K Bikes Complex by Choice
Interesting. I'd believe more dealers don't want to be bothered - not that it can't be done. AFAIK - the software is actually dumped to the bike from a DVD. I think it's a case of lack of will, not lack of ability to do it.
I don't know if it is possible. I don't know if a previous version of CIP can replace a later version.
All of the SBs from BMW state that once programmed, the process cannot be reversed. This may only mean that the version present in the bike is not saved. So maybe the only way to reverse it would be to reload the earlier CIP software if possible.
I think you are right that the dealers probably don't want to be bothered with trying to reverse the flash unless they just have some personal interest in doing it.
