Anyone with Anextek SP230 out there to copy ROM image from?

this is what happened:
1) I found ROM Image of Rover S1 (apparently Russian version of Anextek SP230/Audiovox PPC4100) here:
http://mamaich.kasone.com/fr_rover.htm
2) extracted the image into an installation version SP_K1112_230A.nb0 (total size 29Mb)
3) Installed new ROM, using the second NB0 file from PPC4100 ROM installation.
4) The phone does not boot up any more
5) Installed the old PPC4100 ROM back and at least it boots up and the PDA functions are working again (the phone as mentioned in the previous message does not work, of course).

Possible explanation and workaround:
The ROM installation requires two NB0 files (files for PPC4100 available in this forum). One for the main ROM, and probably the other as the extended ROM.
It appears that the both have to be the same version and you can't replace the other by another version.
Workaround: OSImageTool reads only 32Mb of the ROM Image. SP230/PPC4100 has 64Mb ROM. I can modify OSImageTool to read all 64Mb - therefore getting both NB0 files.
However - anyone with with SP230 to copy ROM from out there? I'll modify the tool at once if someone would run it their phone and upload the ROM.
Of course, this would also be the tool to unlock all the PPC4100/SP230 there are out there.
