, kozhura's rom is great.
Regards.
Thanks so much vivi! I'm so happy!
Is it possible for me to use kozhura's latest WM5 ROM as the base rom? What should I do to make that into packages and modules? Also, is there any way to calculate how much free space is left in the ROM for adding OEM packages?
Thanks again!
Thanks. This is giong to be my first "cooking" experience. A nice new way of playing around and improving the hx4700 at the same time!!
Been doing some late night cooking... tastes great. Thanks vivi for bringing this out.
Thanks for the WM5 kitchen!

What should I modify to get a 8MB or 32 MB PagePool?
Thanks.

Don't downplay your part here!
I'd had a tinker with decompiling the ROM but never quite got it to work right so I too am very grateful of your assistance here.
I had a quick play last night and the largest file I saw was Powerpoint, my old favourite for the largest waste of space on previous ROMs so first to go to make space for the useful stuff!
And just how can you remove Powerpoint?

Well simply deleting the 2.59MB ppt.exe executable from the SYS\Office folder will get rid of it, but how do you get rid of all the traces (registry settings, links, extensions) that are tied to it in a clean and efficient manner. I know I can manually remove associated files and such, but what happens to settings in the .dsm file? I can manually edit the .rgu files, but how do you edit existing settings in the .dsm files without breaking something?
Can I remove the "HP Protect Tools" OEM folder (15836286-5263-4a11-8b33-5087ced93124) safely, or is it required by other applications in the ROM?

And then, deleting ppt.exe will cause no harm, even if you leave there all the debris? 2.6MB gives quite a lot of room for small apps!

I delete the ppt.exe as suggested, but I go through every file also to be honest and remove anything that refers to powerpoint, the link file, registry values for 'pps' or 'ppt'.
Whilst doing this I remove other things I don't use (though to be fair this is from when I used the Universal which had a lot of extra crap in it) and tweak the registry value to those I want (though again I can't see that I need to change a lot here).
Easier and quicker is to do a search of all files for the contents of ppt and pps and delete from there.
Vivi many thanks to you,great work for users!
kozhura,
Appreciated your works so much.
You are genius and so kind.
Thanksssssssssss,

Hi,
I have looked a litlle in your kitchen and this is a very useful tooll, thanks !!
Here are my first questions :
1.
I have seen this folder in the OEM :
vivi\Enter Kitchen\OEM\b693f6e6-e6cd-4091-b8f3-40f2b988b169
It seems to regroup every phone manager. As I never used it and I don't inted to use it, can I delet this 2.38 Mo folder without any risk ?
2.
Does someone have information about changing keyboard or adding a new one ?
(I need an azerty one)
3. (harder)
Does someone have information about changing language of the rom ???
4.
How much space do we realy have left to add OEM packages ? (I have searched but I didn't find an information about it)
albertorrent, I can't help you specifically but when I play with ROMs I tend to keep the last working version and then tweak.
If it works fine, that is the new last saved version, otherwise I go back to the previous and tweak differently.
thanks, I think I 'm gonna do a lot of try.
I have an other question, (may be the last for today ;-))
How to add a font in the font folder in windows ?
Hi,
I would like to share the kitchen that I use to build my personal ROM. It's SYS and XIP were ported from the stock Diamond 1.93.456.2 WWE ROM that Tom made available and the kitchen is Bepe's kitchen.
Here it is (Build 19965.1.2.3):
http://rapidshare.com/files/130210385/Artemis_Diamondish_6.1_Build_19965.1.2.3.zip
UPDATE1: I have made a few changes in the OEM folder, I have added Advanced Config, added a patched htc home for the weather and made some changes to the registry. The changed files are in the attached zip.
Pre-Built ROM (NBH) can be downloaded from here:

(Usual rules for cooked roms, i.e. USPL etc.. - http://forum.xda-developers.com/showthread.php?t=331845)
UPDATE2: I have uppdated the XIP and SYS to use build 20273.1.3.3 and use .NET CF 3.5 as suggested, thanks xvx45

Here are some screen shots (of build 19965, mainly the same as build 20273 and 20721 but version numbers changed):
Nice work bro, nice to see new "faces" on Artemis forum.
Cheers.
Thanks, been here a while, just learning as I go. I thought it was a bit quiet on the new ROM front.
Thank you very much for you sharing!
Maybe this was the push i needed to start also cooking.
Who knows...
Cheers
Thanks for share man!
Do you have some screenshots of this ROM?
INFO
Hi,
Just extracted, saw all the separate files, did i miss the full .nb rom image or is this post to cook yourself with the htc romtool?
I know there are a look of cooking-guides, but can anyone explain simple which files tot select from the extraction when running the htc rom tool you have to fill in :
G3 IPL
G4 IPL
SPL
Splash
Radio Ext.Rom
OS
Can i add also .cab files for example somewhere to add to this rom?
Would like to cook first rom.
Thanks,
Innovator
Hi, just run the batch file "BuildNB.bat" and that will generate the .nb and .nbh files, they were removed to reduce the size of the archive.
You may also need to install the VC8 Runtime first, that can be found in the archive:
"tools\vcredist_x86.exe"
There is a tool from Ervius (I think that it is called "packages creator") that will convert cabs to OEMs suitable for cooking with.
Thank you mate, I'll try to make it compatible with Orange France SPV M650 AGPS
Maybe my starting element to come with Artemis community more often (actually my phone but Icook on my old Prophet at this time).
Good job
Hey guys,
This seems promising. I've just installed Tom's latest but have been troubled by bugs (it happens) since he's no longer responding to queries I decided I needed to learn to cook one myself (should be fairly straightforward).
Perhaps we should pool experience & resources and work together, I mean if you look at the activity in the Kaiser forum, you'd be forgiven for feeling a bit left out.
One person could design gfx the other sounds etc. Otherwise I might swap my Artemis for a Kaiser (yes I've been begged!!)
Forgive me if this seems like a pipe dream...

I agree, it would be nice to have an "open" ROM that the community contributes to, I hope that this would keep the Artemis platform alive for future releases of Windows Mobile.
P3350
Hi all... i am very new to cooking and still thinking of getting my feet wet... have a couple of questions...
1. I have a P3350 (Artemis with out GPS) and when i install all these roms they are sluggish when compared to P3300s. My friend has a P3300 and the same ROM is fater ... I tested it immediately after flashing by opening the windows folder and other apps... should i be doing any thing different to get my device up to speed?
2. The ROM on the rapid share (http://rapidshare.com/files/13046620....3_NBH_ROM.zip) is this a directly installable ROM?
3. What should i be doing with the 'changed files'.
Sorry if i am sounding noob...

I don't know of any, but I am looking into a similar issue that I see with my orbit, I think that I am going to look at the XIP region of the ROM to see if there is something device specific there, sorry for not being much help.

Yes, this contains everything but assumes that your device is already running the SPL and only contains the OS portion and not the radio. Look at the link in the first post for help on flashing cooked roms.

These files in the zip should replace the existing ones in the kitchen on rapidsahre.

Freshup Roms...
Good try for this new rom, but i find the home-skin not stylish enough (dated too soon).
Why not create a rom with Greatball's today screen, see http://forum.xda-developers.com/showthread.php?t=402021
This is the most stylish skin (with SPBMobile 2.1) i have ever seen (last one with analog clock).
Together with Greatball's Samurai Diamond Weather + Night
http://forum.xda-developers.com/showthread.php?t=402124
Would be the most fresh looking rom ever
In combination with latest msn, SPB-backup,PPCBackupcontacts,...
Who can do this & freshup our Artemis for a long time ?
Thanks,
Cheers!

When an Italian version?
I have no plans to produce any other languages, but the source to the kitchen is all there for someone to translate to suit thier needs.
Ok, I've tested and make my first Artemis ROM (for test use for the moment).
I've been implemented Orange AGPS drivers but no luck no automatic connexion at the moment when GPS is activated so, I'll make more try. So I've removed some components (Adobe flash & reader, Diamond Keyboard and some little thing) that I don't want and this ROM is stable and fast...very fast coocked with NETCF3.5 Now I'll translate it to French if I've time to that more than my future release
Just one thing mpattman : why to release this kitchen with NETCF 2.0 and not directly 3.5 ?
And the last Word : Thank you mpattman !!!
I can not down your ROM and MYkitchen,please get it to FTP,thank you.
Thanks a ton...
Thanks MPattMan...
I am downloading the kitchen, and will try understanding stuff... will post if i have any doubts... do u have any guide on how to do stuff like adding the programs that i want ? ... i will be more than willing to help, test and learn.
Hey there
I'd like to cook an own windows mobile-rom for Artemis with Manila 2D. I found HyperCore to cook the rom. With HyperCore, you can edit an existing rom or a "clean one".
Where do you get the unbrandet, new versions of wm 6.1 for cooking from?
thank you!
you dont necessarily need a ROM as a base
if you want a specific build then google for that build and find XIP and SYS
and put that in your kitchen
and if you are new you may like to start with "artemis diamondish kitchen"
its very simple and easy to use
thank you!
with "artemis diamondish kitchen", I can include also the manila files?
yes you can
get OEM package for the apps you want and put them in OEM folder of kitchen
and it will work
Hi here i release an OLD style kitchen based on Bepes tools
I have taken bepe's kitchen and created some batch files to make it a one click extract and one click build and flash
I was so used to the old style kitchens and when they stoped working (failing at xip extract) i was looking for something that worked that i could use easly.
I found bepes kitchen, and it was nearly the same so i ported the batch files from diamond kitchen 0.4 to make this.
this kitchen uses the new style packages but has the look and feel of the diamond kitchen 0.4
I am still looking for the package creater that makes these NEW style packages but can't seem to find it now so if anyone has it please drop me a link so i can include it in the kitchen tools
download link ---->
http://rapidshare.com/files/217781904/Kitchen.rar
Instructions
1 place you RUU_Signed.nbh in the baserom folder
2 click on !Begin
3 Dont touch anything until extraction is finished (approx 5-10minutes)
4 Modify your packages
5 click on !Cook
6 wait until the htc rom tool loads
7 select diamond in device, os.new.nb as the source OS and save as kitchen/RUU_Signed.nbh
8 close htc rom tool and Custom RUU flash tool will load
9 flash and enjoy

will this kitchen group the OEM and SYS files properly. im having difficulty in using the new format or everything's in SYS\MSXIPKernel folder.
Is the Rom dump protected after cooking?

not had time yet to try and test if i can rebuild a cooked rom, will have a go tonight and post my findings.
This is Bepe's Kitchen automated by batch files so he is the best person to talk to about protection
sorry to be a little blunt but i am a noob when it comes to cooking that why i found something that worked for me and made it a little easyer to use,
Protected Rom? Almost Rom when rebuilding, it will delete all dsm file, so you can't use package tool.
ok i have now tried the flashing, and the cooked roms won't pass the splash screen page, not getting the device info in bottom right corner.
anybody there who uses bepe's kitchen mind having a look for me.
also i can't open a re-cooked rom

I had the same problem and it was a XIP "mess-up". however I can't help you more than this.
try asking here: http://forum.xda-developers.com/showpost.php?p=3575850&postcount=131
i simply do NOT understand why build a tool that deletes stuffs that are important for cooking. isnt rom cooking supposed to be an open project for ALL? i mean some chef have the donate button in their sigs. but their rom's locked. it isnt fair to those (like myself) trying to learn how to cook a rom. i mean, i try to compare official roms and custom roms insides. what are the difference. it's by comparing that people learn to differenciate. and i would say BAHHH to missing rgu and dsm files!!
My thoughts exactly... Alas...
it is ironic, that NONE of the chefs who lock roms/doesn't supply kitchen/ask for donation wrote the code themselves. In short - everybody operates on stolen/leaked or any other way obtained code.
Ok, there are authors who created tools. And those guys have full right (and reason) to ask for donations fro that - TOOLS.
Otherwise - it's just funny. it's like stealing a car, and then asking police to protect it....
no panic.
at normaly old style kitchens never delete dsm'S.
and if you delete manualy dsm'S, you get all files in folder.
i think, with protect rom it means, no recookable roms.
it stops at point 1 or in the first step by using BEGIN! with a message like
"rom is smaller/bigger than/at starts" or so. excuise me, i've forgot the exactly words.
for checking of recookable rom i checked it with "htcRIE_0.5.0.12.exe".
it shows you all files with oem/sys - folders. but the oem can be empty. you find the oem-files than in sys-folder.
these points are my thinks that i see/learned by beginning flashing and cooking until now. other people can see/learn other thinks so dont dismiss me, if you are not my oppinien - but you can dismiss my english
Htc rom tool
Is it possible to use this for the Fuze?
EDIT: I found HTC tools with support for more phones on this thread a couple posts down
I thought about doing another rom release, but I figured it would be just as well to release the kitchen and let you all make your own!
This is based on crc's v13.5 big storage, in ervius visual kitchen 1.8.1.
It should have everything you need to create your own rom. The dump is a cross between crc's naked and normal, but there are a lot of extra packages. It also has things like button 5 fix built in, and if you build with alt tab, it will automatically assign itself to button 5, and voice dial will assign itself to button 5 (press and hold).
If you build with glossy black bars, preconfig.txt will be used from the glossy black bars ext folder. If you don't cook in ftouchflo, make sure to remove the entries for it from preconfig (either in oem, or in glossy black bars).
Thank utaker for the batch in the release folder for setting up splash screens.
crc, ervius, bepe, anryl, and others did all the hard work, so if you want to donate, give to one of them, I just packaged it all here.
Happy cooking!

If you can find a rom to download, you can attempt to dump it using this kitchen.
Hey boog thanks a lot!!! do you think that there is a way to merge 6.1 and 6.5 in the same kitchen?
I mean if the kitchen is multibuild... multi lang, multidevice... why not to be multi core??? but i guess its not due to the change of the kernel but... maybe switching betwen the builds and OEMXIPKERNEL...
Thnaks again for the kitchen i will take a look at this.

I don't see why it couldn't be multi core! Or build 6.1 with a 6.5 xip. I just ran a test, but I don't have time to flash it (yet), I need my phone for work today.
6.1 built just fine with a 23017 xip from utaker's dv5 kitchen, as long as you left the real 6.5 aku unchecked (it will error, I believe utaker has the real 6.5 nk.exe in there). I renamed my original rom folder to ROM_61, then just dropped the ROM folder from utaker's kitchen in. That way it has all the files to make it happy in 6.1 or 6.5, now I just need to try loading the 6.5 pieces in.
It appears the rom will not boot using a 6.5 xip.
Looking at the differences in the rom folders, the os.nb.payload files are different size, and there are different files. I'm still not totally sure what they all do.
I may have to experiment to see if there is a happy combination.
