Hi,
I am using the 1.11 Rom. Unfortunately, my mdac's audio quality suffers from a kind of distortion. You almost cannot hear it, when somebody speaks soft, but as soon as it gets a little louder it is not very pleasing to the ears.
I tried to have it repaired, but they could not find anything.
So, I had the lady at the T-Mobile shop in my town make a test call.
She immediately noticed the distorted sound. We also changed the SIM to a new one, but it did not help.
So, finally, they would swap the thing toworrow.
But, as I stated....
So, is it possible at the moment to downgrade to a German ROM (T-Mob Germany or even better T-Mob Austria?)
I also want to add that my brother owns the same device, but he still has the German Rom, only the radio update to 1.05 was made...
Thanks for your answers and help, Günter

well, sure you can downgrade... no problem in doing that!

it's the same steps when upgrading but instead of upgrading the new rom use the old one.....!

the only problem is that it seems almost impossible to get an original T-Mobile ROM. But if you have a brother...

@pietrucci:
You mean, I can make an image of my brother's mdac's rom?
And then put it back on my mdac?
Is that possible?

Yes it is! You need ntrw.exe (v 2.0) and a sd-card. With the ntrw tool you can write your brothers ROM onto your computer (if you have a sister with a MDA, you can use that one too! I mean her MDA, not your sister herself ofcourse). And with the same ntrw tool you can make a bootable sd-card with this ROM. And then put it on the other machine. Look in this forum, there are several threads. For example, look at today's thread: http://forum.xda-developers.com/viewtopic.php?t=19500

@pietrucci:
Thank you (concerning my sister, unfortunately I don't have one).
I decided to go with my mda til the T-Mob Update which hopefully should be out in April (they didn't say 2005.)
It got a little better with my new SIM, and the guy in the shop allowed me to use his device, same shitty audio quality (of course, he had no Radio Update :wink: )
So again, thank you very much
