i am amazed by how quickly things turn around in here, not many weeks ago we were looking forward to XDA-Developers 1.2, now look where we are.
Because i'm such a cheap-skate i don't have internet access at home, but i do at work however for some paltry security reason 'ftp' is blocked. is there any way i could get 4.00.10 without radio.exe via http
many thanks

@jerome
I've installed it on my O2 XDA, I think it is a little more stable with a few less bugs. But if you install it there is TMobile software on it. You can remove it easilly, but you have to know what you do, which means removing the apps from the Startup folder and from the Today settings.
@david beckham
Well with which FTP program are you downloading? You can do it even with a web browser, it is pretty simple. Since there are now already 5 users downloading (which is the maximum) it is pretty clear you should download it without problems. Does it give an error?

I'm uploading the 3 files to my homepage now which is much quicker than my FTP. When it is there (about 45 min.) I will post it here.
Sorry the uploading to my homepage isn't quicker, but blame it on the guys who are downloading from my FTP which steal 45 KBps! :lol:

@Aurora13
Is your XDA Asian version ? Did you find any particular problem upgrading it to WM2003 T-Mobile version ?
Did you upgrade also the radio version ? My XDA comes from Asia and I'd like to wait for the radio upgrad that will be available this August...
Can you be more specific on how to remove T-Mobile software ? What do we have to do ?
Thank you !

As you can see I'm from The Netherlands so your first question should already be answered. But you can update your Asian XDA but without the radio update!
Your second question:
What to remove:
- Disable the TMobile Today plugin in Settings - Today
- Remove the TMobile shortcut from the Windows\Startup folder
- Remove Program Files\AIM if you don't use it and wants to save RAM space
- Remove Program Files\TMobile if you don't use it and wants to save RAM space
Reset the device and the TMobile stuff is all gone!

Sorry I can't host the files on my homepage. I've got to less space and my monthly bandwith can't allow it. So you guys are stuck with my FTP until someone else host it.

Aurora13
maybe I am new to this ftp thing, i just type this when i am in the ftp prompt
ftp>get 4.00.10 - exe-without-radio-update.zip
i still cant get the file, can you show me how should i get it?? I am using the ftp from the MS DOS prompt...

get "4.00.10 - exe-without-radio-update.zip"
should do the trick since DOS cannot use spaces without the "" around it
Good luck!

Hi!
When I click on your FTP Server I get the message:
403 Forbidden - The server denies the specified Uniform Resource Locator (URL). Contact the server administrator. (12202)
Internet Security and Acceleration Server
Any Idea?

Your solution:
Don't click on it!
Open it with a FTP program, or replace http://ftp.alain-net.net with ftp://ftp.alain-net.net
it is FTP and not a web site

Is This Safe?
Hey, Im Currently Running The Kitchen Rom 4.00.05 with Radio Version A.20.10 :S Is it safe to install the new tmobile rom 4.00.10 exe with radio update or ?? Any help would be great
Thanks, Allen
My Device:
Tmobile Pocket PC Phone Edition USA
Microsoft Pocket PC Version 4.20.1081 (Build 13100)
Rom: Kitchen Rom 4.00.05 ENG (PPC2003)
ROM Date: 06/05/03
Radio Version: A.20.10

I updated my XDA from ROMkitchen 4.00.05 to T-Mobile 4.00.10 .exe.
Somehow, I could not roll back to my previous ROMkitchen 4.00.05. When I execute ROMkitchen 4.00.05, in the adaptrom window I got an error message below:
“error: GetConnectionType – An existing connection was forcibly closed by the remote host.
error getting connection”
My activesync is still on. I am using Radio Stack 4.21.00.
XDA Developer please help ………….. or can anyone help me please……..

Heres the deal....
All i did was do the regular upgrade to 4.00.10 and got to 13% on Radio Stack Upgrade when it errored so i took it out did a few Soft Reset's no luck so i flashed the 4.00.10 Rom through the wallaby bootloader got it up waited patiently for CE to load... loaded after about 15 minutes at that time it was running terribly slow and when i got it up i had no service because i had no Radio Stack so i then loaded up this old radio stack well not so old but it was version 4.21 i then soft reset the device started the 4.00.10 install it went through the Radio Stack then the Rom update with absolutley NO errors or conflicts so everything is working great..
Ill keep you posted on any error's i find or conflicts with stuff so far nothing wrong !
Heres something to keep in mind DONT Upgrade To Tmobile Rom 4.00.10 With the radio stack version A.20.10 Or you will be doing what i had to do!
i want to say thanks to all the great people out there posting
Thanks, Allen

Thanks to Aurora it was easy as pie to flash the w/o radio stack tmo pre-release 2003 -- and I did it over 4.00.05!!
I like this rom much better too -- interface, response, stabilty all are much better than 4.00.05. However, I've only been working with it a few hours now, and that could change ... but I don't expect it to.

Asian XDA WM2003 Upgrade

Hi All
I am new to this forum and wanted to upgrade my Asian XDA to WM2003. I try to download the rom in Yorch.net but it doesnt seem to work at all. However i did find this T-mobile ROM Windows Mobile 2003
upgrade 4.00.21. Does this version work for Singapore Singtel Network? Or am i missing something here? I have read most of the forum here and is still quite confused. Can anyone here give a step by step guide on how to upgrade to WM2003 (which version) for ASIAN (especially Singapore) XDA? Pls share your experience.

hi rchtan
If you have not done so yet get the latest official upgrade for yr region and flash the radio this will give you "always on connection" and better stability.
Record all yr network settings as you will need to enter again after.
For WM2k3 Just get the 4.00.05 rom forget the higher numbers as its just the telco adjusting for their particular network and likely to cause more instability if you are not on Tmobile.
Get the installer EXE version and just click on it to install from yr desk top.
Make sure you are connected to activesync and switch off yr radio in case of incoming calls. You can add the extra progs avoiding the ppc2002 marked, forget the imov messanger(Jeff's never worked) you can get a working version fm their web site.
Hope this helps.

Hi alqwerty
Thanks for your reply. Another question which might seem stupid. How do we cook a ROM? I went to this link http://kitchen.romanweb.com/kitchen/index.php and if i left the "Add software and modify ROM" as click, there a big red warning sign "OVERLOAD"??!! Is it okay if i just download the base rom?

Hi rchtan
Start with clicking on 4.00.05 ENG ppc2003.
Then move from top to bottom clicking on what progs you need and unclicking those that you dont want(especially unclick all the ppc2002 marked ones). until the overload sign goes away. Then click on
installer EXE then click on build rom now. When its
cooked download the rom. Good luck

Upgrade my XDA (1) to New 2003 Software

Somebody plz help. Got a XDA 1 (A Version), and have Rom Version 3.17.03 ENG, and Radio Version 4.21.00. I am on the Vodafone (UK) Network and want to upgrade phone to new 2003 software. Is it capable of being done yet, and if so, what files do i need (or a link plz). Many Many thanx to all those who reply. Regards, Ronnie[/b]

www.yorch.net and please scan around the forum before attemting anything that may kill your pda.

thanx for the reply, i have been to that site but not sure which files to use/download. Any info appreiated, thanx, Ronnie

1. Go to the kitchen option on the left side menu. Select the base for your new cooked ROM ... ex: 4.00.05, or 4.00.16 ... etc
2. You should see the top screen gauge in red. That means you have to check and uncheck some of the s/w contents untill it's green.
3. Select the EXE method and wait till it's "cooked" then down load the ROM file. Connect your XDA to your PC using the cradle and run the EXE and follow the instructions.
4. IMPORTANT: better to have a backup on SD card befor starting just in case.
Good luck ...

Thanx, will that work ok with the A model?? :lol:

It worked for me. The difference between A and B is significant only for RSU upgrades not the ROM. However, official ROM upgrades do this check as well, but the kitchen doesn't .... clever developrs!!!

Is there any chance you could send me the 4.01.00 file, can't find it anywhere. I notice you have that update on yours, and radio vers 6.24.01, do you have that available too?? Will it be ok in the uk, or am i best just using the 4.00.05 one from the kitchen, and leaving my RSU with 4.21.00 vers.
Many thanx for all your help, Ronnie :?

I notice you have that update on yours, and radio vers 6.24.01, do you have that available too?? Will it be ok in the uk

One very important lesson, if you have a functioning RSU, do NOT mess up with it :lol:

Got it updated thanx, works very well, but cant get active sync to work now, downlaoded v 3.7.1 and still nothing. Any ideas?? Ronnie :x

what is your device info right now ?
what type of error you get with active sync and is it on the XDA or the PC ?
Hint: try another PC to see whether it's your XDA or the PC

Device Info is:-
Rom: 4.00.05 ENG
RUU: 4.21.00
Worked fine before updating Rom, not done anything different to pc, and now it just can't find the XDA...??
Not sure why.
Ronnie :?

Do these tests in order and check the result after each:
1. soft reset
2. reinstall active sync
3. another PC
4. hard reset

many thanx for teh advice, got it sorted now, had to re-install active-sync, now works a dream, and a lot faster too. Many many thanks to Biso007 for your help, this forum is COOL

It doesn't matter which ROM you have now. Just cook any 2003 ROM there and it will put you on WM2003 (unless your device is from T-Mobile, 4.00.05 is a best choice).
Good luck

Special Edition WM2003 Rom?

ok, i have installed the special edition rom for my xda1 and its a definate improvement over the original rom..
but i noticed that the window mobile 2003 upgrade is available from o2 and wondered whether it was significantly better than the special edition?
of course, if there was a xda-developers special edition rom based on wm2003 that would be the best solution... :?
Nas

There are many WM 2003 ROMs and most of them works quite fine ... try the kitchen at www.yorch.net or http://lumpistefan.dyndns.org/

Just do it, upgrade it! I upgraded my Siemens SX56 with AT&T to 2003 and than cooked the rom from Yorch to unlock. By the way, it is a very good rom, thanks Yorch.
I did it with SD cards one of my XDA's, it worked perfect and quick: saved 2003 rom on one card, cooked Yorche's on another. The saving and installation was done through the bootloader as discribed in the proceedures in frequently asked questions section. The extracting and saving of Yorche's rom was done through OSImageTool in XDAtools into an SD card inserted in a USB card reader/writer (Inland 9 in 1 card Reader/Writer, $10 at Micro Center). The battery was fully charged on my SX56 and the flashing of rom's back and forth was done without the XDA being pluged to power unit. I tested the unlocking with a T-Mobile card, it recognised it, I made some phone calls with no problems, kept Yorch cooked rom for two days to get to know it and then flashed it back with my SD saved 2003 rom in my friends apartment just to show off how easy it is to flash the rom. it worked very well (it took about 5 minutes).
The 2nd SX56 was done all through ActiveSync with the XDA and card reader/writer pluged in and all synchronised (allscreen savers, power savers etc on PC and XDA OFF and battery charged). This XDA still had the original 2002 rom. The unlocking went very smooth. I did a full back up of the rom with ActiveSync. Since the cooked rom is PW10A1 and mine was PW10B1 I needed to get back my original rom to the XDA. The restore didn't work because it is a different partnership. So I flashed it back with my SD saved 2003 rom in a card reader/writer and OSImadeTool through ActiveSync. Everything was fine all the way to hard reset. I waited a minuteor so and did a hard reset and nothing happened, did it couple of times, nothing. It would not restart. I pressed the power botton and it went to bootloader mode. I did soft reset and the unit goes blank, dead. So I inserted the SD card with my 2003 rom into the XDA's memory slot and did the the bootloader mode, it took it, I flashed it. And now I have my 2nd SX56 with 2003 rom and the old radio stack ulocked working like a champ. I tasted with T-Mobile card and it works instantly, no configurations needed. Now I have to do a complete upgrade.
After all I like the new 2003 better but with some of the programs from Yorch Kitchen rom, which I installed and they work fine.
You, ladies and gentlemen, at XDA-Developers are the greatest thing that happened to the mobile devices community. I honor you and thank you. And Peter Poelman, you are the wizard, thank you.

Look here for the answers:
http://wiki.xda-developers.com/wiki/FAQ
and here to cook the rom:
www.yorch.net
check what you want or don't want and click Build ROM now, after it is done click Download. Before you build and download choose which file you want, exe or nb1. What ever you do backup your original rom preferably and safer to an SD card either through OSImageTools in XDATools and ActiveSync or the mode and the SD card pluged into your XDA
bootloader, and read the forum in details...
The new Mobile 2003 you can get at any of the provider or manufacturer of XDA's: www.T-Mobile.com, www.ATTwireless.com, www.My-Siemens.com, Microsoft has a list of manufacturers that have upgrades - www.microsoft.com/windowsmobile/resources/
Make sure you use the right one for PW10A1 or PW10B1 what ever your device Model No. is...
Good luck, John

John (and any others out there),
I hope that I'm not asking something here that is covered in some faq on this board and I think I've read them all, but...
I see mention of a lot of versions. 4.00.21, 4.00.01, A30.05, A30.09 etc...
Is there someone that can tell us new guys a little more about these? IE, what is it exactly, 2003, 2002, beta, final, alpha?
I recently bought a Wallaby, and want very much to use the MS Voice Command. Therefore, I have a definate need for a 2003 rom. I have read and reread the forums here and have a good handle on how to flash my rom, but I'm so confused as to what the best (read most reliable) rom to install, as well what radio version would work with the given rom choice. I'm not necessarily asking for a recommendation, but perhaps a nudge in the write direction.
Sorry to dump on you in particular, nothing personal either mind you! It's just that I'd love to read a FAQ for the different versions and what might be expected from them I guess. (I hope like heck I'm making sense here!)
Thanks!
Larry

Hello,
Actually, the only difference between ROM versions is bug fixing with newer versions, but the only significant factor is whether it's PPC 2002 or WM 2003 ROM.
For upgrading, I may recommend TMO 4.01.00 (my personal preference) or A30.09 (with a minor sound issue). If you need to unlock your device you must start with PPC2002 3.17 ROM first then select any WM2003 later.
There is no connection between the ROM and RSU. However, the RSU is the most sensitive part in the XDA. If you have a functioning RSU ... do NOT touch it!!
Last, get a SD card and take a backup ... it's safer and you can use the SD to upgrade as well.
Good luck ...

This is to Larry,
All these replies take you through the right directions. I have two Siemens SX56 devices with AT&T Wireless, both PW10B1, Pocket PC2002 (Ver. 3.0.12039), ROM Ver. A.20.17 ENG, RADIO Ver. A.20.10, 32MB Rom.
1st one I upgraded the day AT&T and Siemens released the Mobile 2003 free upgrade. As much as people complained, cursed and were distroying there SX56 devices ( what I read on AT&T forums) I never had any problems, and as a matter of fact the more I used the device the better it became. I played with it for about two weeks and then I decided to unlock it. So I placed my SD card into the SX56, started the bootloader, downloaded the original 2003 Rom image, soft reset the device. I cooked the Special Edition Rom based on 3.17.03 O2 ROM in Yorch Kitchen, I built the nb1 file, I downloaded, extracted with WinZip, put it on another SD card, put the card in my SX56 device, started the bootloader, flashed it, did a hard reset. It didn't ask me if I wanted to unlock it but the XDAunlock program was there, I taped it, it asked me if I want to unlock, I did. I checked it with a T-Mobile sim card, made a phone call with no problem (I tested with the same card before and after, before asked me for the pin number and after it logged in to T-Mobile network). I used it with the Special Edition Rom for about a week to see which programs I liked and wanted to install on my device after I flash back to saved Mobile 2003 Rom. I flashed it back with the 2003 Rom image. I was on the road, away from power supply, my pc, usb ports etc. Just the unit with its battery charged up, the SD card and the bootloader. It took 5 minutes.
My 2nd SX56 device I did before the 2003 upgrade, the original 2002 still there, with ActiveSync, OSImageTool in XDATools, SD cards, card reader/writer and nb1 file. This time I overlooked the saving of the original 2002 Rom and it went directly into the flashing with the Special Edition Rom cooked in Yorch Kitchen. I unlocked it, tested with T-Mobile sim card and flashed it back with the the Mobile 2003 Rom image saved from my 1st SX56 device. It didn't want to wake up after the hard reset. It kept going to the bootloader mode. So I inserted the SD card into the SX56, started the bootloader , flashed it back again with Mobile 2003 Rom, did a hard reset. It worked. Now I have my 2nd SX56 with new mobile 2003 Rom but old, the original Radio Stack from Pocket PC 2002. It works fine. The working is like the Upgraded 2003 device. Maybe with the older radio Stack is more stable on the signal, and I don't know for sure because I did not tested, only what I read and the people having problems. My preference is a total upgrade, the Rom and the Radio Stack, I noticed that the audio quality is better with the total upgrade, specialy when on the speaker phone during a phone call.
What ever you do save the settings and the Rom images and you do the right PW10A1 or PW10B1 (the Special Edition Rom is PW10A1). Make sure all the screen savers, power savers, sleep modes etc. are turned off on both the PC and the XDA device.
Good luck, John

Thanks, guys!
I kind of knew that the differences were a matter of bug fixes, what I wasn't sure of is which is 2003 or 2002. I'm going to keep reading here of course. This is a fantastic site to be sure!
So, bottom line is I guess I'm just going to pick a couple of them and flash them and play with them so which works the best.
Many thanks again guys! Larry

Larry,
Yes, exactly. I forgot to say that my new rom is an AT&T- Siemens: ROM Ver. A.30.09 ENG, Radio Stack A.33.02. The previous Rom version had a band switch (900 for Europe or 1900 for Americas) in the Settings and under Phone but now with the new it has an auto configuration which I like better. I can always search the network manually. By accident I found that if you set it to manual and don't have a network specified or any signal strength showing as long as the phone is turned ON, I can still get on Internet.
Good luck, John

One final ?
Guys
Is there ANY version of the W2003 ROM that comes with the Wmodem (or similar) application ?
I first came to xda-developers when I was trying to use my Qtek as a modem....thereafter we saw the O2 and Qtek PPC (2002) upgrades that brought in the Wmodem utility.
That seems to have disappeared off the priority list for most people these days, though.

How to downgrade RSU or swith from 900/1900 to 900/1800

Hi all,
Thanks to this thread http://forum.xda-developers.com/viewtopic.php?p=39630#39630 and especially remarks from hb88xx, I successfully managed to recover from my own mistakes (that many people have done as well apparently).
Here is the story:
* I bought my O2 xda from Telstra in Australia where the band is 900/1800. It is a PW10A1 device.
* I then cooked a rom with Yorch's kitchen and as many others, didn't read enough posts before doing so and opted for the infamous EXE method as I had successfully upgraded once before from O2 using this method.
* As my bootloader is 5.17 and my cooked rom was based upon T-Mobile, I was stuck: impossible to downgrade the bootloader because of TMO checks (the wallaby patch doen't work) and impossible to up/downgrade using the SD card method because of the bootloader version.
* Still, I could use my device but my WM2003 was very buggy.
* Out of hope, I decided to upgrade to another TMO rom, but this time an official one (4.01.16) as I read it was quite stable.
* That was the BIG mistake as I also did the RSU upgrade and I ended up with a 900/1900 device, having the 4.21 RSU.
* I tried many of the tips I read from this forum, but none of them worked and I had to buy a cheap cellphone to use my SIM card on it and keep my xda as a pda.
Basically, what you need to do is the following:
* Using the attached file or the official TMO upgrade, extract and copy the files into the \Windows directory of the xda.
* Detach it from the craddle and run the EXE on it.
* It says things in german (performing upgrade) and then a final status (whatever "erfolreich", ie successful). Click OK and finally, reboot the device.
* You now have a 3.23.11 RSU.
Once again, thanks a lot to all participants to this forum and especially hb88xx.
And thanks also for the remark below
Regards,
Bob.

Hey mate ...
It's great that you have learned this lesson, but now you may cause troubles to some unexperienced users by posting this file with this name
Simply, what you have posted is the typical RSU upgrade 4 files you should find in ANY RSU exe file, but because you posted this file with the name RSU_Fix, I 'm afraid some one will just use it with a B device thinking it will solve his problem and endup with a dead RSU.
So, plz remove this file or rename it RSU_3_23.zip or so

Hi BobMorane.
I am having the same problem as yours, upgraded to WM2003 and can't go back to ppc2002.
Sounds like You have reverted your xda rom to ppc2002, didn't you?
Don't quite understand those that listed in your post. Could you explain a little more?
Thanks.

XDA1 bootloader v5.17

Hi bob,
I'm a little confused - I understand RSU 4.21 is for 900/1800. It is the RSU that o2asia currently distributes.
My XDA is a PW10A1 and currently has RSU4.21 (from o2asia), Wallaby 5.17 (no idea where it came from... am guessing o2asia as well) and T-mobile WM2003 4.01.16 ENG (.EXE cooked from Lumpistefans)
As a result, I'm stuck as well. However, I can still use my phone on GSM900/1800; as long as I avoid settings-phone-band; all is well; but if I do wander into that, a reset to the bootloader-calander-gsm900/1800 solves the problem (albit temporary...)
Anyway, I'm meeting up with a friend to borrow a SD card+reader over this weekend or the next, so that I can change the ROM (get out of theT-mobile WM2003 rut). Am a little concerned about what you wrote however:

* As my bootloader is 5.17 and my cooked rom was based upon T-Mobile, I was stuck: impossible to downgrade the bootloader because of TMO checks (the wallaby patch doen't work) and impossible to up/downgrade using the SD card method because of the bootloader version.

Could you please eleborate more on how the wallaby patch didn't work? How did downgrading the RSU to 3.23.11 help? Are you able to replace your T-mobile ROM or Wallaby 5.17 following that? Or are you still stuck, but at least the phone works on GSM900/1800?
More information please?

Hi,

Actually, I didn't revert to PPC202 and I still enjoy the 2003 features, but I managed to get rid of a 900/1900 issue.

My problem was slightly different as I did not have the RSU4.21 for asian devices. My aim with the post was more to explain how to get out of the original T-Mobile rom lock-in (I did not use a cooked one because of my 5.17 wallaby). I assume you can do it as well with the asian RSU4.21. If you have it, I can try it and let you know.
As for the 5.17 wallaby issue, I was stuck in the midst of 2 issues : the 5.17 doesn't let you access the SD card method and you need first to downgrade it to 5.15. The patch to do this can't be used if you have installed a T-Mobile rom as it blocks the connection. I couldn't get around this and that's the reason I upgraded to the offical TMO rom.

Thanks for your reply, Bob.
So you are still with WM2003. Is this the new official one or the buggy one that you've had earlier. If its the new one, how did you do the flashing?
Did you downgrade the bootloader to v5.15?
I really wish to go back to ppc2002, as the current one seems to be quite unstable. At times, it reset itself, especially when some changes was made to some particular today plugin. It also turn on itself, which eat away the precious battery power. Also, the phone setting function and the band switching utilities will hard reset the xda.
Sorry for so much bugging. Hope your could help.
Thanks and cheers.
