Additional Infos.

Only use. If SW Build is too old for 3GSwup.

U can identify it in different ways.
1.
*#06#
Look on SW Build. Most not working on old proto/sample

2.

Code:

000 000
Call

Enter 6 x 0 and enter Call.

Look under Phone info. Most too short to identify correct...

3. Better use Tools like HWTP, QPST ....

U can see such SW Builds on SXG75 like:
W6250C-MMTO-1.4.33_8
This is latest known SVN 26

MMTO is sign for Multiboot concept.

MMTZ like in W6250C-MMTZ-1.2.30 is also working with 3GSwup. Maybe not all Versions...

But Danger! If u see MMSZ like in W6250C-MMSZ-0.3.301T

Then you need QPST! And all files I told! Or you kill SXG75 with 3GSwup...

EVER make NV item Backup before. With QPST or better NV Editor as *.QCN or *.BRT.
After override partition you need to Restore NV items!
