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

[Anonymous]

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.
