I recently reset my Droid Inc. and it restored back to 1.6.
Was wondering if there is any way to upgrade to 2.2.
A link would help here but it sounds like you installed a 2.1 stock rom. Did his video not tell you that it was 2.1 stock?
Assuming that this is a stock and not rooted you should get prompted to download the update OTA just like when it first came out.
I would try to flash it again. Or do a factor reset first. Per the guys video you should get prompted for updates almost immediately. I don't know what state that flash will leave the s register. Most true stock flashes should take you back to Secure ON.
I don't own an Incredible so someone else might know what the deal is.
