Upgrade US Version ENG ROM with a German Version from T-Mobi

Hi,
does any one has experince in upgrading a US T-Mobile Pocket PC Phone Edition with a German ROM Version ?
My concerns are that the German versions are supporting different GSM frequencies than the US Version. And I read here that you never should upgrade a German phone with a US version it will ruin your phone but if I try to upgrade a US version with a German Version does it also ruin my phone ?
Is this a problem ?

I think, that there should be no problem, to use the German Version in your US-MDA, if your just upgrading the RUU - File.
This leaves the Radi unit untouched.
But i don't know what happend if you use different languages in the RUU and RSU files....
Regards
Stefan

You may be disapointed. The CE part DOES contain band specific information. If you update a USA unit with a European build you will no longer be able to switch between 900 and 1900 band operation.

The Us device is Model PW10B1 and there is no german ROM Upgrade somewhere out there (but if you can find a matching one, please tell me...)
I wouldn't try to upgrade if you still want to use the band-switching function 900/1900.

ROM 4.00.01 and DualBandGSM ?

I have just ugraded my Qtek ROM to vers. 4.00.01 (pocketPC2003) and the RSU4.21.
BUT since then I cannot see my mobile carrier anymore Orange CH (switzerland), but all the others...
Could that come from the new soft not supporting dualbandGSM 1800 ?? or naything else.
Thanks for you help !!!!
PS CAN I DOWNGRADE MY ROM TO 3.17 FROM THE O2 web site??

i believe that the current 4.00.01 is with the US radiostack
leaving your phone at 900/1900 and not 900/1800 which is the EU std

European XDA/MDA with Radio Update
Same here in Germany. First I upgraded my TMO (Germany) MDA to ROM 4.00.10 without the radio upgrade. It worked (and still works ) very well with the old (by only supported :? ) radio V3.23.00 protocol 32S54. The only thing I noticed is: the carrier (T-Mobile Germany) is not displayed (in the Today screen) and the connection bar graph is changing very often from "good" to "worse". :shock:
After this success I upgraded also the radio unit, but I better have not done that! No (neither 900 or 1800) carrier is detected by the phone anymore I tried a lot in the bootloader but nothing helped me
So I downgraded the radio to 3.23.00 with the RSU utility which is downloadable from TMO Germany. And everything is okay again

Radio Stack 3.17 FR
Seems the same problem... but luky you are, as I don't have the older RSU available...
Does anybody know where I could find the RSU 3.16 or 3.17 FR ??
Thanks in advance,

I don't know if it works but why aren't you flashing the RSU with the one from the english o2.co.uk site ore the german one? Isn't there a support page for your french xda? (From witch provider was the xda sold? AFAIK orange has its own new SPV)
The English rsu seems to be ver 4.21 and is located here http://www.o2.co.uk/personal/xda/docs/Radio_Stack_Upgrade_v421.zip
The German RSU is also V4.21 but I don't have a direct link. Just click http://www.o2online.de/o2/business/datenloesungen/xda/downloads/index.html and go ahead.
The RUU seems to have the version 3.17 (UK) or 3.19 (Germany)
Look here http://xda-developers.com/rom/ RSU-> the "Phone BIOS" and RUU->"The PDA sw" So I think the RSU is not written in a specific language but only for a special region (US and Europe). But the RUU is.
HTH, Chris

problem solved
I actually could solve the problem by going in the bootloader and switch to DualBand GSM 900/1800. BUT then you CANNOT go in the BAND menu or it automatically switch you back into 900 ...

Advice Req. Make a US T-mobile work in Australia?

Hi, I have aquired a T-mobile from the U.S.
Before attempting to re-flash it to get it to work in Australia I just want some advice that I am about to do the right thing...
Here are its specs:-
Branded T-Mobile
ROM v 3.08.10ENG
Radio v 6.02
Model PW10B1
After some reading of these forums I have concluded it must be a 900/1900 GSM device, and it appears to be SIM locked.
(Here in Aus. we have a 900/1800 GSM system).
I intend to use a cooked rom from jeffs site to upgrade the rom.
Does the rom I use have to be one of the T-Mobile US roms ?
I realise that i wont have 1800 coverage. But will 900 still work?
Anyway, because of the sim lock I intend to proceed with a rom update.
I intend to:
Backup rom using SD card method
Download a V4.xxx T-mobile US cooked rom
Update rom using USB method
Any comments/advice appreciated (any local experience here?)
Regards from DownUnder.

well first off... i suggest you upgrade to Special rom 1.2 first.
that one will unlock your pda, so you can use it anywhere.
and about band... i'm sure i saw 1800 in the bootloader!
but not sure if you select it as default if it will carry over to the os
maybe worth a try.
in any case, if you back up your os onto SD, you have nothing to fear.
i say best thing to do, is copy that O2 os & radio (if you're sure u'll never leave australia, i dont think radios can be manipulated that often)
but dont take my word for it. wait for a confirmed user. if your not advanturous
Good Luck!

Yep, I backed up and upgraded to SE v1.2 rom using the SD card/OSImagetool method.
SIM unlocked ok
Phone works if 900mhz band is selected.
Its now thinks it's a model PW10A1.
Radio is still the 6.02 version. (B ver. )
Not sure what the consequences of this are.
Im not sure if i would benefit from a radio upgrade or not.
If I understand this correctly, I can ONLY upgrade the radio to the T-Mobile US versions, because the radio hardware is B version.
I think I will leave it like this for a while, see how it go's.
Anybody have any experience with using a B (US)version radio in a A Ver.(euro/asian) area.??

Thanks for the advice ntabikha and THANK YOU to the XDA Developers team.

Help!: How to differentiate between the Telstra HD2 and the UK variant

Quick question,
how can you tell which is which by looking at the phones? The HD2 i currently have has been flashed, so it shows t8525 in the settings, when i purchased it, it came in the telstra box but my 3G doesnt work (running on Rogers with a 4000 series sim card)
Is there any other way to see if its the telstra version? where can i check what bands are being used for data?
the rom im running is 1.66.405.2 wwe
Thanks!

Look on the back, towards the bottom. The Telstra version will say NextG Network and have a T logo.

awesome thank you

What Radio does the Official T-mobile UK 2.1 ROM use?

Hi all, Does anyone know which radio the official T-Mobile UK 2.1 RUU is using.
Cheers,
Higgsy

Menu->Settings->About Phone->Baseband version.

I am pretty sure it's the same one as the GSM unbranded one, which is the most recently made available one.
15.14 iirc

Yeah I know the radio I'm using, theory was that I would try the radio that the official T Mob RUU uses, as that one has been tested on T Mob. Pulser - cheers mate - might give that one a try, still using the old JU radio at the mo

Seems like T-Mobile UK are pushing a new one out via OTA. Did a fresh one last night and got.............
Baseband version - 63.18.55.06MU_6.35.13.09

Anyone know which radio for 3 UK is best ? Please provide a link to the latest. Updating radio loses root ?
