Hi,
Can anyone using WM2003 check to see if they have a "MORE" tab under Phone>Tools>Options and let me know the version.
The 4.00.11 version of WM2003 I got from Jeff's Kitchen does not have the "MORE" tab dispite the Microsoft Mobile site saying it should have!!! :?
mine does
Mine does. Its a USA 900/1900 T-Mobile device with 4.0.16 OS, 6.24 radio.
BTW: The radio version alters whats in Tools-options. e.g. the USA devices have a 'band' tab.
cheers,
..lance
Mine does not. T-Mobile device, 4.00.16, radio 6.24.00. Another device here with the same versions also does not.
Maybe this is related to a SIM feature?
nope
Mine does not. PPC 2002 on my XDA had it.
I've got an O2 XDA with 4.00.16 and Radio 4.21
I have got both the More and the Band tab.
Dear,
If all ROMs of yours are from Jeff's Kitchen, I think the presence of "More" option is optional when you cook your own ROM.
Thanks for the info guys,
I think it's a "feature" of 4.00.11, but I will check on Jeff's Kitchen for Ken_xda's suggestion when it comes back online. As Aurora13 has the same Radio as me but a different ROM, I will try an upgrade although I would rather have a UK ROM than a US one.
Mine does and I'm running a T-Mobile device, ROM 4.00.16 and AT&T radio stack A.20.10.
BTW my ROM came from a bin file install that I downloaded
from Aurora13's FTP site when it was active.
HTH
I too have just upgraded to ROM 4.00.16 and radio v6.24 (thanks Qman)...I do not have the "More" and "Band" options either - I remember having them under 2k2. Are these features important enough to request Aurora13 to repost the bin file? Should I revert to 2k2?
Good question!
As far as the "Band" option goings I'm sure you're safe if you plan only to use the phone in the Country/Region that your SIM card is set to. If not you
can always change if from the bootloader.
Now as for the "More" option goes it has the following Options:
Automatic pickup
Answer incoming calls without pressing Talk after xxx rings
Hardware button lock
Lock all buttons except Power button
Do not lock buttons
Broadcast Channels
Enable

Can this More" option" be retrieve any way on WM2003 4.00.11 i.e setting :idea: :?:
Hi All,
I've done a bit of fiddling. I downloaded ROMs for 3.17.00, 4.00.05, 4.00.11 and 4.00.16 from Jeff's Kitchen and tried all of them with Radio 4.21 from UK O2. The only one that gave me the MORE tab was 3.17.00. none of the 4.00.xx versions did.
I would like to try with a different Radio ROM but I don't have the previous version prior to te upgrade to 4.21. Can anyone tell me where to get an earlier version.
Hmmz strange I have the O2 Radio 4.21 and the 4.00.16 (kitchen) ROM, but I DO have the More tab!
O2 XDA with 4.00.16
Hello, Posible to download O2 XDA with 4.00.16 or 4.00.11 (not ROM Kitchen), where ftp? or site download?
Thanks
Wow you can download a XDA? I had to buy mine in a shop!
Maybe we can download the O2 XDA II already somewhere?
But seriously: if you don't select the extra options on the kitchen page, you get a 'standard' 2003 ROM.
The band-switching feature is particularly important. Any time I've ever switched bands using the bootloader method (using bootloader 5.15, ROM 4.00.05, Radio RA.20.10) I always seem to end up accidentally doing a hard reset. Very frustrating. I've learned to always backup to SD first, but what a pain. I travel to Europe reasonably often (just got back from T-Mobile country (DE) yesterday) and would love to have the tab back. I just looked at Jeff's kitchen again, and I can confirm that there's no option there to add the More and Band tabs (there's an option to add the BandSwitch program, but as the page says, and I can confirm, it doesn't work with the 4.xx.xx ROMs).
I'll try 4.00.16 to see if the Tabs come back.
PS - That config (ROM 4.00.05, RA.20.10) has worked great in UK and Germany for me... I've roamed all over and get as good as I can get considering I'm running at 900 while I'm there.
PPS - Maybe this has something to do with stk.lnk or HTC SAT (/windows/stk.exe) which seems to always hang at startup on my system?
No Band or More Option and HTC Sat Also Hangs
I've upgraded to ROM 4.00.11, Radio 4.17.00. I do not have the More or Band Tabs.
I also suffer from HTC SAT hanging at bootup.
Otherwise everything good.
I have an O2 XDA and in Australia
i was surprised that my clock did not adjust automatically to eastern daylight time sunday. is this normal, a bug or am i missing a setting? it was easy enough to reset but i figured either the windows os or the tmobile would have taken that into account. (even my old c332 adjusted automatically in the spring) thanks in advance.
It happened to me also. My previous PPC2002 based ROM did it without any problem.
Crash,
My XDA I with WM2003 changed my time automatically over the weekend, so it does work. Now I looked all over my unit but for the life of me I cant find a setting for it.
Hope this helps somewhat

i'm running the 4.00.10 version with the new t-mobile radio 6.24. i think i have 4.00.16 from the kitchen around but haven't gotten to loading it.
mine done it too im on v4.00.11 put the time back 1 hour like it should of
Clocks
When did the clocks change? Who said they could? Why wasn't i told? This could explain a few things, like the funny looks at work. Oh well time to hibernate i suppose.

FYI
Daylight Savings Time is handled via your Windows powered PC/Laptop and Activesync, hence no settings for it will found on the device! 8)
HTH
no windows CE auto does it :| mine want on activesync when it done it it was on my desk and the device turned itself on :| and the box appeared
saturday night i were told that at 2 or 3 it the time would change i dident notice but the next morning it had gon back an hour
it dident sync with my puter
but did it by it self
Ok do this open ActiveSync then go to Options there's a box thats says
"Synchronize mobile device clock upon connection" if its checked guess what else it does if your PC/LapTop is set for DST, you got it!
It puts a "1" in your DST Registry Setting in your devices Registry (hence automatic time change), now guess when this is done, you got it! Its done when you first create a Partnership! Well at least thats way it use to work, maybe times have changed! :wink:
Take a look at the below registry key on your device:
[HKEY_LOCAL_MACHINE\Software\Microsoft\Clock\HomeDST
BTW a soft reset may reset that "1" back to "0" if I remember correctly anyhow HTH.
Synchronize mobile device clock upon connection" if its checked guess what else it does if your PC/LapTop is set for DST, you got it
yeah that dont do daylight savings thats no to do with it! thats to do with making it the exact time it is on your pc to the millisecond as in sets it to your computers clock time
my xda updated the time without having been connected to the caddle at that time
I unfix sync kabel from computer (between Sunday to Monday) and time has been changed - T Mobile MDA 4.00.11.

Hi guys,
I have just bought an o2 xda ii and am having serious problems
was trying to establish a bluetooth connection with nokia 6600 and it just froze displaying the today screen
now xda hangs after switching on and nothing works only the bluetooth light keeps on flashing
cant try anything as it doesnt function at all.
Can anybody help
Isn't There anyone who can help me...??????
Isn't There anyone who can help me...?????? :roll: :roll: :roll: :roll:
when you mean turn on do you talk about turn on as in turn on the top power connector
or a softreset ?
if you mean top power connector then that dont reset the pda you need to do a softreset
if you did mean a softreset then i dont know any other way then a hardreset which of cause delete all your data
Inderts the stylus in the reset hole, if that doesnt work then as the man said you will need to do a hard reset and all data will be lost, hard reset is done by pressing power while inserting stylus in reset hole.
Hi
Thanks for yr reply
I have aslo tried a hard reset but no luck
The device switches on and freezes on the blue O2 screen or sometimes goes thru the setup procedure & freezes at the today screen
Tried it a couple of times
Is there any other way please let me know.
Thanx again :? :? :?
Which ROM do you use? You can try to flash your ROM. There are plenty of treads on this forum on how to do this. Make sure you don't use a USB hub when connected to flash you're ROM. Your MDA II must be connected to a normal USB connection (I learned it the hard way....)

Hi
Sorry for the late reply as i was out of town
Dunno exactly how to identify the rom version but when switched on it shows
R 1.05.14
G 1337.14
D 1.03.00 USA
Can u please suggest what to do
Thanx
You can see which ROM version you have by going to:
Settings, System tab and then Device information.
Mine says:
ROM version 1.60.00WWE
ROM date: 12/03/03
Radio version: 1.06.01
Protocol version: 1337.16
ExtROM version: 1.60.06
So I guess you can do a ROM upgrade. To find out how to do it, just do a search on this forum for ROM upgrade and you'll find detailed describcions on how to do it. Make sure that your device is not connected via a USB hub otherwise you can have some trouble getting it done.
Wouter
Thanx for the prompt reply but the problem is that the device starts goes on thru the new device setup programme & hangs nuthing beyong that
So am unable to go to the system settings
Is there any other way i can see the rom version...
Well the colors at the beginning tell you which ROM you have (but are only very short on the screen so hard to read) but you can defenitely upgrade.

No Bluettoth Hardware Installed Error Msg
Hey, this sounds like the same problem I have too! I have just posted a new subject in the "Using It" section of this Forum. Does your device also suffer from the following i.e. when the software ha loaded and you hit the bluetooth icon, does this error message come up "There is No Bluetooth Hardware Installed on this Device"? Pls read my post below.
"I have an XDA II, bought from the UK. I live in E. Africa so sending it back is a hassle. EVer since I bought it, although it was OK for a few days, a msg then came up saying "There is no bluetooth hardware installed on this device". This means I cannot put b/t on or off. Also, it affects the performance of the XDA II as it crashes frequently and loses ActiveSync connections frequently. The odd thing is that SOMETIMES, after a hard reset, it's OK again. But then when I do a subsequent hard or even soft reset the same problem occurs! So it DOES work. But not consistently. I conttacted O2 by email & tel. They were semi-helpful. I returned the XDA II to the O2 repair centre in London by courier (expensive). It came back, apparently repaired, but they had addressed the wrong thing and the problem still persists! I am loathe to sending it back without trying something for it - if you have any suggestions. Perhaps I can try a Rom Update or something to see if it sorts it. Even O2 are baffled, but I do not have the privilege of sending it off again because of where I live. Any suggestions or advice please? Many thanks. "
'Frozen' O2 screen with bluetooth light flashing
Hi to all,
I 've been having similar problems since I got my unit last November. You may be able to relate with my problems.. screen won't respond to any taps.. when you send SMS, the 'Send' button freezes... tried soft resetting, sometimes lucky, gets back to normal... at worst, does a hard reset...
after a few months of no reliable answer from local and foreign XDA help.. i'm used to either removing my battery/sim.. wait for awhile.. try to find a place where there's better network signal.. then, puts back the SIM and battery.. many times a get lucky by doing this... but there are also times that I had to do hard reset.. like two hours ago..
Hopefully, some help will come ...
For those who have yet to develop a routine to address similar problem, you may try mine...
Helpless xda II fanatic(???)
Archel Angeles
I have similar experience too. I got my XDAII last November, it runs smoth without a single hang for the first month until one day in January, while using it reboot by itself, after that day the device will just reboot anytime anywhere!
Thinking that this might be caused by some installed softwae, I hard reset my device. After the initial setup then it hang while running the auto installation from the extended rom saying that some file is missing. I hard reset again and it still hang while running the auto installation but saying another file is missing. On the day alone, I hard reset my device for more than 10 times! Each time it will either hang on the O2 startup screen or during the auto installation. Until finally one time manage to pass through the initial setup and auto installation.
On the second day, I quickly bring my set to the service centre for repair, while I describe and showing the faulty set to the service officer, the device self reboot for another couple of times.
I took back my set two days later, the service officer told me they cannot find the fault of this so they re-flash the rom for me, and they have tested it with internet browsing, mms, sms etc without any problem.
The 'repaired' set works fine for another one month until couple of week ago it start to hang during some incoming calls. When call was received, I press the answer key to answer the phone, the device would just hang with the ballon still showing on the screen, i'm not able to answer the call at all.
Last Friday, I finally hard reset the device again and re-install some my software applicaton and games. Second day morning while I was waiting for my friend, I start to attach photo to my contact, just when I attached the first photo and click on the save, the device hang! I press the soft reset button and the screen goes off without rebooting. I press the reset button again but the screen just won't come back. I even took out the battery and put in my backup battery, still the screen refuse to come back! The screen only come back when I performed a hard reset.
Today i found another problem with the device, the free memory is getting lesser and lesser by itself! Just before I type this reply, I soft reset my device and leave my device on the momory status screen, the allocated momory for the program showing 63.02Mb, in used 16.96MB and the Free momory 46.06MB. Now the in use memory increases to 30.75MB while the Free memory drops to 32.27MB!! I did not run anything in the background, I did not even tough my device!!
Anybody here can help save my device?
I have the same problem now. It is really a nightmare for all of us!!!
Exactly
Have a very similar problems 4 days in the row. Self-Blackhangs without any knowing reason. Impossible to use device longer then 10 min. HELP!!!
P.S. Some days before I try to uninstall Intellisync, wich I try, but does not use for a long time. Uninstall was unsuccessful cause .exe was "in use". There problems begins. May be. After one of hard-resets I remove .exe manually and then uninstall prog, but problems persists.
Hi guys, Fortunatly I do not have the same problems with my XDA II but I was thinking maby it is a type of software that has been installed on the device, I have noticed that some apps can cuase VERY strange things to happen (Even some THEMES!!!).... LOOK out for this..
Maybe you could try and run the XDA II after doing a hard reset as bare as possible... As in not installing any other themes or thirdparty software for a day or two and see if the device still gives your any problems... Will be interesting to find out.. I have had resets on my XDA II from using some themes avalible from the O2 website (that users have made not O2, but still) and since using the default theme I have not had a crash or a reboot since... (THIS TOOK ME FORVER to find out)... but might be worth a try..
Keep us all informed how you go with things.. Hopfully its just a pice of software or somthing simple like that...
GOOD LUCK ALL!!!
So, guys, I think that there is a HW problem. MDA freezing during initial install or during HardReset before install. Maybe "motherboard" is microbroken or so on.
Week ago I return my MDAII to T-Mobile and they will repair it to some way. I will report this way to you all as soon as possible. Let we see.

Hi all,
I have the following devis info of mine:
ROM version 1.66.00WWE
ROM date: 02/20/04
Radio version: 1.10.00
Protocol version: 1337.18
ExtROM version: 1.66.101
This Rom works great, just search for it and upgrade!!
Wish you all luck!!!
sounds a lot like the problem I'm having.
Can any of you guys install a new rom at all? mine freezes up and activesync disconnects the second it does... So I guess when flashing your rom and having it freeze up on you, you'd be even further from a solution... thoughts pls
I fixed it guys...
seems a corrupted rom was the problem hitting bootloader mode (power + action + stylus) and installing a new rom fixed my problems
let me know how it works out for you guys
i removed the 02 logo from the top of my xda2 now my phone dont refresh the desktop correctly, how do you reinstall the 02 software?
thanks in advance
I have seen this after I uninstalled O2 Active. Just do a soft reset and that should sort it out.
just tried that, no luck, thanks tho
Did you unistall both O2 active and the O2 Active installer?
v2r setup o2activeuisetup is still in remove programs, should i uninstall it
Yes I think so. I certainly did and I managed to get rid of the problem. If I remember correctly, I uninstalled the v2r setup o2activeuisetup first, then uninstalled O2 Active. Im sure the solution is there somewhere
just tried that, still the same
If you are prepared to do a hard reset, then I suggest you do that, then uninstall the V2R setup then uninstall O2 active - with soft resets in between. I think thats how I did it.
ok, once i have backup my settings i will try that later this afternoon
OK. Please let me know how it goes.
will do, wont be untill around tea time tho, around 1800
ok, just tried a hard reset, got the screen back, i followed your instructions, but it still went the same, half missing / corrupt
Having just upgraded to the new O2 ROM, I had the chance to do this myself.
The solution is very simple .
Before or after uninstalling O2 Active, go to Start/Settings/Personal/Today and select a different theme than the currently selected one, and tap OK.
I just did this and I got a nice clean Today screen.
i can also confirm that DCS has hit the nail on the head as i had the same prob and this is how i resolved it (i chose the spiral theme coz its quite nice and it will do for now until i put my cartoon skull and crossbones back on)
Hi everyone,
I would like to kick start a thread for any application installed in the latest SE rom by mystery man. The rom seem stable nevertheless some apps seem do not really prepared for the changes. (i mean from WM2003 to WM2003SE). Let begins........
1) Battery Pack Pro v1.11-will make your today screen screwed up. How? Go Start-Settings-Today-Items-then click OK and closed it-you will get what i meant here.
Will continue to report.......
Best Rgds... :lol:
Wisbar advance freezes and requires soft reset after telephone has been used/or whilst attempting to dial.
XCPU Skalar - you have to update to version 3.85, lower version keeps system to hang
Tillanosoft Pockettweak - update to 4.2.7, lower version destroys font settings
PocketZenPhone - update to latest beta 11 version, older versions are not able to switch phone on again
Can someone tell me what is the function of "Today timeout" which constantly showed 4hrs at Start-Setings-Today?
Well why must that function included in the today settings? The problem is now and then my today screen showed nothing or clean even though i unchecked the Today timeout box to disable it.
After all i suspect something is not right wif the Today timeout option and nothing to do wif Battery Pack.
Anyone experience the above problem? :roll:
Calligrapher 7.4 (just only 7.4 ,older not has this problem)
after i install and use for 15 sec. ,then screen is locked up cannot tap anymore but Button still work.
I do soft reset and disable it then 15 sec ,screen lock again.
Only one way to solve it by using cradle sync with desktop and select remove calligrapher and then soft reset ,it will work normally again.
It may from defect in version 7.4 or conflict with XDA II.
PLease take care ,if you decide to use this version
Problems with SE (both dcs's & mysteryman)
Hey there guys!
I used this weekend (in fact starting friday evening) to upgrade my T-Mobile MDA2 from ROM 1.72 (radio 1.14) to ROM 2.xx and radio 1.18.
Although I did a lot of reflashing up to now - I want to thank you all guys for this forum, because everything I've learnt about my PPC is from here. It is shame that I cannot contribute via paypal because Bulgaria is not included in their country list.
Now.. Here is what I've experienced with my mda:
I upgraded from 1.72 T-Mobile WWE to 2.02ti... All cool - until I started to load the device with programs. I mean - it is cool and fast and nice and colorful..
A guy mentioned that SE boots faster - I can's say that - the phone would show the first boot picture, then fast will change to 2nd and then (in 2 to 5 seconds) the bluetooth led will flash (if at all) at least 5 times and then it shows the today screen or will stay there forever :-(
I understood that:
* xscallar 2.8x would not work - it freezes the system;
* sbp pocketplus 2.1 would hang the system or/and the today screen;
* sprite backup 3.0 hard-resets the system (3 in 2 times after finishing scheduled/normal backup);
* gprs monitor 2.12 would hang the today screen;
* cleartype is a way worse than in 1.60wwe
* if the system works, compared to 1.72 - it is flying! but :-(....
These problems appeared both in 2.02ti and in 2.06, no matter what extended rom I install (if I install any at all - because thru tears I tried that one too ;-) )
The (X) sign for closing programs disappears constantly and some programs could not be closed or [ok]'d :-(
Bluetooth 1.5x would either not work properly or would not work at all.
about the extended rom - i noticed this:
MMS15024_WWE_Hima_OzUp.sa.CAB, despite the lower version compared to MMS2.0.0.13 incorporates in the outlook folder and doesn't take additional space in the today screen. Also it provides sending restrictions as 100K, 200K, MAX - ;-) which is kewl 'cause I missed the ability of my SonyEricsson P900 to send unlimited in size MMS messages.
CallerIDB10, provided with 2.x SE versions cuts about 4 pixels from the bottom of the CLIP pictures and I don't like it - it has no new features or anything
For conclusion:
I liked the look of SE versions - it is really neat and fast - when it works.
But non of my really needed sofware would work as expected.
I went back to T-Mobile 1.72 (edsub's version) and I will tell you guys - there is nothing as stable and fast as it is.
This is my first post here, and I read this forum for more than 8 months. You guys rock!
Yours,
Dean

I had a big problem with 2.06-mystery man . Stuck on the every second
boot . So I had to do Hard Reset all the time.
After that I switched to 2.02 and all I can say its the most stable ROM
I know from 1.60 .
The reason I am posting here is :

I've notices that 2.06 sometimes freeses during boot when SD-card is inserted. It boots normally when SD-card is out and inserted when device finishes booting.
Cleartype in 2.06 can be tuned to look fine with cleartype tuning tool from Microsoft. I can upload it if needed.

Spb PocletPlus 2.1 is stable in my 2.06SE. The problem i encountered is the unstable widcomm bluetooth stack ( 1.5.0.801 ) which always "could not correctly initialized - BTTrayCE.exe) . can some one post some registry tweak for this?
@ mamaich
can you post the MS cleartype tuning tool please? thanks! :lol:
Phone Profiles is another one....
Using Phone Profiles 7.5 or 8.0, there is a dialog on reboot, 'Can't Find Window", (something like that), and it will not continue booting, only solution is a hard reset...
I can confirm the Calligrapher 7.4... will lock during boot, hard reset

Mine is working fairly well... I did notice the same problem you have, but I got around it by holding in the reset button until it reset itself (normally 5 secs or so). It resets fine every time. This is a pain compared to 1.66.00WWE. I haven't tried 1.72 yet. I would like to persist with the 2.06 version to see what bugs it has.
Recrem...
UPDATE:- Installing XCPUScalar Version 2.85 has completely cleared up the reset hang problem. I have configured it to auto start on soft reset, and minnimise on start. I have now reset well over 10 times and it resets as it should. I have XCPUScalar set to a min speed of 400MHz though...
I have only one problem with wm2003se 2.06 - at every call speaker mode turns on automaticly
