Downgrading from Radio Stack 4.21.00

[gotonextlevel]

I upgraded to the wrong Radio Stack (4.21.00) version last week. Which was a bit silly on my part. I guess that there is no turning back to another Radio Stack? That is I wish to go back to the original AT&T stack.

Please your help in this matter would be much appreciated!!

You can get the needed files to revert back to the AT&T radio stack from
the below site:
http://www.my-siemens.com/com.aperto/MySiemens/Files/Addon/da/us/mw/mc/mc/ruuv1.11_cea.20.17wwe_aws.exe

Once you have it use Winzip to extact it then locate and copy the below
files to your devices windows root folder and run RSUpgrade.exe.

Needed upgrade files:
RSUpgrade.exe
RSUpgrade.cp64
monitor_ul_bs.map
monitor_ul_bs.m0

How about downgrading from T-Mobile 6.24 to 6.18? Do you have a link and easy instructions like you provided for the AT&T Radio ROM?

Thanks

If you're planing on downgrading back to T-Mobile 6.18 you might
as well upgrade to the AT&T stack its a lot better than 6.18.

Anyhow 6.18 isn't a separate upgrade like 6.24 its built-in the 3.14.40 ROM.

Hello Q
Will this revert my settings back to

Radio Version : 3.23.01 Original
Protocol Version: 32S54 Original ?

Thanks Qman!

I did not upgrade to 6.24 yet but was just wondering if there was a simple way to downgrade back if I did.

What is your opinion of going to 6.24? Besides the constant GPRS connection what other benefits are there?

Thanks

In opinion 6.24 was better than 6.18 but not as good as At&T's stack,
besides the constant GPRS connection you'll have improved power management (better battery life), improved GSM and GPRS.
