Is there a TPT image available for the OUK_P729BV1.0.0B08 stock ROM?

[Guest g-rasshopper]

Hi everyone,

First of all, please bear with me. I've been away from this forum for a long time so my knowledge might not be up to date.

I bought a San Francisco about 18 months ago and it came with the above ROM. I've experimented with various first generation ROMs but I've never been brave enough to upgrade my phone to Gen2 and try out some of the never ROMS.

I'm now about to take the plunge and install Swedish Snow (which is Gen2) using TPT. However, if something goes wrong, I'd like to have a simpe way of reverting my phone back to its factory settings. Presumably I could find a TPT image that converts my phone back to Gen1 and then install the OUK_P729BV1.0.0B08 ROM. But I'm not 100% certain whether that would work. And in any case, I'd prefer to do the downgrade in all in one go using a TPT image. Does such an image exist, and if not, is it possible to create one?

Thanks for your help.
