1) How big is this file?
2) Is it encrypted when it comes over the Toyota network or is it encrypted on this scantool device?
Cool stuff!!! I don't see why it would take so long to update the software, unless it begins an entire diagnostic sequence to verify the loaded code. Hrmmm.. My hex editing dreams are seeming to be killed. Wish I could get that software somehow
3) How much is this scantool device?
There must be some I/O port. However, I assume it is using proprietary protocls because they think it is safer to protect from modification. I bet the security, if any, is weak should I be able to access the data -- it might be easy to change. Wondering...
