Flash T-Mobile Firmware back into SDA

[Guest Jelte86]

I have a T-Mobile SDA and recently I flashed it with the Qtek software with succes. Unfortunately my Tom Tom ain't working and I prefer to use my own language... so I would like to flash my T-Mobile Firmware back into my SDA.

Got the specific rom-update but when I try to update i'll get an error message that this firmware is not for my device. How can i fix this? Thanks in advance...

Well I fixed this to use TyphoonNbfTool to remove the provider field in the header data. Now I get a message that I can't upload an older ROM version.

How can I downgrade?

After ours of time I finnaly get installed the Orange SPV v4.1.1.4 UK software because that one should have a less destricted boot-loader.

But the problem is... Now I still can't update SDA 1.1.23.84 provided by jeijt, stil got the message invaled vender id/ only update!

What can i do now?

Have you tried this manual

At a certain point you have to switch to the Typhoon-NBF-tool to overcome the verdor ID problem

You mean this step:

6) In NBFTool, Choose Tools > Edit Header Data

7) Delete everything in the Operator field (where it says something weird - just delete it)

I've done that... Then I still get Upgrade Only. The problem is I think that the latest SDA software is older dan the Orange 4.1.1.4 software. I have a newer software version, only that is an restore image on my storage card so I don't have an .nbf file of that where I could delete the operator field yn the header data.

Anyone an idea how I still can get my SDA software back on my phone? Need it because my phone must return back to T-Mobile for garuanty.
