UK 02 4.0.0.x PPC2003

Hi ya fellas.
I upgraded my XDA 02 UK pda to 4.00.05 and am fairly happy with its stability. A few probs with the backlight going off, but nothing much really. Windows Media 2003 is class.... encoding films with windows media codec 9 is a joy and they work every time...no codec conflictions, cache settings etc, and the quality is cool.
However, i wish to get a plain (i.e. No added cooked programs) ROM.
I could use Yorchs kitchen to cook up a plain 4.00.05 ROM again, but would rather give 4.0.0.16 ago. It's labled as a T-Mobile USA rom... I however have a UK o2 model xda. If i download the GSM 800/1800 changer utility with it, should it work ok?
Also, will this ROM update my radio stack. I'm currently running 4.21 (the official latest update for o2 uk xda's)... i dont mind if it does update it, but compatability wise, what odds am i running of it working ok?
Ive got an SD reader/writer and have a backup of my old rom just in case i need to go back via bootloader mode.
Thanks for listening
You XDA-Developers are good people (if a little to smart for my likeing
Tony Kett.

probably none since you're only updating ROM and not radio stack.
the cleanest method is obviously using the SD.
btw ... can we have your ROM to look at ?
Thanks
Decebal

my Rom (4.00.05) is just the one thats on the yorch site (with extra apps etc).

>probably none since you're only updating ROM and not radio stack.
- So if i update to 4.00.16 from yorch's site, theres no Radio stack upgrade? and the t-mobile USA version of this 4.00.16 (thats presented on the site) will only update my OS?
http://www.yorch.net/ - if you didnt know btw.
And a bloody good site it is.
So any other O2 UK XDA users upgraded to 4.00.16 or above? (4.00.21)?
I know your out there :!:

updating to v4.00.16 in the uk on a uk device will make you loose the ability to use orange/one2one in the xda as 1800mhz will be replaced with a none working 1900mhz
meaing your phone will have a 1800/900mhz radio but 1900/900mhz software which cant control the radio properly.
use v4.00.05 or v4.00.11(best option) so that you can use all uk networks.

4.00.11 ?
where can we get 4.00.11 ?

the rom kitchens :|

th 4.0.0.11 rom is not available on Yorch Kitchen.
It was on Jeff's Kitchen but the site is down.
Could some one upload the rom 4.0.0.11 on a server to share??
regards,
Yann

gazzaman2k... exactly the answer i was looking for. Cheers Mate.
Now to find a 4.00.11 Rom
Your right, yorch doesnt have that one. Anyone fancy hosting it.... or if possible, email me it at [email protected]
Cheers People,
Tony

So I take it that its not possible to change the 1900/900 to 1800/900 on those newer t-mobile roms (4.0016 & above)? No changer utility? Cant do it in the bootloader :?:
Dammit.
Just out of curiosity, what is the latest unofficial radio stack that people in the UK are using.
The 4.21 official one has been out for quite a while now, but ive seen no unofficial updates to this :?:
Tony

Ajektt, ther is an official update to the 4.21 Radio Stack it's the 4.21.X1
I have it installed, I don't see mutch difference, maybe a better signal mesure.
Doese some one have the 4.00.11 Rom?? I could host it if some one sends it.
Yann

actually with 4.00.21 comes 6.24.00 RSU.
Who wants it ... pm me ... or you can find it at yorch's site.
I need the 4.00.11 too.
Decebal

decebal, we are talking about o2 uk xda compatible radio stacks and os.
4.00.21 and 6.24 RSU Uses 1900/900 GSM ranges, not 1800/900 from what i've been told above in the forum.
Tony

will people pack it in emailing me for v4.00.11 yeah i have it but its cooked especially for my xda meaning the ecurity rom was cooked also :evil: if i had a plain version id be happy to share but as i dont i wont share the version i got as the rom contains my name+details and phone numbers ect.... hence why i havent uploaded it to my webspace and shared :shock:

Thank you gazzaman2k!! We understand you can't share your cooked version.
Maybe Jeff still hase in his archive an uncooked 4.00.11 version of the rom?
Could Yorch include it in his kitchen??
Dose some one has a uncooked version or a cooked version of the 4.00.11 rom with out the security option?

fair enough gazza 8)
We need to harass Yorch to get it up on his superb kitchen. I think we have our work cut out though, because he's getting requests left, right and centre for things on there, which is pretty harsh on him (and his team)
If anyone does manage to get the nbf file, so i can dump it in an .exe install that would be great

for all those concerned about the ROMs on Yorch.net:
Well, for those who know me know that I am about to get married in 2 months, and I just moved with my fiancee to a new apartment. Before moving, I sold EVERYTHING, that includes my 3 desktops pc (including my main PC), and my desk. Since my the new apt, is not that big, I chose not to buy me a desktop, but a laptop, by the way, the laptop that I just bought is the HP pavillion zd7000 series custom made for me :wink: , 3.06ghz of sheer power....arhhh, arhhhh, arhhh <----[trying to imitate Tim Allen]
Anyway, you problably know what that means, right, I've been without a home PC for the last 2 weeks, and I'm scheduled to recieve my new laptop by next week (hopefully), so no changes to the websites, and no changes, really, if you can get smart people to figure out the changes for me, I'm sure I could do them online or from my work computer, but in the meanwhile, I can't do anything......so stop harrasing me with the 4.00.11 rom already! 8) .

hahaha
Consider the harrisment stopped.
Enjoy your move... i moved 2 weeks ago and im still aching

If anyone can host the 4.00.11 Rom, i can send it via Email.
Got it in nb1 format, so it should work.
Played few weeks ago little bit with the kitchen, but didn´t get it really working. Maybe because my computer is too slow.
Regards
Stefan

can we get the 4.00.11 plain rom out of the nb1 file (nbf?)?
If so we should then be able to cook another rom on yorch's site (i.e. a 4.00.05 one), build it as an .exe. Then once we have the exe, we should be able to drop the 4.00.11 file in to replace the 4.00.05 one that we cooked...no?
But can u extract stuff from nb1's?

Windows Mobile 2003 Release date announced!!!!!!

T-Mobile Germany has annouced the release date for the Windows Mobile 2003 ROM for the XDA I as December 29th. Hopefully T-Mobile USA will announce something similar today. :roll:
http://www.t-mobile.de/mda/software/1,5193,7482-_,00.html

But this is only for German Model, isn't it?

hmmmm ... and how about the language version ?!
to me seems like only German is to be available ... too bad

Release date is now beginning January
Hope there will be an update....
Regards
Stefan

aren't we talking about the German version of WM2003 ..

this link was working few weeks ago with information about update but now seems to be dead.... somebody spoke with customer service and they said "in the middle of February" so we will see...
for me 4.01.00 ENG work fine
ps. pozdrawiam rodaczke

well, maybe there has been some minor problems ...
with that ROM release so they've decided to stop distributing for a while, hard to say ...
I presume as official release is hopefully coming with a short notice stick with current version I have

ps. rowniez witam i pozdrawiam

somebody wrote that 4.01.00 ENG is only good to US tmobile ppc owners because of radio ... I mean only for PW10B1 units ...
I did reflash mine yesterday with this version and I like it so far .... signal indicator doesn't look normal because I dont have signal but my ppc recives calls normally ....

mine XDA is also PW10B1 .... heh
now I know for sure that I have US version, thank you for the tip ...
dziekuje i pozdrawiam,

ps. out of curiosity, have you already get my private message ???

HI Monika,
Where did you get this T-Mobile WM2003 ROM?
Is it English version?
Can it be used in Asia?
Many thanks,

hello, I got it from http://www.yorch.net/ but I use an US version of XDA, for me it's hard to say whether it suits Asian hardware version, my rough guess is that Radio Stack version shall be different .... unfrtunately I have never came across the Asian hardware version
but before making any upgrades read that forum, e.g.
http://forum.xda-developers.com/viewtopic.php?t=4630
and also the other threads just to double check
regards, monika

Tks Monika,
But I see that you are using WM2003 T-mobile ROM 4.00.21.
From Yorch, 4.00.21 is only nbf file which is not nb1 so that I can't use the SD method for upgrading.
Any hint?

i have PW10A1 and i installed the v4.01.00 tmobile update i just downloaded an cooked rom from yroches kitchen then unzipped it all and replaced the nbf file from the v4.01 over the cooked rom nbf and flashes it that way works fine on english netowrks and i still have 900/1800 mhz just what ever you do do not go into phone options and click on the band tab if you do you will loose 1800mhz bank and then be on 900/1900 if you do this load up the bootloader click the calendar button and click on gsm 900/1800 and itll say reset or some crap do this then softreset and youll have 900/1800 back again but dont click on the band tab or youll have to do this.
gaz
p.s ive found it to be quite stable so far but seems to run kinda slower then v4.00.11 but it has improved features

hi
few questions
I have US tmobile Pocket PC Phone so it is type B so I flashed with no problem with 4.01.00 (RUUv2.04b_CEv4.01.00wwe_VS_Ozone_Test_(Integrate_Radio_6.24.01).exe) so I think that this soft will work fine with Monika's XDA if it is American....
Monika your XDA is from AT&T ? or TMobile ?
Is it ok to use it with European PW10A1 ?
gaz do you have exactly same ROM as I have ? (check my signature)
and this problem with band tab is only one ?
do you see TMobile logo when U do a soft reset?
Anybody use this soft ver. in Europe?

i use 4.01.00 with asian radio stack 4.21.01 with no problem
i used flash method when upgrading the rom
i unzip the exe file, took the .nbf file and write it to my sd card using OSImageTool and boot my xda with the SD card... 5 minutes later my XDA is running WM2003 with the latest ROM version :lol:
for asian users, do not open the band tab... if you do that, you have to go to bootloader and choose band 900/1800 to make your xda work again

Hi Toshiro,
I am a bit confused. The 4.00.21 nbf file from Yorch cannot be used by OSImageTool since I tried that before and confirmed by someone else in this forum. He said only nb1 file can be used for SD method.
Also, where did you get this 4.01.00 ROM?
Thanks v much.

Use XDArit.exe insted of the OSImageTool and you can write it to an SD card. www.yorch.net has 2 versions. if the newer one doesn't work, try the older one. I also found I have to unplug my cradle from my computer to get XDArit to work properly.

Upgrade PPC2003 ROM for UK XDA on T-Mobile?

Having cooked up a nice ROM from yorch.net I'm not sure if it'll work yet... Would someone tell me if its 'safe'?
I got the 4.00.05 version (PPC 2003) but doesn't say on yorch.net if its for the US/UK etc.. and want to upgrade it on my XDA device bought in the UK, will this workt? Or is my device never going to work again or pick up a signal in the UK if I do this? I'm currently using my device on T-Mobile network, and don't want to do this if it falls over...
Thanks for the guidance!

Yes if you've cooked the rom it will be safe, as its only the CE ROM. If in future you download a rom from a provider for example, that hasn't been personally cooked, you just need to ensure it doesn't also include a Radio ROM upgrade, as putting one on from the US will damage your device.
HTH
Neil

I did the build of the ROM on yorch.net making the .EXE package, I'm guessing that everything gets installed through Activesync, is that right? Or do I need to manually do some 'work' here?
Thanks for the response!

i-mate Radio v1.05.00 WWE versus v1.10.00 US ?

Hi, has anyone figured out what the difference between the i-mate Radio v1.05.00 WWE and the v1.1.0.00 US is ?
Any one using the v1.10.00 outside the US ? Any problems or hints ?
Torsten

hey,
As far as i know, the (1.10.00 radio version) is meant to be used only in the US, or at least on 850 networks. so i guess u can't compare these two.

hmm, i upgrade to 1.10.00 usa radio and its fork fine!
i use it at european gsm (russia, dalsvyaz) standart 900/1800.
but i don't know which things changed
anybody knows ?

where to get it and i will give it a try... we use here gsm 900....

I wonder if this will fix the problem some of us are having with the 1.6 ROM upgrade with not being able to re-connect to GPRS without a soft reset or switching flight mode on/off. Any thoughts?

to many drinks on my side!
This is a quote from the i-mate
ROM builds with radio versions 1.05.00 and 1.10.00 all include audio enhancements for voice calls. They also contain the improved camera driver. We are working hard to deliver these new builds to our full suite of languages.
indicates PM10C, then the customer should upgrade with the North American JAM ROM Build.
If the model number indicates PM10A, then the customer should upgrade with the Generic Worldwide English ROM Build. You will not be able to install the North American JAM (850) ROM. This WWE build does not include the connection settings for the US operators found in the North American build, though these are all available to download separately from clubimate™.

@Mashie,
i have the same problem my gprs keeps disconneting on and off... sometimes it works for a few minutes and then start disconneting.... and i have to do a soft-rest to get it to work again....... does anyone else has the same problem?? or a fix?
@alexk,
Can you hear me now? can you hear me now?

@torklemm,
i installed the 1.10 radio and it's working fine... i felt a better voice quailty than the 1.05... and works in 900 networks fine

Where can we find this radio version? Can somebody post a link to it? Thanks

PapaDocta, how did you install it?
Do the usual, unzip and delete all .nbf's except radio.nbf?
Or is it more complicated?

thks all for sharing experiences, just managed to upgrade (only) radio rom to 1.10 (the JAM USA one). I used all the files except the NK_ , the ms_ and maupgradeut which I replaced with the maupgradeut_NOID that I downloaded from the ftp. USB connection in Activesync was disabled and I put my mini in bootloader mode before the upgrade...... and it went smoothly.
My network is also 900 and it works just fine.
Signal strength, comparing to 1.05 is the same, only it seems that the GPRS icon is always shown (when it's available) which was not the case with 1.05

here ya go... and my way of upgrading was i didn't disable anything just run the maupgradeut_NOID once and the device went into the bootloader mode and i got the country error i ignored it and run maupgradeut_NOID again without resting the device.. and all worked but i advice using the above steps cuz it has been tested before...... here is the files you requested and i renamed the maupgradeut_NOID to maupgradeut so don't panic ;-)
enjoy

Thanks a TON for this! I installed on my S100 and the GPRS now works perfectly. I can connect and disconnect without having to turn flight mode off/on.

It depends on how you are upgrading. If you are using the files in the .rar file that Papa posted then you need to run MaUpgradeUT.exe and it will put your device in Bootloader mode. Once you get the country ID error, I closed that window and ran MaUpgardeUT.exe again and the upgrade went flawlesly. Hard Reset to get out of BL mode and set your device back up.
Hope this helps...

Do I need to backup the RAM or ROM before upgrading radio's ROM?
Does the radio 1.10.0 USA means for O2 XDAII mini?
Thank you in advance.

if you don't have problems with ur current radio then don't upgrade... if you just curious then go for it.
good luck

Thanks papadocta.
Well, I am curius :lol:
Beside, I hope 1 extra bar signal strength (that reported by those upgraded to 1.05.0 WWE and 1.10.0 USA) will save my O2 XDA II mini's battery longer.
Is it correct that 1.10.0 USA is newer than 1.05.0 WWE? Because I read somewhere is not always true. Anyone can confirm?
Thanks again.

New TMOBILE Rom Update

T-Mobile have released a new ROM for their MDA, which can be downloaded from T-Mobile here.
No exact details are available as to what is changed but users are reporting improvements in:
- "G" icon replaced by an "E" icon indicating EDGE connections.
- Hold down the wireless button toggles between silent/vibrate mode and ringer-on mode.
- Signal acquiring issue resolved.
- A2DP implemented.
- Startup time is much faster after a soft-reset
- Signal strengh is more reliable and stronger
- Reduced sync times
- Enhanced Communications Manager
- "Lock/Unlock Device" item added to Today screen
- Changes to Signal indicator on top bar
- New Network Connection Settings added
Plus is reportedly upgrades the machine to AKU2.3.

sweet... but don't i have to do some crazy thing to my MDA to beable to get this ROM on there? I heard updating the ROM is hard

I am running this ROM, and I can tell you it is not too hard to do. Start by downloading lokiwiz from here.
Specific directions are included in that thread, but it is as simple as copying the enable RAPI cab to your device and running it, and then connecting the usb cable to the computer and running lokiwiz. do both the Super CID and the SIM unlock now (this may not be nessesary if your device is a t-mobile MDA, but it is best to just do it now, just in case...)
Once you are unlocked, it is as simple as downloading the ROM, connecting the USB and doubble clicking the installer... Follow the prompts, and you have a new ROM
I personally am running the 2.26 T-mobile ROM, and I really like it... If you haven't upgraded from the stock rom, I would reccomend giving it a try.
I hope this helps... And If you have any questions please let me or someone else know... It is better to ask a stupid question than fry your wizard...
EDIT--- The link to Lokiwiz I posted is to an upgraded version that I don't know how to use, it appears it has been upgraded for the newer ROMS, but dosen't work the same as the older version... If you have an MDA I would try the upgrade without it.... SORRY

Yes it does Change Everything
IPL: 2.26

Protocol Version: 4.1.13.12
OS Build version: 14955.2.3.0

Don't know if you can adjust you topic title but there are a few threads already running in the "Wizard Upgrading" section.
You're talking about the T-Mobile 2.26 version. That's not realy new. So if anybody wan't some answers just check the "Wizard Upgrading" section. 'Cause that's where it should be

Ah damn! I just upgraded to 2.24, is it worth doing this uprgrade?
If I installed all my programs to my Memory Card will they still be on the program list or will I have to load them all up again?
CHEERS!

Ok, maybe a silly question but...
Can I put a US carrier's ROM on my UK phone? Like the radio stack is compatible and all that?

anyway, thanks.

anyone no longer need nullkb?

hey - where did you find the site http://www.t-mobileapps.com ?
does TMobile publicize this site at all? (not that it seems to show much)

In previous stock TMO ROM, landscape mode with keyboard open popped up the virtual on-screen keyboard. I used NullKB to keep that from happening.
Now, with the new ROM released today, the virtual on-screen keyboard doesn't pop up in landscape mode.
Just checking with everyone else.

Yep, I've already did with xelencin's 2.24 T-Mobile rom from this site. One catch though there is a slight difference in the keyboard layout between the U.S. and U.K. but you can fix that by a reg. hack.
Use Total Commander and add the hack :
HKCU\ControlPanel\Keybd\Locale = 0809 hex
I have a O2 XDA Mini S using the U.S. T- Mobile rom. I haven't upgraded to the new rom yet.

The link I believe is part of T-Mobile's parent company. If you login to your T-Mobile account and select MDA as your phone, then click the link "support for MDA" at the top of the screen it will take you to another screen which has the link "System Upgrade"

Kind of ironic, I was just browsing around before posting about where to find upgraded ROMs!
I'm running a UK Tmobile MDA Vario, but I'm in Canada. Just to be sure, if I download this ROM and then do the keyboard registry hack, I should be good right? I'm still on ROM version 1.6.2.4 WWE
Thanks!

You should be, I'm in the U.S. and won the UK device from www.4WinMobile.com . It was running software branded by the company O2, I flashed it with a U.S. T-Mobile Rom and haven't had any problems. The only real difference in all of the HTC Wizard devices is the Version of WM5 Rom your running and the Extended Rom put out by the company selling the device. (I am in no way an expert this is my understanding from what I have read,)
I hope to have time to upgrade to the new rom this weekend.
